如何在beego框架的子域之间共享cookie

Question

We intend to set cookie for *.1234tv.com in login.1234tv.com. However it does not work.

I have configure the container as below:

beego.InsertFilter("*", beego.BeforeRouter, cors.Allow(&cors.Options{
    AllowAllOrigins: true,
    AllowOrigins:     []string{"http://*.1234tv.com"},
    AllowMethods:    []string{"GET", "POST", "PUT", "DELETE","PATCH","HEAD", "OPTIONS"},
    AllowHeaders:    []string{"Origin", "Authorization", "Access-Control-Allow-Origin", "Content-Type"},
    ExposeHeaders:   []string{"Content-Length", "Access-Control-Allow-Origin"},
    AllowCredentials: true,
}))

and set cookie in controller like this:

this.Ctx.SetCookie("UNION_TOKEN", utoken, 3600*24*7,"/", ".1234tv.com",false,false)

Answer 1

The cause is set-cookie by response does not work. 1.Since it is an across sites Ajax request, .withCredentials() can active the ability of set cookie by response.

$.ajax( {
   /* Setup the call */
   xhrFields: {
     withCredentials: true
   }
 });

2.On the side of response server, "Access-Control-Allow-Credentials" must be "true" and "Access-Control-Allow-Origin" must not be "*" and "Access-Control-Allow-Origin" could be "http://*.domain.com".
