The httpx HTTP client package in Python stands out as a versatile tool for developers, providing robust support for both HTTP and SOCKS5 proxies. This capability allows for more flexible and efficient management of network requests, ensuring that your applications can navigate the complexities of the internet with ease. For those looking to integrate advanced web scraping functionalities into their projects, turning to a best web scraping API can further enhance your ability to access and extract valuable data from the web. With the right combination of httpx’s proxy support and a powerful web scraping API, developers can create sophisticated applications that leverage the full potential of the internet. Below is a guide on implementing proxies with httpx:

import httpx
from urllib.parse import quote

# Example proxy configurations:
# Direct HTTP proxy without authentication:
my_proxy = ""
# SOCKS5 proxy:
my_proxy = "|socks5"
# HTTP proxy with authentication (ensure credentials are URL encoded):
my_proxy = "http://my_username:my_password@"
# For credentials containing special characters:
my_proxy = f"http://{quote('')}:{quote('password@123')}@"

# Setting up proxies in httpx:
proxies = {
    'http://': '',  # For all HTTP URLs
    'https://': '',  # For all HTTPS URLs
    # Proxy for specific domains:
    '': '',

# Using the proxy with httpx.Client
with httpx.Client(proxies=proxies) as client:
    response = client.get("")

# Asynchronous usage with httpx.AsyncClient
async with httpx.AsyncClient(proxies=proxies) as client:
    response = await client.get("")

Proxies can also be configured via standard environment variables, adhering to the *_PROXY naming convention:

$ export HTTP_PROXY=""
$ export HTTPS_PROXY=""
$ export ALL_PROXY="socks://"
$ python
import httpx
# This will utilize the environment-configured proxies
with httpx.Client() as client:
    response = client.get("")
