업데이트된 `mongodb srv` URL 구문을 사용하여 Go에서 MongoDB Atlas에 연결하는 방법은 무엇입니까?

package main

import (
    "context"
    "log"
    "time"

    "go.mongodb.org/mongo-driver/bson"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
)

func main() {
    mongoURI := "mongodb+srv://admin:[email protected]/dbname?ssl=true&retryWrites=true"

    // Set a timeout for connection establishment.
    ctx, cancel := context.WithTimeout(context.Background(), 3*time.Second)
    defer cancel()

    // Use mongo-go-driver to connect to Atlas.
    client, err := mongo.NewClient(options.Client().ApplyURI(mongoURI))
    if err != nil {
        log.Fatal(err)
    }
    if err = client.Connect(ctx); err != nil {
        log.Fatal(err)
    }
    defer client.Disconnect(ctx)

    // Now you can perform database operations as usual.
    database := client.Database("go")
    collection := database.Collection("atlas")
    err = collection.InsertOne(ctx, bson.M{"username": "testuser"})
    if err != nil {
        log.Fatal(err)
    }
}
