PHP：SSH連接和python腳本執行

Question

我有我的前端有一個按鈕，這個按鈕說話後端。 後端開始遠程腳本：

<?php 
$myfile = fopen("newfile.txt", "w") or die("Unable to open file!"); 
$connection = ssh2_connect('192.168.56.180', 22); 
ssh2_auth_password($connection, 'root', 'password'); 
$stream = ssh2_exec($connection, 'python /WATSON/APP/test/testlistrbk.py'); 
stream_set_blocking($stream, true); 
$stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO); 
echo $stream_out_contente; 
fwrite($myfile, $stream_out); 
fclose($myfile); 
?> 

我有2個問題，首先一個，PHP應等待的python腳本來完成，因爲它說here但事實並非如此。

第二個，它給了我下面的：

PHP的警告：FWRITE（）預計參數2爲字符串，資源上線41 /var/www/html/WEBAPP/wa_start.php給出

使用stream_get_contents(stream_out);

在你的代碼$stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);這將返回resource不串輸出。試試這個代碼。 `的後續代碼var_dump（$ stream_out）

$myfile = fopen("newfile.txt", "w") or die("Unable to open file!"); 

$connection = ssh2_connect('192.168.56.180', 22); 
ssh2_auth_password($connection, 'root', 'password'); 
$stream = ssh2_exec($connection, 'python /WATSON/APP/test/testlistrbk.py'); 

stream_set_blocking($stream, true); 

$outputStream = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO); 
$errorStream = ssh2_fetch_stream($stream, SSH2_STREAM_STDERR); 

echo "Output: " . stream_get_contents($outputStream); 
echo "Error: " . stream_get_contents($errorStream); 

fwrite($myfile, $outputStream.$errorStream); 
fclose($myfile);
