umi插件（dva/model）使用

创建model

import { Effect, Reducer, Subscription } from 'umi';

export interface IndexModelState {
  name: string;
}

export interface IndexModelType {
  namespace: 'index';
  state: IndexModelState;
  effects: {
    query: Effect;
  };
  reducers: {
    save: Reducer<IndexModelState>;
    // 启用 immer 之后
    // save: ImmerReducer;
  };
  subscriptions: { setup: Subscription };
}

const IndexModel: IndexModelType = {
  namespace: 'index',

  state: {//状态
    name: 'index',
  },

  effects: {//使用call调用异步方法 put调用reducers
    *query({ payload }, { call, put }) {
       yield put({type:'save',payload})
    },
  },
  reducers: {//操作state
    save(state, action) {
      return {
        ...state,
        ...action.payload,
      };
    },
    // 启用 immer 之后
    // save(state, action) {
    //   state.name = action.payload;
    // },
  },
  subscriptions: {//订阅
    setup({ dispatch, history }) {
      return history.listen(({ pathname }) => {
        if (pathname === '/testDva') {
          dispatch({
            type: 'query',
            payload:{name:"張三"}
          });
        }
      });
    },
  },
};

export default IndexModel;
