Simple form submission redirect to wrong page, why?

Question

I can't understand this behaviour in Google App Script, can someone explain?

This is a very simple script bound to a Sheet. Code:

Code.js

function doGet() {
  return HtmlService.createHtmlOutputFromFile("index.html");
}

function doPost() {
  return HtmlService.createHtmlOutputFromFile("index.html");
}

index.html

<!DOCTYPE html>
<html>
  <head>
    <base target="_top">
  </head>
  <body>
    <form id="form" name="form" action="" method="POST">
      <input type="submit" id="submit" name="submit" value="submit">
    </form>
  </body>
</html>

Looks simple enough right? Well when you click the submit button, the page redirect to a blank page.

I already know how to work around this behavior (by using script.run or even hackier by querying for the page's URL), but what I want is to know WHY things go wrong here, because what's the point of the doPost method if you can't even use it.

Answer 1

This is because your page is served from another url *.googleusercontent.com for security reasons. The point of doPost method is you can post to the published url from your client(say, local Python script/nodeJs) anywhere on any server as long as you know the published url.
