《1》简单封装。
- 在src文件夹下新建api文件夹，新建request.js
const _errno = 1
import axios from 'axios'
export function get(url) {
return function (params) {
return axios.get(url, {
params
}).then((res) => {
const { errno, data } =res.data
if(errno = _errno ){ //对数据进行判断 是否正确
return data
}
}).catch(() => {
})
}
}
- 在api文件夹新建index.js
import { get } from './request.js'
const getNews = get('/api/v1/news')
export {
getNews
}
- 使用
import { getNews } from 'api'
methods:{
getData(){
getNews().then((res) => {
})
}
《2》符合更多场景的封装
对request拦截器、response拦截器、统一的错误处理、统一做了超时处理、baseURL等统一进行了封装
新建api文件夹，新建request.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
// 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
新建index.js
import request from '@/utils/request'
export function fetchList(query) {
return request({
url: '/vue-element-admin/article/list', // 可进行地址的拼接
method: 'get',
params: query，
baseURL: 'xxxx' // 可进行覆盖url
})
}
