在 dva 里面怎么做处理异步排队

Question

    * deleteDetails({payload}, {call, put}) {
      const result = yield call(deleteDetails, {payload});
      if (result.code !== 200) {
        throw result.msg;
      } else {
        Toast.success(result.msg, 1);
        yield put(routerRedux.goBack())
      }
    },

先执行定时提示，完成提示则返回上一页，这个怎么处理异步排队

Answer 1

通过call一个Promise来实现:

   * deleteDetails({payload}, {call, put}) {
      const result = yield call(deleteDetails, {payload});
      if (result.code !== 200) {
        throw result.msg;
      } else {
          yield call(() => {
            return new Promise((resolve) => {
              Toast.success(result.msg, 1);
              setTimeout(() => resolve(), 1000)
            });
          });
          yield put(routerRedux.goBack())
      }
    }
