套接字程序 Python

Question

我正在制作一个刽子手游戏。我正在尝试向服务器发送如果 loss == 7，则 lossGame = true。而在客户端，如果 lostGame 为真，则打印出游戏已经输掉。我匹配了发送和接收，但它不工作，并不断要求输入猜测字母。你知道我做错了什么吗？

我认为这是问题所在。

谢谢！

在我让它工作之前，我遇到了一些问题： 1.注意输入时使用raw_input，否则对我来说崩溃了。 2.您认为服务器存在问题的地方确实存在问题。您不小心关闭了连接，然后在游戏丢失后发送 3.在客户端你有loseGame = loseGame.encode('utf-8')而不是loseGame = loseGameInBytes.encode('utf-8') 4.我将打印语句更改为print(str(x) + " "),，因为您的问题给了我

这是我修复后的代码。请注意，我在服务器中更改并添加了不必要的中断，它们将导致服务器在单场游戏结束时关闭。

serverSocket = socket(AF_INET, SOCK_STREAM)

serverSocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)

# Start listening on specified port
serverSocket.bind(('', serverPort))

# Listener begins listening
serverSocket.listen(1)

print("The server is ready to receive")

#Set secret word
