问题描述

在antdpro中使用dva 的@connect给组件注入props，组件取打印this.props查看注入的值为undefined；

问题出现的环境背景及自己尝试过哪些方法

组件代码
@connect(({ testData, loading }) => ({
testData,
loading: loading.effects['test/fetchTestData'],
}))

class Test extends React.Component {
state = {

data: []

}

componentDidMount() {

const { dispatch } = this.props;
  dispatch({
    type: 'test/fetchTestData'
});

}

render() {

console.log(this.props)//输出为注入的Props值为undefined
...

models代码
import { queryTestData} from '@/services/api';

export default {
namespace: 'test',

state: {

testData:[]

},

effects: {

*fetchTestData({ payload }, { call, put }) {
  const response = yield call(queryTestData, payload);//fetch请求
  console.log(response)//成功获取mock数据
  yield put({
    type: 'getData',
    payload: response,
  });
},

},

reducers: {

getData(state, { payload }) {
  
  console.log(state,payload) //此处已打印出上面请求的市局
  return {
    ...state,
    ...payload,
  };
},

},
};
