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。
