通過url訪問伺服器可以得出連線本伺服器所有機器的ip以及埠等資訊

在瀏覽器上輸入：

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

可以獲得訪問伺服器所有裝置的ip以及埠

以下是輸出的日誌:

Java程式碼如下：

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()-------");
         //得到請求的引數Map，注意map的value是String陣列型別
         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()--------");
         //得到請求頭的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);
}
