防止ajax请求参数被修改,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 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();

}
