Error when granularity="best" in Latitude service

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a script with this content :

<?php

    require_once "../../src/apiClient.php";
    require_once "../../src/contrib/apiLatitudeService.php";

    require_once "includes/header.php";

    $apiClient = new apiClient();
    $lat = new apiLatitudeService($apiClient);

    if (isset($_SESSION['auth_token'])) {
      $apiClient->setAccessToken($_SESSION['auth_token']);
    } else {
      $_SESSION['auth_token'] = $apiClient->authenticate();
    }

    $latitude1 = $lat->getCurrentLocation('city');

    echo "<pre>";
    print_r($latitude1);
    echo "</pre>";

    $latitude2 = $lat->getCurrentLocation('best');

    echo "<pre>";
    print_r($latitude2);
    echo "</pre>";

?>

2. Execute the script and look the result


What is the expected output? What do you see instead?
The result to the line "$latitude1 = $lat->getCurrentLocation('city');" works, 
the position is returned, but
the line "$latitude2 = $lat->getCurrentLocation('best');" return an error :
Fatal error: Uncaught exception 'apiServiceException' with message 'Error

Hello,

I've just tested your script on my localhost with WAMP. My result is that I've 
been redirected to this page :
https://www.google.com/latitude/b/0/apps?latitudeAuthResponse=INVALID_REQUEST_PA
RAMS

Do I have to specify an ApiKey or something ?

My knowledge of this is pretty minimal (I've learned just enough to do what I 
need to do...) but my understanding is you need to authorise the request with 
an OAuth access token. Your code structure differs from mine, but maybe you'll 
get the idea?

if(!$accessToken=unserialize(file_get_contents('/home/lee/latitude/token.txt')))
 die('Unable to read access token.');
$client = $accessToken->getHttpClient($oauthOptions);

My token is stored in a text file, that is then read each time the script runs 
to pull location data.

Is your token authorised to use 'best' ? There are 2 request types, city and 
best. Your token needs to have the right authority.

Now after I'm authorized and redirected back to my site I get the following : 



Fatal error: Uncaught exception 'apiCacheException' with message 'Cache file 
could not be deleted' in

I think comment #4 above is correct.  I have seen a similar error because the 
token was authorized with an improper scope.  

In src/config.php i changed the scope for latitude to .all.best and that fixed 
the error.  Other scopes are likely appropriate for different uses.

It looks like the latitude API deprecated the 
https://www.googleapis.com/auth/latitude scope and replaced it with the 
following scopes:
   https://www.googleapis.com/auth/latitude.all.best
   https://www.googleapis.com/auth/latitude.all.city

I've included these scopes in the latest version of the client library, see 
http://code.google.com/p/google-api-php-client/source/browse/trunk/src/config.ph
p#63

If you want to use granularity="best", you'll need to use the scope 
'https://www.googleapis.com/auth/latitude.all.best'
