换一种videoList的遍历方式<script> import fs from 'fs' import path from 'path' export default { name: 'FullScreenVideoPlayer', data() { return { currentVideoIndex: 0, // 当前播放的视频索引 videoList: [], // 视频列表 autoplayInterval: null // 自动播放的定时器 } }, computed: { currentVideoSrc() { return this.videoList[this.currentVideoIndex].src } }, mounted() { const video = this.$refs.videoPlayer video.addEventListener('ended', () => { this.playNextVideo() }) // 自动播放 video.play() this.autoplayInterval = setInterval(() => { this.playNextVideo() }, 5000) // 读取本地文件夹中的视频文件 const videoFolderPath = path.join(__dirname, './src/video/') fs.readdir(videoFolderPath, (err, files) => { if (err) { console.error(err) } else { this.videoList = files.filter(file => { return path.extname(file).toLowerCase() === '.mp4' }).map(file => { return { src: `./src/video/${file}`, name: file } }) } }) }, beforeUnmount() { // 清除定时器 clearInterval(this.autoplayInterval) }, methods: { playNextVideo() { const video = this.$refs.videoPlayer this.currentVideoIndex++ if (this.currentVideoIndex >= this.videoList.length) { this.currentVideoIndex = 0 } video.src = this.currentVideoSrc video.play() }, toggleFullScreen() { const video = this.$refs.videoPlayer if (document.fullscreenElement) { document.exitFullscreen() } else { video.requestFullscreen() } } } } </script>

这段代码是一个Vue组件，用于全屏播放本地视频文件夹中的MP4视频文件。其中，videoList数组存储了所有的视频文件信息，currentVideoIndex表示当前播放的视频索引，currentVideoSrc是根据当前索引获取的当前视频源地址。在mounted钩子函数中，使用Node.js的fs模块读取本地视频文件夹中所有的MP4视频文件，并将视频信息存储到videoList数组中。在播放下一个视频时，会先将当前视频索引值加一，然后判断是否超出了视频列表的范围，如果超出了，则将索引值重置为0，最后根据当前索引获取当前视频源地址，并调用play()方法开始播放。toggleFullScreen()方法用于全屏切换。

fs的遍历文件夹方式运行的时候打不开，帮我修改一下，不用fs的遍历方式去遍历本地文件夹里的视频<template> <div class="video-container"> <video ref="videoPlayer" @ended="playNextVideo" @click="toggleFullScreen" controls></video> </div> </template> <script> import fs from 'fs'; export default { name: 'FullScreenVideoPlayer', data() { return { currentVideoIndex: 0, // 当前播放的视频索引 videoList: [], // 视频列表 autoplayInterval: null // 自动播放的定时器 } }, computed: { currentVideoSrc() { return this.videoList[this.currentVideoIndex] } }, mounted() { const video = this.$refs.videoPlayer; fs.readdir('./src/video', (err, files) => { if (err) throw err; const videoFiles = files.filter(file => file.endsWith('.mp4')); const videoList = videoFiles.map(file => './src/video' + file); this.videoList = videoList; video.src = this.currentVideoSrc; video.play(); this.autoplayInterval = setInterval(() => { this.playNextVideo() }, 5000); }); video.addEventListener('ended', () => { this.playNextVideo() }); }, beforeUnmounted() { // 清除定时器 clearInterval(this.autoplayInterval) }, methods: { playNextVideo() { const video = this.$refs.videoPlayer; this.currentVideoIndex++; if (this.currentVideoIndex >= this.videoList.length) { this.currentVideoIndex = 0 } video.src = this.currentVideoSrc; video.play() }, toggleFullScreen() { const video = this.$refs.videoPlayer; if (document.fullscreenElement) { document.exitFullscreen() } else { video.requestFullscreen() } } } } </script> <style scoped> .video-container { width: 100%; height: 100%; } video { width: 100%; height: 100%; object-fit: contain; } </style>

可以使用 Node.js 内置的 `fs` 模块的同步方法 `readdirSync` 来遍历本地文件夹，修改后的代码如下：

<template>
  <div class="video-container">
    <video ref="videoPlayer" @ended="playNextVideo" @click="toggleFullScreen" controls></video>
  </div>
</template>

