Python Requests – HTTP POST

Python – Send HTTP POST Request

HTTP POST request is used to create or update a resource in a specified server.

In Python Requests library, method is used to send a POST request to a server over HTTP. You can also send additional data in the POST request using data parameter.

Example 1: Send HTTP POST Request

In this example, we shall send a POST request to the server with given URL.

Python Program

import requests

response ='', data = {'key':'value'})
Run returns a Response object. It contains all the data and properties like response content, headers, encoding, cookies, etc. Let us print out headers.

import requests

response ='',
            data = {'key1':'value1', 'key2':'value2'})
