为什么结果roadApi是不同的＆＃34;如何得到＆＃34;在google.maps上？

Question

我在＆＃34; road api＆＃34;上的两点之间尝试折线。我回答：＆＃34; warningMessage：＆＃34;输入路径太稀疏。您应该提供连续点彼此靠近的路径。请参阅＆＃39;路径＆＃39; Google Roads API文档中的参数。＆＃34;＆＃34;

但如果我在https://www.google.com.ua/maps/dir/%D0%94%D0%BD%D0%B8%D0%BF%D1%80%D0%BE,+%D0%94%D0%BD%D0%B5%D0%BF%D1%80%D0%BE%D0%BF%D0%B5%D1%82%D1%80%D0%BE%D0%B2%D1%81%D0%BA%D0%B0%D1%8F+%D0%BE%D0%B1%D0%BB%D0%B0%D1%81%D1%82%D1%8C/%D0%97%D0%B0%D0%BF%D0%BE%D1%80%D0%BE%D0%B6%D1%8C%D0%B5,+%D0%97%D0%B0%D0%BF%D0%BE%D1%80%D0%BE%D0%B6%D1%81%D0%BA%D0%B0%D1%8F+%D0%BE%D0%B1%D0%BB%D0%B0%D1%81%D1%82%D1%8C/@48.1444745,34.1118762,8z/data=!3m1!4b1!4m13!4m12!1m5!1m1!1s0x40dbe303fd08468f:0xa1cf3d5f2c11aba!2m2!1d35.046183!2d48.464717!1m5!1m1!1s0x40dc673dfa85bb03:0x7e675cd9074d3f4a!2m2!1d35.139567!2d47.8388?hl=ru

做同样的事情

结果很棒，我可以像google.com/maps那样做。

您必须使用Directions API代替Roads API才能获得两点之间的路线。

请求类似于

https://maps.googleapis.com/maps/api/directions/json?origin=%D0%94%D0%BD%D0%B8%D0%BF%D1%80%D0%BE%2C%20%D0%94%D0%BD%D0%B5%D0%BF%D1%80%D0%BE%D0%BF%D0%B5%D1%82%D1%80%D0%BE%D0%B2%D1%81%D0%BA%D0%B0%D1%8F%20%D0%BE%D0%B1%D0%BB%D0%B0%D1%81%D1%82%D1%8C%2C%20%D0%A3%D0%BA%D1%80%D0%B0%D0%B8%D0%BD%D0%B0%2C%2049000&destination=%D0%97%D0%B0%D0%BF%D0%BE%D1%80%D0%BE%D0%B6%D1%8C%D0%B5%2C%20%D0%97%D0%B0%D0%BF%D0%BE%D1%80%D0%BE%D0%B6%D1%81%D0%BA%D0%B0%D1%8F%20%D0%BE%D0%B1%D0%BB%D0%B0%D1%81%D1%82%D1%8C%2C%20%D0%A3%D0%BA%D1%80%D0%B0%D0%B8%D0%BD%D0%B0%2C%2069061&key=YOUR_API_KEY

您还可以在路线计算器中看到此结果：

我希望这有帮助！
