What is HTTP Methods and its types?

HTTP (Hypertext Transfer Protocol) is a protocol for transmitting data over the internet. It defines a set of methods that indicate the desired action to be performed on a specific resource.

The most commonly used HTTP methods are:

GET: Retrieves information about a resource. 

Example:

import requests

response = requests.get("https://jsonplaceholder.typicode.com/users/1")

print(response.json())

POST: Submits information to be processed by the resource identified by the URI. 

Example: 

    import json

    import requests

    data = {

        "name": "John Doe",

        "email": "johndoe@example.com"

    }

    headers = {'Content-type': 'application/json'}

    response = requests.post("https://jsonplaceholder.typicode.com/users",

data=json.dumps(data), headers=headers)

    print(response.status_code)

PUT: Replaces all current representations of the target resource with the request payload. 

Example: 

 

  import json

    import requests

    data = {

        "name": "John Doe",

        "email": "johndoe@example.com"

    }

    headers = {'Content-type': 'application/json'}

    response = requests.post("https://jsonplaceholder.typicode.com/users",

data=json.dumps(data), headers=headers)

    print(response.status_code)

PATCH: Partially updates a resource. 

Example: 

   

import json

    import requests

    data = {

        "email": "johndoe@example.com"

    }

    headers = {'Content-type': 'application/json'}

    response = requests.patch("https://jsonplaceholder.typicode.com/users/1",

data=json.dumps(data), headers=headers)

    print(response.status_code)

DELETE: Deletes a resource. 

Example: 

   

import requests

    response = requests.delete("https://jsonplaceholder.typicode.com/users/1")

    print(response.status_code)

HEAD: Same as GET, but only returns the headers, not the resource itself. Example: HEAD /users/123

OPTIONS: Describes the communication options for the target resource. Example: OPTIONS /users

CONNECT: Establishes a tunnel to the server identified by the target resource.

TRACE: Performs a message loop-back test along the path to the target resource.

The last one is HTTP Method is HTTP2 (HTTP/2) is a major revision of the HTTP network protocol used by the World Wide Web. 

It was developed to reduce the latency and overhead of HTTP.
