ThinkPHP 5 中AJAX跨域请求头设置方法

最近用thinkphp做项目，在测试环境时，存在接口的测试问题。在tp官网也没能找到相关的解决方法。自已看了一下源码，有如下的解决方案。 在项目目录下面，创建common/behavior/CronRun.php文件，文件内容如下： 复制 <?php /** * Created by PhpStorm. * User: LiuYang * Date: 2017/3/9 * Time: 19:37 */   namespace app\common\behavior;   use think\Exception; use think\Response;   class CronRun { public function run(&$dispatch){ $host_name = isset($_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; } } } 接着在项目中（tags.php）配置行为动作，如下： 复制 <?php // +---------------------------------------------------------------------- // | ThinkPHP [ WE CAN DO IT JUST THINK ] // +---------------------------------------------------------------------- // | Copyright (c) 2006~2016 http://thinkphp.cn All rights reserved. // +---------------------------------------------------------------------- // | Licensed ( http://www.apache.org/licenses/LICENSE-2.0 ) // +---------------------------------------------------------------------- // | Author: liu21st <[email protected]> // +----------------------------------------------------------------------   // 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' ], ];
