Python Requests Post Response JSON

Python is one of the most popular programming languages that is widely used for various purposes, including web development, data analysis, and machine learning. One of its powerful libraries is the Requests module, which allows us to send HTTP/1.1 requests in Python. In this article, we will discuss how to work with Python Requests Post Response JSON.

What is Requests Module in Python?

The Requests module is a Python library that allows you to send HTTP/1.1 requests using Python. It provides an easy-to-use interface for sending HTTP/1.1 requests and handling responses. The module is built on top of the urllib3 library and provides support for features like keep-alive, connection pooling, and authentication.

What is Post Request in Requests Module?

The POST method is used to submit an entity to the specified resource, often causing a change in state or side effects on the server. In other words, a POST request is used to send data to a server to create or update a resource. The data sent to the server is usually in JSON format, which is a lightweight data format that is easy to read and write for humans and machines.

How to Send a POST Request with JSON Payload using Requests Module?

Here is an example of how to send a POST request with a JSON payload using the Requests module:


import requests

url = 'https://example.com/api/create_user'
data = {'username': 'johnDoe', 'password': '1234'}

response = requests.post(url, json=data)

print(response.json())
  • The first step is to import the Requests module.
  • Then, we define the URL to which we want to send the POST request.
  • Next, we define the data that we want to send to the server. In this case, it is a dictionary containing the username and password.
  • We then use the requests.post() method to send the POST request to the server. We pass the URL and data as arguments to this method.
  • The response from the server is stored in the response variable.
  • Finally, we print the JSON response returned by the server using response.json() method.

How to Handle Response in JSON Format?

The response returned by the server is usually in JSON format. To handle this response, we need to use the json() method provided by the requests module. The json() method returns a Python dictionary that contains the JSON response data.


import requests

url = 'https://example.com/api/get_user'
data = {'id': '1234'}

response = requests.post(url, json=data)

user_data = response.json()
print('User ID:', user_data['id'])
print('User Name:', user_data['name'])
print('User Email:', user_data['email'])
  • In this example, we are sending a POST request to retrieve user data from a server.
  • We pass the user ID as data to the server using JSON format.
  • The response from the server is stored in the response variable.
  • We then extract the JSON data from the response using the json() method and store it in the user_data variable.
  • Finally, we print the user's ID, name, and email address from the user_data dictionary.

Conclusion

In this article, we have discussed how to work with Python Requests Post Response JSON. We have learned how to send a POST request with JSON payload using the requests module and how to handle the JSON response returned by the server. The Requests module provides an easy-to-use interface for sending HTTP/1.1 requests and handling responses, making it a great choice for building web applications and APIs in Python.
