 * 公用的方法  返回json数据，进行信息的提示
 * @param $status 状态
 * @param string $message 提示信息
 * @param array $data 返回数据
 */
function showMsg($status,$message = &#39;&#39;,$data = array()){
    $result = array(
        &#39;status&#39; => $status,
        &#39;message&#39; =>$message,
        &#39;data&#39; =>$data
    );
    exit(json_encode($result));
}

2. Configure composer.json
