我读的文件,我不能够得到它如何获得Security.salt从价值app.php在Cakephp 3.我试图这样做

$salt = Configure::read('Security.salt');

导入以下库

use Cake\Core\Configure;
use Cake\Core\Configure\Engine\PhpConfig;

请帮助.

Cakephp version is 3.4

使用CakePHP 3.4,PHP 7.0.

我正在尝试使用一个非常简单的控制器方法来输出一些JSON.它输出"无法修改标题...".

public function test() {
    $this->autoRender = false;
    echo json_encode(['method' => __METHOD__, 'class' => get_called_class()]);
}

浏览器输出

{"method":"App\\Controller\\SomeController::test", "class":"App\\Controller\\SomeController"}

Warning (512): Unable to emit headers. Headers sent in file=...
Warning (2): Cannot modify header information - headers already sent by (output started at ...)
Warning (2): Cannot modify header information - headers already sent by (output started at ...)

我完全理解为什么PHP抱怨这个.问题是为什么CakePHP会抱怨我该怎么办？

应该注意的是,CakePHP 2.x允许这样做.

我尝试迁移到 3.4，但在发送 json 对象时遇到问题。到 3.3，我使用了以下代码：

$jsonSites = json_encode([
    'reqLocation' => [
        'latitude' => $latitude,
        'longitude' => $longitude
    ],
    'sites' => $sitesList,
    'discoveryBooks' => $discoveryBooksList,
    'deleteSites' => !empty($inDeviceSites) ? [$inDeviceSites] : [],
    'deleteBooks' => !empty($inDeviceBooks) ? [$inDeviceBooks] : []
]);

$this->response->type('application/json');
$this->response->body($jsonSites);

我的客户收到了这样的对象：

{
  "reqLocation": {
    "latitude": 48.080563,
    "longitude": 4.4649
  },
  "sites": [
