怎么用java调接口获取ip和url

1、  通过构建一个Servlet获取请求的信息，先创建一个项目，随后构建Servlet获取请求信息

@WebServlet("/RequestDemo1")

public class RequestDemo1 extends HttpServlet {

private static final long serialVersionUID = 1L;

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

// a.获取和路径相关的数据

System.out.println("完整路径："+request.getRequestURL());

System.out.println("短路径："+request.getRequestURI());

// b.获取相关参数

System.out.println("服务器地址："+request.getRemoteAddr());

System.out.println("地址栏传递参数："+request.getQueryString());

System.out.println("服务器对外端口号："+request.getRemotePort());

System.out.println("客户端请求方式："+request.getMethod());

System.out.println("访问端口号："+request.getServerPort());

System.out.println("请求的资源信息："+request.getServletPath());

}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

doGet(request, response);

}

}

测试结果参考如下所示：
