python - Python-Django [SSL: WRONG_VERSION_NUMBER] 错误

问题描述

当我尝试连接到我的本地主机时，我收到 [SSL: WRONG_VERSION_NUMBER] 错误。我默认使用“8080”端口。以前，我收到了 ProxyError，然后我将我的 url 从“http”更改为“https”，现在我收到了 SSLError。我检查了一些解决方案，提示更改端口号。它是否与端口号或其他任何事情有关？

视图.py：

endpoint = 'https://****:8080/MyApp/services/DBConnection/callLoginProcedure'

def index(request):
    post = request.POST
    if request.POST.get('login_button'):
        qd = QueryDict(mutable=True)
        qd.update(
            inputPhoneNumber=request.POST.get('phone_num'),
            inputPassword=request.POST.get('password')
        )
        response = requests.post('{}?{}'.format(endpoint, qd.urlencode()), verify=False)
        result = response.json()
        messages.info(request, result)

    return render(request, 'login/index.html')

错误如下

解决方案

endpoint = 'https://****:8080/MyApp/services/DBConnection/callLoginProcedure'

从您在上一个问题中的编辑中，可以检索到原始 URL。尝试此操作时，很明显您尝试访问的端点仅支持给定端口 8080 上的 HTTP，而不支持您尝试使用的 HTTPS。

[SSL：WRONG_VERSION_NUMBER] 错误

您看到的错误源于尝试使用只能执行 HTTP 的 HTTPS 访问站点。您的客户端通过发送 ClientHello 来启动 TLS 握手，并期望服务器回复 ServerHello。只是，服务器发送一个纯 HTTP 响应。然后，客户端尝试将此响应解释为 TLS ServerHello，其中包括从响应中特定位置的某些字节中找出 TLS 协议版本。由于这不是 TLS 响应，因此当解释为 TLS 时，这些信息毫无意义，这会导致这个奇怪的错误消息。

正确的方法是通过 HTTP 而不是 HTTPS 访问 URL。如果您在那里遇到问题（您提到一些没有详细信息的 ProxyError），那么您需要解决这些问题，而不仅仅是尝试通过 HTTPS 访问该站点 - 正如您所看到的那样只会导致其他问题。
