protected void	authenticate(HttpRequest request, HttpResponse response) 用户登录或权限验证， 注解为@HttpMapping.auth == true 的方法会执行authenticate方法, 若验证成功则必须调用response.nextEvent();进行下一步操作, 例如: @Override public void authenticate(HttpRequest request, HttpResponse response) throws IOException { UserInfo info = request.currentUser(); if (info == null) { response.finishJson(RET_UNLOGIN); return; } else if (!
void	execute(HttpRequest request, HttpResponse response)
protected void	preExecute(HttpRequest request, HttpResponse response) 预执行方法，在execute方法之前运行，设置当前用户信息，或者加入常规统计和基础检测，例如 : @Override public void preExecute(final HttpRequest request, final HttpResponse response) throws IOException { //设置当前用户信息 final String sessionid = request.getSessionid(false); if (sessionid !

preExecute

protected void preExecute(HttpRequest request,
                          HttpResponse response)
                   throws java.io.IOException

预执行方法，在execute方法之前运行，设置当前用户信息，或者加入常规统计和基础检测，例如 :

      @Override
      public void preExecute(final HttpRequest request, final HttpResponse response) throws IOException {
          //设置当前用户信息
          final String sessionid = request.getSessionid(false);
          if (sessionid != null) request.setCurrentUser(userService.current(sessionid));

          if (finer) response.recycleListener((req, resp) -> {  //记录处理时间比较长的请求
              long e = System.currentTimeMillis() - ((HttpRequest) req).getCreatetime();
              if (e > 200) logger.finer("http-execute-cost-time: " + e + " ms. request = " + req);
          });
          response.nextEvent();
      }
 

参数:

request - HttpRequest

response - HttpResponse

抛出:

java.io.IOException - IOException

authenticate

protected void authenticate(HttpRequest request,
                            HttpResponse response)
                     throws java.io.IOException

用户登录或权限验证， 注解为@HttpMapping.auth == true 的方法会执行authenticate方法, 若验证成功则必须调用response.nextEvent();进行下一步操作, 例如:

      @Override
      public void authenticate(HttpRequest request, HttpResponse response) throws IOException {
          UserInfo info = request.currentUser();
          if (info == null) {
              response.finishJson(RET_UNLOGIN);
              return;
          } else if (!info.checkAuth(request.getModuleid(), request.getActionid())) {
              response.finishJson(RET_AUTHILLEGAL);
              return;
          }
          response.nextEvent();
      }
 

参数:

request - HttpRequest

response - HttpResponse

抛出:

java.io.IOException - IOException

execute

public void execute(HttpRequest request,
                    HttpResponse response)
             throws java.io.IOException

指定者:
