使用 ArcGIS Javascript API 查看场景服务时出错 - 无法使用 'in' 运算符搜索 'code' 错误

Question

我正在使用 ArcGIS Javascript API 4.11。从我的门户查看场景服务并提供其 ID 时，我遇到了这些错误。

这是我收到的错误的屏幕截图。 Screenshot 01

这是我使用的代码。

require([
  "esri/Map",
  "esri/views/SceneView",
  "esri/layers/SceneLayer",
  "esri/identity/OAuthInfo",
  "esri/identity/IdentityManager",
  "esri/layers/ImageryLayer",
  "esri/views/layers/ImageryLayerView"
], function(
  Map, SceneView, SceneLayer, OAuthInfo, esriId, ImageryLayer, ImageryLayerView
) {
  debugger;
  var info = new OAuthInfo({
    appId: "AnFbtGbH4t9A2XTi",
    // appId: "q244Lb8gDRgWQ8hM",
    // Uncomment the next line and update if using your own portal
    // portalUrl: "https://<host>:<port>/arcgis"
    // Uncomment the next line to prevent the user's signed in state from being shared with other apps on the same domain with the same authNamespace value.
    // authNamespace: "portal_oauth_inline",
    popup: false
  });

  esriId.registerOAuthInfos([info]);

  esriId
  .checkSignInStatus(info.portalUrl + "/sharing")
  .then(function() {
    //displayItems();
  }).catch(function() {
    // Anonymous view
    esriId.getCredential(info.portalUrl + "/sharing");
  });

  var map = new Map({
    basemap: "dark-gray",
    ground: "world-elevation"
  });

  var view = new SceneView({
    container: "viewDiv",
    map: map,
  });

  var sceneLayer = new SceneLayer({
    portalItem: {
      id: "e7bf9f676ed64937bff9f44c84fdae2b"
    },
    popupEnabled: false
  });

  map.add(sceneLayer);
});

正在加载地图，但未加载场景图层。请帮忙。

我在 codepen 中尝试过的具有相同 ID 的类似代码也给了我同样的错误 - https://codepen.io/anon/pen/rEqgJB

Answer 1

portal item you are trying to load is in fact a BuildingSceneLayer. The above code tries to load it as a regular SceneLayer.

这就是 API 报告错误的原因 SceneLayer does not support this layer type（您的屏幕截图中的第二个错误）。

只需将 SceneLayer 替换为 BuildingSceneLayer 即可一切正常：

require([
  "esri/Map",
  "esri/views/SceneView",
  "esri/layers/BuildingSceneLayer"
], function(Map, SceneView, BuildingSceneLayer) {

...

  // Create BuildingSceneLayer and add to the map
  var sceneLayer = new BuildingSceneLayer({
    portalItem: {
      id: "e7bf9f676ed64937bff9f44c84fdae2b"
    },
    popupEnabled: false
  });
  map.add(sceneLayer);

...

});

这是一个固定的Codepen，显示加载图层后的建筑物。 https://codepen.io/arnofiva/pen/c410babb5384945a12b1d8206ebe27ce?editors=1010

实现相同目的的另一种方法是询问 API 到 load an arbitrary layer from a portal item，在这种情况下它会自动检测图层类型：

Layer.fromPortalItem({
  portalItem: {
    id: "e7bf9f676ed64937bff9f44c84fdae2b"
  }
}).then(function(layer) {
  // Adds layer to the map
  map.add(layer);
});
