Access to XMLHttpRequest at 'http://crouter.yunzongnet.com...' from origin 'http://localhost:11305' has been blocked by CORS policy: Request header field authorization is not allowed by Access-Control-Allow-Headers in preflight response.
这个报错是什么意思?谁的问题?怎么改?
这是跨域问题,前端能搞定,后端也能搞定,后端可以通过设置Access-Control-Allow去解决,前端如果使用的是vue-cli的话,可以通过config/index.js里面proxyTable配置去进行解决
