谷歌地图API版本的差异 [英] Google Maps API Version difference

问题描述

我想展现两地之间的路径，我想用谷歌的地方API V3 路由两点之间的步骤。

---

在我使用老谷歌地图API ，并按照要求提供了完美的结果：

<$p$p><$c$c>http://maps.google.com/maps?f=d&hl=en&saddr=19.5217608,-99.2615823&daddr=19.531224,-99.248262&ie=UTF8&0&om=0&output=kml

输出：

---

现在我尝试用新的谷歌地图API替换此，并按照要求提供了错误的结果，在这两种情况下，我使用相同的源和目的，但结果给了谷歌地图上不同的行为：

<$p$p><$c$c>http://maps.googleapis.com/maps/api/directions/json?origin=19.5217608,-99.2615823&destination=19.531224,-99.248262&sensor=false

我的问题是，新的谷歌地图API返回的源和目标，因此该路径没有显示在谷歌地图完美的步数少。

请帮忙解决这个问题的新的谷歌地图API V3。

在此先感谢。

解决方案

有什么新的谷歌地图API V3？
谷歌地图路线API第3版为Android提供了恩codeD折线算法格式的路线。

我们必须要做的？
我们必须得去code这个折线显示精确的地图

我们如何去code此连接由谷歌路线API第3版提供了codeD折线？
请参考这三个环节有连接从谷歌地图路线API第3版codeD折线回报

I'm trying to show route between two places, I want to used Google Places API V3 for route steps between two points.

Before I was using Old Google Maps API, and following request gives perfect result:

http://maps.google.com/maps?f=d&hl=en&saddr=19.5217608,-99.2615823&daddr=19.531224,-99.248262&ie=UTF8&0&om=0&output=kml

Output :

Now I try to replace this with New Google Maps API, and following request gives wrong result, In both case i'm using same source and destination, but result gives different behavior on Google Map:

http://maps.googleapis.com/maps/api/directions/json?origin=19.5217608,-99.2615823&destination=19.531224,-99.248262&sensor=false

My problem is that, New Google Maps API return less number of steps between source and destination therefore the route not showing perfect on Google Map.

Please help to resolve this problem for New Google Maps API v3.

Thanks in advance.
