Is there any way of executing a Python script from a web browser? [on hold]

Question

I have a python script which I want to execute when someone clicks on a button in an HTML/PHP web page in the browser. How can this be achieved and what is the best way of doing it?

Answer 1

You need to use flask server for this requirement as browser can not access local file.

By using flask, You need to write Ajax call in .js .

Sample Ajax call.

$(document).ready(function () {
  $('#<ButtonID>').click(function (event) {
    $.ajax({
      url: '/<Flask URL>',
      type: 'POST',
      success: function (data) {
        <DATA OBJECT>
      },
    });
    event.preventDefault();
  });
});

Sample Flask function

@app.route('/<Flask URL>',methods=['POST'])
def result():
    try:
        <DO>
    except:
        logger.error()
        raise
    return jsonify({'data':<Python variable>})

You might need to import necessary modules.

Answer 2

Look at exec https://www.php.net/manual/en/function.exec.php function if you're going to use pure PHP for this.

Answer 3

Flask and Django are two examples of Python based web frameworks which use Jinja . They will both allow for calling a backend script, and passing the results into variables held within the web page code.

Answer 4

With exec ,

$command = "python script_path";
exec($command,$output,$return_var);
if ($return_var) {
    $error = error_get_last();
    var_dump($error)
}

Answer 5

You can use Skulpt library in your website to achieve your goal. Here is the link: http://skulpt.org/using.html

Answer 6

I am not sure if it fits into your needs, but have a look at this:
PyPy.Js

It is an Python interpreter written in JavaScript. Maybe you can do something with it.

Another option is to create an HTTP endpoint with for example Flask and let the button send a request to this endpoint which then executes the file.

Good luck!
