歪歪用的是python3，基于python3写代码还是感觉挺可以的，但是突然遇见了一件事，就是网站对ip的检测，当我们用ip进行过多反访问时，网站可能检测到，所以我们需要一个给代码添加一个代理，废话不多说，直接看代码，其实还挺简单的
import random
import requests
def a():
pro=['61.135.217.7:80','58.53.128.83:3128','58.218.201.188:58093','175.148.74.17:1133','118.190.95.35:9001',]
proxies={'http': random.choice(pro)}
print (proxies)
head = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36'}
url = 'http://www.baidu.com/' # 你用于测试自己ip的网站
request = requests.get(url, proxies=proxies, headers=head) # 让问这个网页 随机生成一个ip
request.encoding = request.apparent_encoding
# 设置编码 encoding 返回的是请求头编码 apparent_encoding 是从内容网页中分析出的响应内容编码方式
print(request.text) # 输出返回的内容
if __name__ == '__main__':
for i in range(0,20):
a()
如上代码，用requests模块进行的网络访问，当然还可以用其他的，差别不大，重点在于random.choice() 达到代理的随机选取，附上xici的代理筛选
import requests
import re
import random
url='http://www.xicidaili.com/nn'
headers = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.3'
'6 (KHTML, like Gecko) Ubuntu Chromium/56.0.2924.7'
'6 Chrome/56.0.2924.76 Safari/537.36'}
def files(ip):
f0=open('1.txt',"a")
s=f0.write(str(ip)+"\n")
f0.close()
def get_user_agent():
''' 功能: 随机获取UA :return: 返回一个随机UA '''

不过此代码只能简单挑选ip，还需自己逐个验证，还待修改。
