google-app-engine - Google Calendar api - 超出速率限制(即使不是)

Question

我有一个可与各种 Google API 配合使用的 App Engine 应用程序。我启动了一个同步任务，将 3000 个事件同步到各种用户日历。它工作了一段时间，但现在我收到以下错误:

PHP Fatal error:  Uncaught exception 'Google_Service_Exception' with message '{
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "rateLimitExceeded",
    "message": "Rate Limit Exceeded"
   }
  ],
  "code": 403,
  "message": "Rate Limit Exceeded"
 }
}

如果我查看 Api 仪表板，限制真的很高:

每天查询 1,000,000
每个用户每 100 秒的查询数 50,000,000。

我怎样才能克服这个错误？我希望完成此任务，以便用户在他们的日历中看到事件。

如 documentaion 中所述用户速率限制是防洪。应用程序每秒只能发出 X 次请求。

403: Rate Limit Exceeded The per-user limit from the Developer Console has been reached.

    {
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "rateLimitExceeded",
    "message": "Rate Limit Exceeded"
   }
  ],
  "code": 403,
  "message": "Rate Limit Exceeded"
 }
}

建议的操作:

使用exponential backoff .

您可以尝试添加配额用户，这有时会有所帮助。

quotaUser An arbitrary string that uniquely identifies a user.
Lets you enforce per-user quotas from a server-side application even in cases when the user's IP address is unknown. This can occur, for example, with applications that run cron jobs on App Engine on a user's behalf. You can choose any arbitrary string that uniquely identifies a user, but it is limited to 40 characters.

如果您收到配额错误，那么即使您认为没有超出配额，它也已超出。无法增加应用程序级别配额。你唯一能做的就是放慢速度。
