如何在Mapbox Android中获取路线的原始Json数据

问题描述

如何获取原始数据，如android MapboxDocsLink中的此链接所示

我想使用这些数据每小时获取直到目的地的坐标点

解决方法

对于Android，请参见https://docs.mapbox.com/android/java/examples/show-directions-on-a-map

在onResponse()内：https://github.com/mapbox/mapbox-android-demo/blob/master/MapboxAndroidDemo/src/main/java/com/mapbox/mapboxandroiddemo/examples/javaservices/DirectionsActivity.java#L156

这将打印出响应的json：Log.d("DirectionsActivity","response.body().toJson(); = " + response.body().toJson());

Android Studio logcat具有最大字符数限制，这就是为什么整个路由JSON可能不在logcat中的原因（例如下面的JSON代码段中）。 https://gist.github.com/kiirpi/7747423是如何打印完整内容的方法。在此要点中，将sb替换为response.body().toJson()。
