}
1 在app顶层创建文件common\behavior\CronRun.php 写入以上代码
2 添加钩子事件
在application \tags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

// 视图内容过滤
'view_filter' => [],
// 日志写入
'log_write' => [],

'app_end' => [

];
使应用目录执行开始执行文件
$get=\request()->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
