指纹识别记录

判断webserver服务器
识别逻辑: 通过构造错误404页面的返回值识别

protected HttpURLRequest requests = new HttpURLRequest();
//通过404判断webSERVER
  try {
      String page404 = requests.url("http://"+this.target.concat("/asdasdsad")).get().body();
      for (WEBServer web : WEBServer.values()) {
          if (!web.getKeywords().isEmpty())
          {
              if (StringUtils.containsAny(page404,web.getKeywords().toArray(new String[]{}))){
                  task.getResult().getSystemInfo().setWebServer(web);
              }
          }
      }
  } catch (MalformedURLException e) {
      e.printStackTrace();
  }
