我遇到了一些麻烦后，杜松子酒gonic书，这有助于到目前为止顺利移动杜松子酒。当我到了会议的一部分，似乎我击中了一个拦网。
我正在使用：

• macOS ventura上的macbook pro m1
• 转到1.21.1
• 杜松子酒1.9.1
• gin-contrib/sessions v0.0.5

我从gin-contrib/session开始使用以下代码

//main.go
import (
    "context"
    "github.com/gin-gonic/contrib/sessions"
    //redisStore "github.com/gin-contrib/sessions/redis"
    "github.com/gin-gonic/gin"
 )
router := gin.Default()
store, _ := sessions.NewRedisStore(10, "tcp", "localhost:6379", "", []byte("secret"))
//store, _ := redisStore.NewStore(10, "tcp", "localhost:6379", "", []byte("secret"))
router.Use(sessions.Sessions("recipes_api", store))
//auth handler
import (
    //...
    "crypto/sha256"
    "github.com/dgrijalva/jwt-go"
    //"github.com/gin-contrib/sessions"
    sessions2 "github.com/gin-gonic/contrib/sessions"
    //...
)
 
func (handler *AuthHandler) SignInHandler(c *gin.Context) {
//...
    if cur.Err() != nil {
        c.JSON(http.StatusUnauthorized, gin.H{"error": "Invalid username or password"})
        return
    }
    sessionToken := xid.New().String()
    session := sessions2.Default(c)
    session.Set("username", user.Username)
    session.Set("token", sessionToken)
    session.Save()
    c.JSON(http.StatusOK, gin.H{"message": "User signed in"})
}

上面的代码似乎在session.Default（c）或session2.Default（c）中中断了，所以无论我使用的是来自"github.com/gin-gonic/contrib/sessions"还是来自"github.com/gin-contrib/sessions"的session，它总是找不到键。它抛出如下错误

我在这里做错了一些事情，如果有人能为我提供一些帮助，我会很感激，这样我就可以向前推进了。谢谢
