许久没有更新博客，PR值都降了，还是人太懒。

最近做的项目，需要Flash和webservice“互相沟通”，但AS3似乎对webservice的支持不如AS2中那么方便，所以自己写了个简单的类，可以方便的使用Web服务。

package beus.net{
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLLoaderDataFormat;
import flash.net.URLRequestHeader;
import flash.net.URLRequestMethod;
public class ServiceLoader extends URLLoader {
private var _hostName:String;
private var _serviceName:String;
private var _parameters:Array;
public function ServiceLoader(hostName:String,serviceName:String,parameters:Array) {
_hostName=hostName;
_serviceName=serviceName;
_parameters=parameters;
var serviceRequest:URLRequest = generateURLRequest();
this.dataFormat = URLLoaderDataFormat.TEXT;
this.load(serviceRequest);
}
private function generateURLRequest():URLRequest {
var soap:Namespace = new Namespace("http://schemas.xmlsoap.org/soap/envelope/");
var serviceRequest:URLRequest = new URLRequest(_hostName+_serviceName);
serviceRequest.method = URLRequestMethod.POST;
serviceRequest.requestHeaders.push(new URLRequestHeader("Content-Type", "text/xml;charset=utf-8"));
serviceRequest.requestHeaders.push(new URLRequestHeader("SOAPAction", "http://tempuri.org/"+_serviceName));
var rXML:XML =
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body/>
</soap:Envelope>;
var conditionStr:String = "<"+_serviceName+" xmlns=\"http://tempuri.org/\">";

for (var i:Number=0; i<_parameters.length; i++) {
conditionStr+="<"+_parameters[i][0]+">"+_parameters[i][1]+"+_parameters[i][0]+">";
}
conditionStr+="+_serviceName+">";
var conditionXML:XML = new XML(conditionStr);
rXML.soap::Body.appendChild(conditionXML);
serviceRequest.data = rXML;
return serviceRequest;
}
}
}

使用方法：

var parameters:Array = new Array(1);
parameters[0]=["HouseID",id];
var loader:URLLoader = new ServiceLoader(g_serviceHost,"GetSingleHouse",parameters);
loader.addEventListener(IOErrorEvent.IO_ERROR,singleHouseServiceErrorHandler);
loader.addEventListener(Event.COMPLETE,singleHouseLoadedHandler);
loader.addEventListener(ProgressEvent.PROGRESS,singleHouseProgressHandler);
