Add parameter to url python

Question

Why

I've been not satisfied with all the solutions on this page (come on, where is our favorite copy-paste thing?) so I wrote my own based on answers here. It tries to be complete and more Pythonic. I've added a handler for dict and bool values in arguments to be more consumer-side (JS) friendly, but they are yet optional, you can drop them.

How it works

Test 1: Adding new arguments, handling Arrays and Bool values:

url = 'http://stackoverflow.com/test'
new_params = {'answers': False, 'data': ['some','values']}

add_url_params(url, new_params) == \
    'http://stackoverflow.com/test?data=some&data=values&answers=false'

Test 2: Rewriting existing args, handling DICT values:

url = 'http://stackoverflow.com/test/?question=false'
new_params = {'question': {'__X__':'__Y__'}}

add_url_params(url, new_params) == \
    'http://stackoverflow.com/test/?question=%7B%22__X__%22%3A+%22__Y__%22%7D'

Talk is cheap. Show me the code.

Code itself. I've tried to describe it in details:

from json import dumps

try:
    from urllib import urlencode, unquote
    from urlparse import urlparse, parse_qsl, ParseResult
except ImportError:
    # Python 3 fallback
    from urllib.parse import (
        urlencode, unquote, urlparse, parse_qsl, ParseResult
    )


def add_url_params(url, params):
    """ Add GET params to provided URL being aware of existing.

    :param url: string of target URL
    :param params: dict containing requested params to be added
    :return: string with updated URL

    >> url = 'http://stackoverflow.com/test?answers=true'
    >> new_params = {'answers': False, 'data': ['some','values']}
    >> add_url_params(url, new_params)
    'http://stackoverflow.com/test?data=some&data=values&answers=false'
    """
    # Unquoting URL first so we don't loose existing args
    url = unquote(url)
    # Extracting url info
    parsed_url = urlparse(url)
    # Extracting URL arguments from parsed URL
    get_args = parsed_url.query
    # Converting URL arguments to dict
    parsed_get_args = dict(parse_qsl(get_args))
    # Merging URL arguments dict with new params
    parsed_get_args.update(params)

    # Bool and Dict values should be converted to json-friendly values
    # you may throw this part away if you don't like it :)
    parsed_get_args.update(
        {k: dumps(v) for k, v in parsed_get_args.items()
         if isinstance(v, (bool, dict))}
    )

    # Converting URL argument to proper query string
    encoded_get_args = urlencode(parsed_get_args, doseq=True)
    # Creating new parsed result object based on provided with new
    # URL arguments. Same thing happens inside of urlparse.
    new_url = ParseResult(
        parsed_url.scheme, parsed_url.netloc, parsed_url.path,
        parsed_url.params, encoded_get_args, parsed_url.fragment
    ).geturl()

    return new_url

Please be aware that there may be some issues, if you'll find one please let me know and we will make this thing better

I was recently trying to automate adding a query parameter to a bunch of URLS and came across a neat approach a long way down this StackOverflow answer, that uses the PreparedRequest class from the requests library.

Let’s first get the class imported:

from requests.models import PreparedRequest
req = PreparedRequest()

And now let’s use use this class to add a query parameter to a URL. We can do this with the following code:

url = "http://www.neo4j.com"
params = {'ref':"mark-blog"}
req.prepare_url(url, params)

And then we need to access the url attribute to see our new URL:

>>> req.url
'http://www.neo4j.com/?ref=mark-blog'

Neat! We can also use this approach to add parameters to URLs that already have existing ones. For example, we could update this YouTube URL:

url = "https://www.youtube.com/watch?v=Y-Wqna-hC2Y&list=RDhlznpxNGFGQ&index=2"
params = {'ref':"mark-blog"}
req.prepare_url(url, params)

And let’s see what the updated URL looks like:

>>> req.url
'https://www.youtube.com/watch?v=Y-Wqna-hC2Y&list=RDhlznpxNGFGQ&index=2&ref=mark-blog'

I’m sure I’ll be using this code snippet in future!

What is a URL query string?

