When allowCredentials is true, allowedOrigins cannot contain thespecial value "*"since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.出现该问题是跨域问题，当allowCredentials为true时，allowingOrigins不能包含特殊值" *"，因为无法在" Access-Control-Allow-Origin"响应标头上设置。
处理方法是：首先找打你后端跨域设置文件，将方法中的addAllowedOrigin("")替换成addAllowedOriginPattern("")
