Request获取url信息以及url带的参数

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);
