PHP：SSH连接和python脚本执行

Question

我有我的前端有一个按钮，这个按钮说话后端。 后端开始远程脚本：

<?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个问题，首先一个，PHP应等待的python脚本来完成，因为它说here但事实并非如此。

第二个，它给了我下面的：

PHP的警告：FWRITE（）预计参数2为字符串，资源上线41 /var/www/html/WEBAPP/wa_start.php给出

使用stream_get_contents(stream_out);

在你的代码$stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);这将返回resource不串输出。试试这个代码。 `的后续代码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);
