有几种方法可以实现这一点。您可以使用Apache模块，如mod_python或mod_wsgi（遵守wsgi python标准），您可以使用cgi脚本，也可以使用PHP（在Web环境中相当常见）通过exec或system函数执行python脚本。 / p>

我认为最简单的就是使用PHP。

  exec （'python /path/to/file.py'）; 
 

编辑：我刚刚意识到我的解决方案只介绍如何运行python脚本。

您可以通过python参数传递url输入。

  $ url = $ _GET [ 'URL']; 
 exec（python /path/to/file.py $ url）; 
 

即使通过用户输入验证，这也是潜在的危险。

要通过按钮执行它，您可以执行AJAX调用。 （jQuery示例）

$ p $ $（'＃button'）。on（'click'，function（）{
$ .get（'python.php'，{url：'url'}）;
}）;


I have a Python script a.py that prompts for a URL:

url = input('URL: ')

It uses modules to check headers for URL validity, takes the valid URL and downloads the first image from the webpage (URL) using Beautiful Soup. It works perfectly as a standalone Python script that I can run in my terminal/command prompt.

What I'd like to build is a webpage that utilizes my Python script and allows users to enter a URL form a web interface. Example:

<input type="text" name="url" />
<button>Download</button>

The URL entered from the input would then be passed into the python script when the user clicks on the Download button.

There are a couple of ways to achieve this. You could use Apache modules like mod_python or mod_wsgi (which adheres to wsgi python standard), you could use a cgi script or you can use PHP (which is fairly common in web environments) to execute the python script through exec or system function.

I think the easiest one would be just use PHP.

exec('python /path/to/file.py');

Edit: I just realized that my solution only describes how to run the python script.

You could pass the url input through an argument on python.

$url = $_GET['url'];
exec("python /path/to/file.py $url");

This is potentially dangerous even with user input validation.

To execute it through a button, you could do an AJAX call. (jQuery example)

$('#button').on('click', function() {
  $.get('python.php', {url : 'url' });
});
