HttpClient

loggcomm.jar是一个log日志包，没有的话会有异常

HttpClient.execute(HttpUriRequest arg0, ResponseHandler<? extends String> arg1)

protected void service(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		// TODO Auto-generated method stub
		HttpClient hc=new DefaultHttpClient();
		HttpGet hg=new HttpGet("http://localhost:8080/blina/s/fdojfldj");
		HttpResponse hp1=null;
		String hp;
		try {
			ResponseHandler<String> responseHandler = new BasicResponseHandler();//这个是泛型是请求返回的格式
			hp=hc.execute(hg,responseHandler);//hp就是responseHandler的泛型。
						String strResult;
			resp.getWriter().print(hp);
		
		} catch (Exception e) {
			// TODO: handle exception
				e.printStackTrace();
		
	}

HttpClient.execute(HttpUriRequest arg0)

protected void service(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		// TODO Auto-generated method stub
		HttpClient hc=new DefaultHttpClient();

		try {
			hp=hc.execute(hg);

			if (hp.getStatusLine().getStatusCode() == 200) {  
				strResult = EntityUtils.toString(hp.getEntity());  
				System.out.println(strResult+"=====================");
				resp.getWriter().print(strResult);

			// TODO: handle exception
				e.printStackTrace();
		
	}

http://localhost:8080/blina/s/fdojfldj这个请求到服务器端是这样的：

protected void service(HttpServletRequest arg0, HttpServletResponse arg1)
			throws ServletException, IOException {
		// TODO Auto-generated method stub
		System.out.println("--------+++++++++++++++++++++++++++----------");
		PrintWriter pw=arg1.getWriter();
		pw.write("{'ff':'fd',{'dd':'gg'}}");
		
	}

返回{'ff':'fd',{'dd':'gg'}}
