場景：

請求頭設定token後頁面報錯：has been blocked by CORS policy:Request header field token is not allowed by Access-Control-Allow-Headers in preflight response.

並且後臺跨域相關已配置：Access-Control-Allow-Origin: *

解決：

需要後端在響應頭的 Access-Control-Allow-Headers 欄位設定允許前端請求時帶有的欄位值（檢查了一下，在攔截器的響應裡裡增加如下）
response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, accessToken, token");
