Post Requests Python Headers

HTTP headers are used to pass additional information between the client and the server. Headers can be used by both the client and the server to pass information in the form of key-value pairs. Python provides the requests module which allows us to send HTTP requests using Python.

Creating a POST Request with Headers

When creating a POST request with headers, we first need to import the requests module:


import requests

We can then create a dictionary containing the headers we want to send:


headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3',
    'Content-Type': 'application/json'
}

The above dictionary contains two key-value pairs. The first key-value pair specifies the user agent, and the second key-value pair specifies the content type.

We can then make a POST request using the requests.post() method:


response = requests.post('https://example.com/api', headers=headers, json={'data': 'example'})

The above code sends a POST request to the specified URL with the headers and JSON data. We can access the response status code and content using the following code:


status_code = response.status_code
content = response.content

Multiple Ways to Send Headers

There are multiple ways to send headers in a POST request using Python. One way is to pass the headers as a dictionary to the requests.post() method, as shown above.

Another way is to use the headers parameter of the requests.post() method:


response = requests.post('https://example.com/api', headers={'Content-Type': 'application/json'}, json={'data': 'example'})

The above code sends a POST request to the specified URL with only one header (Content-Type).

We can also use the HTTPAuthentication class from the requests module to send headers:


from requests.auth import HTTPBasicAuth

response = requests.post('https://example.com/api', auth=HTTPBasicAuth('user', 'pass'), json={'data': 'example'})

The above code sends a POST request to the specified URL with basic authentication headers.

Conclusion

Python's requests module provides a simple and easy way to send HTTP requests with headers. There are multiple ways to send headers in a POST request, depending on our specific requirements.
