如何将mongodb数据解码为struct

import (
    "context"
    "fmt"
    "go.mongodb.org/mongo-driver/bson"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
)

type Person struct {
    Name  string `bson:"name"`
    Age   int    `bson:"age"`
    Email string `bson:"email"`
}

func main() {
    // 连接到 MongoDB
    client, err := mongo.Connect(context.TODO(), options.Client().ApplyURI("mongodb://localhost:27017"))
    if err != nil {
        fmt.Println("Failed to connect to MongoDB:", err)
        return
    }
    defer client.Disconnect(context.TODO())

    // 选择数据库和集合
    collection := client.Database("mydb").Collection("people")

    // 查询数据
    filter := bson.D{{"name", "John"}}
    var result Person
    err = collection.FindOne(context.TODO(), filter).Decode(&result)
    if err != nil {
        fmt.Println("Failed to decode MongoDB data:", err)
        return
    }

    // 打印结果
    fmt.Println("Name:", result.Name)
    fmt.Println("Age:", result.Age)
    fmt.Println("Email:", result.Email)
}
