import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class RequestServlet extends HttpServlet {


	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		//1.得到客户机的完整的url地址
		String url = request.getRequestURL().toString();
		System.out.println(url);
		//2.得到客户机的uri
		String uri = request.getRequestURI();
		System.out.println(uri);
		//3.请求参数的参数部分
		String params = request.getQueryString();
		System.out.println(params);
		//4.客户机的ip地址
		String ip = request.getRemoteAddr();

		//5.得到客户机的请求方式get post
		String method = request.getMethod();
		System.out.println(method);

		String contextPath = request.getContextPath();
		System.out.println(contextPath);
	}
