当发送带有身份验证的请求时，我会得到一个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，我使用了verify=False作为requests.get()参数之一，但是得到了一个requests.exceptions.ProxyError错误，如下所示：

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)

我疲于寻找答案，但似乎没有什么效果。我不能用带有身份验证的代理发送请求。有什么想法吗？

proxy

python-requests

python

ssl

问题很可能不是身份验证。不幸的是，您没有提供代理配置和用于代理的URL的详细信息。你提供的唯一东西是：

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访问代理与为 HTTPS使用HTTP 不同。当通过HTTPS代理访问HTTPS URL时，实际上对代理进行双重加密：

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

而对于“普通”HTTP代理上的HTTPS URL，只有一种加密，即它看起来(简化)如下：

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

您想要使用的代理很可能是一个普通的HTTP代理，而不是HTTPS代理。这实际上是最常见的情况。

发生此错误的原因是代理不能说TLS，而是被TLS访问。修复方法是使用http://proxy而不是https://proxy作为代理地址。请注意，后者适用于较早版本的Python，因为不支持HTTPS上的代理，协议的https://值与http://相同。

在python3.9版本中，我的脚本也有类似的问题。当我试图从web服务器获取一些数据时，出现了如下异常：

urllib3.exceptions.MaxRetryError

简单地添加这一行以配置请求

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

我希望这能帮你解决问题
