如何在 golang 中保存会话

Question

我正在尝试使用大猩猩会话和 securecookie 在我的 golang 后端中保存已登录的用户 ID。这是我的包裹会议：package sessionimport (    "fmt"    "net/http"    "github.com/gorilla/securecookie"    "github.com/gorilla/sessions")var store = sessions.NewCookieStore(securecookie.GenerateRandomKey(32))//GetSessionLoggedID returns loggedIDfunc GetSessionLoggedID(r *http.Request) int {    storeAuth, _ := store.Get(r, "authentication")    if auth, ok := storeAuth.Values["loggedID"].(bool); ok && auth {        return storeAuth.Values["loggedID"].(int)    }    fmt.Println("none found")    return 0}//SetSessionLoggedID sets cookie session user IDfunc SetSessionLoggedID(w http.ResponseWriter, r *http.Request, id int) {    storeAuth, err := store.Get(r, "authentication")    if err != nil {        fmt.Println(err.Error())    }    storeAuth.Options = &sessions.Options{HttpOnly: true, Secure: true, MaxAge: 2628000, Path: "/"}    storeAuth.Values["loggedID"] = id    storeAuth.Save(r, w)}我有另一个包可以验证登录用户的电子邮件/密码。这是功能：func (handler *UserHandler) checkPassword(w http.ResponseWriter, r *http.Request) {    var body struct {        Email    string        Password string    }    err := json.NewDecoder(r.Body).Decode(&body)    if err != nil {        http.Error(w, err.Error(), http.StatusInternalServerError)        return    }    loggedID, err := handler.UserUsecase.PasswordMatch(body.Email, body.Password)    if err != nil || loggedID == 0 {        http.Error(w, "Could not authenticate user", http.StatusUnauthorized)        return    }    session.SetSessionLoggedID(w, r, loggedID)    json.NewEncoder(w).Encode(struct {        ID int `json:"id"`    }{loggedID})}返回的 ID 是正确的。但是会话并没有像我希望的那样保存。session.GetSessionLoggedID(r)如果我在 checkpassword 函数的末尾添加一个，我会得到“未找到”。我错过了什么？

// watch this line

if auth, ok := storeAuth.Values["loggedID"].(bool); ok && auth {

storeAuth.Values["loggedID"]不是bool，ok也是false，然后你得到“未找到”

改成

    if auth, ok := storeAuth.Values["loggedID"]; ok{

        return auth.(int)

    }

    fmt.Println("none found")
