Python Requests Post Headers Example

If you are working with APIs or web applications, you might need to send a POST request to the server with some information. POST method is used to submit a form or to send data to the server. In Python, you can use the Requests library to send HTTP requests. In this post, I will show you how to send a POST request with headers using Python Requests.

Step 1: Install Requests Library

If you don't have the Requests library installed, you can install it using pip:

pip install requests

Step 2: Import Requests Library

You need to import the requests library to use it:

import requests

Step 3: Send POST Request with Headers

The syntax for sending a POST request with headers using Requests library is:

response = requests.post(url, data=data, headers=headers)
  • url: The URL of the server where you want to send the POST request.
  • data: The data you want to send along with the POST request. It can be a dictionary or a string.
  • headers: The headers you want to send along with the POST request. It should be a dictionary.

Let's say you want to send a POST request to a server with some JSON data and set some headers. Here is an example:

import json

url = 'https://example.com/api/'
data = {'name': 'John', 'age': 30}
headers = {'Content-type': 'application/json', 'Authorization': 'Bearer YOUR_ACCESS_TOKEN'}

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

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

In this example, we are sending a POST request to 'https://example.com/api/' with JSON data {'name': 'John', 'age': 30} and headers {'Content-type': 'application/json', 'Authorization': 'Bearer YOUR_ACCESS_TOKEN'}. The data is converted to JSON format using the json.dumps() function. The response is printed to the console after the request is sent.

Multiple Ways to Send Headers

There are multiple ways to send headers using Requests library:

  • Pass headers as a dictionary in the headers parameter:
headers = {'Content-type': 'application/json', 'Authorization': 'Bearer YOUR_ACCESS_TOKEN'}
response = requests.post(url, data=data, headers=headers)
  • Pass headers as a list of tuples in the headers parameter:
headers = [('Content-type', 'application/json'), ('Authorization', 'Bearer YOUR_ACCESS_TOKEN')]
response = requests.post(url, data=data, headers=headers)
  • Use the request.headers property to set headers:
response = requests.post(url, data=data)
response.headers['Content-type'] = 'application/json'
response.headers['Authorization'] = 'Bearer YOUR_ACCESS_TOKEN'

Conclusion

In this post, I showed you how to send a POST request with headers using Python Requests library. You learned how to install Requests library, import it, and send a POST request with headers using the requests.post() method. I also showed you multiple ways to send headers using Requests library. I hope you found this post helpful.
