Ausführen eines Python-Skripts in WordPress

Sie können popen () verwenden,um Lesen oder Schreibenin ein Python-Skript (diesfunktioniert auchmit jeder anderen Sprache). Wenn Sie Interaktionbenötigen (Variablen übergeben),verwenden Sie proc_open () .

Eineinfaches Beispiel zum Drucken von Hello World! in einem WordPress-Plugin

Erstellen Sie das Plugin und registrieren Sieeinen Shortcode:

  & lt ;?php # - * - Kodierung: utf-8 - * -
/* Plugin Name: Pythoneingebettet */

add_shortcode ('python','embedded_python');

Funktioneingebettet_python ($ Attribute)
{
    $ data=shortcode_atts (
        [
            'file'=> 'hallo.py'
        ],
        $ Attribute
    );

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

    while (!feof ($ handle))
    {
        $ read.=fread ($ handle,2096);
    }}

 pclose ($ handle);

    return $ read;
}}
 

Jetzt können Sie diesen Shortcodeim Post-Editormit [python] oder [pythonfile="filename.py"] verwenden.

Legen Sie die Python-Skripte,die Sie verwendenmöchten,im selben Verzeichnis wie die Plugin-Datei ab. Sie können sie auchin ein Verzeichnis stellen und den Pfadim Shortcode-Handler anpassen.

Erstellen Sienunein komplexes Python-Skript wiefolgt:

 print ("Hallo Welt!")
 

Und dasist alles. Verwenden Sie den Shortcode underhalten Sie diefolgende Ausgabe:

You can use popen() to read or write to a Python script (this works with any other language too). If you need interaction (passing variables) use proc_open().

A simple example to print Hello World! in a WordPress plugin

Create the plugin, register a shortcode:

<?php # -*- coding: utf-8 -*-
/* Plugin Name: Python embedded */

add_shortcode( 'python', 'embed_python' );

function embed_python( $attributes )
{
    $data = shortcode_atts(
        [
            'file' => 'hello.py'
        ],
        $attributes
    );

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

    while ( ! feof( $handle ) )
    {
        $read .= fread( $handle, 2096 );
    }

    pclose( $handle );

    return $read;
}

Now you can use that shortcode in the post editor with [python] or [python file="filename.py"].

Put the Python scripts you want to use into the same directory as the plugin file. You can also put them into a directory and adjust the path in the shortcode handler.

Now create a complex Python script like this:

print("Hello World!")

And that’s all. Use the shortcode, and get this output:

Ich habe das Beispielskript von derersten Antwort anbefolgt,aber keine Ausgabe oder Fehlererhalten.

Ich habe diese Zeilegeändert:

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

dazu:

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

underhielt dann die Meldung "Berechtigung verweigert".

Auf der Konsole habeich

 chmod 777 hello.py
 

hat die Seite aktualisiert und alles hatperfektfunktioniert.

Dies könnte das Problem sein,das Joe obengesehen hat.Ich habenichtgenug Repräsentanten,umeinen Kommentar abzugeben,sorry.Hoffe das hilftjemandem.

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.

Hieristein kleines Skript,das proc_open wie oben angegeben verwendet,umeine einfache Textvariable anein Python-Skript zu senden:

 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
 

Im unteren Bereich wurdeneinige Tests hinzugefügt,umfestzustellen,ob die Python-Datei rwxist. Ich denke,ein besserer Weg,um das argv zu senden,wäre die Verwendung vonfwrite,aberesfunktioniertenichtfürmichnach dieses Tutorial .

Hierist das Python-Skript,dasich verwendet habe. Wiein den obigen Kommentarenerwähnt,kannje nach Server #!/usr/bin/env pythonerforderlich sein.

 #!/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
