tp6解决跨域问题

• 终端中输入命令 新建一个Cross中间件
  php think make:middleware Cross

* 设置跨域
     * @param $request
     * @param \Closure $next
     * @return mixed|void
     */
    public function handle($request, \Closure $next)
    {
        header('Access-Control-Allow-Origin: *');
        header('Access-Control-Max-Age: 1800');
        header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE');
        header('Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-CSRF-TOKEN, X-Requested-With, Token');
        if (strtoupper($request->method()) == "OPTIONS") {
            return Response::create()->send();
        }
        return $next($request);
    }

• 在app下的middleware.php中使用中间件

<?php
// 全局中间件定义文件
return [
    // 全局请求缓存
    // \think\middleware\CheckRequestCache::class,
    // 多语言加载
    // \think\middleware\LoadLangPack::class,
    // Session初始化
    // \think\middleware\SessionInit::class
    //解决跨域问题 自定义Cross中间件
    \app\middleware\Cross::class
];
