使用带有golang的查询中的ID从Firestore GCP获取文档

import (
    "context"
    "fmt"
    "log"

    "cloud.google.com/go/firestore"
    "google.golang.org/api/option"
)

ctx := context.Background()
projectID := "your-project-id"
client, err := firestore.NewClient(ctx, projectID, option.WithCredentialsFile("path/to/serviceAccountKey.json"))
if err != nil {
    log.Fatalf("Failed to create Firestore client: %v", err)
}
defer client.Close()

docID := "your-document-id"
docRef := client.Collection("your-collection").Doc(docID)
doc, err := docRef.Get(ctx)
if err != nil {
    log.Fatalf("Failed to get document: %v", err)
}
if doc.Exists() {
    fmt.Printf("Document data: %#v\n", doc.Data())
} else {
    fmt.Println("Document does not exist")
}
