如何在CakePHP中返回正确的内容类型的JSON？ [英] How to return the correct content-type for JSON in CakePHP?

问题描述

我想设置Content-type头与一个AJAX的GET请求访问的JSON响应。我已经按照博客和面包店教程，但我总是收到text / html的从CakePHP的回来。我如何正确地设置Content-Type头？

I'm trying to set the content-type header for a JSON response accessed with an AJAX GET request. I've followed tutorials on blogs and the bakery but I always receive 'text/html' back from CakePHP. How do I set the content-type header correctly?

下面是我的code的时刻：

Here's my code at the moment:

public function admin_controller_actions_ajax()
{
    Configure::write('debug', 0);
    if ($this->RequestHandler->isGet()) {
        $this->autoRender = FALSE;

        $aco_id = $this->params['url']['aco_id'];
        $aro_id = $this->params['url']['aro_id'];

        assert('$aco_id != NULL && $aro_id != NULL &&
                is_numeric($aco_id) && is_numeric($aro_id)');

        $actions = $this->Resource->getActionsForController($aco_id, $aro_id);

        assert('is_array($actions) && is_array($actions[0])');

        /* I made RequestHandler part of the $components property */
        $this->RequestHandler->setContent('json');
        $this->RequestHandler->respondAs('json'); /* I've tried 'json', 'JSON', 'application/json' but none of them work */

        $this->set('json_content', json_encode(array('response' => $actions[0])));
        $this->layout = NULL;
        $this->render('/json/default');
    }
}


/* json/default.ctp */
<?php echo $json_content; ?>

任何帮助将是AP preciated。

Any help would be appreciated.

谢谢

推荐答案

阅读这后和<一href="http://cakephp.lighthouseapp.com/projects/42648/tickets/677-requesthandler-respondas-doesnt-always-work-for-ajax-calls">this,我得到了以下回归内容类型：应用程序/ JSON

After reading this and this, I got the following to return "Content-Type:application/json":

Configure::write('debug', 0);
$this->RequestHandler->respondAs('json');
$this->autoRender = false;            
echo json_encode($data);

使用jQuery的$ .getJSON方法，我仍然得到

With JQuery's $.getJSON method, I'm still getting

Resource interpreted as image but transferred with MIME type text/html.

但至少我的数据分析。

But at least my data is parsing.
