Python Requests Library for HTTP2

Python Requests library is a powerful and user-friendly HTTP client library used for making HTTP requests in Python programming. It provides a simple and elegant way to interact with web services and APIs. The Requests library supports both HTTP and HTTPS protocols and is capable of handling various HTTP request methods such as GET, POST, PUT, DELETE, HEAD, and OPTIONS.

What is HTTP2?

HTTP2 is the next-generation HTTP protocol that is designed to improve the web performance by reducing the latency and enhancing the security of the communication between web browsers and servers. HTTP2 is based on Google's SPDY protocol and it uses several advanced features such as multiplexing, server push, header compression, and stream prioritization to achieve better performance.

How to use Python Requests Library for HTTP2?

To use Python Requests library for HTTP2, you need to install an additional package called "hyper" which is a pure-Python implementation of the HTTP2 protocol. You can install the "hyper" package using pip command:


pip install hyper

Once you have installed the "hyper" package, you can use it to create an HTTP2 session with the server as follows:


import requests
from hyper.contrib import HTTP20Adapter

url = 'https://example.com'

session = requests.Session()
session.mount(url, HTTP20Adapter())

response = session.get(url)

print(response.text)

In the above example, we have imported the requests module and the HTTP20Adapter class from the hyper.contrib package. We have created a session object using the requests.Session() constructor and then mounted an instance of the HTTP20Adapter class to the specified URL. Finally, we have made an HTTP2 GET request to the server and printed the response text.

Alternative Method using "httpx" Library

Another way to use Python Requests library for HTTP2 is to use the "httpx" library which is a fully featured HTTP client for Python that supports both HTTP and HTTP2 protocols. You can install the "httpx" package using pip command:


pip install httpx

Once you have installed the "httpx" package, you can use it to make HTTP2 requests as follows:


import httpx

url = 'https://example.com'

response = httpx.get(url, http2=True)

print(response.text)

In the above example, we have imported the httpx module and made an HTTP2 GET request to the specified URL using the httpx.get() function with the "http2=True" argument. Finally, we have printed the response text.
