通过程序遍历http请求的所有参数放到hashmap中,用的时候方便了。
如果参数值有中文,那么需要在程序中添加filter转码,或者在下面程序里,对paramValue转码
- public void doGet(HttpServletRequest request, HttpServletResponse response)
- throws ServletException, IOException {
- 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) {
- System.out.println("参数:" + paramName + "=" + paramValue);
- map.put(paramName, paramValue);
- }
- }
- }
