如何在Go Gin框架使用Redis作为Session引擎时以明文形式保存数据？

import (
    "encoding/json"
    "github.com/gin-gonic/gin"
    "github.com/go-redis/redis/v8"
)

type RedisSessionStore struct {
    client *redis.Client
}

func NewRedisSessionStore(client *redis.Client) *RedisSessionStore {
    return &RedisSessionStore{client: client}
}

func (store *RedisSessionStore) Save(session *gin.Context, data interface{}) error {
    jsonData, err := json.Marshal(data)
    if err != nil {
        return err
    }
    err = store.client.Set(session.Request.Context(), session.GetString("session_id"), jsonData, 0).Err()
    return err
}

func (store *RedisSessionStore) Load(session *gin.Context) (interface{}, error) {
    val, err := store.client.Get(session.Request.Context(), session.GetString("session_id")).Result()
    if err == redis.Nil {
        return nil, nil // Session not found
    }
    if err != nil {
        return nil, err
    }
    var data interface{}
    err = json.Unmarshal([]byte(val), &data)
    return data, err
}

func (store *RedisSessionStore) Delete(session *gin.Context) error {
    return store.client.Del(session.Request.Context(), session.GetString("session_id")).Err()
}

r := gin.Default()
client := redis.NewClient(&redis.Options{
    Addr:     "localhost:6379",
    Password: "", // No password set
    DB:       0,  // Use default DB
})

store := NewRedisSessionStore(client)
r.Use(sessions.Sessions("mysession", store))

// ... your Gin routes ...
