Android套接字没有从php服务器接收数据

我有一个android客户端从php服务器接收数据的问题。 Android可以成功地将数据写入php服务器,服务器接受该数据,然后将响应发送回该客户端,但android不接受。它不会从Socket s = ss.accept()

向前移动

这是我的Android代码来接收数据

public void run() {
    Boolean end = false;
    ServerSocket ss = serverSocket;

    /*try {
        ss = new ServerSocket(54546);
    } catch (IOException e1) {
        //TODO Auto-generated catch block
        e1.printStackTrace();
    }*/
    while(!end){
        //Server is waiting for client here, if needed
        try {
            Log.i("before accept", "yes");
            Socket s = ss.accept();

            BufferedReader input = new BufferedReader(new InputStreamReader(s.getInputStream()));
            //PrintWriter output = new PrintWriter(s.getOutputStream(),true); //Autoflush
            String st = input.readLine();
            Log.d("Tcp Example", "From client: "+st);
            //output.println("Good bye and thanks for all the fish :)");
        }catch (IOException e) {
            e.printStackTrace();
        }
    }
}

这是我的PHP代码

$host = "127.0.0.1";
$port = 54546;
set_time_limit(0);
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
//$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) or die("Could not create socket\n");
/*if (!socket_connect($socket, $host, $port)) {
    die('failed'.socket_strerror(socket_last_error($socket)));
}*/
if (!socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1)) { 
    echo socket_strerror(socket_last_error($socket)); 
    exit; 
}
$result = socket_bind($socket, $host, $port) or die("Could not create socket\n");
$result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
echo "\nbefore socket accept while loop\n";
$aaa = fopen("tesst.txt", "w");

while(true)
{
    echo "\nbefore socket accept\n";
    $spawn = socket_accept($socket) or die("Could not accept incoming connection\n");

    echo "\nThe server is ready\n";
    $input = socket_read($spawn, 1024) or die("Could not read input\n");
    echo "Input recieved from $spawn : ".$input;
    fwrite($aaa, $input);
    $output = $input."\n";

    $sent = socket_write($spawn, $output, strlen ($output)) or die("Could not write output\n");
    echo "Output sent ".$sent;
    socket_close($spawn);
}   
fclose($aaa);
socket_close($socket);
echo "\nTerminating\n";

ss.accept()不接受来自服务器的连接。

我们也不必为客户端做ss.accept()。客户端应使用connect()建立连接,服务器应该执行accept()。建立连接后,服务器应使用accept()返回的文件描述符向客户端发送数据或从客户端接收数据。另一方面,客户端不需要进行任何接受,只需调用recv()来检索接收的数据。

因此,如果Android代码是客户端,那么它应该对PHP服务器执行connect()调用 - connect()调用将获取IP地址和端口号(54546)。通过成功的connect()调用,PHP上的accept()将返回。
