ios - 谷歌路线不返回优化路线

Question

我有一个应用程序，可以让用户使用起点/目的地点及其间的航路点生成路线。如果我提交的网址没有optimized:true，我会得到一条折线，该折线按照发送的顺序到达每个航路点。

如果我将optimized:true添加到查询中，那么在这种情况下，我的第二个路径点(zero_results)会出现错误，这会导致应用程序崩溃。在这两次提交中，我都发送了每个航路点的地址城市、邮政编码。

我的初始网址(已解码)如下所示:

https://maps.googleapis.com/maps/api/directions/json?origin=115 E Main St, Monrovia, IN 46157, USA&destination=115 E Main St, Monrovia, IN 46157, USA&waypoints=234 E SOUTHERN AVE INDIANAPOLIS, IN 46225|208 MEADOW DR DANVILLE, IN 46122|485 N INDIANA AVE SELLERSBURG, IN 47172|1111 RONALD REAGAN PKWY STE C1400 AVON, IN 46123|651 S CLARIZZ BLVD BLOOMINGTON, IN 47401&key=KEY GOES HERE

部分 JSON 返回:

         "geocoder_status" : "OK",
         "place_id" : "ChIJXZBHhT-WbIgRPl_LqYqD4hc",
         "types" : [ "street_address" ]

   ],

我的优化网址如下所示:

   "routes" : [],

我不太确定我在这里做错了什么。

Answer 1

您应该传递 optimize:true 而不是 optimized:true

这是我比较您提供的 2 个网址时的工作网址。
