使用 api 密钥从服务器端检查 google play 订阅

Question

我想从我的 NodeJS 服务器检查我的客户订阅是否有效。

I am calling the following endpoint https://developers.google.com/android-publisher/api-ref/rest/v3/purchases.subscriptions/get with an api key having access to Google Play Developer Reporting API and Google Play Android Developer API但我的回应是

{
  "error": {
    "code": 401,
    "message": "API keys are not supported by this API. Expected OAuth2 access token or other authentication credentials that assert a principal. See https://cloud.google.com/docs/authentication",
    "errors": [
      {
        "message": "Login Required.",
        "domain": "global",
        "reason": "required",
        "location": "Authorization",
        "locationType": "header"
      }
    ],
    "status": "UNAUTHENTICATED",
    "details": [
      {
        "@type": "type.googleapis.com/google.rpc.ErrorInfo",
        "reason": "CREDENTIALS_MISSING",
        "domain": "googleapis.com",
        "metadata": {
          "method": "androidpublisher.SubscriptionPurchasesService.Get",
          "service": "androidpublisher.googleapis.com"
        }
      }
    ]
  }
}

有没有办法用 api 密钥来做，我不能用服务器端的 OAuth 来做。 这是破解谷歌播放订阅的方法吗？
