httpclient如何获取dwr的数据？

如题，最好有个简单的范例，谢谢~~

你把dwr官方包里的dwr.war跑在tomcat下

然后运行以下代码

[code="java"]
package com.zte.httpclient.test;

import java.io.FileInputStream;
import java.io.IOException;

import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.PostMethod;

public class HttpClientGetDWRData {

/**
 * @param args
 * @throws IOException 
 * @throws HttpException 
 */
public static void main(String[] args) throws HttpException, IOException {
    // TODO Auto-generated method stub
    HttpClient client = new HttpClient();
    PostMethod  method = new PostMethod("http://localhost:8080/dwr/dwr/call/plaincall/Demo.sayHello.dwr");
    method.setRequestBody(new FileInputStream("postdata.txt"));
    int statusCode = client.executeMethod(method);      

    System.out.println("得到的dwr响应信息如下：");
    System.out.println(method.getResponseBodyAsString());



}

}

[/code]

postdata.txt文件内容如下：
[code="java"]
callCount=1
page=/dwr/simpletext/index.html
httpSessionId=
scriptSessionId=
c0-scriptName=Demo
c0-methodName=sayHello
c0-id=0
c0-param0=string:测试httpclient如何获取dwr的数据
batchId=0

[/code]

得到的打印信息就是

得到的dwr响应信息如下：
throw 'allowScriptTagRemoting is false.';
//#DWR-INSERT
//#DWR-REPLY
dwr.engine._remoteHandleCallback('0','0',"Hello, \u6D4B\u8BD5httpclient\u5982\u4F55\u83B7\u53D6dwr\u7684\u6570\u636E");

"Hello, \u6D4B\u8BD5httpclient\u5982\u4F55\u83B7\u53D6dwr\u7684\u6570\u636E"这个信息就是dwr返回的数据

下载DWR的源文件，包里就有示例，很详细。
DWR网站还有入门教程。
嗯。
入门还是比较简单的 :wink:
