数据准备

let param={
   
   code: "utf-8", 
        datalist: [ 
        {
   
   name:"地方",type:0,heigh:2.5,geom:"POINT(109.588 34.645)"}, 
        {
   
   name:"煽动反",type:2,heigh:3.2,geom:"POINT(109.588 34.645)"} 
        ], 
        filepath: "D:gisdata/gp/aaa/sx_test.shp", 
        geomfiled: "geom", 
        keylist: [ 
        {
   
    
            filedname: "name", 
            type: "string" 
        },{
   
    
            filedname: "type", 
            type: "int" 
        },{
