Question

在此应用程序中，我使用redux作为存储，而我面临的问题是无法访问props对象内部的某些值。

这是获取请求的组件：

class SearchBar extends Component {

state = {
    locationData:''
}


handleExample = ()=>{
this.props.searchData(this.state.locationData);

}

const mapDispatchToProps = (dispatch)=>{

return{
    searchData:(data)=>dispatch(searchData(data))

}
}



export default connect(null, mapDispatchToProps)(SearchBar)

这是动作创建者：

import axios from 'axios'

export const searchData =  (data) =>{
return async (dispatch , getState)=>{
    //async call
    const config = {headers:{'user-    
 key':'7bd05934d767a3a1edhdh0b782cf7bbdc0'}};
    const res = await axios.get(`https://developers.zomato.com/api/v2.1/collections?city_id=2`, config);
    //console.log(res.data.collections);

    dispatch({
        type:'SEARCH_DATA', 
        data,
        payload:res.data
    });

}
};

这是减速器：

const initState={
    SearchData:[]
  }

const dataReducer = (state = initState, action)=>{
switch(action.type){
    case 'SEARCH_DATA':
    return {
        ...state, 
        SearchData:action.payload
      }
    default:
    return state;
}



}

export default dataReducer;

这是生根减少剂

import dataReducer from './dataReducer';
import {combineReducers} from 'redux';

const rootReducer = combineReducers({
data:dataReducer
});


export default rootReducer;

现在我正在尝试将数据分发到该组件的道具中

import React, { Component } from 'react'
import CollectionCard from './CollectionCard'
import {connect} from 'react-redux'
import  { searchData } from '../../store/actions/dataActions'

class Collection extends Component {


  componentDidUpdate(prevProps){


   console.log(this.props.data.searchData)
   //console.log(this.state)


  }

const mapStateToProps = (state)=>({

 data:state.data
 })
 export default connect(mapStateToProps, )(Collection);

现在，当我从道具访问数据时，我可以访问它直到data选项，这样才能正确获取信息

{SearchData: {…}}
SearchData: {collections: Array(36), has_more: 0, share_url: 
"http://www.zoma.to/c-2", display_text: "OR EXPLORE OUR COLLECTIONS", 
has_total: 0}
__proto__: Object

但是我无法访问searchData选项，并且似乎无法理解为什么它不起作用。尝试了讨论中以前的一些解决方案，但还是没有运气。

无法访问来自动作创建者的道具数据