A typical URL looks very much like a system file path, e.g.

 http://www.example.com/index.html

A query string is a convention for appending key-value pairs to a URL. The standard URL for the New York Times's website's New York section is this:

  http://www.nytimes.com/section/nyregion

However, if you click on the New York tab via the nytimes.com homepage, you'll notice that a whole bunch of characters are appended to the URL:

 http://www.nytimes.com/section/nyregion?action=click&pgtype=Homepage

The question mark ? denotes the separation between the standard URL and the query string. Everything after that is a key value pair, with each pair separated by an ampersand, &. The equals sign = is used to separate key and value.

So the key-value pairs in the above query string are:

key	value
action	click
pgtype	Homepage

Or, more to our purposes, this is what those keypairs would look like as a dictionary:

{
  'action': 'click',
  'pgtype': 'Homepage'
}

What do those actually do? That's actually a question we can't answer, unless we're running the nytimes.com servers. Though it's safe to assume that the NYT uses the query string in its analytics, so that it can tell how many people visited http://www.nytimes.com/section/nyregion via the homepage and by clicking on some button.

Other web services have query strings that serve a more obvious purpose. For example, DuckDuckGo, which has this URL endpoint:

  https://www.duckduckgo.com/

However, if we append a key-pair value as a query string, with q being the key (think of it as an abbreviation for "query") and the value being the term we want to search for, e.g. Stanford, then DuckDuckGo will return search results for Stanford:

  https://www.duckduckgo.com/?q=Stanford

Invalid characters for URLs

It's hard to tell these days because modern web browsers allow us to literally type in anything from the keyboard. Unless we prepend the input with http://, the text is just sent as is to Google or DuckDuckGo or whatever your default search engine is.

However, this is just a convenient illusion. When we type into your browser bars, say, something with a whitespace character, e.g.

  Stanford University

Before sending it to the search engine, the web browser will actually serialize it as:

  Stanford%20University

This is because whitespace characters are not allowed in URLs, so the token %20 is used to represent it. Basically, almost everything that is not an alphanumeric character needs to have this special encoding.

In the olden days, you'd have to remember how to do these encodings or else the browser would throw you an error. Now, the browser just fixes it for you, not unlike an auto spellchecker.

How Python's urllib handles invalid URL characters

Of course, when programming in Python, things still work like the olden days – i.e. we're forced to be _explicit.

Here's what happens when you use the urlretrieve method that comes via Python's built-in module urllib.request:

from urllib.request import urlretrieve
thing = urlretrieve("https://www.duckduckgo.com/?q=Stanford University")

An error is raised:

HTTPError: HTTP Error 400: Bad Request

We have to throw in the %20 ourselves to avoid the error:

thing = urlretrieve("https://www.duckduckgo.com/?q=Stanford%20University")

Using urllib.parse.quote to escape invalid characters

Trying to remember which characters are invalid, nevermind manually escaping them with percent signs, is a maddening task. That's why there's a built-in Python module – urllib.parse – that contains an appropriate method: quote.

Try it out via interactive Python – note that parse doesn't actually do any URL requesting itself – it is a method that does one thing and one thing well: making strings safe for URLs:

>>> from urllib.parse import quote
>>> quote("Stanford University")
'Stanford%20University'
>>> quote("I go to: Stanford University, California!")
'I%20go%20to%3A%20Stanford%20University%2C%20California%21'

In combination with the previously-tried urlretrieve method:

from urllib.request import urlretrieve
from urllib.parse import quote
qstr = quote("Stanford University")
thing = urlretrieve("https://www.duckduckgo.com/?q=" + qstr)

Serializing dictionaries into query strings

In the previous example, having to type out that q= should also seem tedious to you. Once again, urllib.parse has a method for that: urlencode.

Try it out in interactive Python:

>>> from urllib.parse import urlencode
>>> mydict = {'q': 'Stanford University, whee!!!'}
>>> urlencode(mydict)
'q=Stanford+University%2C+whee%21%21%21'

Note that the urlencode method includes the functionality of the quote function, so you probably rarely need to call quote on its own. Also note that urlencode uses the plus sign to encode a space character in a URL…which is basically as valid as using %20. Again, the confusing rules and standards are yet another reason to delegate this string parsing to the proper Python libraries.

