Question

我在新的Here Routing API 7.2中遇到了这个烦人的问题：

如果我想使用2个以上的航点（0和1），我会从服务器收到错误：

请求：

https://route.api.here.com/routing/7.2/calculateroute.xml?waypoint0=55.67395%2C12.41686&waypoint1=55.6452%2C12.52621&waypoint2=55.9552%2C12.52421&mode=fastest%3Bcar%3Btraffic:disabled%3BboatFerry:-1&language=en_US&verbosemode=0&alternatives=1&app_code=XXXXXX&app_id=XXXXXXXXXX&routeattributes=wp,sm,sc,sh,bb,lg,no

错误回应：

<ns2:Error xmlns:ns2="http://www.navteq.com/lbsp/Routing-Errors/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" type="ApplicationError" subtype="NoRouteFound" xsi:type="ns2:RoutingServiceErrorType">

</ns2:Error>

如果我带走了上面的waypoin2请求，那就好了：

请求：

https://route.api.here.com/routing/7.2/calculateroute.xml?waypoint0=55.67395%2C12.41686&waypoint1=55.6452%2C12.52621&mode=fastest%3Bcar%3Btraffic:disabled%3BboatFerry:-1&language=en_US&verbosemode=0&alternatives=1&&app_code=XXXXXXXXXX&app_id=XXXXXXXXXX&routeattributes=wp,sm,sc,sh,bb,lg,no,legs

OK RESPONSE：

为什么它不适用于2个航路点？这对我来说看起来像一个大胖子，但我无法在here.com或互联网上的任何地方找到任何关于它的信息...... :(（

此请求中包含3个航路点，旧版本6.2：

请有人帮我解决这个问题吗？

Answer 1

路由AP I作为单个路径不支持组合使用点（使用waypoint2参数）和备用路由（使用alternatives参数）请求。

路由API 引用声明：

alternatives

将计算的最大替代路线数量   回。替代路线可能无法使用，因此它们不可用   保证退回。如果在a中使用至少一个通孔点   路径请求，不支持返回备用路由。

所以你可以找到：

单 route from A to B to C或
多个备用路线A至B，没有中间航路点。

当然，如果您提出两个单独的请求，您可以找到：

A到B的替代路线然后
B to C with alternative routes

尝试在新的Here Routing API 7.2中使用2个以上的航点时出错
