Python Requests Post Auth

Python requests module is widely used for making HTTP requests. It provides an easy-to-use interface for sending HTTP/1.1 requests using Python. In this article, we will discuss how to send POST requests with authentication using python requests.

Authentication

Authentication is the process of verifying the identity of a user or process. It is an important part of secure communication. In HTTP, authentication is done using different methods such as Basic, Digest, OAuth, etc. In this article, we will discuss Basic authentication.

Python Requests Post Auth Example

The following is a simple example of sending a POST request with basic authentication:


import requests

url = 'https://example.com/api/v1/login'
data = {'username': 'username', 'password': 'password'}

response = requests.post(url, data=data, auth=('username', 'password'))

print(response.status_code)
print(response.json())

In the above example, we are sending a POST request to the login API endpoint with the username and password as data. We are also providing the authentication details in the auth parameter of the post method.

Multiple Ways to Do Python Requests Post Auth

There are several ways to send POST requests with authentication using Python Requests:

  • Using auth parameter with the post method
  • Using HTTPBasicAuth class
  • Using headers parameter with the post method

Using auth parameter with the post method

The auth parameter of the post method can be used to provide the authentication details:


import requests

url = 'https://example.com/api/v1/login'
data = {'username': 'username', 'password': 'password'}

response = requests.post(url, data=data, auth=('username', 'password'))

print(response.status_code)
print(response.json())

Using HTTPBasicAuth class

The HTTPBasicAuth class can be used to create an authentication object which can be passed to the post method:


import requests
from requests.auth import HTTPBasicAuth

url = 'https://example.com/api/v1/login'
data = {'username': 'username', 'password': 'password'}
auth = HTTPBasicAuth('username', 'password')

response = requests.post(url, data=data, auth=auth)

print(response.status_code)
print(response.json())

Using headers parameter with the post method

The headers parameter of the post method can be used to provide the authentication details in the Authorization header:


import requests

url = 'https://example.com/api/v1/login'
data = {'username': 'username', 'password': 'password'}
headers = {'Authorization': 'Basic base64_encode(username:password)'}

response = requests.post(url, data=data, headers=headers)

print(response.status_code)
print(response.json())

In the above example, we are encoding the username and password in base64 and providing it in the Authorization header.

Conclusion

Python Requests module provides an easy-to-use interface for sending HTTP requests. In this article, we discussed how to send a POST request with authentication using Python Requests. We also discussed different ways to provide the authentication details.
