折腾:
【未解决】vue-admin-template中如何用vuejs去发送REST的api的POST请求并返回和解析json字符串
期间,去测试api调用,结果报错:

javascript – how to fix ‘Access to XMLHttpRequest has been blocked by CORS policy’ Redirect is not allowed for a preflight request only one route – Stack Overflow
此处,暂时从客户端入手
chrome浏览器,去试试
插件:Allow-Control-Allow-Origin
还是要从后端入手才行:
【已解决】给java的spring boot中后端加上CORS支持
然后就自然解决了此处问题了。
