一、在app顶层创建文件common\\behavior\\CronRun.php 写入以下代码

<?php
    /**
     * Created by PhpStorm.
     * User: qianglong
     * Date: 2018/1/15
     * Time: 17:56
     */
    namespace app\common\behavior;
     
    use think\Exception;
    use think\Response;
     
    class CronRun
    {
        public function run(&$dispatch){
            header("Access-Control-Allow-Origin:*");
            $host_name = isset($_SERVER['HTTP_ORIGIN']) ? $_SERVER['HTTP_ORIGIN'] : "*";
            $headers = [
                "Access-Control-Allow-Origin" => $host_name,
                "Access-Control-Allow-Credentials" => 'true',
                "Access-Control-Allow-Headers" => "x-token,x-uid,x-token-check,x-requested-with,content-type,Host"
            ];
            if($dispatch instanceof Response) {
                $dispatch->header($headers);
            } else if($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
                $dispatch['type'] = 'response';
                $response = new Response('', 200, $headers);
                $dispatch['response'] = $response;
            }
        }
    }

二、 添加钩子事件

在application \\tags下写入

<?php

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

接下来就可以跨域请求了
