一、通过arcmap10.2建模，其中包含三个参数
注意input属性，选择数据类型为要素类：
二、建模之后，加载数据，执行模型，无错误的话，找到执行结果，进行发布gp服务
注意，发布gp服务服务的时候，参数可以设置同步，也可以设置异步，我选择的异步执行
三、发布完gp服务，通过api进行调用

结果如下：
四、分析执行过程：
1.执行提交job 获取到jobid
http://localhost:6080/arcgis/rest/services/kenerDenNew3/GPServer/kenerDen/submitJob
2.取到jobid轮训，直到jobStatus为"esriJobSucceeded"http://localhost:6080/arcgis/rest/services/kenerDenNew3/GPServer/kenerDen/jobs/jc6c8f53ed9ca48419c0705a2bd199014?f=json
