如何绕过 python 请求 SSL 和代理错误？

Question

发送带有身份验证的请求时，我收到 requests.exceptions.SSLError 错误，您可以在下面看到。

proxies = { 'https' : "http://user:pass@ip:port/" } 

url = "https://httpbin.org/ip"

numberResponse = requests.get(url,proxies=proxies).text

print(numberResponse)

requests.exceptions.SSLError

然后我厌倦了 verify=False 作为 requests.get() 参数之一，但随后得到一个 requests.exceptions.ProxyError 错误，您可以在下面看到：

proxies = { 'https' : "http://user:pass@10.10.1.10:3128/"} 

url = "https://httpbin.org/ip"

numberResponse = requests.get(url,proxies=proxies,verify=False).text

print(numberResponse)

我厌倦了寻找答案，但似乎没有任何效果。我无法使用代理发送请求 验证。有什么想法吗？

Answer 1

问题很可能不是身份验证。不幸的是，您没有提供代理配置的详细信息以及您用于代理的 URL。您唯一提供的是：

proxies = { 'https' : eampleIpWithAuth } 

基于堆栈跟踪中对_connect_tls_proxy 的引用，eampleIpWithAuth 很可能类似于https://...，即您尝试通过 HTTPS 访问代理本身。请注意，通过 HTTPS 访问代理与使用 HTTPS 的HTTP 代理不同。当通过 HTTPS 代理访问 HTTPS URL 时，实际上是对代理进行双重加密：

client --- [HTTPS wrapped inside HTTPS] --- proxy --- [HTTPS] --- server

而通过“普通”HTTP 代理的 HTTPS URL 只有单一加密，即看起来（简化）如下：

client --- [HTTPS wrapped inside HTTP]  --- proxy --- [HTTPS] --- server

您要使用的代理很可能是纯 HTTP 代理，而不是 HTTPS 代理。这其实是最常见的情况。

由于代理无法使用 TLS 但被 TLS 访问，因此发生错误。解决方法是使用http://proxy 而不是https://proxy 作为代理地址。请注意，后者在旧版本的 Python 中工作，因为不支持通过 HTTPS 的代理，并且该协议的值 https:// 被视为与 http:// 相同。

Answer 2

我的脚本在 python 3.9 版本中遇到了类似的问题。 当我尝试从网络服务器获取一些数据时，我遇到了您的异常：

urllib3.exceptions.MaxRetryError

简单的添加这一行来配置你的请求

import requests
import urllib3
requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS = 'ALL:@SECLEVEL=1'

我希望这可以帮助您解决您的问题
