API下载 https://developers.arcgis.com/downloads/apis-and-sdks?product=javascript&version=4.9
一：首先需要打开本地电脑服务 使用的是IIS，（页面调用需要，引用的css.js需要放到服务器上） 服务器打开步骤： https://jingyan.baidu.com/article/6dad5075031a16a123e36ee5.html
二：将 下载的api 放到C 盘 C/inetpub/wwwroot/下
IIS 项目部署步骤：https://jingyan.baidu.com/article/fedf073770f23335ac8977b1.html
三：下载 API 有多版本，尽量下载新版本 3.14 为正常构建 3.14compact 为紧凑版本，在 install.html中有安装与介绍
所下载api 结构
下载的api需要修改 2 个地方
1.C:\Inetpub\wwwroot\arcgis_js_api\library\3.14\3.14\init.js在文本编辑器中打开并搜索文本'[HOSTNAME_AND_PATH_TO_JSAPI]'，并将其替换为"localhost:8080/arcgis_js_api/library/3.14/3.14/"
2.C:\Inetpub\wwwroot\arcgis_js_api\library\3.14\3.14\dojo\dojo.js在文本编辑器中打开并搜索文本'[HOSTNAME_AND_PATH_TO_JSAPI]'，并将其替换为"localhost:8080/arcgis_js_api/library/3.14/3.14/"
四：html代码

var myTiledMapServiceLayer = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/NGS_Topo_US_2D/MapServer");
myMap.addLayer(myTiledMapServiceLayer);
}
dojo.addOnLoad(init);