And, again, urlencode does not actually fetch the URL. We still have to use urlretrieve:

from urllib.request import urlretrieve
from urllib.parse import urlencode
mydict = {'q': 'whee! Stanford!!!', 'something': 'else'}
qstr = urlencode(mydict)
# str resolves to: 'q=whee%21+Stanford%21%21%21&something=else'
thing = urlretrieve("https://www.duckduckgo.com/?" + qstr)

Note that we also have to include the ?, which is always used to set off the query string from the first part of the URL.

Also note that programatically fetching search queries via DuckDuckGo (or Google, for that matter)…is not very effective. I just use it as an example so that you can see what the URL turns out to be and test it in your browser.

Requests to the rescue

What about the Requests library, which we've been using to fetch URLs for the most part? Well, true to its slogan of being "HTTP for Humans", the Requests library neatly wraps up all that urllib.parse functionality for us.

Just use the requests.get method with a second argument (the name of the argument is params):

import requests
url_endpoint = 'https://www.duckduckgo.com'
mydict = {'q': 'whee! Stanford!!!', 'something': 'else'}
resp = requests.get(url_endpoint, params=mydict)

Trying out Google Static Maps

Let's work with a more fun, visual API: the Google Static Maps API

(For more information on Google Static Maps API, check out: Visualizing Geopolitical Sensitivities with the Google Static Maps API)

A review of the static maps parameters

As with most APIs, Google Static Maps starts out with a URL endpoint:

https://maps.googleapis.com/maps/api/staticmap

At a minimum, it requires a size parameter, with a value in the format of WIDTHxHEIGHT:

https://maps.googleapis.com/maps/api/staticmap?size=600x400

Here's what that map looks like:

Let's add another parameter: zoom

  https://maps.googleapis.com/maps/api/staticmap?size=600x400&zoom=4

And let's change where the map is centered around with the center parameter, which takes any string that describes a human-readable location:

https://maps.googleapis.com/maps/api/staticmap?size=600x400&zoom=8&center=Chicago

Or, we can pass in a latitude/longitude pair:

https://maps.googleapis.com/maps/api/staticmap?size=600x400&zoom=8&center=42,-70

Adding markers

Maybe you're thinking: this is easy, handcoding the URL parameters. Let's do something tricky. The markers parameter lets us add markers to the map. It takes a location string (just like center):

https://maps.googleapis.com/maps/api/staticmap?size=600x400&markers=Stanford,CA

However, the API allows for the marking of multiple points (hence, the parameter plural name of "markers"). The standard for URL query strings when multiple values have the same key is to repeat the key, In other words, to show markers for both Stanford,CA and Chicago, we include this in the query string:

  markers=Stanford,CA&markers=Chicago

e.g.

https://maps.googleapis.com/maps/api/staticmap?size=600x400&markers=Chicago%7Ccolor:blue%7Csize:tiny

Customizing the style of markers

Because both style information and location information is delimited via the pipe character, style information must appear first in any marker descriptor. Once the Google Static Maps API server encounters a location in the marker descriptor, all other marker parameters are assumed to be locations as well.

By default, the map markers are red. To make a marker green, this is what the markers value is set to:

  markers=color:green|Chicago

e.g.

https://maps.googleapis.com/maps/api/staticmap?size=600x400&markers=color:green|Chicago

![https://maps.googleapis.com/maps/api/staticmap?size=600x400&markers=color:green

Chicago](https://maps.googleapis.com/maps/api/staticmap?size=600x400&markers=color:green

Chicago)

We can also change the icon's size. And give it a letter. Here's the value for a blue icon for Chicago, with a label consisting of the letter "X":

  markers=color:blue|label:X|Chicago

![https://maps.googleapis.com/maps/api/staticmap?size=600x400&markers=color:blue

label:X

Chicago](https://maps.googleapis.com/maps/api/staticmap?size=600x400&markers=color:blue

label:X

Chicago)

