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.

What is the content type of Python httpx?

The content type of Python httpx library is a modern and efficient HTTP client library that provides an intuitive API for sending HTTP requests and interacting with web services.

At its core, httpx is designed to be a drop-in replacement for the popular requests library, but with additional features and performance optimizations. Here are some of the key content types that httpx supports:

Example:

import httpx
response = httpx.get('https://example.com/api/data', json={'key': 'value'})
print(response.text)  # prints the response body as a string

Example:

import httpx
response = httpx.get('https://example.com/api/image', params={'id': '123'})
print(response.content)  # prints the response body as a bytes object

Example:

import httpx
import json
response = httpx.post('https://example.com/api/create', json={'name': 'John', 'age': 30})
print(response.json())  # prints the response body as a JSON object

Example:

import httpx
response = httpx.post('https://example.com/api/login', data={'username': 'john', 'password': 'pass'})
print(response.text)  # prints the response body as a string

Example:

import httpx
from io import BytesIO
file = BytesIO(b'Hello, World!')
response = httpx.post('https://example.com/api/upload', files={'file': ('test.txt', file)})
print(response.text)  # prints the response body as a string

Example:

import httpx
response = httpx.get('https://example.com/api/image', params={'id': '123'})
print(response.content)  # prints the response body as a bytes object

In summary, httpx provides a flexible and powerful way to interact with web services and APIs, supporting a range of content types including text, binary, JSON, form, multipart, and bytes.
