Question

我有代码：

    orig_lat = 48.864716  # Paris lat
    orig_lon = 2.349014  # Paris lon
    dest_lat = 52.518623
    dest_lon = 13.376198

    google_url = 'http://maps.googleapis.com/maps/api/'
    fn_url = 'distancematrix/'
    opt_url = '&language=en-EN&sensor=false'

    url = "%s%sjson?origins=%s,%s&destinations=%s,%s&mode=driving%s" % (
        google_url, fn_url, str(orig_lat), str(orig_lon),
        str(dest_lat), str(dest_lon), opt_url
    )

    ret = requests.get(url)

和谷歌回复：

{
    "destination_addresses" : [ "Paul-Löbe-Allee, 10557 Berlin, Germany" ],
    "origin_addresses" : [ "18bis Rue Tiquetonne, 75002 Paris, France" ],
    "rows" : [
         {
            "elements" : [
                {
                    "distance" : {
                        "text" : "1,045 km",
                        "value" : 1045157
                    },
                    "duration" : {
                        "text" : "9 hours 58 mins",
                        "value" : 35905
                    },
                    "status" : "OK"
                }
            ]
        }
   ],
   "status" : "OK"
}

但我有一个目的地点和许多原点：

dest_lat = 52.518623
dest_lon = 13.376198

origins = [
    (48.864716, 2.349014),  # Paris
    (40.415363, -3.707398),  # Madrid
    (52.237049, 21.017532)  # Warsaw
]

我希望在一个请求中获得所有持续时间和距离。这可能吗？

正如geocodezip所指出的，这是距离矩阵的标准特征。

http://maps.googleapis.com/maps/api/distancematrix/json?origins=48.864716,2.349014|40.415363,-3.707398|52.237049,21.017532&destinations=52.518623,13.376198&key=YOUR_API_KEY

如何从多个地点到目的地的距离？
