vue-admin 为什么相同的请求用ajax 方式没问题, 但是使用axios 却一直报跨域问题, 在后台已经配置了允许跨域

图片说明

请求方式图片说明

调用该方法 await store.dispatch('user/getUserInfo')

封装的request.js 。 就是 vue-admin-template 里面的js

import axios from 'axios'
import { MessageBox, Message } from 'element-ui'
import store from '@/store'
import { getToken } from '@/utils/auth'

// create an axios instance
const service = axios.create({
baseURL: process.env.VUE_APP_BASE_API, // url = base url + request url
// withCredentials: true, // send cookies when cross-domain requests
timeout: 5000 // request timeout
})

// request interceptor
service.interceptors.request.use(
config => {
// do something before request is sent

if (store.getters.token) {
  // let each request carry token
  // ['X-Token'] is a custom headers key
  // please modify it according to the actual situation
  config.headers['X-Token'] = getToken()
}
return config

},
error => {
// do something with request error
console.log(error) // for debug
return Promise.reject(error)
}
)

// response interceptor
service.interceptors.response.use(
/**

  • If you want to get http information such as headers or status
  • Please return response => response
    */

    /**

  • Determine the request status by custom code

  • Here is just an example

  • You can also judge the status by HTTP Status Code
    */
    response => {
    const res = response.data
    console.log("haha",res);
    // if the custom code is not 20000, it is judged as an error.
    if (res.code !== 20000) {
    Message({
    message: res.message || 'Error',
    type: 'error',
    duration: 5 * 1000
    })

    // 50008: Illegal token; 50012: Other clients logged in; 50014: Token expired;
    if (res.code === 50008 || res.code === 50012 || res.code === 50014) {
    // to re-login
    MessageBox.confirm('You have been logged out, you can cancel to stay on this page, or log in again', 'Confirm logout', {
    confirmButtonText: 'Re-Login',
    cancelButtonText: 'Cancel',
    type: 'warning'
    }).then(() => {
    store.dispatch('user/resetToken').then(() => {
    location.reload()
    })
    })
    }
    return Promise.reject(new Error(res.message || 'Error'))
    } else {
    return res
    }
    },
    error => {
    console.log('err' + error) // for debug
    Message({
    message: error.message,
    type: 'error',
    duration: 5 * 1000
    })
    return Promise.reject(error)
    }
    )

export default service

    // withCredentials: true,
    是不是你注释了跨站点访问啊
