Python Requests Post Send JSON Data

As a programmer, I have used Python requests module for sending HTTP requests to servers and receiving responses. One of the most common use cases is sending JSON data in the POST request. In this post, I will explain how to send JSON data using Python requests module.

Python Requests Module

Python requests module is a simple yet powerful HTTP library that makes it easy to interact with web services. It is designed to be easy to use and has a simple API that allows developers to send HTTP requests and receive responses. The requests module can be installed using pip, which is a package manager for Python.


pip install requests

Using Python Requests Post Method to Send JSON Data

The post method of the requests module is used to send data in the HTTP request body. Here is an example of how to send JSON data using the post method:


import requests

url = 'https://example.com/api'
data = {'name': 'John Doe', 'age': 30}

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

print(response.status_code)
print(response.json())

In the above example, we have defined a URL and a dictionary containing the data we want to send. We have then used the post method of the requests module to send the JSON data in the request body. The json parameter of the post method is used to set the content type header to application/json and serialize the data as JSON.

The response object returned by the post method contains the response from the server. We can access the status code and response data using the status_code and json methods respectively.

Alternative Way to Send JSON Data

Another way to send JSON data using Python requests module is by setting the content type header to application/json and serializing the data as a string. Here is an example:


import requests
import json

url = 'https://example.com/api'
data = {'name': 'John Doe', 'age': 30}

headers = {'Content-type': 'application/json'}
json_data = json.dumps(data)

response = requests.post(url, data=json_data, headers=headers)

print(response.status_code)
print(response.json())

In the above example, we have defined a URL, a dictionary containing the data we want to send, and a header with the content type set to application/json. We have then serialized the data as a JSON string using the dumps method of the json module. Finally, we have used the post method of the requests module to send the JSON data in the request body.

Conclusion

Python requests module is an easy-to-use HTTP library that allows developers to send HTTP requests and receive responses. Sending JSON data using the requests module is a common use case, and it can be achieved in multiple ways. In this post, we have discussed how to send JSON data using the post method of the requests module and by setting the content type header to application/json.
