Question

我有一个geoshape查询，它运行在本地ES实例上，如下所示：

带有地理位置查询的

httprequest.js

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");

            }

目前我已将坐标硬编码到查询中，但我希望能够从用户在传单地图上绘制的geojson对象中获取坐标，并将它们插入上述函数中的坐标数组中。我能够在开发控制台中以字符串形式显示geojson对象的坐标，但我无法弄清楚如何保存它们并在上面的函数中检索它们。这是我如何制作geojson并在控制台中显示它们的坐标。

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()));
                  });
               });

           });

我将坐标存储在变量中，然后在http请求函数coordinates_selected = layer.toGeoJSON();

中调用它

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"
            }
          }
        }
      }
    }
  };

将Leaflet Geojson对象集成到AngularJs中的Elasticsearch Geoshape查询中
