关于谷歌地图-距离矩阵API。结果会是保证在同一顺序有要求吗?

我需要将我的业务对象映射到API调用的结果,但我找不到方法 硬地图

谢谢你的意见。

1) 如果是JSON响应,结果将是相同的格式。

{
    "destination_addresses": [
      "Karnataka, India"
    ],
    "origin_addresses": [
       "Delhi, India"
    ],
    "rows": [
       {
           "elements": [
               {
                   "distance": {
                       "text": "1,942 km",
                       "value": 1941907
                   },
                   "duration": {
                       "text": "1 day 9 hours",
                       "value": 120420
                   },
                   "status": "OK"
               }
           ]
       }
   ],
   "status": "OK"
}

b、多重响应:

{
    "destination_addresses": [
    "67-89 Pacific St, Brooklyn, NY 11201, USA",
    "67-89 Pacific St, Brooklyn, NY 11201, USA",

],
"origin_addresses": [

],
"rows": [

                "status": "OK"
            },
            {

                "status": "OK"
            },
            {
                "distance": {
                    "text": "2.9 mi",
                    "value": 4662
                },
                "duration": {

                "status": "OK"
            },
            {

                    "value": 1367

            {

                    "text": "15.9 mi",
                    "value": 25544
                },
                "duration": {
                    "text": "29 mins",
                    "value": 1755
                },
                "status": "OK"
            },
            {
                "distance": {
                    "text": "13.2 mi",
                    "value": 21296

                    "value": 2058
                },
                "status": "OK"
            }
        ]
    }
],
"status": "OK"
}

2) 我认为上面的例子也应该考虑第二个问题。

3) 与。NET对象。结果JSON可以轻松映射。下面是映射的类

public class Response
    {
        public string Status { get; set; }

        [JsonProperty(PropertyName = "destination_addresses")]
        public string[] DestinationAddresses { get; set; }

        [JsonProperty(PropertyName = "origin_addresses")]
        public string[] OriginAddresses { get; set; }

        public Row[] Rows { get; set; }

        public class Data
        {
            public int Value { get; set; }
            public string Text { get; set; }
        }

        public class Element
        {
            public string Status { get; set; }
            public Data Duration { get; set; }
            public Data Distance { get; set; }
        }

        public class Row
        {
            public Element[] Elements { get; set; }
        }
    }

距离矩阵API web服务将结果返回为 rows 每个行项目对应于一个原点的数组 origins 参数,并且顺序与原始请求中相同。每行项目包含 elements 每个元素对应一个目标的数组 destinations

您可以查看官方文档,其中解释了距离矩阵API响应结构:

https://developers.google.com/maps/documentation/distance-matrix/intro#DistanceMatrixResponses

希望这有帮助!
