是否可以模拟 CakePHP 测试（PHP 单元）的方法的变量值？

Question

我正在测试我的 API，并且有一个用于 OAuth 的登录方法，我似乎无法正确测试它，因为它在 POST 时不会读取变量的 $_GET 值。

登录方式。基本上 $OAuthParams 在使用 POST 时不会被设置，因为 getAuthorizeParams() 使用 $_GET。 所以我想填充/模拟 $_GET 或 $OAuthParams。

public function login () {
    $OAuthParams = $this->OAuth->getAuthorizeParams();
    if ($this->request->is('post')) {
        $this->validateRequest();
        $loginData = array('User' => array(
                'username' => $this->request->data['User']['username'],
                'passwd' => $this->request->data['User']['passwd']
            ));
        //Attempted login
        if ($this->Auth->login($loginData['User'])) {
            unset($loginData);
            $userData = $this->User->find('first',array(
                'conditions' => array(
                    'User.username' => $this->request->data['User']['username']
                ),
                'fields' => array('username','name','id','banned','active','role','private'),
                'recursive' => -1
            ));

            $this->Session->write('Auth.User',$userData['User']); //Update the session

            //Write this to session so we can log them out after authenticating
            $this->Session->write('OAuth.logout', true);

            //Write the auth params to the session for later
            $this->Session->write('OAuth.params', $OAuthParams);

            //Off we go
            return $this->redirect(array('action' => 'authorize'));
        } else {
            $this->Session->setFlash(__('Username or password is incorrect'), 'default', array(), 'auth');
        }
    }
    $appName = $this->applicationDetails['name'];
    $this->set(compact('OAuthParams','appName'));
}

当前的测试方法。

/**
 * testAccessToken method
 * 1. Get the authorization code (/oauth/authorize?response_type=code&client_id=CLIENT_ID&client_secret=CLIENT_SECRET)
 * 2. Retrieve the token (/oauth/token?grant_type=authorization_code&code=CODE_RETURNED&client_id=CLIENT_ID&client_secret=CLIENT_SECRET)
 * 3. Parse the token from the returned data
 * @return void

public function testAccessToken(){
    //@link http://stackoverflow.com/questions/8183396/dealing-with-security-component-in-a-cakephp-2-test-case
    $this->OAuth = $this->generate('OAuth', array(
        'components' => array(
            'Security' => array('_validatePost'),
        )
    ));
    $this->OAuth->Security->expects($this->any())
        ->method('_validatePost')
        ->will($this->returnValue(true));

    $get_data = array(

            'username' => 'test_user_1',
            'passwd' => 'tester'
        )
    );

    $resultPost = $this->testAction(
        '/oauth/login', 
        array(
            'method' => 'post',
            'data' => $post_data
        )

    debug($resultPost);

    $data_for_code = array(

        'Authorize' => array(

    debug($code);

尝试了以下方法，但没有成功。

$this->OAuth = $this->generate(
    'OAuth',
    array(
        'components' => array(
            'Security' => array( '_validatePost' ),
            'Auth' => array('loggedIn','user')
        ),
        'methods' => array(
            'getAuthorizeParams'
        )
    )
);
$data = array(
    'response_type' => 'code',
    'client_id' => getenv('THREE_SCALE_APP_ID'),
    'client_secret' => getenv('THREE_SCALE_APP_KEY')
);
$this->OAuth->expects($this->any())
    ->method('getAuthorizeParams')
    ->will($this->returnValue($data));

$loginData = array(
    'User' => array(
        'client_id' => getenv('THREE_SCALE_APP_ID'),
        'client_secret' => getenv('THREE_SCALE_APP_KEY'),
        'response_type' => 'code',
        'state' => '',
        'scope' => '',
        'redirect_uri' => 'https://myurl.com/api/myCallbackMethod',
        'username' => 'test_user_1',
        'passwd' => 'tester'
    )
);

//test login action
$resultPost = $this->testAction(
    '/oauth/login?response_type=code&client_id=' . getenv('THREE_SCALE_APP_ID') . '&client_secret=' . getenv('THREE_SCALE_APP_KEY'), 
    array(
        'method' => 'post',
        'data' => $loginData
    )
);
debug($resultPost);

$data = array(
    'accept' => 'Yep',
    'Authorize' => array(
        'client_id' => getenv('THREE_SCALE_APP_ID'),
        'client_secret' => getenv('THREE_SCALE_APP_KEY'),
        'response_type' => 'code',
        'state' => '',
        'scope' => ''
    )
);

$result = $this->testAction(
        '/oauth/authorize', 
        array(
            'data' => $data, 
            'method' => 'post'
        )
    );
debug($result);

Answer 1

模拟 getAuthorizeParams() 函数以返回您想要的值。

您要模拟的 OAuth 中的函数是带有 'methods' 键的字符串数组，即：

$this->generate(
    'OAuth', 
    array(
        'methods' => array(
            'getAuthorizeParams'
        ),
        'components' => array(
            ...
        )
    )
);

然后在调用testAction() 方法之前：

$this->OAuth->expects($this->once())
    ->method('getAuthorizeParams')
    ->will($this->returnValue($YOUR_EXPECTED_VALUE));
