Request获取url信息以及url带的参数

来源：互联网发布：汽车行业的会计知乎编辑：程序博客网时间：2024/05/16 06:54

通过url访问服务器可以得出连接本服务器所有机器的ip以及端口等信息

在浏览器上输入：

http://192.168.191.1:8080/HttpServletRequestTest/servlet/HttpServletRequestTest?a=1&b=2

可以获得访问服务器所有设备的ip以及端口

以下是输出的日志:

java代码如下：

System.out.println("getRequestURL: "+request.getRequestURL());         System.out.println("getRequestURI: "+request.getRequestURI());         System.out.println("getQueryString: "+request.getQueryString());         System.out.println("getRemoteAddr: "+request.getRemoteAddr());         System.out.println("getRemoteHost: "+request.getRemoteHost());         System.out.println("getRemotePort: "+request.getRemotePort());         System.out.println("getRemoteUser: "+request.getRemoteUser());         System.out.println("getLocalAddr: "+request.getLocalAddr());         System.out.println("getLocalName: "+request.getLocalName());         System.out.println("getLocalPort: "+request.getLocalPort());         System.out.println("getMethod: "+request.getMethod());         System.out.println("-------request.getParamterMap()-------");         //得到请求的参数Map，注意map的value是String数组类型         Map map = request.getParameterMap();         Set<String> keySet = map.keySet();         for (String key : keySet) {String[] values = (String[]) map.get(key);for (String value : values) {System.out.println(key+"="+value);} }         System.out.println("--------request.getHeader()--------");         //得到请求头的name集合         Enumeration<String> em = request.getHeaderNames();         while (em.hasMoreElements()) {String name = (String) em.nextElement();String value = request.getHeader(name);System.out.println(name+"="+value);}