Technically, while the URL examples above will work in a modern browser, pipe characters aren't allowed in URLs. They should be escaped with %7C:

markers=color:blue%7Clabel:X%7CChicago

If that's not convoluted/ugly enough for you, the Google Maps API lets you use custom icons. Here's how to make a marker using President Obama's face (found at the following URL:

http://www.compciv.org/files/images/randoms/obamaicon.png

The corresponding markers value:

markers=icon:http://www.compciv.org/files/images/randoms/obamaicon.png

However, as you can imagine, some of those characters in the URL are not allowed as is in the query string. Think about it; we're putting a URL inside another URL…how would a primitive browser easily parse that? The URL example above is pretty simple, but since URLs can contain any number of strange characters, we should assume many of those characters will have to be encoded in that percent-fashion. From the Google API's explanation:

Note: The multiple levels of escaping above may be confusing. The Google Chart API uses the pipe character (|) to delimit strings within its URL parameters. Since this character is not legal within a URL (see the note above), when creating a fully valid chart URL it is escaped to %7C. Now the result is embedded as a string in an icon specification, but it contains a % character (from the %7C mentioned above), which cannot be included directly as data in a URL and must be escaped to %25. The result is that the URL contains %257C, which represents two layers of encoding. Similarly, the chart URL contains an & character, which cannot be included directly without being confused as a separator for Google Static Maps API URL parameters, so it too must be encoded.

This is what the URL ends up being:

https://maps.googleapis.com/maps/api/staticmap?size=600x400&markers=icon:http%3A//www.compciv.org/files/images/randoms/obamaicon.png%7CChicago

And here's Obama's head, floating over Chicago:

Programmatically create query strings for Google Static Maps API

OK, now that we've seen how to do things the painful and old-fashioned way, let's use the urllib.parse.urlencode method to do the painful work of creating the URL query strings.

First, let's import urlencode and set up the constants, i.e. the variables that won't change:

from urllib.parse import urlencode
import webbrowser
GMAPS_URL = 'https://maps.googleapis.com/maps/api/staticmap?'

Importing webbrowser is optional. But it allows you to conveniently test out the URLs from your Python code:

import webbrowser
url = "https://maps.googleapis.com/maps/api/staticmap?size=600x400"
webbrowser.open(url)

(You should be doing this in interactive Python)

Here we go.

Basic Google Static Maps API URL

Only the size parameter needs to be specified:

mydict = {'size': '600x400'}
url = GMAPS_URL + urlencode(mydict)
# https://maps.googleapis.com/maps/api/staticmap?size=600x400

Adding zoom

This is simply another key-value pair in the dictionary:

mydict = {'size': '600x400', 'zoom': 4}
url = GMAPS_URL + urlencode(mydict)
# https://maps.googleapis.com/maps/api/staticmap?size=600x400&zoom=4

Adding center

Again, just another key-value pair

mydict = {'size': '600x400', 'zoom': 9, 'center': 'Stanford, California'}
url = GMAPS_URL + urlencode(mydict)
# https://maps.googleapis.com/maps/api/staticmap?center=Stanford%2C+California&zoom=4&size=600x400

Adding markers

markers is just another key-value pair, when we're just adding a single marker:

(note that I've removed the center param…the Google Static Maps API is smart enough to just auto-center the map around the marker)

mydict = {'size': '600x400', 'zoom': 14, 
          'markers': 'CoHo Café at Stanford'}
url = GMAPS_URL + urlencode(mydict)
# https://maps.googleapis.com/maps/api/staticmap?markers=CoHo+Caf%C3%A9+at+Stanford&zoom=14&size=600x400

Using urlencode's doseq parameter to specify a list of values

OK, adding multiple markers is where things get slightly complicated. We can represent a list of location strings by using, well, a list of strings:

locations = ['Stanford, CA', 'Berkeley, CA']

