这是一个 GoLang,Firebase AdminSDK 问题。此示例用于循环访问 FireStore 数据库中的所有文档。我怎样才能得到文档名称?换句话说:如果集合名称是JohnyCollection,并且JohnyCollection有 20 个名为 ( Document1, Document2.... Document20) 的文档,我如何在 golang 代码中获取文档名称?//========================================package mainimport ( "context" "fmt" "log" "firebase.google.com/go" "google.golang.org/api/iterator" "google.golang.org/api/option")func check(e error) { if e != nil { panic(e) }}func main() { ctx := context.Background() sa := option.WithCredentialsFile("./scai-qit-fb-adminsdk.json") app, err := firebase.NewApp(ctx, nil, sa) if err != nil { log.Fatalf("error initializing app: %v\n", err) } client, err := app.Firestore(ctx) if err != nil { log.Fatal(err) } defer client.Close() iter := client.Collection("COMPLEX_NONACS").Documents(ctx) for { doc, err := iter.Next() if err == iterator.Done { break } if err != nil { log.Fatalf("Failed to iterate: %v", err) } //This part works. WIll return a Map of each Document fmt.Println("--------------------------/n") fmt.Println(doc.Data()) // This is the question. How do I get the INDEX name of the Document? // something like... fmt.Println(doc.Index_value_or_something_that_returns_IndexName()) // for example... // { // "ABC":{"line1":"yabba dabba","line2":"dingo dong"}, // "DEF":{"line1":"hooty tooty","line2":"blah blah"} // } // How to just get the "ABC" and "DEF" }}
