Python httpx.put() Guide: HTTP PUT Requests

Python's httpx library is a powerful tool for making HTTP requests. Among its methods, httpx.put() is used to send HTTP PUT requests. This guide will explain how to use it effectively.

What is httpx.put()?

The httpx.put() method sends a PUT request to a specified URL. PUT requests are used to update or replace existing resources on a server. They are idempotent, meaning multiple identical requests will have the same effect.

If you're new to HTTP requests, you might want to check out our guide on Python httpx.get() for a basic understanding of making HTTP requests.

Installing httpx

Before using httpx.put(), you need to install the httpx library. If you haven't installed it yet, follow our step-by-step guide to get started.

Basic Syntax of httpx.put()

The basic syntax for httpx.put() is straightforward. Here's how it looks:

import httpx

response = httpx.put(url, data=None, json=None, headers=None)

In this syntax:

• url: The URL where the PUT request is sent.
• data: Optional. The data to send in the request body.
• json: Optional. A JSON object to send in the request body.
• headers: Optional. A dictionary of HTTP headers to send with the request.

Example: Using httpx.put()

Let's look at a practical example. Suppose you want to update a user's information on a server. Here's how you can do it:

import httpx

url = "https://example.com/api/users/1"
data = {"name": "John Doe", "email": "john.doe@example.com"}
headers = {"Content-Type": "application/json"}

response = httpx.put(url, json=data, headers=headers)
print(response.status_code)
print(response.json())

In this example, we send a PUT request to update the user with ID 1. The server responds with a status code and the updated user data.

Handling Responses

After sending a PUT request, you can handle the response. The response object contains useful information like status code, headers, and content.

For example, to check if the request was successful, you can use:

if response.status_code == 200:
    print("Update successful!")
else:
    print("Failed to update.")

You can also access the response content using response.json() or response.text.
