Python httpx example

Python httpx example

I'm happy to respond in English! Here's an example of using the httpx library in Python:

What is httpx?

httpx is a fast, modern alternative to the popular requests library for making HTTP requests in Python. It was created by Alexey Kuzmin and is designed to be faster, more reliable, and easier to use than requests.

Installing httpx

To install httpx, you can use pip:

pip install httpx

Making a Simple Request

Here's an example of making a simple GET request using httpx:

import httpx
url = "https://www.example.com"
response = httpx.get(url)
print(response.status_code)  # prints the status code (e.g. 200)
print(response.text)  # prints the response text (HTML, JSON, etc.)

In this example, we import httpx and then use the get() function to send a GET request to the specified URL. The response variable contains the HTTP response object, which has properties like status_code and text.

Sending POST Requests

Here's an example of making a POST request using httpx:

import httpx
url = "https://www.example.com/submit"
data = {"name": "John", "age": 30}
response = httpx.post(url, json=data)
print(response.status_code)  # prints the status code (e.g. 200)
print(response.text)  # prints the response text (HTML, JSON, etc.)

In this example, we send a POST request to the specified URL with some JSON data in the request body.

Handling Cookies

httpx also supports handling cookies:

import httpx
url = "https://www.example.com/login"
data = {"username": "user", "password": "pass"}
response = httpx.post(url, json=data)
Get the cookie
cookie_name = "my_cookie"
cookie_value = response.cookies[cookie_name]
Use the cookie in a subsequent request
url = "https://www.example.com/protected"
headers = {"Cookie": f"{cookie_name}={cookie_value}"}
response = httpx.get(url, headers=headers)
print(response.status_code)  # prints the status code (e.g. 200)
print(response.text)  # prints the response text (HTML, JSON, etc.)

In this example, we send a POST request to log in with some credentials and get a cookie back. We then use that cookie in a subsequent GET request to access a protected resource.

Error Handling

httpx also supports error handling:

import httpx
url = "https://www.example.com/nonexistent"
try:
response = httpx.get(url)
except httpx.RequestError as e:
print(f"Error: {e}")
print(response)  # will be None if the request failed

In this example, we try to make a GET request to a non-existent URL and catch any RequestError exceptions that may occur. If the request fails, the response variable will be None.

I hope this helps! Let me know if you have any questions or need further assistance.

Python, httpx, and GitHub

Hey there! Let's talk about Python, httpx, and GitHub.

Python

Python is a high-level, interpreted programming language that is widely used for various purposes such as web development, scientific computing, data analysis, artificial intelligence, and more. It was created in the late 1980s by Guido van Rossum and has since become one of the most popular programming languages in the world.

Some of Python's key features include:

httpx

httpx is a Python library that makes it easy to send HTTP requests and interact with web servers. It's designed to be fast, flexible, and easy to use. With httpx, you can:

Here's an example of how you might use httpx to send a GET request:

import httpx
response = httpx.get('https://api.example.com/data')
print(response.json())  # prints the JSON response

GitHub

GitHub is a web-based platform for version control and collaboration. It's primarily used for managing code repositories, tracking changes to those repositories, and collaborating with other developers.

Some of GitHub's key features include:

Putting it all together

Now that we've covered Python, httpx, and GitHub, let's see how we can use these three things together!

Suppose you're building a web scraper using Python, and you need to send an HTTP request to retrieve some data. You might use httpx to make the request and then parse the response using a JSON library.

Here's an example of how you might do this:

import httpx
import json
response = httpx.get('https://api.example.com/data')
data = json.loads(response.json())
print(data)  # prints the parsed JSON data

In this example, we use httpx to send a GET request and then parse the response using the json library.

To store your code on GitHub, you can create a new repository and commit your changes. You can also invite others to collaborate on the project or fork someone else's repository to make it your own.

I hope this helps! Let me know if you have any questions or need further clarification.
