如何绕过python请求SSL和代理错误?

Question

当发送带有身份验证的请求时，我得到一个requests.exceptions.SSLError错误，您可以看到下面。

proxies = { 'https' : "http://user:pass@ip:port/" } 
url = "https://httpbin.org/ip"
numberResponse = requests.get(url,proxies=proxies).text
print(numberResponse)

requests.exceptions.SSLError

所以我累了verify=False作为request .get()参数之一，但随后得到一个request .exceptions. proxyerror错误，你可以看到下面:

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)

我试图寻找答案，但似乎没有工作。我不能用代理发送请求身份验证。什么好主意吗?

Answer 1

问题很可能不在于身份验证。不幸的是，您没有提供代理配置的详细信息和代理使用的URL。您提供的唯一东西是:

proxies = { 'https' : eampleIpWithAuth } 

基于对堆栈跟踪中_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。注意，通过访问代理HTTPS不同于为使用HTTP代理HTTPS。当通过HTTPS代理访问HTTPS URL时，本质上是对代理进行双重加密:

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

而使用"normal"HTTP代理只有单一加密，即它看起来(简化)像这样:

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

很可能你想使用的代理是一个普通的HTTP代理，而不是HTTPS代理。这实际上是最常见的情况。

由于代理不能使用TLS，但可以通过TLS访问而发生错误。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

我在python 3.9版本的脚本中遇到了类似的问题。当我试图从web服务器获取一些数据时，我有例外，如您的:

urllib3.exceptions.MaxRetryError

简单添加这行来配置您的请求

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

我希望，这有助于解决您的问题
