            }
          ]
        }
      ]
    }
  ]
}

但是这些回复并未提供我可以在我的网站上显示的往返地点信息.

But these response does not provide a from and to location information which I can show in my website.

1. 还有其他我可以用来获取位置信息的dataTypeName吗?

显示的边界框数据是什么?可以通过任何方式显示位置吗?

What is the bounding box data shown? Is it useful in any way to show location?

"dataTypeName": "com.google.distance.delta"提供的数据是什么意思?是起点和终点之间的距离吗?

What is the data provided by "dataTypeName": "com.google.distance.delta" mean? Is it the distance between start and end location?

推荐答案

位置数据只能由写入该数据的应用读取.您的应用只能读取其写入的数据.它无法读取由其写入的位置示例数据其他应用." 来自developers.google.com

"Location data can only be read by the app that wrote the data. Your app can only read back data it wrote. It cannot read location sample data written by other apps." from developers.google.com
