Question

SSLサーバー/クライアントがオンラインであることがわかりましたが、動作していないようです。私は、鍵と証明書の両方を生成しますが、私は次のエラーを取得：

あなたはtry: ... except...の内側self.ssl_sockを定義し、これは失敗し、そのためself.ssl_sock存在しません。次へ

変更：私のために

try: 
    self.ssl_sock = ssl.wrap_socket(self.soc, 
            ca_certs=ssl_certfile, 
            cert_reqs=ssl.CERT_REQUIRED) 
    print("Wrapped client socket for SSL") 

    try: 
     self.ssl_sock.connect((host, port)) 
     print("client socket connected\n") 

     print("send message") 
     self.ssl_sock.sendall("Twas brillig and the slithy toves") 

    except socket.error as msg: 
     self.printErr("Socket connection error in client: ") 

    finally: 
     self.ssl_sock.close() 

except socket.error as j: 
    print(j, '<---------') 
    print("SSL socket wrapping failed") 

self.soc.close() 
print("exit client")
