session - 错误 : non-declaration statement outside function body on redisstor

Question

关注rediststor docs , 我想修改 this使用redis存储 session 的代码。这是我想出的:

package session

import (
    "net/http"

    "github.com/gorilla/sessions"
    redisStore "gopkg.in/boj/redistore.v1"
)
var store *redisStore.RediStore
var Name string
var err error

store, err = redisStore.NewRediStore(10, "tcp", ":6379", "", []byte("secret-key"))
if err != nil  {
  log.Fatal("error getting redis store : ", err)
}
defer store.Close()

// Session stores session level information
type Session struct {
    Options   sessions.Options `json:"Options"`   
    Name      string           `json:"Name"`      
    SecretKey string           `json:"SecretKey"` 
}

// Configure the session cookie store
func Configure(s Session) {
    Store := store
    Store.Options = &s.Options
    Name = s.Name
}

// Instance returns a new session, never returns an error
func Instance(r *http.Request) *sessions.Session {
session, _ := Store.Get(r, Name)
return session
 }

但是我得到这个错误:

vendor/app/shared/session/session.go:19:1: syntax error: non-declaration statement outside function body

我想知道这里出了什么问题，我该如何解决？

Answer 1

您可以将有问题的代码放在 Configure 函数中，以替换初始化 CookieStore 的原始代码。

var (
    // Store is the *redis* store
    Store *redisStore.RediStore
    // Name is the session name
    Name string
)

// ...

// Configure the session cookie store
func Configure(s Session) {
    var err error
    Store, err = redisStore.NewRediStore(10, "tcp", ":6379", "", []byte("secret-key"))
    if err != nil  {
        log.Fatal("error getting redis store : ", err)
    }

    Store.Options = &s.Options
    Name = s.Name
}
