伙计们，今天才刚开始使用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
然后按照以下步骤添加WMS层（我添加了// // TEST-START to END）：
<!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“未定义WMSLayerInfo”。我知道它可能非常基础，但是我无法在线找到答案。先谢谢你。
在您的require语句中，您正在尝试加载"esri/layers/WMSLayerInfo"模块Arcgis Javascript API v4.x中不存在的模块]
只需将其从要加载的模块列表中删除。
require([ "esri/Map", "esri/views/SceneView", "esri/layers/WMSLayer", "esri/geometry/Extent" ], function(Map, SceneView, WMSLayer, Extent) { })不要忘记在代码中删除对WMSLayerInfo的任何引用。
