vue3+vite中使用国际化，vue-i18n插件实现_vue3vite 国际化

一、安装

npm install vue-i18n

二、在src文件夹下新建locales文件夹，里面新建三个文件，分别是英文词条文件en.ts，中文词条zh.ts，主文件index.ts，分别如下

en.ts

 zh.ts

 index.ts

import zh from "./zh";
import en from "./en";
 
export default {
  zh,
  en,
};

三、在src同级新建i18n.ts

import { createI18n } from "vue-i18n";
import { getLocale } from "@/utils/init"; // 这个方案是获取当前浏览器的语言环境，代码见下面
import messages from "@/locales";
 
const i18n = createI18n({
  legacy: false,
  locale: getLocale(),
  fallbackLocale: "zh",
  messages,
});
 
export default i18n;

export function getLocale() {
  const language = navigator.language;
  if (language.includes("zh")) {
    return "zh";
  }
  return "en";
}

四、在main.ts中引入使用

import { createApp } from "vue";
import { createPinia } from "pinia";
import vant from "vant";
import "vant/lib/index.css";
import svgIcon from "@/icons/index.vue";
import "@/assets/styles/main.scss";
import { initAPlus } from "@/utils/aplus";
import "@/assets/iconpark.js";
import App from "./App.vue";
import router from "./router";
import i18n from "./i18n";
 
if (import.meta.env.MODE !== "production") {
  import("vconsole").then(({ default: VConsole }) => {
    new VConsole();
  });
}
 
function main() {
  const pinia = createPinia();
  const app = createApp(App);
  app.component("svg-icon", svgIcon);
  app.use(vant).use(router).use(i18n).use(pinia).mount("#app");
 
  initAPlus();
}
 
main();

五、在页面中使用

<script setup lang="ts">
import { useI18n } from "vue-i18n";
const { t, locale } = useI18n();
const zlLengedTxtOne = ref([t("overview.vehicleAudit"), t("overview.target")]); 
</script>
// 在template中使用
<template>
  <div class="lt-title samll-grey-text">
     {{ $t("overview.overallDelivery") }}
  </div>
</template>
