谷歌的http请求用路标映射api方向

Question

如何解决此问题。

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"}

可以帮我理解错误吗？我的请求是否有错误，或者我是否绕过google maps api方向的限制？

您是否在目的地上翻转纬度和经度？ 通过此链接，它可以工作（我将它们翻回）：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

修改 在航路点前面有一个%20（urlencoded空间），移除后你得到： 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
