python客户端和java服务器之间的通信 [英] Communication between python client and java server

问题描述

我的目标是从python套接字向java套接字发送消息。我确实关注了上面提到的资源。但是我很难让Python客户端与Java服务器通信。主要是因为python中的（行尾）与java中的不同。

My aim is to send a message from python socket to java socket. I did look out on the resource mentioned above. However I am struggling to make the Python client talk to Java server. Mostly because (End of line) in python is different from that in java.

说我从python客户端写：消息1：abcd消息2：efgh消息3：q （退出）

say i write from python client: message 1: abcd message 2: efgh message 3: q (to quit)

在java服务器上：我收到消息1：abcdefghq后跟异常，因为python客户端已经从它的末尾关闭了套接字。

At java server: i receive message 1:abcdefghq followed by exception because the python client had closed the socket from its end.

有没有人可以为java和python之间的一致谈话提出解决方案。

Could anybody please suggest a solution for a consistent talk between java and python.

更新：我忘了添加，我正在研究TCP。

Update: I forgot to add, I am working on TCP.

我的JAVA代码如下:(服务器套接字）

My JAVA code goes like this:(server socket)

String fromclient;

ServerSocket Server = new ServerSocket (5000);

System.out.println ("TCPServer Waiting for client on port 5000");

while(true) 
{
    Socket connected = Server.accept();
    System.out.println( " THE CLIENT"+" "+ connected.getInetAddress() +":"+connected.getPort()+" IS CONNECTED ");

    BufferedReader inFromClient = new BufferedReader(new InputStreamReader (connected.getInputStream()));

    while ( true )
    {
        fromclient = inFromClient.readLine();

        if ( fromclient.equals("q") || fromclient.equals("Q") )
        {
            connected.close();
            break;
        }
        else
        {
            System.out.println( "RECIEVED:" + fromclient );
        } 
    }
}

我的PYTHON代码:(客户端套接字）

My PYTHON code : (Client Socket)

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(("localhost", 5000))

while 1:

    data = raw_input ( "SEND( TYPE q or Q to Quit):" )
    if (data <> 'Q' and data <> 'q'):
        client_socket.send(data)
    else:
        client_socket.send(data)
        client_socket.close()
        break;

OUTPUT ::

OUTPUT::

ON PYTHON CONSOLE （客户）：

ON PYTHON CONSOLE(Client):

发送（Q型或Q退出）：abcd（按ENTER）

SEND( TYPE q or Q to Quit):abcd ( pressing ENTER)

发送（TYPE q或Q to Quit）：efgh（按ENTER键）

SEND( TYPE q or Q to Quit):efgh ( pressing ENTER)

发送（Q型或Q退出）：q（按ENTER键）

SEND( TYPE q or Q to Quit):q ( pressing ENTER)

ON JAVA CONSOLE（服务器）：

ON JAVA CONSOLE(Server):

TCPServer在端口5000上等待客户端

TCPServer Waiting for client on port 5000

客户/127.0.0.1:1335已连接

THE CLIENT /127.0.0.1:1335 IS CONNECTED

已收到：abcdefghq

RECIEVED:abcdefghq

推荐答案

您需要将 \ n 附加到数据结尾...

You need to append \n to end of data...

ie ：

client_socket.send(data + '\n')
