CakePHP的验证组件使用$这个 - ＆GT当登录不可; Auth-＆GT;登录（）; [英] CakePHP Auth Component Not logging in when using $this->Auth->login();

问题描述

我是新来CakePHP的，我看了他们的文档，我跟随他们简单的身份验证的例子。我还搜查甚广（包括在本网站的答案）的答案，我的问题。

I'm new to cakePHP and I have read their documentation and I'm following their simple authentication example. I've also searched far and wide (including answers on this site) for an answer to my problem.

我使用CakePHP 2.0和我UsersController的登录功能是这样的：

I'm using cakePHP 2.0 and my UsersController's login function looks like this:

function login() {
    if ($this->request->is('post')) {
        if ($this->Auth->login(/*$this->request->data*/)) {
            $this->redirect($this->Auth->redirect());
        }else {
            $this->Session->setFlash(__('Invalid username or password, try again'));
        }
    }
}

我AppController的是这样的：

My AppController looks like this:

public $components = array(
                    'Session',
                    'Auth' => array(
                            'loginRedirect' => array('controller' => 'pages', 'action' => 'display'),
                            'logoutRedirect' => array('controller' => 'pages', 'action' => 'display')
                    )
        );

public function beforeFilter() {
    $this->Auth->loginAction = array('controller' => 'users', 'action' => 'login');
}

我的用户模型：

class User extends AppModel {

public $name = "User";

}

和登录表单：

echo $this->Session->flash('auth');
echo $this->Form->create('User', array('action' => 'login'));
echo $this->Form->input('username');
echo $this->Form->input('password');
echo $this->Form->end('Login');

问题是，它没有登录的用户。当$这个 - > Auth->登录（）被调用，而不$这个 - >请求 - 作为一个参数没有被写在会议上，只是网页>数据refreshes.However当您​​提供它的工作原理$这个 - >请求 - >数据，凭据被写入了会议，我正确地重定向。不过我注意到，你可以'登录'人与$这个 - > Auth->登录（$这个 - >请求 - >数据），即使它们不是在数据库present。除此之外，如果我输错的凭据没有任何反应，则不会显示任何提示信息。

The problem is it doesn't log a user in. When $this->Auth->login() is called without $this->request->data as a parameter nothing is written in the session and the page just refreshes.However when you supply the $this->request->data it works, credentials are written to the session and I'm redirected correctly. However I've noticed that you can 'log in' anyone with $this->Auth->login($this->request->data) even if they are not present in the database. In addition to this, if I enter wrong credentials nothing happens, no flash messages are displayed.

我不想做任何特别的，我要的是在登录用户的能力。我有一个用户名和密码字段一个简​​单的用户表，我也跟着他们的榜样，阅读他们的文档，但仍没有我曾尝试工作过。

I'm not trying to do anything special, all I want is the ability to log a user in. I have a simple users table with username and password fields and I have followed their example and read their documentation, but still nothing I have tried has worked.

我道歉，如果我没有提供需要提供响应的所有信息。任何帮助是极大的AP preciated。

I apologise if I have not supplied all the information needed to provide a response. Any help is greatly appreciated.

推荐答案

我有相同的经历。发生了什么事我的是，在一个点上，我能够成功登录使用一些用户名和密码，但我从来没有在这给我看，我登陆，我也真的很困惑的任何视图code，当我随后登录随机用户名和密码，但它仍然给了我一个成功的登录通知。

I had the exact same experience. What happened to me was, at one point, I was able to log in successfully using some username and password, but I never had any code in the view that showed me I was logged in. I was also really confused that when I subsequently logged in with random usernames and passwords, it still gave me a successful login notification.

我觉得发生了什么事，如果你是在一个登录的状态，那么 $这个 - ＆GT; Auth-＆GT;登录（）将返回真正不管你输入什么用户名和密码。该解决方案可能会以某种方式调用 $这个 - ＆GT; Auth-＆GT;注销（）在你的程序，或清空你的cookies这样程序不指定如被记录在了。然后 $这个 - ＆GT; Auth-方式＆gt;登录（）将工作重新恢复正常。

I think what happened was, if you are in a logged-in state, then $this->Auth->login() will return true no matter what username and password you enter. The solution would probably be to somehow call $this->Auth->logout() in your program, or empty your cookies so that the program doesn't specify you as being logged in anymore. Then $this->Auth->login() will work as normal again.
