Question

我正在尝试使用2个地址之间的bing maps api来获取汽车的行驶距离。

到目前为止，我已经获得了返回带有数据的JSON文件的链接，但是不确定如何获取；设置；结果存入基本类变量。

链接：var url =“ http://dev.virtualearth.net/REST/V1/Routes/Driving?wp.0=11+streetname+parish+city+Postcode&wp.1=3+DestinationStreet+DestinationParish+DestinationPostcode&optimizeWaypoints=true&distanceUnit=mi&key=我的BING API密钥

这将返回以下JSON（仅一部分）：
