Vue 2.x折腾记 - (13) Nuxt.js写一个常规音频的播放组件,动态注入微信,新浪微博的js-sdk

前言

只是一个常规的播放组件,需要考虑微信,微博这类环境的播放

微信和微博,若没有用其官方的js-sdk初始化,没法播放。

我的文章从来都不推崇copy,仅供参考学习..具体业务具体分析定制才是最合理的

前置基础

  • vue && vuex
  • ES5+
  • Nuxt的基本用法

这篇文章的内容需基于上篇内容的,要用到一些设备信息

效果图

这是当前服务端版本的效果,因为还没上线,LOGO已经马赛克

实现思路

之前老的客户端实现思路

  • 在主入口实现一个单例,绑定到vue.prototype
  • 在音频组件的beforeMount创建script标签,引入对应js,然后用promise拿到成功加入head的状态
  • vuex来维护播放状态
  • 在对应的函数初始化音频的加载,之后就可以正常使用了

服务端的思路也差不多

考虑的东西多些,在之前客户端实现的基础上加以完善

用中间件这些来动态注入js-sdk

代码实现

客户端渲染实现的版本

版本1

全部耦合到组件内,虽然可以正常播放(包括微信和微博) 且不是单例模式,对于多音频页面,有毒

版本2

这个版本考虑了多音频播放,所以在主入口直接单例挂载了一个播放器

其次考虑音频的切换播放,所以必须依赖Vuex来共享状态

main.js-主入口
// 创建全局播放器
const music = new Audio();
Vue.prototype.player = music;

复制代码
  • 状态

状态很简单,就一些基础信息,module的方式,state通过getters暴露


export default {
    state: {
        index: '',
        playState: false,
        curTime: '00:00'
    },
    mutations: {
        CURRENT_PLAY: (state, index) => {
            state.index = index;
        },
        CURRENT_TIME: (state, time) => {
            state.curTime = time;
        },

        SetPlayState(state, status) {
            state.playState = status;
        }
    }
};

单例播放器(plugins目录)

  • plugins/player.js

import Vue from "vue";

export default ({ app, store }) => {
  let player = new Audio();
  player.preload = "auto";
  // 把单例的播放器提交到vuex去管控
  store.commit("voice/SetPlayer", player);
};



复制代码
  • nuxt.config.js

因为audio对象只有客户端才有,所以不能服务端初始化 设置ssr:false就代表在客户端的时候才注入,默认不写ssrtrue

module.exports = {
  plugins: [ { src: "~plugins/player.js", ssr: false }]
};

Vuex(store目录)
