the main question is for me:
Is google is really sure ?
why so many data are inside your account
After that a says some post upper:
Google redirect for to the URI for humain reading (with an HTTPS server)
It send for exemple: [https://googleassistant.bugsounet.fr/?code=my very secret code&scope=https://www.googleapis.com/auth/assistant-sdk-prototype]
My server read the link and search the part named code= and display the code found.
HTML Code is there:
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="config.css" />
<title>@bugsounet Consent OAuth screen ~ Code Reader</title>
<script type="text/javascript">
function getParameterByName(name) {
url = window.location.href;
name = name.replace(/[[]]/g, "\\$&");
var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)");
var results = regex.exec(url);
if (!results) return null;
if (!results[2]) return '';
return decodeURIComponent(results[2].replace(/\+/g, " "));
}
document.addEventListener("DOMContentLoaded", function(event) {
var code = getParameterByName('code');
var scope = getParameterByName('scope');
var scopeURLs = [
"https://www.googleapis.com/auth/assistant-sdk-prototype",
"https://www.googleapis.com/auth/youtube",
"https://www.googleapis.com/auth/photoslibrary https://www.googleapis.com/auth/photoslibrary.sharing",
"https://www.googleapis.com/auth/photoslibrary.sharing https://www.googleapis.com/auth/photoslibrary"
]
var request= document.getElementById('request')
if (code && scopeURLs.indexOf(scope) > -1) {
request.style.display = "none";
document.getElementById('code').innerHTML= "Your code:<br>" + code;
}
});

After, if you want really the source code, I can create a repo with it
Or… just copy the index file from the source with this command:
wget https://googleassistant.bugsounet.fr/index.html
and edit/view the code of index.html
