额,也许在handler里生成这个函数后直接调用?

function generator(info) {
return function(args, callbak) {
}
}

handle: function(info, next) {
generator(info)(args, next);
}

是否能在handler里面使用异步事件, 异步事件里面需要调动handler callback里面的info. 不知道应该如何实现

function generate_req(one_row) { //factory函数

  return function(info) {

      urllib.request(one_row.content, { data: info.param }, function (err, data) {
          if (err) {
              console.log('callback error. ' + err.toString());
          }

          data = data.toString();
          try {
              data = JSON.parse(data);
          } catch(e) {
              console.log('callback JSON parse error. ' + e.toString());
          }

          //return data to function(info) here
          return data;

      });

  };

}
