Java如何获取浏览器的请求方法及请求参数呢?

实现思路：
    当GET请求时
	 使用HttpServletRequest对象的getQueryString方法
 	 即可获取相应的参数信息串
    当POST请求时
	 使用getParameterMap获取参数对象信息
	 然后组合为一个请求串

public static String getRequestParams(HttpServletRequest request){
		String requestparams = "";
		if("GET".equalsIgnoreCase(request.getMethod())){
			requestparams = request.getQueryString();
		}else{
			Map<String, String[]> params = request.getParameterMap();
			String queryString = "";
			for (String key : params.keySet()) {
				String[] values = params.get(key);
				for (int i = 0; i < values.length; i++) {
					String value = values[i];
					queryString += key + "=" + value + "&";
				}
			}
			requestparams = queryString;
		}
		requestparams = "请求方法:"+request.getMethod()+" 组合参数串:"+requestparams;
		return requestparams;
	}
