VUE 跨域POST请求总是失败

Question

1. 问题

Vue调用DjangoRestframework的POST方法总是会被取消发送

2. 代码

api.js

import Vue from 'vue'
import Axios from 'axios';

import VueAxios from 'vue-axios'

import { cookieStorage } from 'src/common/storage'

const myApi = Axios.create({
  baseURL: 'http://localhost:4000/',
  timeout: 5000,
  withCredentials: true,
  transformRequest: [(data) => JSON.stringify(data.data)],
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
  }
})

Vue.use(VueAxios, Axios)

//添加请求拦截器
myApi.interceptors.request.use(config => {
    //在发送请求之前做某事
    let token = cookieStorage.get('user_info').token
    if (token) {
        Axios.defaults.headers.common['Authenticate'] = "Token " + token;
    } else {
        Axios.defaults.headers.common['Authorization'] = "";
        console.log(config)
    }
    return config
}, error => {
    console.log(error)
    return Promise.reject(error)
});

export default myApi

login.vue

...
        api.post('/api-token-auth',data = data).then(
          (resp) => {
            console.log(resp.body)
            this.$store.dispatch(SET_USER_INFO,resp.body)
          }
        ).catch((resp)=>{
          console.log(resp.status)
          console.log(resp.body)
        })
      }
    }

3. 错误截图

在Chrome://net-internals里看到的信息，说明HTTP请求没能发出去
