PHP套接字客戶端沒有返回完整響應

Question

我有一個Python套接字服務器和一個PHP套接字客戶端。客戶端向服務器發送命令，然後在頁面上顯示響應。它幾乎可以一直運行。現在我遇到的問題是，當涉及到長時間的迴應時，迴應似乎被削減了。

它不是Python服務器，因爲您通過Telnet獲得完整響應。這是PHP腳本的東西，我不能爲我的生活，搞清楚。從遠程登錄

我搜索周圍的幾個星期和嘗試了一切，但找不出解決問題。

下面是這一切背後的PHP腳本：

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決這個問題，請幫助我。
在此先感謝！

Answer 1

您應該測試socket_write()的返回值是否發送的數據量與發送的數據量相同，即strlen($cmd)字節。如果不是這種情況，則將其餘的寫入套接字，直到發送完所有數據爲止。

從socket_write()的文檔：

socket_write（）不一定寫從給定的緩衝器中的所有字節。根據網絡緩衝區等的不同，只有一定數量的數據（即使是一個字節）被寫入，儘管緩衝區更大，這是有效的。你必須小心，這樣你纔不會無意中忘記傳輸其餘的數據。
