问ajax请求COS的jsonAPI，设置了CORS还是报跨域？

同题，设置好了CORS，ajax请求XML的api没有问题可以返回数据，但是请求JSON的api就报 Failed to load https://timeless-1255909651.cosgz.myqcloud.com/: Redirect from 'https://timeless-1255909651.cosgz.myqcloud.com/' to 'https://timeless-1255909651.cos.ap-guangzhou.myqcloud.com/' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.timelessq.com' is therefore not allowed access. 这里重定向了？ 怎么改？
