WMSLayerInfo 未定义 - arcgis 4.13

Question

伙计们，今天刚开始使用 arcgis 并尝试从 geoserver 添加 wms 图层。我正在使用 javascript api v 4.13.

我从这个例子开始：

https://developers.arcgis.com/javascript/latest/sample-code/layers-wms/live/index.html

然后按如下方式继续添加 WMS 层（我添加了 // TEST - START 到 END 部分）：

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" />
    <meta
      name="viewport"
      content="initial-scale=1,maximum-scale=1,user-scalable=no"
    />
    <title>WMSLayer - 4.13</title>

    <style>
      html,
      body,
      #viewDiv {
        padding: 0;
        margin: 0;
        height: 100%;
        width: 100%;
      }
    </style>

    <link
      rel="stylesheet"
      href="https://js.arcgis.com/4.13/esri/themes/light/main.css"
    />
    <script src="https://js.arcgis.com/4.13/"></script>

    <script>
      require([
        "esri/Map",
        "esri/views/SceneView",
        "esri/layers/WMSLayer",
        "esri/layers/WMSLayerInfo",
        "esri/geometry/Extent"
      ], function(Map, SceneView, WMSLayer, WMSLayerInfo, Extent) {
        var layer = new WMSLayer({
          url: "https://ows.terrestris.de/osm/service",
          sublayers: [
            {
              name: "OSM-WMS"
            }
          ]
        });

        var map = new Map({
          basemap: {
            baseLayers: [layer]
          }
        });

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

        // TEST - START
    var layer1 = new WMSLayerInfo({
        name: 'sf:test1',
        title: 'sf:test1'
    });

    var resourceInfo = {
        extent: new Extent(3, 4, 5, 6, {
        wkid: 2236
    }),
        layerInfos: [layer1]
    };

    var wmsLayer = new WMSLayer('https://myserver/geoserver/sf/wms', {
        resourceInfo: resourceInfo,
        visibleLayers: ['sf:test1']
    });

    map.addLayers([wmsLayer]);

    // TEST - END



      });

我收到错误 "WMSLayerInfo is not defined"。我知道它可能是非常基本的东西，但我无法在网上找到答案。先谢谢你。

Answer 1

在您的 require 语句中，您正在尝试加载 "esri/layers/WMSLayerInfo" 模块 ，该模块在 Arcgis Javascript API v4.x[=21 中不存在=]

只需将其从您要加载的模块列表中删除即可。

require([ "esri/Map", "esri/views/SceneView", "esri/layers/WMSLayer", "esri/geometry/Extent" ], function(Map, SceneView, WMSLayer, Extent) { })

不要忘记删除代码中对 WMSLayerInfo 的任何引用，并确保使用 ArcGIS Javascript API v4.x documentation.
