关于本地前端调用后台接口报错跨域问题

[joyld0712]

连接浏览器就报错
Access to XMLHttpRequest at 'http://localhost/vue-admin-php/public/index.php/admin/login/out' from origin 'http://172.29.130.120:8081' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
请问下这是什么情况？明明都是在本地的
请求大大指点下

不管是不是在本地，只要域名和端口号不一样都属于跨域。也可以去 Google 下，详细的看看跨域的解释哦
