我一直在尝试从 AWS Lambda 连接到 Admob API，以不时自动从报告中提取一些值。我已经成功地将google-auth-library-nodejs放到了一个层中，并且我正在尝试使用它来连接到 Admob API。

我已确保为我的服务帐户提供所有者角色，并且已将必要的 GOOGLE_APPLICATION_CREDENTIALS 路径添加到环境变量。

这是我添加到我的 Lambda 的代码：

const {GoogleAuth} = require('google-auth-library');    
exports.handler = (event, context, callback) => {

    async function main() {
      const auth = new GoogleAuth({
        scopes: ['https://www.googleapis.com/auth/admob.report'],
      });

      const client = await auth.getClient();

      //console.log("client", JSON.stringify(client));

      const url = `https://admob.googleapis.com/v1/accounts`;
      const res = await client.request({ url });
      console.log("res: ", JSON.stringify(res.data));
    }

    main().catch(console.error);
};

当我运行代码时，我收到以下错误：

      reason: 'unauthorized'
    }
  ]
}

我一直试图通过在谷歌上搜索、堆栈溢出、阅读有关连接到 Admob API 的教程以及阅读库的代码来找到我的错误。如果有人能指出我的解决方案，我将不胜感激。

问题是您正在尝试使用需要 OAuth 用户凭据的服务帐户。您将需要实施 OAuth 2 流程，用户在其中输入他们的 Google 用户名和密码。

AdMob：请求的授权

有关如何创建 node.js OAuth 2 客户端的信息，请参阅以下 Google 示例。
