Google Cloud Translate-403禁止缺少API金钥

Question

我通过Google Cloud Transalte API并决定对我的应用程序使用Java平台

根据文档，使用必需的jar测试了以下代码。 这段代码在我的日食中工作正常

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

        String name = rs.getString("name");
        Translation translation1 = translate.translate(name);
        String TransalateName = translation1.getTranslatedText();

但是，当将此代码导出到jar中并在Shell脚本/ Unix服务器中运行时，出现以下错误消息，权限已定义-请求缺少有效的API密钥。 我如何以及在哪里可以在Java代码中使用API​​密钥，我有一个授权的服务帐户。

我已经使用我的服务帐户尝试了Google transalte，它工作正常，下面是示例。 但是我不确定如何在JAVA代码中使用此密钥

CURL命令-运行正常

curl -X POST \
     -H "Authorization: Bearer "AUTH_TOKEN_HERE \
     -H "Content-Type: application/json; charset=utf-8" \
     --data "{
  'q': '你好',
  'target': 'en',
  'model': 'nmt',
}" "https://translation.googleapis.com/language/translate/v2"

错误：

您错过了对GoogleAPI.setKey的调用。

import com.google.api.GoogleAPI;
import com.google.api.translate.Language;
import com.google.api.translate.Translate;

GoogleAPI.setKey(API_KEY);
GoogleAPI.setHttpReferrer("https://...");
// normally you would catch errors
Translate.DEFAULT.execute(sourceText, Language.fromString(sourceLanguageCode),
            Language.fromString(targetLanguageCode));

参见例如https://www.programcreek.com/java-api-examples/?api=com.google.api.GoogleAPI 。 我必须说，令人失望的是，谷歌云文档中没有示例（我能找到）。
