 取得的运动轨迹数据可以参考示例文件： [single_log_20130817.json](single_log_20130817.json)。这个轨迹是跟着绿野去长峪城腐败的轨迹。：D，摆两张照片放放毒。

 ### GPX文件输出 ###
 
 Python 中有直接写 GPX 格式文件的包： [gpxpy](https://github.com/tkrajina/gpxpy) 。 用来创建 GPX 文件非常容易。函数中的参数 route 是 get\_single\_log 的结果。不过在使用中，如果将时间数据写入 GPX 文件时，gpxpy有个小Bug，需要对时间格式处理的部分做个小调整。

+### Track 和 Route ###
+
+新浪微博网友 @齐亮-Cavendish 发现如上文生成的 GPX 文件，没法导入 heiaheia.com , 经过检查，发现 heiaheia 只能够导入 Track 格式的 GPX 文件。
+
+因此修改 GPX 输出代码如下，增加参数对导出格式的限定。

+
+        # print 'Created GPX:', gpx.to_xml()
+        return gpx.to_xml()
+
+使用 Track 格式的 GPX 文件，能够将数据导入 Heiaheia 网站，能够正确显示轨迹、里程、以及时长。
+
+但是，还有一个问题，文件中Track记录为8月份的数据，并没有被自动放到8月份去，而是放在了当前 Walk 创建时所设定的日期：10月8日。
