python 使用代理访问网站遇到的问题

Question

源码如下

import requests

# 代理ip请求测试网站
url = "http://myip.ipip.net/"
# 封装请求头
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36'}

# 封装代理ip参数值：协议/ip/端口
proxy = {'http': 'http//117.91.249.179'}
# 发送请求
response = requests.get(url=url, headers=headers, proxies=proxy, timeout=10)
print(response.status_code)  # 打印请求返回的状态码
# 获取响应数据
response_data = response.text
# 把请求之后的获取到的响应数据保存到本地文件夹，以查看代理请求是否成功！
with open('ip.html', 'w', encoding='utf-8') as adi:
    adi.write(response_data)
exit()  # 代码执行完毕退出程序

我猜出问题的原因是这个，但是不知道怎么解决他，有没有大佬帮帮咱，谢谢啦

 

Answer 1

代理没有设置端口

# 端口要配置，否则默认80，一般代理端口不会是80的
proxy = {'http': 'http//ip:port'}
