Python Requests Post Status Code
When working with APIs, you may often need to send data to the server using the POST method. The requests
library in Python makes it easy to do this. In this article, we will discuss how to make a POST request using requests
and how to handle the status code returned by the server.
Making a POST Request
To make a POST request using requests
, you can use the post()
method. Here is an example:
import requests
url = 'https://example.com/api/create_user'
data = {'username': 'john_doe', 'email': '[email protected]'}
response = requests.post(url, data=data)
print(response.status_code)
In this example, we are making a POST request to the URL https://example.com/api/create_user
and sending data in the form of a dictionary. The post()
method returns a Response
object. We can access the status code of the response using the status_code
attribute of the object.
Handling Status Codes
The status code returned by the server indicates whether the request was successful or not. It is important to handle different status codes appropriately in your code. Here are some common status codes and what they mean:
- 200 OK: The request was successful.
- 201 Created: The resource was created successfully.
- 400 Bad Request: The request was malformed or invalid.
- 401 Unauthorized: Authentication failed or user does not have permissions for the requested operation.
- 404 Not Found: The requested resource was not found.
- 500 Internal Server Error: An error occurred on the server.
To handle different status codes, you can use conditional statements in your code. Here is an example:
import requests
url = 'https://example.com/api/create_user'
data = {'username': 'john_doe', 'email': '[email protected]'}
response = requests.post(url, data=data)
if response.status_code == 200:
print('User created successfully.')
elif response.status_code == 400:
print('Invalid request.')
elif response.status_code == 401:
print('Authentication failed.')
else:
print('An error occurred.')
In this example, we are checking the status code of the response and printing an appropriate message based on the code.
Conclusion
In this article, we discussed how to make a POST request using requests
in Python and how to handle the status code returned by the server. It is important to handle different status codes appropriately in your code to ensure that your application works correctly.