However, we must call urlencode with the doseq argument set to True (try omitting the argument to see what results on your own):

locations = ['Stanford, CA', 'Berkeley, CA']
mydict = {'size': '600x400', 'markers': locations}
url = GMAPS_URL + urlencode(mydict, doseq=True)
# https://maps.googleapis.com/maps/api/staticmap?markers=Stanford%2C+CA&markers=Berkeley%2C+CA&size=600x400

Just for fun, serialize a bunch of locations into a Google Static Maps URL:

pac12 = ['University of Arizona, AZ',
            'Arizona State University, AZ',
            'University of California, Berkeley, CA',
            'University of California, Los Angeles, CA',
            'University of Colorado Boulder, CO',
            'University of Oregon, OR',
            'Oregon State University, OR',
            'University of Southern California, CA',
            'Stanford University, CA',
            'University of Utah, UT',
            'University of Washington, WA',
            'Washington State University, WA']

mydict = {
  'size': '600x400','markers': pac12 
}

url = GMAPS_URL + urlencode(mydict, doseq=True)

The resulting image and URL:

Mapping earthquakes

It's not a lot of fun creating lists by hand. So let's use a list from an official government source: the USGS Earthquake Hazards program.

The example below is a demonstration of the csv module and the DictReader function, which can be used to create a list of dictionaries from a CSV file.

import csv
import requests
from urllib.parse import urlencode
import webbrowser

USGS_URL = 'http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/significant_month.csv'
resp = requests.get(USGS_URL)
lines = resp.text.splitlines()
earthquakes = csv.DictReader(lines)
coordinate_pairs = []
for quake in earthquakes:
    coordinate_pairs.append(quake['latitude'] + ',' + quake['longitude'])    
# create a URL based on Google Static Maps API specs
GMAPS_URL = 'https://maps.googleapis.com/maps/api/staticmap'
query_string = urlencode(
                {'size': '800x500', 'markers': coordinate_pairs}, 
                doseq=True)
url = GMAPS_URL + '?' + query_string
webbrowser.open(url)

Here's the resulting URL (as of February 9th, 2016):

Here's a slightly more cleaned-up version of the code that uses the Requests library to "prepare" a URL:


# slightly more Pythonic, cleaner version
from csv import DictReader
import requests
import webbrowser
USGS_URL = 'http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/significant_month.csv'
GMAPS_URL = 'https://maps.googleapis.com/maps/api/staticmap'
# get the USGS data, create a list of lines
lines = requests.get(USGS_URL).text.splitlines()

# get the latitude/longitude pairs
coordinate_pairs = ["%s,%s" % (q['latitude'], q['longitude']) for q in DictReader(lines)]

# this is another way of serializing the URL
preq = requests.PreparedRequest()
preq.prepare_url(GMAPS_URL, {'size':'800x500', 'markers': coordinate_pairs})
webbrowser.open(preq.url)

Let's make a function for mapping markers

Before we get into the tricky business of styling the markers, let's wrap up the functionality that we've been using to create a proper Google Static Maps URL into a function:

(assuming you've read the short guide on making functions: Function fundamentals in Python)

Here's a bare-bones implementation, in which a user only has to specify a list (or just a string, if there's only one location) of locations and, optionally, width and height. The foo_goo_url function does the work of serializing the input into proper Google Static Maps API format.

At the end, it returns the URL as a string object:

def foogoo_url(locations, width = 600, height = 400):
    from urllib.parse import urlencode
    gmap_url = 'https://maps.googleapis.com/maps/api/staticmap'
    size_str = str(width) + 'x' + str(height)
    query_str = urlencode({'size': size_str, 'markers': locations}, doseq=True)
    return gmap_url + '?' + query_str

Here's how you would use it, interactively:

>>> foogoo_url('New York, NY', height='200')
'https://maps.googleapis.com/maps/api/staticmap?markers=New+York%2C+NY&size=600x200'
>>> foogoo_url(['Wyoming', 'Alaska'])
'https://maps.googleapis.com/maps/api/staticmap?markers=Wyoming&markers=Alaska&size=600x400'

Testing out those URLs by pasting them into the web browser is so time-consuming. So let's make another function. This one doesn't return anything. Instead, it takes the same parameters as foogoo_url, but passes them directly into foogoo_url, and then passes the result of that into webbrowser.open, which performs the action of opening a webbrowser:

