How to replace IP anti-blocking with Python crawler

As a technician who has been rooted in the dynamic ip solution of the crawler industry for a long time, I found that many people often encounter a problem when using Python crawlers, that is, how to change the IP address. Don't worry, today I will teach you how to change the IP in the Python crawler, so that your crawler will no longer be troubled by IP blocking. Don't talk nonsense, hurry up and learn with me!

First of all, we need to understand why the IP address needs to be changed.

When we frequently send requests to the same website, the website can easily detect our behavior and even block our IP address. At this time, we need to change the IP address to bypass the blockade to continue crawling.

Next, for the HTTP crawler ip, let me talk about how to change the IP in the Python crawler.

Step 1: Obtain the crawler ip address

You need to choose a reliable crawler ip provider, and choose the appropriate HTTP crawler ip according to your needs.

Step 2: Use the crawler ip to send the request

In Python crawlers, we generally use the requests library to send HTTP requests. The following is an example showing how to use the crawler ip in the requests library to send requests:

import requests

url = 'http://www.example.com'
proxy = {
    
    
    'http': 'http://your_proxy_ip:your_proxy_port',
    'https': 'https://your_proxy_ip:your_proxy_port'
}
response = requests.get(url, proxies=proxy)

print('请求结果：', response.text)

In this example, you need to replace your_proxy_ipand your_proxy_portwith the crawler ip address and port you actually obtained.

Step 3: Switch the crawler ip

If you wish to change the IP address, just put the new crawler ip address into proxythe dictionary. Here is an example showing how to switch crawler ip in Python crawler:

import requests

url = 'http://www.example.com'
proxy1 = {
    
    
    'http': 'http://proxy1_ip:proxy1_port',
    'https': 'https://proxy1_ip:proxy1_port'
}
proxy2 = {
    
    
    'http': 'http://proxy2_ip:proxy2_port',
    'https': 'https://proxy2_ip:proxy2_port'
}

# 第一次请求
response1 = requests.get(url, proxies=proxy1)
print('第一次请求结果：', response1.text)

# 切换爬虫ip
response2 = requests.get(url, proxies=proxy2)
print('第二次请求结果：', response2.text)

In this example, you need to replace proxy1_ip, proxy1_port, proxy2_ipand proxy2_portwith the crawler ip address and port you actually obtained.

So let's summarize:

1. Choose a reliable crawler ip provider like me and get the HTTP crawler ip address.

2. Use the crawler ip address to send requests in the Python crawler.

3. If you need to change the IP address, just put the new crawler ip address into proxythe dictionary.
