GAE去用户注销奇怪的行为

Question

我不知道为什么第一个函数完美运行，第二个函数永远不会注销，我总是登录。定义的结构对应一个模板变量。

最奇怪的是，在两个不同的处理程序中，对LogoutURL的调用会生成两个不同的链接（不仅是返回URL，这两个的结构是不同的[索引页面的一个有效]以myapp-notworking-000开头。 appspot.com然后_ah / logout URL和管理页面以https://google.com/accounts和所有）开头。我在这里错过了什么？ GAE为何如此复杂？

import (
    "appengine"
    "appengine/user"
    "fmt"
    "html/template"
    "net/http"
)

var templates = template.Must(template.ParseGlob("static/tmpl/*"))

type AdminPage struct {
    Admin_email string
    LogoutUrl   string
}

func init() {
    http.HandleFunc("/", Index)
    http.HandleFunc("/admin", Admin)
}

func Index(w http.ResponseWriter, r *http.Request) {
    w.Header().Set("Content-type", "text/html; charset=utf-8")
    c := appengine.NewContext(r)
    u := user.Current(c)
    if u == nil {
        url, _ := user.LoginURL(c, "/")
        fmt.Fprintf(w, `<a href="%s">Sign in or register</a>`, url)
        return
    }
    url, _ := user.LogoutURL(c, "/")
    fmt.Fprintf(w, `Welcome, %s! (<a href="%s">sign out</a>)`, u, url)
}

func Admin(w http.ResponseWriter, r *http.Request) {
    c := appengine.NewContext(r)
    u := user.Current(c)
    an := AdminPage{"", ""}
    var templ = ""

    if u == nil {
        url, err := user.LoginURL(c, r.URL.String())
        if err != nil {
            http.Error(w, err.Error(), http.StatusInternalServerError)
            return
        }
        w.Header().Set("Location", url)
        w.WriteHeader(http.StatusFound)
        return
    }
    c.Debugf("User present %v", u)
    an.Admin_email = u.Email
    templ = "adminIndex"
    url, err := user.LoginURL(c, "/admin")
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
    an.LogoutUrl = url
    err = templates.ExecuteTemplate(w, templ, an)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
}
