I'm new to Gin and Gin sessions, and I have a weird problem I cannot explain: It seems that session data I write in my controller can't be accessed from my middlware.
Allow me to demonstrate:
I do the following in my controller:
func OidcCallBack(c *gin.Context) {
...
// store user info and redirect to original location
userJsonData, err := json.Marshal(*user)
if err != nil {
log.Errorf("error encoding user data: %s", err.Error())
}
session.Set(SessionUserInfo, string(userJsonData))
session.Save()
}
In my middleware, I want to read this session data:
func OidcMiddleware() gin.HandlerFunc {
return func(c *gin.Context) {
// get our session variables
session := sessions.Default(c)
// some test code, this works btw
session.Set("bla", "test")
session.Save()
blavar := session.Get("bla")
// get our userinfo
userinfo := session.Get(controllers.SessionUserInfo) // this results in nil
log.Debug(blavar)
if userinfo == nil {
log.Debugf("filter incoming url: %s", c.Request.URL.String())
session.Set(controllers.SessionRedirectTarget, c.Request.URL.String())
session.Save()
c.Redirect(http.StatusFound, controllers.AuthLogin)
c.Abort()
}
c.Next()
}
}
When I look in my debugger, I notice that the data set in the controller, ended up in a different place of session.store.MemStore.cache.data:
session data set in the middleware ends up in data[0], and the data set in the controller ends up in data1.
Can someone explain me what I need to do to make sure all data ends up in the same spot, and also explain me why this happens? I can't find in any info on this in the readme file.
