app inventor 2 POST

Question

I want to integrate a webviewer component in an appinventor app.

I want the app to POST something to already prepared PHP script. I do not want to use GET. So PHP on server looks like:

<?php echo $_POST['value']; ?>

My appinventor block looks like:

This is NOT working. Any help appreciated. Thanks.

EDIT: 2nd try. Thank you @YiWei.

Solution 1

add requestheaders:content-type:application/x-www-form-urlencoded and buildrequestData

Solution 2

the webviewer only can do GET
this should work:

using the web component, you get the result back in the Web.GotText event
