Python中使用代理IP进行网站监测的实现方法

2023-04-17 00:00:00 方法 代理 监测
  1. 首先需要安装requests库,使用以下命令安装:

pip install requests

  1. 然后引入requests库和随机模块:

python import requests import random

  1. 定义代理IP池,可以从免费代理网站获取代理IP地址:

python proxy_list = [ 'http://ip1:port1', 'http://ip2:port2', 'http://ip3:port3', ... ]

  1. 定义请求头,一般需要添加User-Agent和Accept-Language:

python headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3', 'Accept-Language': 'zh-CN,zh;q=0.9', }

  1. 编写请求函数,并指定代理IP:

```python
def request(url):
# 随机选取一个代理IP
proxy = random.choice(proxy_list)
proxies = {'http': proxy, 'https': proxy}

   # 发送请求
   response = requests.get(url, headers=headers, proxies=proxies, timeout=10)

   # 返回响应内容
   return response.content

```

  1. 使用请求函数获取网站内容:

python url = 'http://pidancode.com' content = request(url) print(content.decode('utf-8'))

  1. 完整代码演示:

```python
import requests
import random

proxy_list = [
'http://ip1:port1',
'http://ip2:port2',
'http://ip3:port3',
...
]

headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3',
'Accept-Language': 'zh-CN,zh;q=0.9',
}

def request(url):
# 随机选取一个代理IP
proxy = random.choice(proxy_list)
proxies = {'http': proxy, 'https': proxy}

   # 发送请求
   response = requests.get(url, headers=headers, proxies=proxies, timeout=10)

   # 返回响应内容
   return response.content

url = 'http://pidancode.com'
content = request(url)
print(content.decode('utf-8'))
```
