How do I send a POST request using the Python Requests Library?
To send a POST request using Python Requests Library, you must call the requests.post(url, data = my_data) method and specify the target URL as the first parameter and the POST data as the second parameter. You must also specify the data type in the body of the POST message, using the Content-Type request header, so that the server can correctly accept and process the sent data. In this Python requests post example, the Content-Type: application/json header indicates that the body of the POST message contains JSON, and the Accept: application/json request header tells the server that the client is expecting a JSON in response.
Python Requests is a very popular library for sending HTTP requests in python. It greatly simplifies the process of working with HTTP requests in python. The Requests library is very flexible and can send any type of HTTP request using POST, GET and DELETE methods, upload files, post JSON and XML, and submit HTML forms. The code written using the Python Requests library is simple and easy to read. Although Python has a built-in urllib3 module for handling HTTP requests with similar functionality, almost everyone uses the Requests library because of its simplicity and convenience.
Python POST example using the Requests Library
Below is an example of posting an HTML form using the Python Requests library.
In this post HTML form example, the import requests directive imports the Requests library to our python code. The headers["Content-Type"] = "application/x-www-form-urlencoded" line sets the MIME type to application/x-www-form-urlencoded for the data in the body of POST message and requests.post(url, headers=headers, data=data) line sends data to the server.
Posting JSON data with the Requests library is also very easy. To do this, you need to set Content-Type to application/json and pass JSON to requests.post() method.
In this post JSON example, we also send the Accept: application/json request header to tell the server that our client is expecting JSON. Without this header, the server may return data in a different format.
Uploading files using Python Requests Library is also very easy.
