向Google发送的HTTP请求通过航点映射api方向

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|17.38133950820635,7

这是我得到的答案：

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

可以帮助我了解问题所在吗？ 我的请求是否有错误，或者我绕过了google maps api方向的限制？

您是否在目的地上颠倒了经纬度？ 通过此链接，它可以工作（我将它们向后翻转）： 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

编辑删除后，航路点前有%20 （加密码的空间）： https ://maps.googleapis.com/maps/api/directions/json?origin=17.3916642,78.4346606&destination=17.3813395082035,78.4382585808635&waypoints =优化：true％7C17.3916642,78.4346606％7C17.3865225743848,78.4374928101897％7C17.3813395082035,78.4382585808635＆sensor = false
