Vue 对国际化提供了很好的支持，下面我们来说一下如何国际化

 

安装依赖

执行：npm add vue-i18n

添加配置

在src目录下添加i18n文件夹，并创建一个index.js

index.js

import Vue from 'vue'

import VueI18n from 'vue-i18n'

 

Vue.use(VueI18n)

// 注册i18n实例并引入语言文件，文件格式等下解析

const i18n = new VueI18n({

locale: 'zh_cn',

messages: {

'zh_cn': require('@/assets/languages/zh_cn.json'),

'en_us': require('@/assets/languages/en_us.json')

}

})

export default i18n

然后在assets目录下创建languages目录，在目录中新建两个多语言文件en_us.json、zh_cn.json

en_us.json

{

"common": {

"home": "Home",

"login": "Login",

"logout": "Logout",

"doc": "Document",

"blog": "Blog",

"projectRepo": "Project",

"myMsg": "My Message",

"config": "Config",

"backup": "Backup",

"restore": "Restore",

"backupRestore": "Backup Restore",

"versionName": "Version",

"exit": "Exit"

},

"action": {

"operation": "Operation",

"add": "Add",

"edit": "Edit",

"delete": "Delete",

"batchDelete": "Batch Delete",

"search": "Search",

"loading": "loading",

"submit": "Submit",

"comfirm": "Comfirm",

"cancel": "Cancel",

"reset": "Reset"

}

}

zh_cn.json

{

"common": {

"home": "首页",

"login": "登录",

"logout": "退出登录",

"doc": "文档",

"blog": "博客",

"projectRepo": "项目",

"myMsg": "我的消息",

"config": "系统配置",

"backup": "备份",

"restore": "还原",

"backupRestore": "备份还原",

"versionName": "版本名称",

"exit": "退出"

},

"action": {

"operation": "操作",

"add": "新增",

"edit": "编辑",

"delete": "删除",

"batchDelete": "批量删除",

"search": "查询",

"loading": "拼命加载中",

"submit": "提交",

"comfirm": "确定",

"cancel": "取消",

"reset": "重置"

}

}

 

在main.js中引入

main.js

import Vue from 'vue'

import App from './App'

import router from './router'

import api from './http'

import global from '@/utils/global'

import ElementUI from 'element-ui'

import 'element-ui/lib/theme-chalk/index.css'

import 'font-awesome/css/font-awesome.min.css'

import i18n from './i18n'

 

Vue.use(ElementUI) // 引入Element

Vue.use(api) // 引入API模块

 

Vue.prototype.global = global // 挂载全局配置模块

 

new Vue({

el: '#app',

router,

i18n,

render: h => h(App)

})

 

引用

我们在原本使用字符串的地方引入国际化字符串

在home.vue中添加一个国际化字符串和两个按钮做中英文切换。修改后代码如下：

Home.vue

<template>

<div class="page">

<h2>Home Page</h2>

<li class="fa fa-home fa-lg"></li>

<el-button type="primary" @click="testAxios()">测试Axios调用</el-button>

<el-button type="primary" @click="getUser()">获取用户信息</el-button>

<el-button type="primary" @click="getMenu()">获取菜单信息</el-button>

<h3>{{$t('common.doc')}}</h3>

<el-button type="success" @click="changeLanguage('zh_cn')">简体中文</el-button>

<el-button type="success" @click="changeLanguage('en_us')">English</el-button>

</div>

</template>

 

<script>

import axios from 'axios'

import mock from '@/mock/index.js'

export default {

name: 'Home',

methods: {

// 语言切换

changeLanguage(lang) {

lang === '' ? 'zh_cn' : lang

this.$i18n.locale = lang

this.langVisible = false

},

testAxios() {

axios.get('http://localhost:8080').then(res => { alert(res.data) })

},

getUser() {

axios.get('http://localhost:8080/user').then(res => { alert(JSON.stringify(res.data)) })

},

getMenu() {

axios.get('http://localhost:8080/menu').then(res => { alert(JSON.stringify(res.data)) })

}

}

}

</script>

 

测试

 配置完后我们启动项目，在浏览器访问：http://localhost:8080

可以看到我们添加的内容，然后我们点击English，国际化的字符串就会变成英文

然后我们在点击简体中文，可以看到国际化字符变回了中文

通过 this.$i18n.locale=xxx 方式就可以实现全局切换语言，Vue框架会根据locale的值读取对应国际化多语言文件并进行实时更新。

 

好啦，我们已经完成了多语言国际化
