如何用Go语言和Redis开发游戏后台

mkdir game_backend
cd game_backend
go mod init game_backend

go get GitHub.com/go-redis/redis/v8

package main

import (
    "context"
    "fmt"
    "github.com/go-redis/redis/v8"
)

func main() {
    // 创建Redis客户端
    client := redis.NewClient(&redis.Options{
        Addr:     "localhost:6379", // Redis服务地址和端口
        PassWord: "",               // Redis密码
        DB:       0,                // 默认的数据库编号
    })

    // 测试连接
    pong, err := client.Ping(context.Background()).Result()
    if err != nil {
        fmt.Println("Failed to connect to Redis:", err)
        return
    }
    fmt.Println("Connected to Redis:", pong)
}

// 存储玩家信息
func savePlayerInfo(client *redis.Client, playerId string, playerInfo map[string]interface{}) error {
    return client.HMSet(context.TODO(), "player:"+playerId, playerInfo).Err()
}

// 获取玩家信息
func getPlayerInfo(client *redis.Client, playerId string) (map[string]string, error) {
    return client.HGetAll(context.TODO(), "player:"+playerId).Result()
}

func handleLogin(client *redis.Client, playerId string) {
    // 检查玩家是否存在
    playerInfo, err := getPlayerInfo(client, playerId)
    if err != nil {
        fmt.Println("Failed to get player info:", err)
        return
    }

    if len(playerInfo) == 0 {
        // 玩家不存在，创建新的玩家信息
        playerInfo := map[string]interface{}{
            "name":   "TestPlayer",
            "level":  1,
            "score":  0,
            "energy": 100,
        }

        err := savePlayerInfo(client, playerId, playerInfo)
        if err != nil {
            fmt.Println("Failed to save player info:", err)
            return
        }
    }

    // 处理玩家登录逻辑...
}

func main() {
    client := redis.NewClient(&redis.Options{
        Addr:     "localhost:6379",
        Password: "",
        DB:       0,
    })

    playerId := "123456789"
    handleLogin(client, playerId)
}
