Google Map - 距離矩陣API - 結果順序

關於Google Map - 距離矩陣API。結果是否會保證在同一個訂單中有要求？如果我要求API獲取從一個起始點到多個目標點的距離，結果排序是否能保證與請求的順序相匹配？Google Map - 距離矩陣API - 結果順序

我需要將我的業務對象映射到API調用的結果，我找不到硬映射他們。只有訂單縫適合。

感謝您的輸入。

距離矩陣API的Web服務返回結果作爲rows陣列，其中每一行項目對應於一個來源從origins參數在請求和所述順序被保存在原始請求。每個行項目包含elements數組，其中每個元素對應於請求中參數destinations中的一個目標，並且順序也被保留。

你可以看看官方文檔在距離矩陣API響應結構進行了說明：

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

希望這有助於！

1）結果如果是JSON響應，它將採用相同的格式。實施例：a.Single響應：

{ 
    "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" 
}

灣多重響應：

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

      }, 
      { 
       "distance": {

        "value": 21296 
       }, 
       "duration": { 
        "text": "34 mins", 
        "value": 2058 
       }, 
       "status": "OK" 
      }, 
      { 
       "distance": { 
        "text": "2.9 mi", 
        "value": 4662 
       }, 
       "duration": { 
        "text": "18 mins", 
        "value": 1086 
       }, 
       "status": "OK" 
      }, 
      { 
       "distance": { 
        "text": "8.5 mi", 
        "value": 13738 
       }, 
       "duration": { 
        "text": "23 mins", 
        "value": 1367 
       }, 
       "status": "OK" 
      }, 
      { 
       "distance": { 
        "text": "15.9 mi", 
        "value": 25544 
       }, 
       "duration": { 
        "text": "29 mins", 
        "value": 1755 
       }, 
       "status": "OK" 
      }, 
      { 
       "distance": { 
        "text": "13.2 mi", 
        "value": 21296 
       }, 
       "duration": { 
        "text": "34 mins", 
        "value": 2058 
       }, 
       "status": "OK" 
      } 
     ] 
    } 
], 
"status": "OK" 
}

2）我認爲上面的例子應該照顧第二個問題。

3）同.NET對象的結果JSON可以容易地mapped.Here在下面映射類

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; } 
     } 
    }

希望這有助於:)
