的特性 '切片',而做了一些反應,服務器端與終極版愛可信:無法讀取得到這個錯誤空

堆棧跟蹤

TypeError: Cannot read property 'slice' of null 
    at dispatchHttpRequest (E:\Projects\real-estate\node_modules\axios\lib\adapters\http.js:84:37) 
    at httpAdapter (E:\Projects\real-estate\node_modules\axios\lib\adapters\http.js:19:10)

    at process._tickCallback (internal/process/next_tick.js:103:7) 

行動

import axios from 'axios'; 

export const FETCH_USER = 'FETCH_USER'; 
export const FETCH_POSTS = 'FETCH_POSTS'; 
const GET_POSTS_URI = '/api/posts'; 

export const fetchPosts =() => { 
     let posts = axios.get(GET_POSTS_URI).catch(err => console.log(err)); 
     return { 
      type: FETCH_POSTS, 
      payload: posts 
     } 
} 

API

渲染
app.get('/api/posts', function(req, res, next) { 
    Post.model.find() 
     .exec() 
     .then(function(posts) { 
      res.send(posts); 
     }, function(err) { 
      return next(err); 
     }); 
}) 

我還有在開發工具的網絡選項卡中的JSON響應,但我無法檢索減速器中的JSON響應。我也沒有得到這個錯誤,當我使用OpenWeatherAPI
