import { CONFIG } from '@/consts/config';
import { request } from 'umi';

export async function register() {
  return request(`${CONFIG.URL}/HTRegister`, {
    method: 'POST',
  });
}

export async function register_select() {
  return request(`${CONFIG.URL}/HTRegister_select`, {

/models/register.js

import { register } from '@/services/ant-design-pro/register';
import { register_select } from '@/services/ant-design-pro/register';

export default {
  namespace: 'register',

  state: {
    data: [],
  },

  effects: {
    *queryInitCards(_, sagaEffects) {
      const { call, put } = sagaEffects;

      const respose = yield call(register);
      console.log('请求的返回值test：' + JSON.stringify(respose.info));
      yield put({ type: 'save', payload: respose.info });
    },

    *queryInitCards_s(_, sagaEffects) {
      const { call, put } = sagaEffects;

      const respose = yield call(register_select);
      console.log('请求的返回值test：' + JSON.stringify(respose.info));
      yield put({ type: 'save', payload: respose.info });
    },
  },

  reducers: {
    save(state, action) {
      console.log('处理后的test：' + action.payload);
      return {
        ...state, // es6三点运算符合，有点模糊解释不清楚
        data: action.payload, // 上面与服务器交互完的数据赋值给data,这里的data 对应最上面 state 里面的data
      };
    },
  },
};

• 添加了一个 effect queryInitCards
• const respose = yield call(register);获取服务端数据。
• yield put({ type: 'save', payload: respose.info });添加一个卡片数据。这个会触发 reducer 的执行。于是会看到视图上添加了一个新卡片。

@connect(mapStateToProps, mapDispatchToProps)
class ShoppingList extends React.Component {
  render() {
    console.log('展示的数据test' + JSON.stringify(this.props.userList));
    return (
      <>
        <Card>
          <Button type="primary" onClick={this.props.onDidMount}>
            注册
          </Button>
          <Button type="primary" onClick={this.props.onDidMount_select}>
            查询
          </Button>
        </Card>

        <Table columns={columns} dataSource={this.props.userList} />

export default ShoppingList;

• 通过 mapDispatchToProps 给页面注入方法 onDidMount。页面在 mount 完毕后调用该方法。它发送一个 puzzlecards/queryInitCards 的 action
