1、百度输入arcgis aip for javastript 然后进入“ArcGIS API for JavaScript | ArcGIS for Developers”
2、选择"go to 3.24"
3、选择API Reference->esri->basemaps，然后找到请求服务的url
url: "https://services.arcgisonline.com/ArcGIS/rest/services/Specialty/DeLorme_World_Base_Map/MapServer"
4、然后把刚才的URL地址复制过来，不过我们复制到这里就够了

在浏览器中打开，选择World Imagery, 点击WMTS:
然后把点击WMTS后打开的页面的网址复制到ArcGIS中去
5、ArcGIS中：打开ArcMap,Catalog->GIS Servers->Add WMTS Server，网址粘贴上后点击Get Layers
6、点击OK就添加好了，有个红色的×，不用管，双击就好了
