Eseguire uno script python all'interno di wordpress

Ho seguito lo script diesempio dallaprima risposta,manon ho ricevuto alcun output oerrori.

Ho cambiato questa riga:

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

a questo:

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

e poi ha ricevuto unmessaggio di "autorizzazionenegata".

Sulla console,hoeseguito

 chmod 777 hello.py
 

ha aggiornato lapaginae tutto hafunzionatoperfettamente.

Questopotrebbeessereilproblema che Joe stava riscontrando sopra.Non ho abbastanza rappresentanteperfare un commento,mi dispiace.Spero che questo aiuti qualcuno.

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.

Ecco unpiccolo script che utilizza proc_open comeindicato sopra,perinviare una semplice variabile ditesto a uno script Python:

 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
 

Aggiunti alcunitestin fondoper vedere seilfilepython è rwx. Penso che unmodomiglioreperinviare argv sarebbe usarefwrite,manon hafunzionatoperme seguendo questotutorial .

Ecco lo scriptpython che ho usato. Comenotatonei commenti sopra,potrebbeesserenecessario qualcosa come #!/usr/bin/env python,a seconda del 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
 

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
