fitness.course对象无法在facebook上绘制路径

Question

我试着开发一个具有分享功能的应用程序，在facebook上画出一条健身路线。我认为为了在地图上画出路线，所有的事情都已经涵盖了。

我的问题是

1. 什么类型的度量属性，我需要画出正确的路线，如耐克运行？
2. 是否有某种顺序来列出位置值的元数据？

Answer 1

我自己找到答案了。

在facebook地图上绘制路线(？)每个活动数据点必须有位置(lat、long)、距离(值、单位)、速度(值、单位)。因为你的骑行，跑步和任何课程通常都有很多的地理点，你最好有一个单独的元数据页面为课程。Facebook实际上是推荐的。这也是非常重要的使用适当的单位，但有时你找不到一个。然后用米/秒代替时速。Facebook会处理一些事情，用每小时一小时的速度来展示价值。

我附上了下面的示例代码。希望它能帮助像我这样的人。

课程对象HTML

<meta property="og:description" content="ABC's burned 0 kcal for 3m 30s. The best speed was 0.0. " />

GEOPOINT对象(rel=“开图”)

<meta property="fitness:metrics:pace:units" content="s/m" />

Answer 2

这是个老生常谈的问题，但对于寻求解决办法的人来说：

您应该为每个点添加适应度:度量:时间戳属性，以查看路由：

<!-- ActivityDataPoint 0 -->
<meta property="fitness:metrics:location:latitude" content="37.51844" />
<meta property="fitness:metrics:location:longitude" content="126.9918" />
<meta property="fitness:metrics:location:altitude" content="16.61127" />
<meta property="fitness:metrics:timestamp" content="2011-01-26T00:00" />

<!-- ActivityDataPoint 1 -->
<meta property="fitness:metrics:location:latitude" content="37.51769" />
<meta property="fitness:metrics:location:longitude" content="126.9908" />
<meta property="fitness:metrics:location:altitude" content="13.85767" />
<meta property="fitness:metrics:timestamp" content="2011-01-26T00:30" />
