react（82）--方法写在effects里面

effects: {
    *addOrUpdateAssistActivity({ payload, callback }, { call }) {
      try {
        const res = yield call(addOrUpdateAssistActivity, payload);
        if (callback && typeof callback === 'function') {
          yield callback(res);
        }
      } catch (error) {
        console.log(error);
      }
    },
