spingboot、vue防止多次请求、参数篡改、数据完整

1、vue请求传值为：时间戳(timeStamp)、随机数(nonce)、sign(url+params参数排序并进行加密)
2、后台获取请求内容，
a、先验证访问时间戳是否超出请求范围
b、验证随机数(nonce)是否已经使用过
c、后台对获取的参数进行排序并加密，验证获取的标签是否与sign是否同一值
注：传参模式vue传参模式为params

@PostMapping("/add")
public AjaxResult add(ServletRequest req) throws IOException, ParseException {

HttpServletRequest request = (HttpServletRequest)req;
HttpServletRequest requestWrapper = new BodyReaderHttpServletRequestWrapper(request);
SortedMap<String, String> allParams = HttpUtils.getAllParams(requestWrapper);
String timeStamp = StringUtils.getString(allParams, "timeStamp");
String nonce = StringUtils.getString(allParams, "nonce");
Long validateTime = DateUtil.stampToDate(timeStamp);
if (validateTime < StringConstants.BALIDATETIME) {
    Object obj = redisService.getCacheObject(nonce);
    if (StringUtils.isNull(obj)) {
        redisService.setCacheObject(nonce, nonce);
        boolean isSigned = SignUtil.verifySign(allParams);
        if (isSigned) {
            return toAjax(countService.insertAccount(allParams));
        } else {
            return AjaxResult.error();
        }
    } else {
        return AjaxResult.error();
    }
} else {
    return AjaxResult.error();
}
