在wordpress中运行python脚本

我为个人博客安装了WordPress,并且逐步将我多年来写的所有小网页内容移植到博客页面上.

这样的页面是 http://www.projecttoomanycooks.co. uk/cgi-bin/memory/majorAnalysis.py 是一个简单的python脚本,可返回单词列表-我想将这种行为嵌入到wordpress页面中-有人可以为我指出正确的方向在wordpress中运行python点的简单方法?

编辑-在下面的精彩回答之后,我得到了很多建议...但是不幸的是,我还没有...

我有在服务器上执行的python ...

 projecttoomanycooks server [~/public_html/joereddington/wp-content/plugins]#./hello.py 
Hello World!

,它与已激活的插件在同一目录中.

python代码...,其中包含以下代码...

 #!/usr/bin/python
print("Hello World!")

php:

 <?php
/**
 * Plugin Name: Joe's python thing.
 * Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
 * Description: A brief description of the Plugin.
 * Version: The Plugin's Version Number, e.g.: 1.0
 * Author: Name Of The Plugin Author
 * Author URI: http://URI_Of_The_Plugin_Author
 * License: A "Slug" license name e.g. GPL2
 */
/*from http://wordpress.stackexchange.com/questions/120259/running-a-python-scri
pt-within-wordpress/120261?noredirect=1#120261  */
add_shortcode( 'python', 'embed_python' );

function embed_python( $attributes )
{
    $data = shortcode_atts(
        array(
            'file' => 'hello.py'
        ),
        $attributes
    );
    $handle = popen( __DIR__ . '/' . $data['file'], 'r');
    $read   = fread($handle, 2096);
    pclose($handle);

    return $read;
}

I have a WordPress install for a personal blog and I'm gradually porting all of the little web bits I have written over the years to pages on the blog.

One such page is http://www.projecttoomanycooks.co.uk/cgi-bin/memory/majorAnalysis.py which is a simple python script that returns a list of words - I'd like to embedd that behavior within a wordpress page - could someone point me in the right direction for the easyist way of running a spot of python within wordpress?

EDIT - following the wonderful answer below, I have got a lot futher... but unfortunately still not quite there...

I have python that executes on server...

projecttoomanycooks server [~/public_html/joereddington/wp-content/plugins]#./hello.py 
Hello World!

and it's in the same directory as the activated plugin...

The python code... which has the following code...

#!/usr/bin/python
print("Hello World!")

The php:

<?php
/**
 * Plugin Name: Joe's python thing.
 * Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
 * Description: A brief description of the Plugin.
 * Version: The Plugin's Version Number, e.g.: 1.0
 * Author: Name Of The Plugin Author
 * Author URI: http://URI_Of_The_Plugin_Author
 * License: A "Slug" license name e.g. GPL2

/*from http://wordpress.stackexchange.com/questions/120259/running-a-python-scri
pt-within-wordpress/120261?noredirect=1#120261  */
add_shortcode( 'python', 'embed_python' );

function embed_python( $attributes )
{
    $data = shortcode_atts(
        array(
            'file' => 'hello.py'
        ),
        $attributes
    );
    $handle = popen( __DIR__ . '/' . $data['file'], 'r');
    $read   = fread($handle, 2096);
    pclose($handle);

    return $read;
}

- 如果这是一个非常简单的脚本,我想我会用PHP作为WordPress插件/模板重写它；-)但是在某些情况下,人们使用iframe嵌入外部页面.
  
  If it's a very simple script, I think I would just rewrite it in PHP as a WordPress plugin/template ;-) But in some cases people use iframes to embed external pages.

我遵循第一个答案中的示例脚本,但是没有输出或错误.

我更改了这一行:

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

对此:

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

,然后收到"权限被拒绝"消息.

在控制台上,我运行

chmod 777 hello.py

刷新页面,一切正常.

这可能是乔在上面看到的问题.对不起,我没有足够的代表发表评论.希望这对某人有帮助.
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.
- 不要设置权限777.只需使其成为可执行文件即可.chmod + xfilename.py将起作用
  
  Do not make the permission 777. Just make it executale. `chmod +x filename.py` will do

下面是一个小脚本,它如上所述使用proc_open将一个简单的文本变量发送到python脚本:

 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

在底部添加了一些测试,以查看python文件是否为rwx.我认为发送argv的一种更好的方法是使用fwrite,但是在本教程.

这是我使用的python脚本.如上所述,根据服务器,可能需要#!/usr/bin/env python之类的东西.

 #!/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

您可以使用 popen() 来阅读或写入Python脚本(这也适用于任何其他语言).如果您需要交互(传递变量),请使用 proc_open() .

在WordPress插件中打印 Hello World！的简单示例

创建插件,注册简码:

 <?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;
}

现在,您可以在帖子编辑器中将该短代码与[python]或[python file="filename.py"]一起使用.

将要使用的Python脚本放入与插件文件相同的目录中.您还可以将它们放入目录中,并在简码处理程序中调整路径.

现在创建一个像这样的复杂Python脚本:

 print("Hello World!")

仅此而已.使用简码,并获得以下输出:

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:

正确答案忽略了python脚本的第一行,至少就我而言,至少需要是#！/usr/bin/envpython

Correct answer omits that first line of the the python script, at least in my case, needs to be #!/usr/bin/env python

@MikeiLL这取决于用户的系统,因此我故意将其省略.

@MikeiLL That depends on the user’s system, so I left it out deliberately.

基本上是一个安全漏洞.如果您可以通过管道传输到python,也可以通过管道传输到任何其他进程,这可以用于升级更多琐碎的漏洞利用.

basically making a security hole. If you can pipe to python, you can pipe to any other process as well and this can be used to escalate any more trivial exploit.

@MarkKaplun是的,这不是一个好主意.要做到这一点,必须要进行命令转义,然后进行JavaScript + PHP转义.除非有非常特定的理由,否则这不是在WordPress中开发任何内容的好方法."您的科学家-程序员非常关注是否可以,他们没有停下来思考是否应该这样做."

@MarkKaplun yes, this is not a good idea. To do this "right" there will have to be command escaping going in, and JavaScript+PHP escaping going on. This is not a good way to develop anything inside WordPress, unless there is a VERY specific reason to do this. "Your -scientists- programmers were so preoccupied with whether or not they could, they didn’t stop to think if they should."
