            $response = new Response('', 200, $headers);
            $dispatch['response'] = $response;
        }
    }
}

1　在app顶层创建文件commonehaviorCronRun.php 写入以上代码

2 添加钩子事件

在application ags下写入

// 应用行为扩展定义文件
return [
    // 应用初始化
    'app_init'     => [],
    // 应用开始
    'app_begin'    => [
        'app\common\behavior\CronRun'
    ],
    // 模块初始化
    'module_init'  => [],
    // 操作开始执行
    'action_begin' => [],
    // 视图内容过滤
    'view_filter'  => [],
    // 日志写入

    // 应用结束
    'app_end'      => [
        'app\common\behavior\CronRun'
    ],
];

　　使应用目录执行开始执行文件

 $get=
equest()->param('callback');
   　　　　　　　　　　　　　　　　　　　　//防止数据转json格式的时候中文进行了unicode转码
   $data=$get."(".json_encode($data,JSON_UNESCAPED_UNICODE).")";
   return $data;
//返回数据带上回调参数前段Vue就能正常显示返回数据
