在CakePHP中将两个JSON响应组合在一起

在我的CakePHP应用程序中,我在beforeFilter中执行一些操作,以传递有关用户或身份验证等的响应的额外JSON数据。

例如:

public function beforeFilter()
{
    $this->Auth->allow(array('index'));

    // If the request is either JSON or XML
    if ( $this->params['ext'] == 'json' || $this->params['ext'] == 'xml' )
    {
        if( $this->Auth->user() )
        {
            // User is logged in so send userdata and usual response will also be passed
            $response = array('meta' => 
                array(
                    'auth' => true,
                    'user_id' => $this->Auth->user('id')
                )
            );
            echo json_encode($response);
        }
        else
        {
            $requiresAuth = !in_array($this->params['action'], $this->Auth->allowedActions);
            if ($requiresAuth)
            {
                $response = array('meta' => 
                    array(
                        'auth' => false
                    )
                );
                echo json_encode($response);
                exit; // exit so no other responses go through
            }
            else
            {
                // Send JSON usual response
                $response = array('meta' => 
                    array(
                        'auth' => false
                    )
                );
                echo json_encode($response);
            }
        }
    }

    parent::beforeFilter();

}

这用于为移动应用构建我的RESTful API。这里的问题是完整返回的JSON如下所示:

{
    "meta": {
        "auth": false,
    }
} {
    "posts": [{
        "Post": {
            "id": "136",
            "user_id": "8",
            "datetime": "2012-09-11 15:49:52",
            "modified": "2012-09-16 15:31:38",
            "title": "Where is good to eat in New York?",
            "slug": "Where_is_good_to_eat_in_New_York",
            "content": "Preferably italian or mexican and with a good atmosphere.\r\n\r\nAlso within the **Manhattan** area!",
            "status": "1",
            "promoted": "0",
            "latitude": "53.6570794",
            "longitude": "-1.8277604"
        },...

正如您所看到的,两个JSON对象没有正确组合在一起......我该如何解决这个问题?

使用CakePHP 2.3

答案 0 :(得分:0)

解决方案如下:

1)不要回复beforeFilter()函数中的任何内容 - 它会破坏单元测试。

2)在app_controller中创建一个名为$ extra_data;

的受保护变量

3)你有echo语句,只需将$ extra_data设置为$ response;

4)在你的控制器动作中回显你的主json,检查!空($ this-> extra_data)如果这是真的,请将您的主动作响应与额外数据合并,并将其设置为您的视图以在那里作为json回显。
