HERE API Fleet Telematrics 搜索超时问题

Question

''由于搜索超时，无法到达航路点 61''

我正在使用 ;sort 通过 66 个航路点（全部在一个城市）以获得优化的路线。但是 6 个坐标会导致这个问题。如果我删除这 6 个坐标，我会得到路线。但有趣的是，如果我将这 6 个坐标与其他几个坐标（少于 15-20 个）一起使用，它也会返回路线。但是，如果我将这 6 个中的至少一个与所有其他人一起使用，那么我就会遇到这个问题。此外，所有坐标都是真实的，靠近道路，真实地址。 有没有人有类似的经历，或者有没有人对此问题有一些提示或解决方案？

Answer 1

由于您在 Fleet Telematics API 正常计算路线请求中使用排序模式，因此超时时间为 50 - 60 秒。此外，您在排序模式下使用多达 90 个航路点，这在严格超时的情况下计算非常昂贵。所以可以预料到计算会超时。

请使用 Waypoint Sequence Extension API，它有更高的超时时间和不同的算法。
