Send Parameters in URL using Python Requests

Python Requests - Send Parameters in URL

To send parameters in URL, write all parameter key:value pairs to a dictionary and send them as params argument to any of the GET, POST, PUT, HEAD, DELETE, or OPTIONS requests.

If
{'param1': 'value1', 'param2': 'value2'} are the parameters, and
https://somewebsite.com/ is the URL, then https://somewebsite.com/?param1=value1&param2=value2 would be our final URL.

Examples

1. Send Parameters in URL using Python Requests

In the following example, we are sending a parameter in the URL with a GET request. To check if the URL is formatted correctly, you can print it from the response object using response.url as shown in the below program.

Python Program

import requests

params = {'p': '9431'}
response = requests.get('https://pythonexamples.org/',
            params=params)
print(response.url)

Explanation:

  1. The params dictionary contains the parameters you want to send in the URL.
  2. The requests.get() method is used to send the GET request with the parameters appended to the URL.
  3. response.url will print the final URL, including the parameters.

Output

https://pythonexamples.org/?p=9431

2. When the URL gets Redirected

In the following example, we will send a parameter, where the final URL gets redirected.

Python Program

import requests

params = {'p': '943'}
response = requests.get('https://pythonexamples.org/',
            params=params)
print(response.url)

Explanation:

  1. The request is sent to https://pythonexamples.org/?p=943 with the params.
  2. Since the resource at that URL redirects to another page, the final URL will be different from the original one.
  3. The response.url will give the final redirected URL.

Output

https://pythonexamples.org/python-requests-http-get/

3. Send Parameters with POST Request

You can also send parameters with a POST request. This can be useful when you need to send parameters in the body of the request.

Python Program

import requests

params = {'username': 'user123', 'password': 'securepassword'}
response = requests.post('https://pythonexamples.org/login', params=params)
print(response.url)

Explanation:

  1. Here, the parameters username and password are included in the request URL.
  2. When the request is processed, the response.url will show the URL with the parameters appended.

Output

https://pythonexamples.org/login?username=user123&password=securepassword

Summary

In this Python Tutorial, we learned how to send parameters in the URL using the requests module. We saw how to send parameters with GET requests, handle redirects, and even use them with POST requests.
