Sending GET Request with Python Requests Library

What is the Python Request Library?

Requests Library is a popular library for sending HTTP requests (POST, GET, DELETE, etc) in Python. The Requests library provides a set of handly methods that make it easy to work with HTTP protocol. The Requests library can automatically validate server SSL certificates, supports Client-Side certificates, and has built-in support for International Domain Names, URLs, and Unicode response bodies. The Requests Library makes it easy to send GET and POST requests to protected resources that require Basic or Digest user authentication, can automatically handle session cookies, and automatically decompress the response content. Python has a built-in urllib3 module for handling HTTP requests with similar functionality, but almost all use Python Requests as the code is simple and easy to read. However, the Requests Library is not included in the Python distribution.

What is HTTP GET request?

The GET request method is used to request a resource from the server using the provided URL. The HTTP GET method is one of nine standard methods of Hypertext Transfer Protocol (HTTP). The GET method should only be used to retrieve data from the server. GET requests cannot send data to the server in the body of a GET message and cannot change the server's state. If you want to change data on the server, use POST, PUT, PATCH, or DELETE methods.

GET /echo HTTP/1.1
Host: reqbin.com
Accept: */*

How to install the Python Requests Library?

print(r.text)

How to send user authentication credentials with Python GET Request?
