问题描述

发送带有身份验证的请求时，我收到一个 requests.exceptions.SSLError 错误，您可以在下面看到.

When sending a request with authentication, I get a requests.exceptions.SSLError error which you can See below.

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

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

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

print(numberResponse)

requests.exceptions.SSLError

    raise MaxRetryError(_pool, url, error or ResponseError(cause))

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:

So then I tired verify=False as one of the requests.get() parameters but then get a requests.exceptions.ProxyError error which you can see below :

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?

I tired to look every for the answer but nothing seems to work. I can't send a request with a proxy with authentication. Any ideas?

推荐答案

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用于代理的 URL.您提供的唯一内容是:

The problem is very likely not the authentication. Unfortunately, you don't provide details of the proxy configuration and the URL you use for the proxy. The only thing you provide is:

proxies = { 'https' : eampleIpWithAuth }

根据堆栈跟踪中对 _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 访问代理与使用用于 HTTPS 的 HTTP 代理不同.当通过 HTTPS 代理访问 HTTPS URL 时，本质上是对代理进行双重加密:

Based on the reference to _connect_tls_proxy in the stacktrace the eampleIpWithAuth is very likely something like https://..., i.e. you try to access the proxy itself over HTTPS. Note that accessing a proxy over HTTPS is different from using a HTTP proxy for HTTPS. When accessing a HTTPS URL over a HTTPS proxy one essentially does double encryption to the proxy:

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

而使用普通"网址上的 HTTPS URLHTTP 代理只有单一加密，即它看起来(简化)如下:

Whereas with a HTTPS URL over a "normal" HTTP proxy there is only single encryption, i.e. it looks (simplified) like this:

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.这实际上是最常见的情况.

Very likely the proxy you want to use is a plain HTTP proxy, and not a HTTPS proxy. This is actually the most common case.

发生错误是因为代理无法使用 TLS 但被 TLS 访问.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，并且协议的 https:// 值被视为与 http:// 相同>.

The error happens since the proxy is not able to speak TLS but gets accessed by TLS. The fix is to use http://proxy and not https://proxy as the proxy address. Note that the latter worked in older versions of Python since proxy over HTTPS was not supported and a value of https:// for the protocol was treated the same as http://.
