PHP套接字客户端未返回完整响应

标签： php python sockets client response

我有一个Python套接字服务器和一个PHP套接字客户端。客户端向服务器发送命令，然后在页面上显示响应。它几乎一直都很完美。现在我的问题是，当涉及到长时间的回应时，反应似乎有所减少。

它不是Python服务器，因为您通过Telnet获得完整的响应。弄清楚，我可以通过PHP脚本来解决这个问题。想知道。

来自Telnet的输出：

我已经搜索了几周并尝试了所有方法，但无法弄清楚问题。

这是所有这些背后的PHP脚本： 

public function send($cmd, $host, $port, $timeout = 1.5){
    // Get time of function start
    $startTime = time();

    //Try to create a socket
    if(!($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)))
    {
        $errorcode = socket_last_error();
        $errormsg = socket_strerror($errorcode);
        //If failed, die with error. (Check docs)
        die("Error (#300)");
    }

    if(!socket_set_nonblock($socket)){
        die("Error (#301)");
    }

    while(!@socket_connect($socket, $host, $port)){
        if ((time() - $startTime) >= $timeout){
            die("Error (#302)");
        }
        continue;
    }

    if(!socket_set_block($socket)){
        die("Error (#303)");
    }

    if(!socket_write($socket, $cmd, strlen($cmd)))
    {
        $errorcode = socket_last_error();
        $errormsg = socket_strerror($errorcode);

        die("Error (#304)");
    }
    $reply = socket_read($socket, 16384)
            or die("Error (#305)");

    socket_close($socket);
    return $reply;
}

如果有人知道如何解决这个问题，请帮帮我 提前谢谢！

您应该测试socket_write()的返回值是否确实发送了与发送的数据一样多的数据，即strlen($cmd)个字节。如果不是这种情况，请将其余部分写入套接字，直到所有数据都被发送出去。

来自socket_write()的文档：

  

socket_write（）不一定要写入给定缓冲区中的所有字节。它是有效的，根据网络缓冲区等，只有一定数量的数据，甚至一个字节，写入虽然你的缓冲区更大。您必须注意，以免无意中忘记传输其余数据。
