将 Java 服务器与 Python 客户端连接

Question

事情是这样的，我有一个基本的 java 服务器，可以将它从它接收到的内容发回给客户端。客户端写在python。我能够建立第一个连接，因为服务器会向客户端发送一条确认连接的消息。但是当我想让客户端发送服务器时，什么都不做。不知道是客户端没有发送问题还是服务器没有接收问题

这是服务器的代码：

    int portNumber = Integer.parseInt(args[0]);

    try ( 
        ServerSocket serverSocket = new ServerSocket(portNumber);
        Socket clientSocket = serverSocket.accept();
        PrintWriter outs =
            new PrintWriter(clientSocket.getOutputStream(), true);
        BufferedReader in = new BufferedReader(
            new InputStreamReader(clientSocket.getInputStream()));
    ) {

        String inputLine, outputLine;


        outputLine = "Hello socket, I'm server";
        outs.println(outputLine);
        outs.println("I' connected");
        while ((inputLine = in.readLine()) != null) {
             outputLine = inputLine;
            outs.println(outputLine);
            if (outputLine.equals("Bye."))
                break;

        }

    } catch (IOException e) {
        System.out.println("Exception caught when trying to listen on port "
            + portNumber + " or listening for a connection");
        System.out.println(e.getMessage());
    }
}  }

这是客户：

import socket

HOST = "localhost"
PORT = 8080

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((HOST, PORT))
print (socket.getaddrinfo(HOST,PORT))
buffer_size = 100

while True :  
    data = sock.recv(buffer_size)     
    print ('you recieved :' , data)
    test = input('send here\n')     
    sock.sendall(bytes(test, 'utf-8'))
    print ('you sent : ' , test)

在 Python 客户端中：您的提示包含 \n 但输入的结果没有？尝试在发送前将 \n 添加到 test。
