1.dispatch發(fā)起action請求

dispatch({
  type: 'rule/fetch',
  payload: values,
});

2.找到對應的方法

*fetch({ payload }, { call, put }) {
      yield put({
        type: 'changeLoading',
        payload: true,
      });
      const response = yield call(queryRule, payload);
      yield put({
        type: 'save',
        payload: response,
      });
      yield put({
        type: 'changeLoading',
        payload: false,
      });
    },

疑惑上面的*fetch函數(shù)不是遇到y(tǒng)ield就停止執(zhí)行嗎？那后面三個yield是什么時候觸發(fā)的？
