java - 向 google map api 方向发出带有航点的 http 请求

Question

如何解决这个问题。

https://maps.googleapis.com/maps/api/directions/json?origin=17.3916642,78.4346606&destination=78.4382585808635,17.3813395082035&%20waypoints=optimize:true|17.3916642,78.4346606|17.3865225743848,78.4374928101897|17.3813395082035,78.4382585808635&sensor=false

这是我得到的答案:

 {"geocoded_waypoints" : [ {}, {} ],
       "routes" : [],
       "status" : "ZERO_RESULTS"}

有人可以帮助我理解出了什么问题吗？我的请求是否有错误，或者我绕过了 google map api 方向的限制？

您是否翻转了目的地的纬度和经度？ 通过此链接，它可以工作(我将它们翻转回来):https://maps.googleapis.com/maps/api/directions/json?origin=17.3916642,78.4346606&destination=17.3813395082035,78.4382585808635&%20waypoints=optimize:true|17.3916642,78.4346606|17.3865225743848,78.4374928101897|17.3813395082035,78.4382585808635&sensor=false

编辑 路径点前面有一个 %20 (urlencoded 空格)，删除后得到: https://maps.googleapis.com/maps/api/directions/json?origin=17.3916642,78.4346606&destination=17.3813395082035,78.4382585808635&waypoints=optimize:true%7C17.3916642,78.4346606%7C17.3865225743848,78.4374928101897%7C17.3813395082035,78.4382585808635&sensor=false
