直接上程式碼，僅供參考：

private void showParams(HttpServletRequest request) {

Map map = new HashMap();

Enumeration paramNames = request.getParameterNames();

while (paramNames.hasMoreElements()) {

String paramName = (String) paramNames.nextElement();

String[] paramValues = request.getParameterValues(paramName);

if (paramValues.length == 1) {

String paramValue = paramValues[0];

if (paramValue.length() != 0) {

map.put(paramName, paramValue);

}

}

}

Set<Map.Entry<String, String>> set = map.entrySet();

System.out.println("------------------------------");

for (Map.Entry entry : set) {

System.out.println(entry.getKey() + ":" + entry.getValue());

}

System.out.println("------------------------------");

}
