javascript - Google Maps API - 折线捕捉到道路限制

Question

我正在构建几条与道路对齐的折线。下面是其中 2 个的代码。超过 15 条折线捕捉到道路，出现以下错误:“方向请求失败:OVER_QUERY_LIMIT”。

因此，我想找到一个解决方案。其中之一就是将所有这些信息放入我的计算机的缓存中，因此我从 Google map 中获得的唯一内容就是 map 。这可能吗？

您还知道其他一些解决方案吗？

//Circuit CHL1C1

CHL1C1 = [
    new google.maps.LatLng(-22.91401,-68.192237),
    new google.maps.LatLng(-23.226361,-67.064938)
    ];

var traceCHL1C1 = new google.maps.Polyline({
    path: CHL1C1,
    strokeColor: "red",
    strokeOpacity: 1.0,
    strokeWeight: 4
});

var serviceCHL1C1 = new google.maps.DirectionsService(),traceCHL1C1,snap_pathCHL1C1=[];
traceCHL1C1.setMap(map);
for(j=0;j<CHL1C1.length-1;j++){
    serviceCHL1C1.route({origin: CHL1C1[j],destination: CHL1C1[j+1],travelMode: google.maps.DirectionsTravelMode.DRIVING},function(result, status) {
        if(status == google.maps.DirectionsStatus.OK) {
            snap_pathCHL1C1 = snap_pathCHL1C1.concat(result.routes[0].overview_path);
            traceCHL1C1.setPath(snap_pathCHL1C1);
        } else alert("Directions request failed: "+status);        
    });
}




//Circuit CHL1C2

CHL1C2 = [
    new google.maps.LatLng(-22.898988,-68.198154),
    new google.maps.LatLng(-22.337195,-68.016747),
    new google.maps.LatLng(-22.443062,-68.899408)
];

var traceCHL1C2 = new google.maps.Polyline({
    path: CHL1C2,
    strokeColor: "green",
    strokeOpacity: 1.0,
    strokeWeight: 4
});

var serviceCHL1C2 = new google.maps.DirectionsService(),traceCHL1C2,snap_pathCHL1C2=[];
traceCHL1C2.setMap(map);
for(j=0;j<CHL1C2.length-1;j++){
    serviceCHL1C2.route({origin: CHL1C2[j],destination: CHL1C2[j+1],travelMode: google.maps.DirectionsTravelMode.DRIVING},function(result, status) {
        if(status == google.maps.DirectionsStatus.OK) {
            snap_pathCHL1C2 = snap_pathCHL1C2.concat(result.routes[0].overview_path);
            traceCHL1C2.setPath(snap_pathCHL1C2);
        } else alert("Directions request failed: "+status);        
    });
}

如果我错了，请纠正我，但免费 API 最多有 8 个航路点。
