Java 套接字：为什么来自服务器的消息总是被分成完全相同的两条消息？

此php代码段位于服务器端：

if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) 
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";


//bind the socket to the ip address and port
if (socket_bind($sock, $address, $port) === false) 
    echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";  

//make the socket listen for connections, SOMAXCONN is the max limit of queued sockets waiting to 
//connect
if (socket_listen($sock, SOMAXCONN) === false) 
    echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";

if (($client= socket_accept($sock)) === false) 
    echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";

if ( false === ($id = socket_read($client, 10, PHP_NORMAL_READ)) )
    socket_close( $client ); //close the socket connection

$talkback = "PHP: Your id is '$id'.\n";
socket_write($client, $talkback, strlen($talkback));

while ((inputLine = in.readLine()) != null) 
    Log.i( "MY_TAG", "Message received: " + inputLine);

此java代码段位于客户端：

if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) 
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";


//bind the socket to the ip address and port
if (socket_bind($sock, $address, $port) === false) 
    echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";  

//make the socket listen for connections, SOMAXCONN is the max limit of queued sockets waiting to 
//connect
if (socket_listen($sock, SOMAXCONN) === false) 
    echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";

if (($client= socket_accept($sock)) === false) 
    echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";

if ( false === ($id = socket_read($client, 10, PHP_NORMAL_READ)) )
    socket_close( $client ); //close the socket connection

$talkback = "PHP: Your id is '$id'.\n";
socket_write($client, $talkback, strlen($talkback));

while ((inputLine = in.readLine()) != null) 
    Log.i( "MY_TAG", "Message received: " + inputLine);

其中，

inputLine

是一个字符串，

in

是客户端套接字的输入流

输出总是：

if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) 
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";


//bind the socket to the ip address and port
if (socket_bind($sock, $address, $port) === false) 
    echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";  

//make the socket listen for connections, SOMAXCONN is the max limit of queued sockets waiting to 
//connect
if (socket_listen($sock, SOMAXCONN) === false) 
    echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";

if (($client= socket_accept($sock)) === false) 
    echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";

if ( false === ($id = socket_read($client, 10, PHP_NORMAL_READ)) )
    socket_close( $client ); //close the socket connection

$talkback = "PHP: Your id is '$id'.\n";
socket_write($client, $talkback, strlen($talkback));

while ((inputLine = in.readLine()) != null) 
    Log.i( "MY_TAG", "Message received: " + inputLine);

收到消息：您的id是'1

---

收到消息：'.

您正在从套接字读取

$id

，在

PHP\u NORMAL\u READ

中，读取被换行符终止，因此

$id==“1\n”

。只需

trim（）

it：

$id = trim($id);
//or
$talkback = "PHP: Your id is '" . trim($id) . "'.\n";

---

显示您是如何打开套接字的？

$id=“1\n”

可能吗？@MarcB我已经添加了它。我只包含了我认为你们需要看到的必要代码，但如果你们需要看到更多，请告诉我。我一按照你们的建议完成var_转储就意识到了这一点。非常感谢。
