IAP收据验证权限已拒绝

Question

我意识到不久前还会出现类似的问题，但是我已经完成了解决这些问题的步骤。我正在尝试通过网络应用使用Google Play IAP验证端点（androidpublisher.inapppurchases.get）。我在关联的Google API控制台帐户中创建了一个服务帐户（请确保为“所有者”角色提供权限），并授予该用户“管理员”对Play商店帐户的访问权限，并且正在使用下载的密钥来获取访问令牌

请求：

GET https://www.googleapis.com/androidpublisher/v3/applications/#{package_name}/purchases/products/#{product_id}/tokens/#{token}
Authorization: Bearer #{access_token}

响应：

{
 "error": {
  "errors": [
   {
    "domain": "androidpublisher",
    "reason": "permissionDenied",
    "message": "The current user has insufficient permissions to perform the requested operation."
   }
  ],
  "code": 401,
  "message": "The current user has insufficient permissions to perform the requested operation."
 }
}

作为健全性检查，请求tokeninfo返回该服务帐户的预期用户ID：

GET https://www.googleapis.com/oauth2/v3/tokeninfo
Authorization: Bearer #{access_token}

响应：

{
  "azp": "#{service_account_unique_id}",
  "aud": "#{service_account_unique_id}",
  "scope": "https://www.googleapis.com/auth/androidpublisher",
  "exp": "1544468156",
  "expires_in": "3600",
  "access_type": "offline"
}
