Question

我正在尝试在我的应用程序中使用Google Cloud Translation API，但每当我尝试翻译某些内容时，都会遇到此错误的有效API错误。

我已经完成了快速启动步骤，但没有奏效。 https://cloud.google.com/translate/docs/quickstart

我已经尝试过客户端库身份验证中的步骤，但是没有用。 https://cloud.google.com/translate/docs/reference/libraries

Answer 1

API密钥错误表示您未正确创建或使用密钥。您需要执行以下操作才能使密钥起作用：
1）创建一个服务帐户[1]
2）为上述服务帐户[2]创建密钥。
3）将密钥下载到某个位置，例如本地路径
4）将环境变量GOOGLE_APPLICATION_CREDENTIALS设置为密钥的文件路径，请参阅快速入门教程中的示例

在GCP控制台中执行1）和2），在Cloud Shell中执行3）和4）是最简单的。

[2] https://cloud.google.com/iam/docs/creating-managing-service-account-keys#creating_service_account_keys

Answer 2

如果您正在使用客户端库，并且已经下载了服务帐户json文件，请尝试以下

 // Instantiates a client
 const translate = new Translate(
        {
                projectId: 'your project id', //eg my-project-0o0o0o0o'
                keyFilename: 'path of your service acount json file' //eg my-project-0fwewexyz.json
        }
    );

代替

  // Instantiates a client
  const translate = new Translate({projectId});

这样，您只需要服务帐户json文件和启用的特定API

Answer 3

我也尝试执行this示例程序。我遵循了same的说明。但是当我执行时，我遇到了同样的错误（请求缺少有效的API密钥）。

我在示例程序中更改了一行。

代替

Translate translate = TranslateOptions.getDefaultInstance().getService();

我添加了

Translate translate = TranslateOptions
            .newBuilder()
            .setCredentials(
                ServiceAccountCredentials
                            .fromStream(new FileInputStream(
                                    "YourCredentialFilePath.json")))
            .build().getService();

现在可以使用了。

修复后的示例代码。

// Imports the Google Cloud client library
import java.io.FileInputStream;
import com.google.auth.oauth2.ServiceAccountCredentials;
import com.google.cloud.translate.Translate;
import com.google.cloud.translate.Translate.TranslateOption;
import com.google.cloud.translate.TranslateOptions;
import com.google.cloud.translate.Translation;

public class QuickstartSample {
   public static void main(String... args) throws Exception {
      //Instantiates a client
      //Removed next line
      //Translate translate = TranslateOptions.getDefaultInstance().getService();
      //Added this line
      Translate translate = TranslateOptions
            .newBuilder()
            .setCredentials(
            ServiceAccountCredentials
                            .fromStream(new FileInputStream(
                                    "YourCredentialFilePath.json")))
            .build().getService();

      //The text to translate
      String text = "Hello, world!";

      //Translates some text into Russian
      Translation translation =
         translate.translate(
              text,
              TranslateOption.sourceLanguage("en"),
              TranslateOption.targetLanguage("ru"));


      System.out.printf("Text: %s%n", text);
      System.out.printf("Translation: %s%n", translation.getTranslatedText());
   }
}

Google Cloud Translation API请求缺少有效的API密钥
