tp6 跨域 自带全局中间件不满足使用 headers 存在自定义字段

建议 

header("Access-Control-Allow-Origin:*");
header("Access-Control-Allow-Methods:GET, POST, OPTIONS, DELETE");
header("Access-Control-Allow-Headers:token,DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type, Accept-Language, Origin, Accept-Encoding");

加到 public/index,php 里面
