Python – Send HTTP POST Request
HTTP POST request is used to create or update a resource in a specified server.
In Python Requests library, requests.post() 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.
Examples
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 = requests.post('https://pythonexamples.org/', data = {'key':'value'})
Run Code Copyrequests.post() returns a Response object. It contains all the data and properties like response content, headers, encoding, cookies, etc. Let us print out headers.
Python Program
import requests
response = requests.post('https://pythonexamples.org/',
data = {'key1':'value1', 'key2':'value2'})
print(response.headers)
Run Code CopyOutput
