Flex调用WebServer数据与XML基础地图数据进行匹配渲染

1.查找WebServer接口数据

/**
    * 通过调用WebService来获取数据
    * @param date 调用该日期的数据
    */
   private function getDataByWebservice():void
   {
    
    var serviceLabel:String = configXML.webService.estuariesLaterWebService.@serviceLabel;
    var functionName:String = configXML.webService.estuariesLaterWebService.@functionName;
    var webServiceUrl:String = configData.webService[serviceLabel];
    
    var obj:Object=new Object();
    obj.year=ddlYear.selectedItem.toString().substr(0,4);
    obj.month=ddlMonth.selectedItem.toString().substring(0,ddlMonth.selectedItem.toString().indexOf("月"));
    var object:Object=new Object();
    object.filterParams=obj;
    var where:String=JSON.encode(object);
    
    resultLabel.text="0";
    //resultLabel.visible=false;
    MapUni.callWebService(webServiceUrl, functionName, [where], onGetData);
    
   }
   
   /**
    * 监听成功调取数据
    */
   private function onGetData(event:ResultEvent):void
   {
    monitorValueLayer.clear();
    layerxuanran.clear();
    
    var dataStr:String = event.result.toString();
    if(dataStr)
    {
     var dataAry:Array = JSON.decode(dataStr);
     dataGrid.dataProvider =arrangeData(dataAry);
     
//     stationDgc.dataField = configXML.dataField.estuariesDataField.@stationName;
     sectionDgc.dataField = configXML.dataField.estuariesDataField.@sectionName;
    }
    XuanranRiver();//渲染河流
   }

 

 

2.查找XML基础地图数据

 

/**
    * 获取所有河流图层
    **/
   private var heliuArr:Array=new Array();
   
   private function getAllRegionName():void
   {
    var layerName:String=configXML.layers.RiverLayer.@layerName;
    var layerURL:String=MapUni.layerUrl(map,layerName);    
    MapUni.search(layerURL,null,"1=1",onSearchResult);
    //onSearchResult是查询到的地市结果
    function onSearchResult(featureSet:FeatureSet):void
    {
     //将查询到的结果放在数组里    里面是十一个地市
     heliuArr=featureSet.features as Array;
    }
   }

 

 

3.WebServer接口数据与XML基础地图数据进行匹配渲染

/**
    * 渲染匹配河流
    */
   private var simplsy:SimpleLineSymbol;
   private function XuanranRiver():void
   {
    layerxuanran.clear();//清空图层
    
    for each(var heliuGra:Graphic in heliuArr)
    {
     var attribute:Object=heliuGra.attributes;
     var heliuName:String=attribute.NAME;
//     var oo:Object=fader.play();
     for(var i:int=0;i<dataArr.length;i++)
     {
      var graphicnew:Graphic=heliuGra as Graphic;
      var obj:Object=graphicnew.attributes;
      if(heliuName==dataArr[i].RiverName)
      {
       var graphic:Graphic=new Graphic(graphicnew.geometry,null,obj);
       layerxuanran.add(graphic);
       simplsy=new SimpleLineSymbol("solid",0x0000FF,0.9,3);
       
       graphic.symbol = simplsy;
       break;
      }
     }
    } 
    
    
   }
