Question

我正在尝试使用artdarek / oauth-4软件包设置facebook登录。重定向只返回一个空白页面，其中包含以下网址：

 https://www.facebook.com/dialog/oauth?type=web_server&client_id=1423706434575595&redirect_uri=http%3A%2F%2Flocalhost%3A8888%2FcontractorSherpa%2Fpublic%2Ffacebook&response_type=code&scope=email+read_friendlists+user_online_presence

我使用的是Laravel 4.2.4

路线：

Route::get('/facebook', 'RegistrationController@loginWithFacebook');

RegistrationController：

Public function loginWithFacebook() {

    $code = Input::get('code');

    // get fb service
    $fb = OAuth::consumer('Facebook');

    //check for valid code
    // if empty provide user data
        if ( !empty($code)){
            $token = $fb->requestAccessToken($code);

            //send a request with it
            $result = json_decode( $fb->request('/me'), true);



        if (!empty($token)) {

            try{
                $user = Sentry::findUserByLogin($result['email']);

                Sentry::login($user, false);

                return Redirect::to('contractors/dashboard');
            }
            catch (Cartalyst\Sentry\Users\UsersNotFoundException $e)
            {
                $user = Sentry::register(array(
                            'activated' => 1,
                            'email' => $result['email'],
                            'password' => $result['password'],
                            'first_name' => $result['firstname'],
                            'last_name' => $result['lastname'],
                    ));
                $group = Sentry::findGroupByName($data['contractor']);
                $user->addGroup($usergroup);

                Sentry::login($user, false);

                return Redirect::to('contractors/dashboard');
            }
        }
    }
    else {
            //get fb authorization
        $url = $fb->getAuthorizationUri();

        // return to facebook login url
        return Redirect::to((string)$url);
    }
}

在我的例子中，$ code为null，因此else语句触发。

我尝试了dd（$ url）并得到了这个回复：

object(OAuth\Common\Http\Uri\Uri)#368 (10) { ["scheme":"OAuth\Common\Http\Uri\Uri":private]=> string(5) "https" ["userInfo":"OAuth\Common\Http\Uri\Uri":private]=> string(0) "" ["rawUserInfo":"OAuth\Common\Http\Uri\Uri":private]=> string(0) "" ["host":"OAuth\Common\Http\Uri\Uri":private]=> string(16) "www.facebook.com" ["port":"OAuth\Common\Http\Uri\Uri":private]=> int(443) ["path":"OAuth\Common\Http\Uri\Uri":private]=> string(13) "/dialog/oauth" ["query":"OAuth\Common\Http\Uri\Uri":private]=> string(193) "type=web_server&client_id=1423706434575595&redirect_uri=http%3A%2F%2Flocalhost%3A8888%2FcontractorSherpa%2Fpublic%2Ffacebook&response_type=code&scope=email+read_friendlists+user_online_presence" ["fragment":"OAuth\Common\Http\Uri\Uri":private]=> string(0) "" ["explicitPortSpecified":"OAuth\Common\Http\Uri\Uri":private]=> bool(false) ["explicitTrailingHostSlash":"OAuth\Common\Http\Uri\Uri":private]=> bool(false) }

虽然我添加了几行代码来说明Sentry auth，但我的代码几乎与artdarek包的自述文件中的示例相同。

如何获取正确的网址？

Answer 1

上面的代码是正确的，除了我需要在

中专门定义路线

$fb = OAuth::consumer('Facebook');

这样就变成了

$fb = OAuth::consumer( 'Facebook', 'http://www.contractorsherpa.com/facebook/' );

您要在该网址中引用的网页是您在路线中发布的网页。不要忘记尾随斜线。在斜杠之后添加$ code，然后触发if语句：

if(!empty($code))

使用artdarek / oauth-4登录Facebook会返回空白
