Python Requests Post Try Except

If you are working with Python, then you might come across a situation where you need to make a POST request to a server. In such cases, the Python Requests library is a popular choice to make HTTP requests. However, while making these requests, you might encounter errors. This is where the try-except block comes in handy.

Python Requests Library

The Python Requests library is used to make HTTP requests in Python. It is a popular choice because it is easy to use, well documented, and supports many features such as authentication, cookies, and sessions.

POST Request

POST request is a type of HTTP request method that is used to send data to the server.

Try-Except Block

The try-except block is used to catch and handle exceptions. In Python, when an error occurs, an exception is raised. The try block contains the code that is being executed, and the except block contains the code that is executed when an exception is raised.

Example Code


import requests

url = 'https://example.com/api/v1/users'
data = {'name': 'John', 'email': '[email protected]'}

try:
    response = requests.post(url, data=data)
    response.raise_for_status()
    print(response.text)
except requests.exceptions.HTTPError as err:
    print(err)

In this example code, we are making a post request to the specified URL with the data provided. The try block contains the code that makes the request. The response.raise_for_status() line checks if the request was successful by checking the status code of the response. If the status code is not in the range of 200-299, it raises an HTTPError exception. The except block contains the code that prints the error message if an exception is raised.

Alternative Way

Another way to catch exceptions while making post requests with Python Requests is to use the response.ok attribute. The response.ok attribute returns True if the status code of the response is in the range of 200-299, and False otherwise. Here's an example:


import requests

url = 'https://example.com/api/v1/users'
data = {'name': 'John', 'email': '[email protected]'}

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

if response.ok:
    print(response.text)
else:
    print(response.status_code)

In this example code, we are making a post request to the specified URL with the data provided. We then check if the request was successful by checking the response.ok attribute. If response.ok returns True, we print the text of the response. If it returns False, we print the status code of the response.
