Google Cloud "translate.NewClient: dialing: google: could not find default credentials"

问题

我正在尝试在Windows上（我的电脑）使用Google Translate API。我遇到了默认凭据的问题。

错误：**translate.NewClient: dialing: google: could not find default credentials.

我在Google Cloud中有足够的余额。

我已经启动了Translate API（API已启用）。

我添加了*$env:GOOGLE_APPLICATION_CREDENTIALS="KEY_PATH"*。

以下是您提供的代码的翻译：

  1. package main
  3. import (
  4. 	"context"
  5. 	"fmt"
  6. 	"log"
  8. 	"cloud.google.com/go/storage"

  10. 	"golang.org/x/text/language"
  11. 	"google.golang.org/api/iterator"
  12. 	"google.golang.org/api/option"
  13. )
  15. func translateTextWithModel(targetLanguage, text, model string) (string, error) {
  16. 	// targetLanguage := "ja"
  17. 	// text := "The Go Gopher is cute"
  18. 	// model := "nmt"
  20. 	ctx := context.Background()
  22. 	lang, err := language.Parse(targetLanguage)
  23. 	if err != nil {
  24. 		return "", fmt.Errorf("language.Parse: %v", err)
  25. 	}
  27. 	client, err := translate.NewClient(ctx)
  28. 	if err != nil {
  29. 		return "", fmt.Errorf("translate.NewClient: %v", err)
  30. 	}
  31. 	defer client.Close()
  33. 	resp, err := client.Translate(ctx, []string{text}, lang, &translate.Options{
  34. 		Model: model, // Either "nmt" or "base".
  35. 	})
  36. 	if err != nil {
  37. 		return "", fmt.Errorf("Translate: %v", err)
  38. 	}
  39. 	if len(resp) == 0 {
  40. 		return "", nil
  41. 	}
  42. 	return resp[0].Text, nil
  43. }
  45. func main() {
  46. 	Json_path := "C:/Users/Mels/Documents/GoogleTools/cred-9dfos6bb49f.json"
  47. 	ProjectID := "cred"
  48. 	fmt.Println("RUNNING...")
  49. 	explicit(Json_path, ProjectID)
  50. 	fmt.Println(translateTextWithModel("ja", "Hello World", "nmt"))
  51. }
  53. // explicit reads credentials from the specified path.
  54. func explicit(jsonPath, projectID string) {
  55. 	ctx := context.Background()
  56. 	client, err := storage.NewClient(ctx, option.WithCredentialsFile(jsonPath))
  57. 	if err != nil {
  58. 		log.Fatal(err)
  59. 	}
  60. 	defer client.Close()
  61. 	fmt.Println("Buckets:")
  62. 	it := client.Buckets(ctx, projectID)
  63. 	for {
  64. 		battrs, err := it.Next()
  65. 		if err == iterator.Done {
  66. 			break
  67. 		}
  68. 		if err != nil {
  69. 			log.Fatal(err)
  70. 		}
  71. 		fmt.Println(battrs.Name)
  72. 	}
  73. }

JSON文件：

  1. {
  2.   "type": "service_account",
  3.   "project_id": "xxxxxxx",
  4.   "private_key_id": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  5.   "private_key": "-----BEGIN PRIVATE KEY-----XXXXXXXX-----END PRIVATE KEY-----\n",

  13. }

希望这可以帮助到您！

I am trying to use Google Translate API on Windows(my own computer). I have an issue with default credentials.

I have enough balance in google cloud.

I started Translate API. (API Enabled)

如果库找不到默认凭据，那么你可以尝试使用凭据路径创建一个客户端。

即使这可能不是最好的选择（尽管我更喜欢它而不是环境变量），但它将帮助你更好地诊断问题。

为了使用凭据文件路径创建客户端，你需要导入google.golang.org/api/option，并使用WithCredentialsFile选项创建客户端。注意文档中提到的客户端可以使用附加选项创建：

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

以下是一个更完整的示例，展示如何使用选项创建客户端（根据需要将所需部分应用到你的当前代码中）：

  1. package main
  2. import (
  3. "cloud.google.com/go/translate"
  4. "context"
  5. "google.golang.org/api/option"
  6. )
  7. func main() {
  8. ctx := context.Background()
  9. client, err := translate.NewClient(ctx, option.WithCredentialsFile("/path/to/your/file"))
  10. if err != nil {
  11. // TODO: 处理错误。
  12. }
  13. // 使用客户端。
  14. // 完成后关闭客户端。
  15. if err := client.Close(); err != nil {
  16. // TODO: 处理错误。
  17. }
  18. }

（这只是文档中示例的副本，包含了额外的选项。）

英文:

If the library can't find the default credentials, then you can try to create a client with the credentials path.

Even if this might not be the best option for you (although I prefer it to the env variable), it'll help you diagnose the issue a little better.

In order to create the client with a path to the credentials file, you need to import google.golang.org/api/option, and create the client with the WithCredentialsFile option. Note in the docs that the client can be created with additional options:

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

A somewhat more complete example on how to create a client with options would be the following (apply the required parts to your current code as needed):

  1. package main
  2. import (
  3. "cloud.google.com/go/translate"
  4. "context"
  5. "google.golang.org/api/option"
  6. )
  7. func main() {
  8. ctx := context.Background()
  9. client, err := translate.NewClient(ctx, option.WithCredentialsFile("/path/to/your/file"))
  10. if err != nil {
  11. // TODO: handle error.
  12. }
  13. // Use the client.
  14. // Close the client when finished.
  15. if err := client.Close(); err != nil {
  16. // TODO: handle error.
  17. }
  18. }

(This is just a copy of the example in the docs with the additional option included.)

我解决了这个问题。我下载了"google cloud shell SDK"并使用了"gcloud auth application-default login"代码。SDK提供了一个JSON文件，我用新的JSON文件替换了它。

我不建议使用cloud.google.com/translate/docs/setup指南。直接使用Google Cloud SDK。

英文:

I solved the issue. I downloaded "google cloud shell SDK" and I used "gcloud auth application-default login" code. SDK provides a JSON file and I replaced it with new JSON file.

I do not recommend cloud.google.com/translate/docs/setup instructions. Direct use Google cloud SDK.
