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
如下所示:
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); } } } }
