Google地图：DirectionService会返回OVER_QUERY_LIMIT响应 [英] Google maps: DirectionService returns OVER_QUERY_LIMIT response

问题描述

我使用google.maps.DirectionsService获取两点之间的路线。该代码在过去的8个月内运行。但是，从过去的几天，DirectionService路由调用正在返回OVER_QUERY_LIMIT响应状态。只有6组点，其中只有2或3个请求得到结果，其余都失败。代码与过去8个月保持一致。以下是供参考的代码片段：

  var directionsService = new google.maps.DirectionsService（）; 
 var request = {
 origin：originLatlng，//这是类型：google.maps.LatLng 
 destination：destLatlng，
 travelMode：google.maps.DirectionsTravelMode.DRIVING， 
 provideRouteAlternatives：true 
}; 
 
 directionsService.route（request，function（result，status）{
 if（status == google.maps.DirectionsStatus.OK）{
 
 polyline = new google.maps.Polyline（{
 path：result.routes [0] .overview_path，
 strokeColor：color1，
 strokeOpacity：0.8，
 strokeWeight：5，
 geodesic：true 
}）; 
} 
} 
  

几乎6个这样的同步请求发给了方向服务，我不能在这些请求之间进行睡眠，因为它会增加我的应用程序GUI加载时间。

我尝试了相同的代码不同的网络也依然存在，仍然存在问题。

我绝对没有接近达到2500个每日要求限额。

这里可能是什么问题？租赁建议为此解决方案。

任何帮助将不胜感激。

预先致谢

Google Map API有两种配额。您正在使用客户端配额，如果您请求的每分钟地理编码超过〜20（这是我观察到的），则会阻止您。

I am using google.maps.DirectionsService for getting the route between two points. This code was working from past 8 months. However, from past couple of days DirectionService route call is returning OVER_QUERY_LIMIT response status. There are only 6 set of points, out of which only 2 or 3 requests are getting the result, rest are failing. Code is unchanged from past 8 months. Below is the code snippet for reference:

            var directionsService = new google.maps.DirectionsService();
            var request = {                     
                    origin:originLatlng, //This is of type : google.maps.LatLng
                    destination:destLatlng,
                    travelMode: google.maps.DirectionsTravelMode.DRIVING,
                    provideRouteAlternatives: true
            };

            directionsService.route(request, function(result, status) {
                if (status == google.maps.DirectionsStatus.OK) {

                    polyline = new google.maps.Polyline({
                        path: result.routes[0].overview_path,
                        strokeColor: color1,
                        strokeOpacity: 0.8,
                        strokeWeight: 5,
                        geodesic: true
                    });
                }
            }

Almost 6 such simultaneous requests are made to DirectionService. I cannot put sleep in between the requests because, it will increase my application GUI load time.

I have tried the same code from different networks also, still problem persists.

I definitely did not come anywhere close to reaching the 2,500 daily request limit.

What could be the problem here? Please suggest a solution for this.

Any help would be greatly appreciated.

Thanks in advance

There are 2 kind of quota for Google Map API. You are using client side quota which blocks you if you request more than ~20 ( thats my observation ) geocode per minute.

Look here for detailed information :
