整合傳單GeoJSON的對象爲Elasticsearch Geoshape查詢在AngularJs

Question

我有是在表面上如下本地ES實例運行geoshape查詢：

httprequest.js與geoshape查詢

spatialsearch() { 
       var _url = 'http://127.0.0.1:9201/_search?'; 

       var b = { 
        "query": { 
         "bool": { 
          "must": { 
           "match_all": {} 
          }, 
          "filter": { 
           "geo_shape": { 
            "metadata.o2r.spatial.geometry": { 
             "shape": { 
              "type": "polygon", 
              "coordinates": [ 
               [ 
                [-22.0, 76.0], 
                [-27.0, 65.0], 
                [-57.0, 65.0], 
                [-59.0, 76.0], 
                [-22.0, 76.0] 
               ] 
              ] 
             }, 
             "relation": "contains" 
            } 
           } 
          } 
         } 
        } 
       }; 
       return $http.post(_url, b); 
       console.log("hello"); 

      } 

目前我硬編碼的查詢座標，但我希望能夠從用戶在小葉地圖上繪製的geojson對象中獲取座標，並將它們插入到上述函數中的座標數組中。我能夠在開發控制檯中以字符串形式顯示geojson對象的座標，但是我找不到如何保存它們並在上述函數中檢索它們。 這是我如何製作geojson並在控制檯中顯示它們的座標。

search.controller.js

leafletData.getMap().then(function(map) { 

       leafletData.getLayers().then(function(baselayers) { 
       var drawnItems = baselayers.overlays.draw; 

        map.on('draw:created', function (e) { 

        var layer = e.layer; 

        drawnItems.addLayer(layer); 

        console.log(JSON.stringify(layer.toGeoJSON())); 
        }); 
       }); 

      });

我存儲在變量中的座標，然後把它稱爲在HTTP請求功能coordinates_selected = layer.toGeoJSON();

更新功能

function spatialsearch(coordinates_selected) { 
    var coords = coordinates_selected.geometry.coordinates; 
    console.log('c', JSON.stringify(coordinates_selected.geometry.coordinates)); 
    var _url = 'http://localhost:9201/_search?'; 

    var b = { 
    "query": { 
     "bool": { 
     "must": { 
      "match_all": {} 
     }, 
     "filter": { 
      "geo_shape": { 
      "metadata.o2r.spatial.geometry": { 
       "shape": { 
       "type": "polygon", 
       "coordinates": coords 

       /* [ 
        [-22.0, 76.0], 
        [-27.0, 65.0], 
        [-57.0, 65.0], 
        [-59.0, 76.0], 
        [-22.0, 76.0] 
        ]*/ 

       }, 
       "relation": "within" 
      } 
      } 
     } 
     } 
    } 
    };
