axios封装，使用拦截器统一处理接口

requests.js

import axios from 'axios'
import {MessageBox, Message} from 'element-ui'

// create an axios instance
const service = axios.create({
    baseURL: process.env.VUE_APP_BASE_API, // url = base url + request url
    // baseURL   此处是取多环境配置的url，也可以直接写死
    // 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()
        // }

        if (config.method === 'post') {
            config.data = JSON.stringify(config.data)
        }
        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

 api.js

import requests from "./requests";


function getPersonInfo(data) {
    return requests({
        url: '/getpersoninfo',
        method: 'post',
        data
    })
}

export {
    getPersonInfo
}

在组件中调用

 import {getPersonInfo} from '../api/api';



 methods: {
            async action() {
                let resp= await getPersonInfo({
                    name: 123
                });
                this.user = resp.data
            }
        }