<script>
import fs from 'fs';

export default {
  name: 'FullScreenVideoPlayer',
  data() {
    return {
      currentVideoIndex: 0,  // 当前播放的视频索引
      videoList: [],          // 视频列表
      autoplayInterval: null  // 自动播放的定时器
    }
  },
  computed: {
    currentVideoSrc() {
      return this.videoList[this.currentVideoIndex]
    }
  },
  mounted() {
    const video = this.$refs.videoPlayer;
    const videoFiles = fs.readdirSync('./src/video');
    const videoList = videoFiles.filter(file => file.endsWith('.mp4')).map(file => './src/video/' + file);
    this.videoList = videoList;
    video.src = this.currentVideoSrc;
    video.play();
    this.autoplayInterval = setInterval(() => {
      this.playNextVideo()
    }, 5000);
    video.addEventListener('ended', () => {
      this.playNextVideo()
    });
  },
  beforeUnmounted() {
    // 清除定时器
    clearInterval(this.autoplayInterval)
  },
  methods: {
    playNextVideo() {
      const video = this.$refs.videoPlayer;
      this.currentVideoIndex++;
      if (this.currentVideoIndex >= this.videoList.length) {
        this.currentVideoIndex = 0
      }
      video.src = this.currentVideoSrc;
      video.play()
    },
    toggleFullScreen() {
      const video = this.$refs.videoPlayer;
      if (document.fullscreenElement) {
        document.exitFullscreen()
      } else {
        video.requestFullscreen()
      }
    }
  }
}
</script>

<style scoped>
.video-container {
  width: 100%;
  height: 100%;
}

video {
  width: 100%;
  height: 100%;
  object-fit: contain;
}
</style>

请注意，`readdirSync` 是同步方法，执行过程中会阻塞主线程，因此对于大文件夹或者需要实时响应的场景不太适用。如果要遍历大文件夹或者需要实时响应，可以使用 `readdir` 方法异步遍历，或者使用第三方的文件遍历库。

你换一种对videoList的遍历本地文件夹的方式，这个fs浏览器不支持<template> <div class="video-container"> <video ref="videoPlayer" @ended="playNextVideo" @click="toggleFullScreen" controls></video> </div> </template> <script> import fs from 'fs'; export default { name: 'FullScreenVideoPlayer', data() { return { currentVideoIndex: 0, // 当前播放的视频索引 videoList: [], // 视频列表 autoplayInterval: null // 自动播放的定时器 } }, computed: { currentVideoSrc() { return this.videoList[this.currentVideoIndex] } }, mounted() { const video = this.$refs.videoPlayer; // 读取本地文件夹内的视频文件 fs.readdir('./src/video', (err, files) => { if (err) throw err; // 过滤非视频文件 const videoFiles = files.filter(file => file.endsWith('.mp4')) // 将视频文件的路径存入 videoList 数组中 this.videoList = videoFiles.map(file => './src/video/' + file) // 自动播放 video.src = this.currentVideoSrc; video.play(); this.autoplayInterval = setInterval(() => { this.playNextVideo() }, 5000); }); video.addEventListener('ended', () => { this.playNextVideo() }); }, beforeUnmounted() { // 清除定时器 clearInterval(this.autoplayInterval) }, methods: { playNextVideo() { const video = this.$refs.videoPlayer; this.currentVideoIndex++; if (this.currentVideoIndex >= this.videoList.length) { this.currentVideoIndex = 0 } video.src = this.currentVideoSrc; video.play() }, toggleFullScreen() { const video = this.$refs.videoPlayer; if (document.fullscreenElement) { document.exitFullscreen() } else { video.requestFullscreen() } } } } </script> <style scoped> .video-container { width: 100%; height: 100%; } video { width: 100%; height: 100%; object-fit: contain; } </style>

可以使用 Node.js 的 fs 模块来实现遍历本地文件夹，代码如下：

const fs = require('fs');

fs.readdir('./src/video', (err, files) => {
  if (err) throw err;

  const videoFiles = files.filter(file => file.endsWith('.mp4'));
  const videoList = videoFiles.map(file => './src/video/' + file);

  this.videoList = videoList;
});

这段代码与之前的差别在于，使用了 require 导入了 fs 模块，并且使用了 fs.readdir 方法来读取指定文件夹中的文件，然后过滤出以 .mp4 结尾的视频文件，最后将视频文件的路径存入 videoList 数组中。
