您可以通过超过谷歌地图API的Web服务使用限制

 每天发送太多的要求。发送请求过快，每秒即太多的请求。发送请求过快过久或滥用Web服务。超过其他使用限制，例如每高程API请求中百分点。 

在接收到状态code OVER_QUERY_LIMIT的回应，您的应用程序应该确定哪些使用限制已经被超过。这可以通过暂停2秒和重新发送相同的请求来完成。如果状态code仍然是OVER_QUERY_LIMIT，您的应用程序每天发送太多的请求。否则，你的应用程序每秒发送过多的请求。

You can exceed the Google Maps API Web Services usage limits by:

Sending too many requests per day.
Sending requests too fast, i.e. too many requests per second.
Sending requests too fast for too long or otherwise abusing the web service.
Exceeding other usage limits, e.g. points per request in the Elevation API.

Upon receiving a response with status code OVER_QUERY_LIMIT, your application should determine which usage limit has been exceeded. This can be done by pausing for 2 seconds and resending the same request. If status code is still OVER_QUERY_LIMIT, your application is sending too many requests per day. Otherwise, your application is sending too many requests per second.