(note that this definition assumes that foogoo_url has been defined earlier)

def foogoo_browse(locations, width=600, height=400):
    import webbrowser
    url = foogoo_url(locations, width, height)
    webbrowser.open(url)

Styling markers

(Note: This section ends up veering out of plain URL creation and into application and function design…I end up not quite finishing it…)

This is where it gets tricky. As a reminder, markers takes a pipe-delimited string to separate the style configuration, e.g.

  markers=color:green|label:Z|Chicago

However, that's a convention of Google's own making, because they needed a way to do key-value pairs (e.g. label = Z) that is independent (or rather, nested) in the way that key-value pairs are done in URL query strings.

So basically, we have to hand-create the string ourselves:

marker_styles = {
    'color': 'orange',
    'label': 'X'
}
marker_config = []
for k, v in marker_styles.items():
    s = str(k) + ':' + str(v) 
    # e.g. 'color' + ':' + 'orange'
    marker_config.append(s)
# the location always comes last, as specified by the Google API
marker_config.append('Chicago')
# now join the list elements together as a pipe-delimited string
marker_string = '|'.join(marker_config)

The result of the code above would result in the marker_string variable pointing to a string like this:

color%3Aorange%7Clabel%3AX%7CChicago

Which we can then pass into the locations argument of our previously defined foogoo_url function:

foogoo_url(marker_string)

Which generates a URL like this:

https://maps.googleapis.com/maps/api/staticmap?markers=color%3Aorange%7Clabel%3AX%7CChicago&size=600x400

Defining the marker style certainly got complicated…it's so complicated that it probably deserve its own method.

Creating a create_styled_marker() function

I'm going to skip the full explanation, or bother even creating what I consider to be the best real-world implementation of a create_styled_marker function. We can cover it in another lesson, but the main takeaway is: look at how we can use functions and Python data structures, such as lists and dictionaries, to create text strings useful for communicating with other services.

Without further elaboration, here's how to turn the previous icon mapping code into a reusable function:

def create_styled_marker(location, style_options={}):
      mconfig = []
      for k, v in style_options.items():
          mconfig.append(str(k) + ':' + str(v))
      mconfig.append(location)
      return '|'.join(mconfig)

Note: if lists and dictionaries are old hat to you and you understand list comprehensions, as well as string formatting, here's a fancy pants Pythony-version:

def create_styled_marker(location, style_options={}):
      opts = ["%s:%s" % (k, v) for k, v in style_options.items()] 
      opts.append(location)
      return '|'.join(opts)

Here's all the relevant code to create a quickie-let's-make-a-Google-Static-Maps-API convenience wrapper, as one big script:

Note that I've drastically modified foogoo_url from the previous demonstration. See if you can untangle the reasoning…but it's not worth explaining in full since this isn't a lesson on application design…

from urllib.parse import urlencode
import webbrowser

def create_styled_marker(location, style_options={}):
      opts = ["%s:%s" % (k, v) for k, v in style_options.items()] 
      opts.append(location)
      return '|'.join(opts)


def foogoo_url(locations, width = 600, height = 400, maptype='terrain'):
    gmap_url = 'https://maps.googleapis.com/maps/api/staticmap'
    size_str = str(width) + 'x' + str(height)
    # note: this is messy, and it has more to do with opinions about interface
    # design than the core lesson...
    if type(locations) is not list:
        markers_objects = locations
    else:
        markers_objects = []
        for loc in locations:
            if type(loc) is str:
                obj = create_styled_marker(loc)
            else:
                obj = create_styled_marker(loc[0], loc[1])
            markers_objects.append(obj)
    #finally, make the query string
    mapopts =  {'size': size_str, 
                'markers': markers_objects,
                'maptype': maptype}
    query_str = urlencode(mapopts, doseq=True)
    return gmap_url + '?' + query_str

def foogoo_browse(locations, width=600, height=400):
    import webbrowser
    url = foogoo_url(locations, width, height)
