【问题描述】：

我尝试向代理发送 python 请求，但失败了。我做错了什么？

代码如下：

import requests
url = 'https://httpbin.org/ip'

proxies = {
    "http": 'http://103.250.153.242',
    "https": 'http://103.250.153.242'
}

response = requests.get(url,proxies=proxies)
print(response.json())

结果应该返回 {'origin': '103.250.153.242'} 但我得到了这个：

Traceback (most recent call last):
  File "C:\Python37\lib\site-packages\urllib3\connection.py", line 160, in _new_conn
    (self._dns_host, self.port), self.timeout, **extra_kw)
  File "C:\Python37\lib\site-packages\urllib3\util\connection.py", line 80, in create_connection
    raise err
  File "C:\Python37\lib\site-packages\urllib3\util\connection.py", line 70, in create_connection
    sock.connect(sa)
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

我该如何解决这个问题？

【解决方案1】：

import urllib
import requests

r = requests.get('http://google.com', proxies=urllib.request.getproxies())

但是如果你有代理列表：

from urllib3 import ProxyManager, make_headers

default_headers = make_headers(proxy_basic_auth='myusername:mypassword')
http = ProxyManager("https://myproxy.com:8080/", headers=default_headers)

# Now you can use `http` as you would a normal PoolManager
r = http.request('GET', 'https://stackoverflow.com/')

或者：

import requests
proxies = {
    'http': 'http://proxy.server:port',
    'https': 'http://proxyserver:port',
}
s = requests.Session()
s.proxies = proxies
r = s.get('https://api.ipify.org?format=json').json()

【讨论】：

使用第二种方法（带请求），您在哪里输入代理授权凭据？

【解决方案2】：

你有这些代理：

proxies = {
  "http": 'http://103.250.153.242',
  "https": 'http://103.250.153.242'
}

但这不正确，因为IP没有端口号，只需添加您对这个ip的端口，没有其他端口。它会是这样的：

proxies = {
  "http": 'http://103.250.153.242:PORT',
  "https": 'http://103.250.153.242:PORT'
}
