在Go语言中使用Redis Stream实现消息队列时，如何解决user_id类型转换问题？

package main

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

type Message struct {
    UserID int `json:"user_id"`
    // ... other fields
}

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

    // 写入数据
    message := Message{UserID: 123}
    jsonData, err := json.Marshal(message)
    if err != nil {
        panic(err)
    }

    err = client.XAdd(&redis.XAddArgs{
        Stream: "mystream",
        Values: map[string]interface{}{
            "data": jsonData, // 将JSON数据作为值存储
        },
    }).Err()
    if err != nil {
        panic(err)
    }

    // 读取数据
    stream, err := client.XRead(&redis.XReadArgs{
        Streams: []string{"mystream", "0"},
        Block:   0,
    }).Result()
    if err != nil {
        panic(err)
    }

    for _, message := range stream[0].Messages {
        var receivedMessage Message
        json.Unmarshal([]byte(message.Values["data"].(string)), &receivedMessage) // 反序列化JSON数据
        fmt.Printf("Received User ID: %d\n", receivedMessage.UserID)
    }
}
