Запуск скрипта Python в wordpress

Я выполнил пример сценария из первого ответа,но не получал никаких результатов или ошибок.

Я изменил эту строку:

 $handle = popen( __DIR__ . '/' . $data['file'], 'r' );
 

к этому:

 $handle = popen( __DIR__ . '/' . $data['file'] . ' 2>&1', 'r' );
 

,а затем получил сообщение "в разрешении отказано".

На консоли я запустил

 chmod 777 hello.py
 

обновил страницу,и все заработало.

Возможно,это проблема,которую Джо видел выше.У меня недостаточно представителей,чтобы оставить комментарий,извините.Надеюсь,это кому-то поможет.

I followed the example script from the first answer, but was getting no output or errors.

I changed this line:

$handle = popen( __DIR__ . '/' . $data['file'], 'r' );

to this:

$handle = popen( __DIR__ . '/' . $data['file'] . ' 2>&1', 'r' );

and then got a "permission denied" message.

On the console, I ran

chmod 777 hello.py

refreshed the page, and everything worked perfectly.

This may be the issue Joe was seeing above. I don't have enough rep to make a comment, sorry. Hope this helps someone.

Вот небольшой скрипт,который использует proc_open,как указано выше,для отправки одной простой текстовой переменной в скриптpython:

 add_shortcode( 'execute_python', 'execute_python_with_argv' );

function execute_python_with_argv( $attributes ){

$description = array (     
    0 => array("pipe", "r"),  // stdin
    1 => array("pipe", "w"),  // stdout
    2 => array("pipe", "w")   // stderr
);

$application_system = "python ";
$application_path .= plugin_dir_path( __FILE__ );
$application_name .= "hello.py";
$separator = " ";

$application = $application_system.$application_path.$application_name.$separator;

$argv1 = '"output to receive back from python script"';
$pipes = array();

$proc = proc_open ( $application.$argv1 , $description , $pipes );

//echo proc_get_status($proc)['pid'];

if (is_resource ( $proc ))
{
    echo "Stdout : " . stream_get_contents ( $pipes [1] ); //Reading stdout buffer
    fclose ( $pipes [1] ); //Closing stdout buffer
    fclose ( $pipes [2] ); //Closing stderr buffer

    $return_value = proc_close($proc);
    echo "<br/>command returned: $return_value<br/>";
}

$application_test = glitch_player_DIR.$application_name;

echo "<br/>Is ".$application_test." executable? ".is_executable($application_test)." ";
echo "readable? ".is_readable($application_test)." ";
echo "writable? ".is_writable($application_test)." ";

} //EOF main/shortcode function
 

Внизу добавлено несколько тестов,чтобы проверить,является ли файлpython rwx. Я думаю,что лучший способ отправить argv - использоватьfwrite,но у меня он не работал после это руководство .

Вот скрипт Python,который я использовал. Как отмечалось в комментариях выше,в зависимости от сервера может потребоваться что-то вроде #!/usr/bin/env python.

 #!/usr/bin/env python

from sys import argv

script, what_he_said = argv

print "This is what you submitted: %s \n \n Isn't that amazing, man? " % what_he_said
 

Here's a little script that uses proc_open as noted above, to sent one simple text variable to a python script:

add_shortcode( 'execute_python', 'execute_python_with_argv' );

function execute_python_with_argv( $attributes ){

$description = array (     
    0 => array("pipe", "r"),  // stdin
    1 => array("pipe", "w"),  // stdout
    2 => array("pipe", "w")   // stderr
);

$application_system = "python ";
$application_path .= plugin_dir_path( __FILE__ );
$application_name .= "hello.py";
$separator = " ";

$application = $application_system.$application_path.$application_name.$separator;

$argv1 = '"output to receive back from python script"';
$pipes = array();

$proc = proc_open ( $application.$argv1 , $description , $pipes );

//echo proc_get_status($proc)['pid'];

if (is_resource ( $proc ))
{
    echo "Stdout : " . stream_get_contents ( $pipes [1] ); //Reading stdout buffer
    fclose ( $pipes [1] ); //Closing stdout buffer
    fclose ( $pipes [2] ); //Closing stderr buffer

    $return_value = proc_close($proc);
    echo "<br/>command returned: $return_value<br/>";
}

$application_test = glitch_player_DIR.$application_name;

echo "<br/>Is ".$application_test." executable? ".is_executable($application_test)." ";
echo "readable? ".is_readable($application_test)." ";
echo "writable? ".is_writable($application_test)." ";

} //EOF main/shortcode function

Added a few tests as the bottom to see if the python file is rwx. I think a better way to send the argv would be using fwrite, but it wasn't working for me following this tutorial.

Here is the python script I used. As noted in comments above, something like #!/usr/bin/env python may be necessary, depending on server.

#!/usr/bin/env python

from sys import argv

script, what_he_said = argv

print "This is what you submitted: %s \n \n Isn't that amazing, man? " % what_he_said
