Question

Hello I’m trying to validate the token I’ve created with the accountManager from my php server but I keep getting the error “invalid token” from google server on my php server… Here is the code :

private String updateToken(boolean invalidateToken, int accountref) {
    String authToken = "null";
    try {
        AccountManager am = AccountManager.get(TestAuthActivity.this);
        Account[] accounts = am.getAccountsByType("com.google");
        AccountManagerFuture<Bundle> accountManagerFuture;
        if(TestAuthActivity.this == null){//this is used when calling from an interval thread
            accountManagerFuture = am.getAuthToken(accounts[accountref], SCOPE, false, null, null);
        } else {
            accountManagerFuture = am.getAuthToken(accounts[accountref], SCOPE, null, TestAuthActivity.this, null, null);
        }
        Bundle authTokenBundle = accountManagerFuture.getResult();
        authToken = authTokenBundle.getString(AccountManager.KEY_AUTHTOKEN).toString();
        if(invalidateToken) {
            am.invalidateAuthToken("com.google", authToken);
            authToken = updateToken(false, accountref);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    Dialog d = new Dialog(TestAuthActivity.this);
    d.setTitle("Token :" + authToken);
    d.show();

    createSession(TestAuthActivity.this, authToken);

    return authToken;
}

So I’m getting a token then I’m sending it to my php server :

<?php

if( isset($_POST['authToken'])){        

    //pour que la réponse s'affiche comme du texte brut
    header('Content-Type: text/plain');

    /*partie à modifier*/
    $name = 'www.google.com';//nom du site

    $data = $_POST['authToken'];

    $envoi  = "POST /m8/feeds/contacts/default/full HTTP/1.1\r\n";
    $envoi .= "Host: ".$name."\r\n";
    $envoi .= "Authorization: GoogleLogin auth='".$data."'\r\n";
    $envoi .= "Connection: Close\r\n";
    $envoi .= "Content-type: application/x-www-form-urlencoded\r\n";
    $envoi .= "Content-Length: ".strlen($data)."\r\n\r\n";
    $envoi .= $data."\r\n";

    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    if($socket < 0){
            die('FATAL ERROR: socket_create() : " '.socket_strerror($socket).' "');
    }

    if (socket_connect($socket,gethostbyname($name),80) < 0){
            die('FATAL ERROR: socket_connect()');
    }

    if(($int = socket_write($socket, $envoi, strlen($envoi))) === false){
            die('FATAL ERROR: socket_write() failed, '.$int.' characters written');
    }

    $reception = '';
    while($buff = socket_read($socket, 2000)){
       $reception.=$buff;
    }
    echo(json_encode($reception));

    socket_close($socket);  
}
?>

and I keep getting the error : 401 invalid token :S

Does anyone have a solution or a good sample (couldn’t found one that matches what I want to do !)

Answer 1

I can think of two possible problems you might have:

1. The auth token has expired. When you call your method updateToken() to get the token you need to set the parameter invalidateToken to true to make sure you get a fresh token.
2. The value of SCOPE is wrong. Based on the code you’ve provided it looks like you are trying to use the Google Contacts API, for this API SCOPE should have the value https://www.google.com/m8/feeds
