java - 为什么 Google Cloud API 尝试以最终用户身份连接？

问题描述

我正在尝试使用 Google Cloud Translate API。我从服务帐户生成了一个 JSON 文件，并将其设置GOOGLE_APPLICATION_CREDENTIALS为保存 JSON 文件的位置。然后我在这样的程序中使用它：

import com.google.cloud.translate.*;
...
Translate translate = TranslateOptions.getDefaultInstance().getService();
Translation translation = translate.translate(message);

但我收到以下错误

com.google.cloud.translate.TranslateException: Your application has authenticated using end user credentials from the Google Cloud SDK or Google Cloud Shell which are not supported by the translate.googleapis.com. We recommend that most server applications use service accounts instead. For more information about service accounts and how to use them in your application, see https://cloud.google.com/docs/authentication/

这是我的 JSON 文件：

  "type": "service_account",
  "project_id": "ecstatic-motif-220300",
  "private_key_id": "keyid",
  "private_key": "somekey",
  "client_email": "kokosole@ecstatic-motif-220300.iam.gserviceaccount.com",
  "client_id": "100208235593900994013",

}

谁能解释这里发生了什么？我该如何解决？甚至没有安装 Google Cloud SDK。

解决方案

您已作为用户进行身份验证，而 API 需要一个服务帐户，看到您使用带有“import com.google.cloud.translate.*;”的客户端库 陈述。您可以在“翻译 API 客户端库”页面上的设置身份验证段落中找到相关详细信息。
