CakePHP + Facebook [英] CakePHP + Facebook

问题描述

我想实现facebook连接到我的cakephp应用程序。我使用Nick的Facebook插件。

I am trying to implement facebook Connect to my cakephp Application. i am using Nick's Facebook Plugin.

我想用这种方式实现

1. 当用户访问网站时，他应该可以通过网站上的注册或Facebook Connect登录


2. 现有用户应该能够将他们的帐户连接到他们的FB帐户


3. 首次使用FB Connect登录该网站的人员，并且在网站上没有帐户。应重定向到他们必须输入详细信息以完成配置文件的页面。

我做了什么 -
遵循尼克的指令实现它，当我单击登录 - 它连接到我的应用程序。但我不明白如何创建与Fb Connect Id相关联的用户名和密码。

What i have done - I have followed the instruction of Nick to implement it and when i click Login - it connects to my app. but i dont understand how to create a username and password associated with the Fb Connect Id. and user it against the FB token.

推荐答案

显然我正在做相同 事物 a

这里有一个Facebook登录的方法我正在使用（略微编辑和注释）：

Here's a method for Facebook login I'm using (slightly redacted and annotated):

public function facebook($authorize = null) {
    App::import('Lib', 'Facebook.FB');
    $Fb = new FB();

    $session = $Fb->getSession();

    // not logged into Facebook and not a callback either,
    // sending user over to Facebook to log in
    if (!$session && !$authorize) {
        $params = array(
            'req_perms'  => /* the permissions you require */,
            'next'       => Router::url(array('action' => 'facebook', 'authorize'), true),
            'cancel_url' => Router::url(array('action' => 'login'), true)
        );
        $this->redirect($Fb->getLoginUrl($params));
    }

    // user is coming back from Facebook login,
    // assume we have a valid Facebook session
    $userInfo = $Fb->api('/me');

    if (!$userInfo) {
        // nope, login failed or something went wrong, aborting
        $this->Session->setFlash('Facebook login failed');
        $this->redirect(array('action' => 'login'));
    }

    $user = array(
        'User' => array(
            'firstname'       => $userInfo['first_name'],
            'lastname'        => $userInfo['last_name'],
            'username'        => trim(parse_url($userInfo['link'], PHP_URL_PATH), '/'),
            'email'           => $userInfo['email'],
            'email_validated' => $userInfo['verified']
        ),
        'Oauth' => array(
            'provider'        => 'facebook',
            'provider_uid'    => $userInfo['id']
        )
    );

    $this->oauthLogin($user);
}

这给了我一个包含所有用户信息的数组，调用 :: oauthLogin ，它使用给定信息记录用户或要求用户填写缺少的详细信息和/或在数据库中创建新的用户记录。从Facebook API获得的最重要的部分是 $ userInfo ['id'] 和/或电子邮件地址，您可以使用它们来识别您的数据库。如果您使用AuthComponent，可以使用 $ this-> Auth-> login（$ user_id）手动登录用户，其中 $ user_id 是您自己数据库中的用户的ID。

This gives me an array with all the user details I could grab from Facebook and invokes ::oauthLogin, which either logs the user in with the given information or asks the user to fill in missing details and/or creates a new user record in the database. The most important part you get from the Facebook API is the $userInfo['id'] and/or email address, either of which you can use to identify the user in your database. If you're using the AuthComponent, you can "manually" log in the user using $this->Auth->login($user_id), where $user_id is the id of the user in your own database.

private function oauthLogin($data) {
    $this->User->create();

    // do we already know about these credentials?
    $oauth = $this->User->Oauth->find('first', array('conditions' => $data['Oauth']));

    if ($oauth) {
        // yes we do, let's try to log this user in
        if (empty($oauth['User']['id']) || !$this->Auth->login($oauth['User']['id'])) {
            $this->Session->setFlash('Login failed');
        }
        $this->redirect('/');
    }

    // no we don't, let's see if we know this email address already
    if (!empty($data['User']['email'])) {
        $user = $this->User->find('first', array('conditions' => array('email' => $data['User']['email'])));
        if ($user) {
            // yes we do! let's store all data in the session
            // and ask the user to associate his accounts

            $data['User'] = array_merge($data['User'], $user['User']);
            $data['Oauth']['user_id'] = $user['User']['id'];

            $this->Session->write('Oauth.associate_accounts', $data);
            $this->redirect(array('action' => 'oauth_associate_accounts'));
        }
    }

    // no, this is a new user, let's ask him to register        
    $this->Session->write('Oauth.register', $data);
    $this->redirect(array('action' => 'oauth_register'));
}
