以勇气面对人生的巨大悲恸,用耐心对待生活的小小哀伤。------雨果
首先安装
|-------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8
| hljs shell # axios cnpm i --save axios # 格式化参数插件 cnpm i -- save qs # 对象合并插件 cnpm i -- save lodash # cookie操作 cnpm i -- save vue-cookie
|
然后我们自己封装一个请求组件
首先创建文件
然后放入我们的代码。。。

| hljs javascript import axios from 'axios' import qs from 'qs' import merge from 'lodash/merge' import {Loading, Message} from 'element-ui' import VueCookie from 'vue-cookie'; // 如果是生产环境 使用.env.production配置文件中的VUE_APP_SERVER_URL作为请求前缀 // 如果是开发环境 使用.env.development配置文件中的VUE_APP_BASE_API作为前缀代理拦截 const BASE_URL = process.env.NODE_ENV === 'production' ? process.env.VUE_APP_SERVER_URL : process.env.VUE_APP_BASE_API // 跨域请求,允许保存cookie axios.defaults.withCredentials = true // 创建axios请求 const http = axios.create({ // 设置超时时间 timeout: 1000 * 30, // 跨域情况下带上cookie withCredentials: true, // 设置默认请求头,之后可以随便改 headers: { 'Content-Type': 'application/json; charset=utf-8' }, // 配置是否使用默认api notUseDefaultApi: false }) /** * 请求拦截,所有的请求通过此处 */ let loading http.interceptors.request.use(config => { // elementUI的loading组件 let showLoading = false // 如果传入loading为true,把showLoading置为true if (config.loading === true) { showLoading = true } if (showLoading) { loading = Loading.service({ // 显示在加载图标下方的加载文案 text: config.loadingText || 'ruben正在全力为您加载中...', // 自定义加载图标类名 spinner: 'el-icon-loading', // 遮罩背景色 background: 'rgba(0, 0, 0, 0.7)' }) } // 请求头带上token config.headers.token = VueCookie.get('token') // 判断是否使用全局地址,假设我们要请求其余域名,这里可以配置为true if (!config.notUseDefaultApi) { config.url = BASE_URL + config.url; } // 获取请求方式 const method = config.method // 定义参数变量 const params = {} // 对参数进行格式化,qs官网【https://www.npmjs.com/package/qs】 // 从请求头获取数组格式化类型 // 默认indices【ids[0]=1&ids[1]=2&ids[3]=3】 // 可选 brackets【uds[]=1&ids[]=2&ids[]=3】 // 以及 repeat【ids=1&ids=2&id=3】 const arrayFormat = config.headers.arrayFormat || 'indices' if (method === 'post' && config.headers['Content-Type'] === 'application/x-www-form-urlencoded; charset=utf-8') { // post请求参数处理 config.data = qs.stringify(config.data, { // allowDots为true时 data= 'a.b=c' qs转换出来就是 a:{b:c},可以进行深层次转换 allowDots: true, arrayFormat: arrayFormat }) } else if (method === 'get') { // get请求参数处理 config.params = qs.stringify(config.params, { allowDots: true, arrayFormat: arrayFormat }) config.params = qs.parse(config.params) config.params = merge(params, config.params) } console.log(config) return config }, error => { return Promise.reject(error) }) // elementUI错误弹框设置 let errorMessageAlertOption = { // 消息文字 message: '请求错误', // 主题 success/warning/info/error 【default info】 type: 'error', // 是否显示关闭按钮 showClose: true, // 是否将 message 属性作为 HTML 片段处理 dangerouslyUseHTMLString: true, // 显示时间, 毫秒。设为 0 则不会自动关闭 duration: 3000, // 自定义图标的类名,会覆盖 type customClass: 'el-icon-lightning' } /** * 响应拦截,所有的相应通过此处 */ http.interceptors.response.use(response => { // 如果此时还处于加载中 if (loading) { // 停止加载 loading.close(); } if (response.data && response.data.success === false) { // 如果请求返回错误 // 这里我们把错误通过elementUI的message组件弹框出来,不过我们需要设置一下消息 errorMessageAlertOption.message = response.data.msg // 执行弹框 Message(errorMessageAlertOption); } return response }, error => { // 如果此时还处于加载中 if (loading) { // 停止加载 loading.close(); } console.log(error) // 梅开二度,弹框 // errorMessageAlertOption.message = error.response.data.msg || error.response.data.exception || error.response.data || error.response || error // errorMessageAlertOption.duration = 4000; Message(errorMessageAlertOption) return Promise.reject(error) }) export default http

然后在main.js
引用
|------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
| hljs javascript import Vue from 'vue' import App from './App.vue' import router from '@/router' import ElementUI from 'element-ui'; import 'element-ui/lib/theme-chalk/index.css'; import httpRequest from '@/utils/httpRequest' import VueCookie from 'vue-cookie'; Vue.use(ElementUI, httpRequest, VueCookie); Vue.config.productionTip = false // 挂载全局 Vue.prototype.$http = httpRequest Vue.prototype.$cookie = VueCookie new Vue({ router, render: h => h(App), }).$mount('#app')
|
这里加了两个配置文件,别忘了
|-------------------------|--------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8
| hljs development # 开发环境配置 ENV = 'development' # 代理前缀 VUE_APP_BASE_API = '/ruben' # URL VUE_APP_SERVER_URL = 'http://localhost:8080'
|
以及
|-----------------|------------------------------------------------------------------------------------------|
| 1 2 3 4
| hljs production # 生产环境配置 ENV = 'production' VUE_APP_SERVER_URL = 'localhost:8080'
|
还有在vue的vue.config.js
配置文件中配置
|------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
| hljs javascript module.exports = { devServer: { // 配置端口 port: 3000, // 不检查host disableHostCheck: true, // 配置代理 proxy: { '/ruben': { // 配置URL target: process.env.VUE_APP_SERVER_URL, // 是否允许跨域 changeOrigin: true, // 请求重写,这里是把ruben替换成空串 pathRewrite: { '^/ruben': '' } } } } }
|
最后是使用
|------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10
| hljs vue this.$http({ url: `/user/login`, method: 'post', data: this.inputForm }).then(({data}) => { if (data && data.success) { this.$message.success(data.msg) console.log(data) } });

完整代码放到了gitee
仓库
我会继续完善下去的~
