Vue 加入 withCredentials 后无法进行跨域请求？

Question

Vue和django的前后端分离项目，之前通过在django中允许跨域访问实现了跨域请求，但为了使每个请求带上session信息，我设置了withCredentials ,即：

axios.defaults.withCredentials = true

然后跨域请求时会出现如下问题：

Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://localhost:8080' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

请问有人知道是什么问题吗？

Answer 1

服务端要做以下2个工作：

1. Access-Control-Allow-Origin 字段必须指定域名，不能为*

2. Access-Control-Allow-Credentials为true

Answer 2

后台支持options请求吗
