vue-think PHP跨域问题请教

vhost、入口文件index.php 我都分别配置过跨域

     location / {
      # proxy_pass xx.xxx.xyz
      # proxy_pass http://xxx.xxx.xyz
      add_header 'Access-Control-Allow-Origin' *;
      add_header 'Access-Control-Allow-Credentials' 'true';
      add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,X-Requested-With';
      add_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE';  
}

但是没任何效果：
