使用ArcGIS Javascript API從Geoserver的WMS圖層添加要素表

Question

我想知道我想做的事是否可能。 我試圖將功能表添加到我的網站，該功能表是使用ArcGIS Javascript API編寫的。 我已經設法從Geoserver鏈接了我的圖層並在地圖上查看了此信息，但是我正努力將自己的記錄顯示在網站的表格中。

到目前為止，這是我的代碼：

require([
  "esri/layers/FeatureLayer",
  "esri/dijit/FeatureTable",
  "esri/layers/WMSLayer", 
  "esri/layers/WMSLayerInfo",
  "esri/geometry/Extent",
  "esri/graphicsUtils",
  "esri/tasks/query",
  "esri/symbols/PictureMarkerSymbol",
  "esri/map",
  "dojo/dom",
  "dojo/parser",
  "dojo/ready",
  "dojo/on",
  "dijit/layout/ContentPane",
  "dijit/layout/BorderContainer"
], function (
  FeatureLayer, FeatureTable, WMSLayer, WMSLayerInfo, Extent, graphicsUtils, Query, PictureMarkerSymbol, Map,
  dom, parser, ready, on, ContentPane, BorderContainer
) {

  parser.parse();

  ready(function(){
    var map = new Map("map",{
      basemap: "streets", 
      extent: new Extent({xmax: -1.1487, xmin: 51.065,
        ymax: -1.1274, ymin: 51.097,
        "spatialReference":{"wkid":27700,"latestWkid":4326}
      })
    });

    //Load a FeatureTable to the application once map loads
    map.on("load", loadTable);

    function loadTable(){

      // editable FeatureLayer
      var wmsLayer = new WMSLayer("", {
        mode: WMSLayer.MODE_ONDEMAND,
        outFields: ["*"],
        visible: true,
       id: "fLayer2"
     });

      var wmsLayer = new WMSLayer("http://localhost:8080/geoserver/RSAC/ows?service=wfs&version=1.0.0&request=GetCapabilities", {
  format: "png",
  resourceInfo: {

    getFeatureInfoURL: "http://localhost:8080/geoserver/RSAC/ows",
    getMapURL: "http://localhost:8080/geoserver/RSAC/ows",
    hasAttributionData: true,
    layerInfos: [
      new WMSLayerInfo({
        name: "RSAC:Field_boundary_WGS84_updated",
        title: "Field_boundary_WGS84",
        queryable: true,
        showPopup: true
      })
    ],
    spatialReferences:[3857],
    version: "1.3.0"
  },
  version: "1.3.0",
  visibleLayers: [
    "RSAC:Field_boundary_WGS84_updated"
  ]
});

          wmsLayer.on("error", function (response){
  console.log("Error: %s", response.error.message);
});
    map.addLayer(wmsLayer);

      // set a selection symbol for the featurelayer
      var selectionSymbol = new PictureMarkerSymbol("https://sampleserver6.arcgisonline.com/arcgis/rest/services/RedlandsEmergencyVehicles/FeatureServer/1/images/3540cfc7a09a7bd66f9b7b2114d24eee", 48 ,48);

      wmsLayer.setSelectionSymbol(selectionSymbol);

      // listen to featurelayer click event to handle selection 
      // from layer to the table. 
      // when user clicks on a feature on the map, the corresponding 
      // record will be selected in the table.   
      wmsLayer.on("click", function(evt) {
        var idProperty = wmsLayer.id,
          feature,
          featureId,
          query;

        if (evt.graphic && evt.graphic.attributes && evt.graphic.attributes[idProperty]) {
          feature = evt.graphic,
          featureId = feature.attributes[idProperty];

          query = new Query();
          query.returnGeometry = false;
          query.id = [featureId];
          query.where = "1=1";

          wmsLayer.selectFeatures(query, wmsLayer.SELECTION_NEW);
        }
      });


      // Redlands police vehicle locations layer
      // this layer is an editable layer 
      map.addLayer(wmsLayer);

      //create new FeatureTable and set its properties 
      var wmsLayer = new FeatureTable({
        featureLayer : wmsLayer,
        map : map, 
        editable: true,
        syncSelection: true,
        dateOptions: {
          datePattern: 'M/d/y', 
          timeEnabled: true,
          timePattern: 'H:mm',
        },
        // use fieldInfos object to change field's label (column header), 
        // change the editability of the field, and to format how field values are displayed
        // you will not be able to edit callnumber field in this example. 
        fieldInfos: [
          {
            name: 'id', 
            alias: 'Polygon Id', 
            editable: false //disable editing on this field 
          },
          {
            name: 'photos', 
            alias: 'photos', 
            },
        ],
        // add custom menu functions to the 'Options' drop-down Menu 
         menuFunctions: [
        {
          label: "Field_boundary_WGS84", 
          callback: function(evt){
            console.log(" -- evt: ", evt);
            // set definition expression on the layer
            // show only available emergency vehicles 
            wmsLayer.setDefinitionExpression("status = 0");

            // call FeatureTable.refresh() method to re-fetch features
            // from the layer. Table will only show records that meet 
            // layer's definition expression creteria.  
            wmsLayer.refresh();
          }
        },{

FeatureTable類是僅與要素圖層一起使用的小部件，因此使用wmslayer對象設置為其featurelayer參數設置來創建其實例是錯誤的。

如果必須使用featureTable小部件，則可以執行以下操作。

1. 獲取ArcGIS shapefile或其他受支持的類型。

   • 在geoserver中獲取wmslayer的相應數據。
   • 將數據轉換為arcgis中的shapfile或其他受支持的格式。

2. 使用shapefile與arcgis服務器發布要素服務，因此您可以擁有要素服務。例如： https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/california_census_blocks/FeatureServer/0 : https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/california_census_blocks/FeatureServer/0

3. 用ags api for js編寫代碼

   • 建立地圖
   • 添加要素圖層
   • 添加功能表
