Qt的版本： 5.8.0Qt的C++ SSL/TLS服務器與Python客戶端
Python版本： 2.7.13
OpenSSL的版本：的OpenSSL 1.0.1c
操作系統： Windows 10
我正在嘗試創建一個SSL/TLS服務器usin g Qt C++和用Python編寫的客戶端。我正在使用Qt附帶的示例項目sslechoserver。對於Python客戶端的示例，我使用的是我從此Python文檔獲得的一個：https://docs.python.org/2/library/ssl.html。我複製了上述服務器示例中的證書，並將其放在Python腳本旁邊，並指定在我嘗試的測試腳本中。
我也曾經嘗試過各種Python客戶端的例子我已經在互聯網上找到（像這裏：https://carlo-hamalainen.net/blog/2013/1/24/python-ssl-socket-echo-test-with-self-signed-certificate），但沒有一個能夠完全連接到Qt的回聲服務器（它從來沒有打印出來客戶端連接：像它當我使用Qt附帶的示例時）。上面鏈接中的客戶端可以使用來自同一鏈接的Python服務器，所以我知道它仍然適用於某些東西。
