Question

我正在使用来自Facebook开发者页面的修改示例。我的JS：

window.fbAsyncInit = function() {
    FB.init({
    appId      : '{xxx}',
    cookie     : true,  
    xfbml      : true,  
    version    : 'v2.8' 
});
FB.getLoginStatus(function(response) {
        statusChangeCallback(response);
});
};

  // Load the SDK asynchronously
  (function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_GB/sdk.js#xfbml=1&version=v2.8&appId=xxx";
    fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));

function statusChangeCallback(response) {
    console.log('statusChangeCallback');
    console.log(response);
    if (response.status === 'connected') {
      testAPI();
    } else if (response.status === 'not_authorized') {
      document.getElementById('status').innerHTML = 'Please log ' +
        'into this app.';
    } else {
      document.getElementById('status').innerHTML = 'Please log ' +
        'into Facebook.';
    }
  }

function checkLoginState() {
    FB.getLoginStatus(function(response) {
        statusChangeCallback(response);
    });
}
 function testAPI() {
    console.log('Welcome!  Fetching your information.... ');
        FB.api('/me', {fields: 'id,name,email'}, function(response) {
            console.log('Successful login for: ' + response.name);
            console.log('Here is email: ' + response.email);
            document.getElementById('status').innerHTML ='Thanks for logging in, ' + response.name + '!';
    });
    $.get(baseurl + 'index.php/auth/fb_login', function(response){
        console.log(response);
    });
}

$(document).ready(function(){
    $('body').on('click', '.fb-login', function(){
        FB.login(function(response){
            statusChangeCallback(response);
        }, {scope: 'public_profile,email'});
    });
});

基本思路是，在成功登录后，我在控制台中显示响应对象并运行testAPI()，这将进行API调用并在控制台中显示名称和电子邮件。之后我添加了对auth/fb_login的ajax调用：

function fb_login(){
        require_once( 'vendor/autoload.php' );
        $fb = new Facebook\Facebook([
          'app_id'                => $this->config->item('app_id', 'tank_auth'),
          'app_secret'            => $this->config->item('app_secret', 'tank_auth'),
          'default_graph_version' => $this->config->item('default_graph_version', 'tank_auth')
        ]);

        $helper = $fb->getJavaScriptHelper();
        try {
          $accessToken = $helper->getAccessToken();
        } catch(Facebook\Exceptions\FacebookSDKException $e) {
          echo $e->getMessage();
          exit;
        }

        if ($accessToken) {
          var_dump('Successfully logged in!');die();
        }
        var_dump(' not Successfully logged in!');die();
    }

而var_dump总是转储＆＃34;而不是......＆＃34;没有任何FB例外。

我使用facebook debug tool并返回

Error validating access token: This may be because the user logged out or may be due to a system error.

Application ID  xxx: MyAppName
User ID
xxx: Kārlis Janisels
User last installed this app via API v2.x
Issued  Unknown
Expires 1480410000 (in about an hour)
Valid   False
Origin  Unknown
Scopes  email, public_profile

所以下划线问题 - 我可以在浏览器中获得有效的访问令牌，但不能在服务器中获取。

如果有帮助 - 我在wamp服务器localhost上使用codeigniter框架。

FB访问令牌为空，没有从PHP SDK v5抛出任何FB异常
