Python Requests Post with Username and Password

Posting data to a website is a common task when working with web applications. In Python, the Requests library makes this task easy. In this article, I will explain how to make a POST request with username and password using Python Requests library.

Step 1: Install Requests Library

If you haven't already done so, you will need to install the Requests library. To install Requests, you can use pip command in your terminal:

    pip install requests

Step 2: Import Required Libraries

Now that we have installed Requests, we can import it into our Python script along with other required libraries:

    import requests
    import json

Step 3: Create a Dictionary with Username and Password

We need to create a dictionary containing the username and password that we want to post:

    login_data = {'username': 'myusername', 'password': 'mypassword'}

Step 4: Send the POST Request

We can now use the Requests library to send a POST request to the website:

    url = 'https://www.example.com/login/'
    response = requests.post(url, data=json.dumps(login_data), headers={'Content-Type': 'application/json'})

We are sending the data as JSON, so we need to set the Content-Type header to application/json. The response variable will contain the server's response to our POST request.

Step 5: Check the Response

We can check the server's response to our POST request by printing the response content:

    print(response.content)

If we receive a successful login message, we can consider our POST request successful.

Summary

In this article, we learned how to make a POST request with username and password using Python Requests library. We covered the installation of the Requests library, importing required libraries, creating a dictionary containing the username and password, sending the POST request, and checking the server's response.

      # Complete code
      import requests
      import json
      
      login_data = {'username': 'myusername', 'password': 'mypassword'}
      
      url = 'https://www.example.com/login/'
      response = requests.post(url, data=json.dumps(login_data), headers={'Content-Type': 'application/json'})
      
      print(response.content)
