httpclient模拟HTTP POST

最近要测试并发下公司网站的注册情况，需要模拟POST动作

下面记录下代码

public class TestReg {
	
	public boolean doReg() throws IOException{
		HttpPost httpost = new HttpPost("http://xxxx.xxxx.com/register/succeed/");
		HttpClient httpclient = new DefaultHttpClient();

		List<NameValuePair> nvps=new ArrayList<NameValuePair>();
//需要通过POST提交的参数
		nvps.add(new BasicNameValuePair("realname", "陈一一"));
		nvps.add(new BasicNameValuePair("pass1", "123456"));
		nvps.add(new BasicNameValuePair("pass2", "123465"));
		nvps.add(new BasicNameValuePair("parentemail", "[e-mail]"));
		nvps.add(new BasicNameValuePair("icoType", "1"));
		httpost.setEntity(new UrlEncodedFormEntity(nvps,"utf-8"));
//增加COOKIE
		httpost.setHeader("Cookie", "TOKEN=1234567890");       
		HttpResponse response = httpclient.execute(httpost);
		HttpEntity entity = response.getEntity();   
		BufferedReader br=new BufferedReader(new InputStreamReader(entity.getContent()));
		String temp="";
		int i=0;
		boolean bo=false;
		while((temp=br.readLine())!=null){
			//System.out.println(i);
			//System.out.println(temp);
			
			if(temp.indexOf("我的盒号")>0){
				System.out.println(temp);
				bo=true;
			}
		}
		br.close();
		
		
		return bo;
	}

	public static void main(String[] args) {
		//总注册数
		int sumRuntimes=20;
		//最大线程数
		int maxThread=5;
		threadPoint=maxThread;
		TestReg tr=new TestReg();
		int nowRuntiems=0;
		int maxRuntiems=sumRuntimes/maxThread;
		boolean runPoint=true;
		while(runPoint){
			while(threadPoint==maxThread  ){
				threadPoint=0;
				tr.doTest(maxThread);
				nowRuntiems++;
				System.out.println("开始"+nowRuntiems);
			}
			if(nowRuntiems==maxRuntiems){
				runPoint=false;
			}
		}

	}
	static int threadPoint=0;
	public void doTest(int maxThread){
		int point=0;
		while(point++<maxThread){
			 new Thread(new Runnable(){
	
				public void run() {
					try {
						Date sd=new Date();
						if(doReg()){
							System.out.println("注册成功!");
						}else{
							System.out.println("注册失败");
						}
						Date ed=new Date();
						System.out.println("运行时间="+(ed.getTime()-sd.getTime()));
					} catch (IOException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}finally{
						//完成执行线程
						threadPoint++;
						//System.out.println(threadPoint);
					}
				}
			 }).start();
		}
		
	}
}
