Jeecg request URL signature

1、 Turn on url Signature configuration

public class SignAuthConfiguration implements WebMvcConfigurer {
public static String[] urlList = new String[] {"/sys/dict/getDictItems/*", "/sys/dict/loadDict/*",
            "/sys/dict/loadDictOrderByValue/*", "/sys/dict/loadDictItem/*", "/sys/dict/loadTreeData",
            "/sys/api/queryTableDictItemsByCode", "/sys/api/queryFilterTableDictInfo", "/sys/api/queryTableDictByKeys",
            "/sys/api/translateDictFromTable", "/sys/api/translateDictFromTableByKeys","/das.**"};/

2、 Signature interception

public class SignAuthInterceptor implements HandlerInterceptor {
 public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        log.info("request URI = " + request.getRequestURI());
        HttpServletRequest requestWrapper = new BodyReaderHttpServletRequestWrapper(request);
        // Get all parameters ( Include URL and body Upper )
        SortedMap<String, String> allParams = HttpUtils.getAllParams(requestWrapper);
        // Verify the signature of the parameter 
        String headerSign = request.getHeader(CommonConstant.X_SIGN);
        String timesTamp = request.getHeader(CommonConstant.X_TIMESTAMP);
        if (oConvertUtils.isEmpty(headerSign)) {
            headerSign = request.getParameter(CommonConstant.X_SIGN);
        }
        if (oConvertUtils.isEmpty(timesTamp)) {
            timesTamp = request.getParameter(CommonConstant.X_TIMESTAMP);
        }
        ```
3、 Add signature to the front end 

getUrl(){
let timestamp = signMd5Utils.getDateTimeToString()
let url0 = ${this.url.downloadUrl}
let sign = signMd5Utils.getSign(url0, ‘’);
// Put the signature and timestamp , Add to the request interface URL
let _url = url0 +/${this.id}&token=+Vue.ls.get(ACCESS_TOKEN)+&X-Sign=+sign+&X-TIMESTAMP=+timestamp

  let picType =[".jpg",".tif",".png"]
  const  hasPic = picType.filter(item => item == "."+this.filetype)
  if(hasPic != ""){
    return `${window._CONFIG['domianURL']}`+_url
  }
  let url =  `${window._CONFIG['domianURL']}/generic/web/viewer.html?file=${window._CONFIG['domianURL']}`+_url
  return url


},
```
