[已解决]关于IP查询实战遇到的问题

夏空彼方

使用https://www.ip138.com/网站查询自己的IP，网站编码格式是GBK
import urllib.request
import re
url1 = "https://www.ip138.com/"
def ipdet(url) :
    req = urllib.request.Request(url)
    req.add_header("User-Agent","Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.25 Safari/537.36 Core/1.70.3756.400 QQBrowser/10.5.4039.400")
    response = urllib.request.urlopen(req)
    html = response.read().decode("GBK")
    print(html)
    r= r'(?:(?:[0,1]?\d?\d|2[0-4]\d|25[0-5])\.){3}(?:[0,1]?\d?\d|2[0-4]\d|25[0-5])'
    ip = re.findall(r,html)
    print(ip)
ipdet(url1)
写的有点混乱,但是这样并没有得到IP地址，看了下html里面的元素也没有跟网站检查时的<a href="https://www.ip138.com/iplookup.asp?ip=110.184.65.14&amp;action=2" target="_top">110.184.65.14</a>这个标签
不知道怎么办求大佬看看

IP138的查询实际是走的是2020.ip138.com，你代码这样改：

1. import urllib.request
   
2. import re
   
3. 
   
4. url = "http://2020.ip138.com"
   
5. req = urllib.request.Request(url)
   
6. req.add_header("User-Agent","Firefox")
   
7. response = urllib.request.urlopen(req)
   
8. html = response.read().decode("utf-8")
   
9. ip = re.findall(r'您的IP地址是：(.*)<',html)
   
10. print(ip)

复制代码

下面是requests版：

1. import requests
   
2. import re
   
3. 
   
4. url = 'http://2020.ip138.com'
   
5. headers = {'user-agent': 'firefox'}
   
6. r = requests.get(url, headers=headers)
   
7. ip = re.findall(r'您的IP地址是：(.*)<',r.text)
   
8. print(ip)

网站和自己爬出来的不一样，可能是js动态渲染的页面，换个网址查吧：
https://httpbin.org/get

1. import urllib.request
   
2. import re
   
3. url1 = "https://httpbin.org/get"
   
4. def ipdet(url) :
   
5.     req = urllib.request.Request(url)
   
6.     req.add_header("User-Agent","Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.25 Safari/537.36 Core/1.70.3756.400 QQBrowser/10.5.4039.400")
   
7.     response = urllib.request.urlopen(req)
   
8.     html = response.read().decode("GBK")
   
9.     print(html)
   
10.     r= r'(?:(?:[0,1]?\d?\d|2[0-4]\d|25[0-5])\.){3}(?:[0,1]?\d?\d|2[0-4]\d|25[0-5])'
    
11.     ip = re.findall(r,html)
    
12.     print(ip)
    
13. ipdet(url1)
