Facebook login issue (php sdk 3.1.1 + latest js SDK)_问答_开发者

I've created test.php
Copied exa开发者_Go百科mple from here
Changed appId, and secret
Uploaded test.php to server
Tried to login

And I get an exception "An active access token must be used to query information about the current user"

Please help me someone with this.. It's already 5 days I can't do anything with this.

I encountered the same problem many times. Try this:

public static $CURL_OPTS = array(
   CURLOPT_CONNECTTIMEOUT => 100,//-----increase this value
   CURLOPT_RETURNTRANSFER => true,
   CURLOPT_TIMEOUT        => 600,//-----increase this value
   CURLOPT_USERAGENT      => 'facebook-php-3.1',

 );

Just to add to the original question, I just copied the code posted by normeus, changed the appID and secret to the values for my application, and got the following:

You are not Connected.
Fatal error: Uncaught OAuthException: Invalid OAuth access token signature. thrown in 
/path/to/my/server/app/address/base_facebook.php on line 1033

Of course in the facebook bar at the top of the screen it shows that I have 1 unread message since I'm actually logged in. Is there some other setting that needs to be made? It seems like there are a lot of people with this issue, but also a lot who don't have it with no definitive solution.

It will be easier if you posted code since this sounds like a typo. you are not logged into Facebook and your page is not asking you to login so you are not getting a token and you get a token error. This works:

<?php

// * Copyright 2011 Facebook, Inc.


require '../inc/src/facebook.php';

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
    'appId'  => 'APP ID NUMBER',
    'secret' => 'APP SECRET CODE',
  'scope'  => 'manage_pages,offline_access,publish_stream'
));

// Get User ID
$user = $facebook->getUser();

// We may or may not have this data based on whether the user is logged in.
//
// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

// Login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl();
}

?>

I've found a solution.

I've added CURLOPT_SSL_VERIFYPEER => 0 to base facebook class.

public static $CURL_OPTS = array(
    CURLOPT_CONNECTTIMEOUT => 10,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_TIMEOUT        => 60,
    CURLOPT_USERAGENT      => 'facebook-php-3.1',
    CURLOPT_SSL_VERIFYPEER => 0
  );
