vue项目如何实现国际化?分享一下基于vue-i18n实现国际化的经验

demo源码链接:https://github.com/XieTongXue/how-to/tree/master/vue-internationalization

步骤一:安装vue-i18n

npm install vue-i18n --save

步骤二:main.js文件的配置,在main.js中添加以下跟vue-i18n的使用有关的配置项

// 引入i18n国际化插件
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',
  messages: {
    'zh': require('@/assets/languages/zh.json'),
    'en': require('@/assets/languages/en.json')
  }
})
//将i18n注入到vue实例中
new Vue({
  el: '#app',
  router,
  store,
  i18n,
  components: { App },
  template: '<App/>'
})

两个语言文件(zh.json,en.json)源码如下:

en.json:

{
    "common": {
        "home": "Home",
        "login": "Login",
        "register": "Register",
        "appDownload": "APP Download",
        "aboutUs": "About Us",
        "faq": "FAQ",
        "contact": "Contact Us",
        "join": "Join Us",
        "copyright": "Copyright © ZLGMcu Ltd",
        "news": "News",
        "toggle": "Toggle",
        "welcome": "Welcome, ",
        "userinfo": "Userinfo",
        "firstPage": "Home",
        "setting": "Setting",
        "exit": "Exit"
    },
    "message": {
        "hint1": "Please Input Nickname",
        "hint2": "Please Input Username",
        "hint3": "Please Input Password",
        "hint4": "Don't find picture",
        "hint5": "No Account?",
        "hint6": "Register Now",
        "hint7": "Remember me",
        "hint8": "Can't login in?",
        "placeHolder1": "Nickname",
        "placeHolder2": "Username or Phone Number or Email",
        "placeHolder3": "Password(8 Digits at Least)"
    }
}


zh.json:

{
    "common":{
        "home": "首页",
        "login": "登录",
        "register": "注册",
        "appDownload": "APP下载",
        "aboutUs": "关于我们",
        "faq": "常见问题",
        "contact": "联系方式",
        "join": "加入我们",
        "copyright": "版权说明 © 广州xxx有限公司",
        "news": "消息",
        "toggle": "切换",
        "welcome": "欢迎您,",
        "userinfo": "个人信息",
        "firstPage":  "主页",
        "setting": "设置",
        "exit": "退出"
    },
    "message":{
        "hint1": "请输入昵称",
        "hint2": "请输入账号",
        "hint3": "请输入密码",
        "hint4": "没有找到",
        "hin5": "没有账号?",
        "hint6": "马上注册",
        "hint7": "记住我",
        "hint8": "登录遇到问题?",
        "placeHolder1": "昵称",
        "placeHolder2": "用户名、手机号或邮箱",
        "placeHolder3": "密码(至少8位字符)"
    }
}


步骤三:使用vue-i18n,请只留意划线或框框部分

代码中的common.welcome对应语言文件中对应的项,各个不同的项引用方式一样,因此不全部展示,点击切换语言触发changeLanguage()方法,改变i18n实例中locale的值,进而实现语言的切换。此文章只展示了英文中文两种语言,其实多语言也一样,只要多写几个语言文件,然后在main.js中进行对应的配置就行。

由于main.js中设置了默认显示zh即中文,所以没有点击切换语言按钮前的效果为:

点击切换语言后的效果为:

假如在js中需要国际化,可写成以下形式,举个data中的值国际化的例子:

computed: {
   type () {
     return this.$t('xxx.xxx.xxx')
  }
}

或者: 
 data () {
    return {
        msg: '默认文字'
    }
}

methods: {
    changeLanguage () {
       // 同上,以下多加一行
       this.msg = this.$t('xxx.xxx.xxx')
    }
}

国际化的实现方式有很多,有想到其他方法的欢迎分享;本文的只是其中一种,觉得有不足的地方欢迎指出。
