这段代码中使用了Node.js的fs模块，但是它只能在服务端运行，无法在浏览器中使用。因此，需要在浏览器中使用视频时，需要将视频文件的路径硬编码到videoList数组中，而不是使用fs模块动态读取本地视频文件夹中的视频文件。另外，beforeUnmounted钩子函数应该是beforeUnmounted而不是beforeUnmounted。同时，需要在组件中引入fs模块，这也是不可行的。

我想在vue3环境下在videoList遍历本地文件夹里的视频，帮我修改一下以下代码<template> <div class="video-container"> <video ref="videoPlayer" @ended="playNextVideo" @click="toggleFullScreen" controls></video> </div> </template> <script> export default { name: 'FullScreenVideoPlayer', data() { return { currentVideoIndex: 0, // 当前播放的视频索引 videoList: [ // 视频列表 { src: '/src/video/666.mp4' }, { src: '/src/video/777.mp4' }, ], autoplayInterval: null // 自动播放的定时器 } }, computed: { currentVideoSrc() { return this.videoList[this.currentVideoIndex].src } }, mounted() { const video = this.$refs.videoPlayer video.addEventListener('ended', () => { this.playNextVideo() }) // 自动播放 video.play() this.autoplayInterval = setInterval(() => { this.playNextVideo() }, 5000) }, beforeUnmount() { // 清除定时器 clearInterval(this.autoplayInterval) }, methods: { playNextVideo() { const video = this.$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> <style scoped> .video-container { width: 100%; height: 100%; } video { width: 100%; height: 100%; object-fit: contain; } </style>

你可以使用 Node.js 的 fs 模块来读取本地文件夹内的视频文件，然后将视频文件的路径存入 videoList 数组中。具体实现代码如下：

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

<script>
const fs = require('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('/path/to/folder', (err, files) => {
      if (err) throw err;
      // 过滤非视频文件
      const videoFiles = files.filter(file => file.endsWith('.mp4') || file.endsWith('.avi'))
      // 将视频文件的路径存入 videoList 数组中
      this.videoList = videoFiles.map(file => `/path/to/folder/${file}`)
      // 自动播放
      video.play();
      this.autoplayInterval = setInterval(() => {
        this.playNextVideo()
      }, 5000);
    });

    video.addEventListener('ended', () => {
      this.playNextVideo()
    });
  },
  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>

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

请将 `/path/to/folder` 替换为实际视频文件夹的路径。

vue3下src下面有个video的文件夹，把这个文件夹里mp4格式的视频遍历到videoList里<template> <div class="video-container"> <video ref="videoPlayer" @ended="playNextVideo" @click="toggleFullScreen" controls></video> </div> </template> <script> export default { name: 'FullScreenVideoPlayer', data() { return { currentVideoIndex: 0, // 当前播放的视频索引 videoList: [ // 视频列表 { src: '/src/video/666.mp4' }, { src: '/src/video/777.mp4' }, ], autoplayInterval: null // 自动播放的定时器 } }, computed: { currentVideoSrc() { return this.videoList[this.currentVideoIndex].src } }, mounted() { const video = this.$refs.videoPlayer video.addEventListener('ended', () => { this.playNextVideo() }) // 自动播放 video.play() this.autoplayInterval = setInterval(() => { this.playNextVideo() }, 5000) }, beforeUnmount() { // 清除定时器 clearInterval(this.autoplayInterval) }, methods: { playNextVideo() { const video = this.$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> <style scoped> .video-container { width: 100%; height: 100%; } video { width: 100%; height: 100%; object-fit: contain; } </style>

你可以使用之前代码中获取视频列表的方法，将获取到的视频路径动态添加到 `videoList` 数组中。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>
// 引入 fs 模块
const fs = require('fs');

export default {
  name: 'FullScreenVideoPlayer',
  data() {
    return {
      currentVideoIndex: 0, // 当前播放的视频索引
      videoList: [], // 视频列表，初始化为空数组
      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()
    });

    // 获取视频列表
    const videoDirPath = './src/video';
    const fileNames = fs.readdirSync(videoDirPath);
    const mp4FileNames = fileNames.filter(fileName => fileName.endsWith('.mp4'));
    this.videoList = mp4FileNames.map(mp4FileName => {
      return {
        src: `${videoDirPath}/${mp4FileName}`
      };
    });

    // 自动播放
    video.play();
    this.autoplayInterval = setInterval(() => {
      this.playNextVideo()
    }, 5000);
  },
  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>

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

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

这样就可以将视频列表动态遍历到 `videoList` 数组中，然后在页面中渲染出视频列表。
