我尝试使用Google Directions API生成路线。生成路线不是问题，而是 我想通过在9小时或（32.400秒）内限制路线来加载路线点
我尝试将其放入While（循环）中，该过程计算时间但处理Directions API时出错（查询超限） 有没有人有任何想法？

答案 0 :(得分：0)
我没看完，但是：
// Load Waypoints.
while (i < 20)
...
无法工作，因为方向服务在一个请求中限制为8个航点。因此，您必须在达到此限制后开始新请求，或者您从点到点请求。如果你在这里搜索＆＃34;多个航路点＆＃34;你会找到很多解决方案的例子。
答案 1 :(得分：0)
当我在调用DirectionsService之前加载Waypoints时，路由处理没有错误，但时间远远高于我的业务规则。
我知道DirectionsService最多限制为23个航路点。
我的问题是：加载航点，检查时间，加载另一个航路点并再次检查时间，直到时间等于32000秒
// Load Waypoints.
while (i < 20) {
waypts.push({ location: customers[i].endereco, stopover: true });
i++;
}
