我如何获取所有行车方式（例如行车，公交，骑车，步行）的距离和时长，并将其存储在数据库中

Question

我只成功显示和存储单个出行方式的数据，但现在我想存储所有出行方式的距离和持续时间之类的数据，这是代码，我需要执行哪些更改，请提前感谢mapper.html

Answer 1

在您的请求中将MODE更改为Walking，Transit，Bicycling。首先使用浏览器上的Google Directions API端点检查输出。 步行和骑车的结果不适用于每对地点。

在travelMode的最后部分附加：google.maps.TravelMode。“在此处更改”。 在此处输入链接描述。如果不可能进行迭代（循环），请重复三次代码。
