让Facebook PHP SDK在我的应用程序上运行的问题

Question

I was making a facebook application in which i have to show news feeds of the user who is using it. I am using graph API to do this. The problem is that its not getting me feeds. I used it to show friends like this:

$friends = $facebook->api('/me/friends');

and it is working fine.

For news feeds i use this:

$feeds   = $facebook->api('/me/home');

it shows me an error:

Fatal error: Uncaught IDInvalidException: Invalid id: 0 thrown in 
/home/content/58/6774358/html/test/src/facebook.php on line 560

when i try to get Profile feed (Wall) by using this:

$feeds   = $facebook->api('/me/feed');

it shows me an empty array.

These API calls are showing me results in the graph API page but don't know why not working in my application.Can any one help me please.. My full code is as follows

require_once 'src/facebook.php';

// Create our Application instance. $facebook = new Facebook(array( 'appId' => 'xxxxx', 'secret' => 'xxxxx', 'cookie' => true, ));

$session = $facebook->getSession();
    $fbme = null;
// Session based graph API call.
if (!empty($session)){
    $fbme = $facebook->api('/me');
}
if ($fbme) {
     $logoutUrl = $facebook->getLogoutUrl();
     echo '<a href="'.$logoutUrl.'">Logout</a>';
}else{
    $loginUrl = $facebook->getLoginUrl();
     echo '<a href="'.$loginUrl.'">Logout</a>';
}
$friends = $facebook->api('/me/friends?access_token='.$session["access_token"]);
$feeds   = $facebook->api('/me/feed?access_token='.$session["access_token"]); 
print('<pre>Herere:');print_r($feeds);die;

Did you ask for the read_stream permission during authentication?

What type of Authentication / "Allow" process did you go through?

JavaScript SDK? Facebook PHP SDK? XFBML Login Button?

EDIT- Here are helpful link that will get you started up:

Facebook PHP SDK

Authentication Process

Building Apps on Facebook.com

These are all official docs in Facebook and github.

EDIT: Follow this step by step:

From your original code, look for:

$loginUrl = $facebook->getLoginUrl();

Change it to:

$loginUrl = $facebook->getLoginUrl(array('req_perms'=>'read_stream'));

Uninstall your application first from your account:

http://www.facebook.com/settings/?tab=applications

Then try it again to show new Allow pop-up

EDIT:

It's also about the arrangement of code in the if statements. Use this code:

<?php
require_once 'src/facebook.php';
$session = $facebook->getSession();
$fbme = null;

if($session){
    $fbme = $facebook->api('/me');
    $friends = $facebook->api('/me/friends');
    $feeds = $facebook->api('/me/feed'); 
    $logoutUrl = $facebook->getLogoutUrl();
    echo '<a href="'.$logoutUrl.'">Logout</a>';
    echo "<pre>".print_r($feeds,TRUE)."</pre>";
}else{
    $loginUrl = $facebook->getLoginUrl(array('req_perms'=>'read_stream','canvas'=>1,'fbconnect'=>0));
    echo '<script> top.location.href="'.$loginUrl.'"; </script>>';
}

Uninstall your app again from

http://www.facebook.com/settings/?tab=applications

and re-open the application
