How to use Socks5 proxy IP in crawler

Uh-huh! I hear you're using Socks5 to proxy IPs in your crawler? That's a good question! But don't worry, I'll explain it to you today, so you can easily learn how to use Socks5 proxy IP in the crawler!

What is Socks5 Proxy

Don't worry, we need to figure out what a Socks5 proxy is first. Well, a Socks5 proxy is a network protocol that forwards your requests through an intermediary server so that your real IP is hidden! In short, it's a superhero that protects your privacy!

Installation of related tools

First of all, we need to install some necessary tools in order to use Socks5 proxy IP in the crawler oh! So get your command line terminal open and follow me!
Start by installing Python's requests library, which is a very handy library that allows us to easily send HTTP requests. Use the following command to install it:

"`ipipgothon
pip install requests
“`

Next, we need to install a really awesome library called socks5, which allows us to use the Socks5 proxy in Python. Use the following command to install it:

"`ipipgothon
pip install ipipgosocks
“`

Okay, the tool installation is complete! And we can start having fun!

Using the Socks5 Proxy

With the tools in place, we can start using the Socks5 proxy! First, we have to create a proxy session and configure the proxy IP and port number accordingly. Here, look at the code example below:

import requests
import socks
import socket

socks.set_default_proxy(socks.SOCKS5, "127.0.0.1", 1080) # Proxy IP and Port Number
socket.socket = socks.socksocket

# Now we can happily send HTTP requests!
response = requests.get("https://www.example.com")
print(response.text)

See? With just a few lines of code, we successfully sent an HTTP request using a Socks5 proxy IP! It's almost like traveling to the other side of the internet!

Get Socks5 proxy IP

However, we certainly can't always use a local IP as a proxy yah! We need a real and valid Socks5 proxy IP, so before we start crawling, we need to find reliable resources to get a Socks5 proxy IP.

Solving common problems

When using Socks5 proxy, sometimes we encounter some problems. But don't worry, I have prepared some solutions to common problems here!

1. Proxy connection failure

When you can't connect using Socks5 proxy, it is possible that the proxy IP is blocked or there is something wrong with the proxy server. At this point, you need to either get a new proxy IP or try to connect to another available proxy server.

2. Slow agents

Sometimes, proxy servers can be slow, causing our crawler to be less efficient. At this time, you can try to connect to other faster proxy servers or use multi-threaded asynchronous requests to improve efficiency.

3. Captcha issues

在使用代理IP时，有时候你会碰到需要输入验证码的情况。这时候，你需要编写相应的代码来自动处理验证码。可以使用一些第三方库，如ipipgotesseract来进行验证码识别，或者是使用一些打码平台来自动解决验证码问题。

summarize

Through the learning of this article, you have mastered the skills of how to use Socks5 proxy IP in the crawler! Don't you feel relieved? Move your fingers and try to use Socks5 Proxy IP to enhance your crawler! Remember, it takes adventure to discover a better world! Cheer up!
