对接渠道经常会用到，将request转成map集合
以前网上找了个很长，这次渠道自带的方法很舒服，就更新了
代码语言：javascript复制@RequestMapping(value = "/deliver", method = { RequestMethod.POST, RequestMethod.GET })
public void deliver(HttpServletRequest request, HttpServletResponse response) throws IOException {
LOGGER.error("deliver request ip:{},queryString: {},parameter:{}", ServletUtils.getRemoteAddress(request), request.getQueryString(),
request.getParameterMap());
String result = "FAILURE";
try {
Map<String, Object> params = getParameterMap(request);
result = xingfeiService.doDeliver(params);
} catch (Exception e) {
LOGGER.error(e.getMessage(), e);
}
response.getWriter().write(result);
}
/**
* 将请求参数转化为Map
*
* @param request
* @return
*/
public static Map<String, Object> getParameterMap(HttpServletRequest request) {
Map<String, Object> param = new HashMap<>();
try {
Enumeration<String> em = request.getParameterNames();
while (em.hasMoreElements()) {
String key = em.nextElement();
param.put(key, request.getParameter(key));
}
} catch (Exception e) {
e.printStackTrace();
}
return param;
}去除sign生成签名字符串，根据需求修改
代码语言：javascript复制public static String signstr(Map<String, Object> params) throws UnsupportedEncodingException {
if (params == null) {
return null;
}
if (params.get("sign") != null) {
params.remove("sign");
}
List<String> keyList = new ArrayList<>(params.keySet());
Collections.sort(keyList);
StringBuffer sb = new StringBuffer();
for (int i = 0; i < keyList.size(); i ) {
String key = keyList.get(i);
String value = params.get(key).toString();
sb.append(key "=" value "&");
}
String signStr = sb.toString();
return signStr;
}
