Go를 사용하여 MongoDB에서 _id로 문서를 찾는 방법은 무엇입니까?

<code class="go">import (
    "context"
    "go.mongodb.org/mongo-driver/bson"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
    "go.mongodb.org/mongo-driver/mongo/primitive"
)

func main() {
    ctx := context.Background()

    // Create a client
    client, err := mongo.Connect(ctx, options.Client().ApplyURI("mongodb://<host>:<port>"))
    if err != nil {
        // handle error
    }
    defer client.Disconnect(ctx)

    // Get a collection
    collection := client.Database("database").Collection("collection")

    // Parse the ObjectID from hexadecimal string
    id, err := primitive.ObjectIDFromHex("5c7452c7aeb4c97e0cdb75bf")
    if err != nil {
        // handle error
    }

    // Find the document by _id
    result := collection.FindOne(ctx, bson.M{"_id": id})
}</code>
