Python-Django [SSL：WRONG_VERSION_NUMBER]錯誤

Question

在嘗試連接到本地主機時，出現[SSL：WRONG_VERSION_NUMBER]錯誤。 我默認使用“ 8080”端口。 以前，我收到了ProxyError，然后將URL從“ http”更改為“ https”，現在得到了SSLError。 我已經檢查了一些解決方案，提示您更改端口號。 它與端口號有關系嗎？

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')

錯誤如下

Answer 1

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

從上一個問題的編輯中，可以檢索原始URL。 嘗試此操作時，很明顯，您嘗試訪問的端點僅在給定的端口8080上支持HTTP，而在嘗試使用的端口上不支持HTTPS。

[SSL：WRONG_VERSION_NUMBER]錯誤

您看到的錯誤是由於嘗試使用只能執行HTTP的HTTPS訪問站點而引起的。 您的客戶端通過發送ClientHello啟動TLS握手，並希望服務器以ServerHello進行回復。 服務器僅發送純HTTP響應。 然后，客戶端嘗試將此響應解釋為TLS ServerHello，其中包括從響應中特定位置的某些字節中確定TLS協議版本。 由於這不是TLS響應，因此將其解釋為TLS時，該信息沒有意義，這會導致出現此奇怪的錯誤消息。

正確的方法是通過HTTP而不是HTTPS訪問URL。 如果在那里遇到問題（您提到了一些ProxyError，但沒有詳細信息），那么您需要解決這些問題，而不僅僅是嘗試通過HTTPS訪問該網站-如您所見，這只會導致其他問題。
