Question

当我尝试连接到本地主机时，出现[SSL：WRONG_VERSION_NUMBER]错误。我默认使用“ 8080”端口。以前，我收到了ProxyError，然后将URL从“ http”更改为“ https”，现在得到了SSLError。我已经检查了一些解决方案，提示您更改端口号。它是否需要对端口号进行其他操作？

views.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

Answer 1

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

从您在your previous question中进行的编辑中，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在给定的端口8080上支持HTTP，而在尝试使用的端口上不支持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启动TLS握手，并希望服务器以ServerHello进行回复。服务器仅发送纯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确定TLS协议版本。由于这不是TLS响应，因此将其解释为TLS时，该信息没有意义，这会导致出现这种奇怪的错误消息。

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（您提到了一些ProxyError，但没有详细信息），则需要解决这些问题，而不仅仅是尝试通过HTTPS访问该网站-如您所见，这只会导致其他问题。
