Vue基于element-ui将视频文件切片上传需要借助一些第三方库,例如`vue-axios`和`axios`,以及`hls.js`用于切片视频。下面是一个简单的示例:
1. 安装依赖:
```bash
npm install vue-axios axios element-ui hls.js --save
```
2. 在Vue组件中引入依赖:
```javascript
import axios from 'axios'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import VueAxios from 'vue-axios'
import Hls from 'hls.js'
Vue.use(ElementUI)
Vue.use(VueAxios, axios)
```
3. 在Vue组件中添加上传方法:
```javascript
methods: {
upload() {
const file = this.$refs.fileInput.files[0]
const chunkSize = 1024 * 1024 // 每个切片的大小,这里设置为1MB
const totalChunks = Math.ceil(file.size / chunkSize) // 计算总共的切片数
const formData = new FormData()
formData.append('name', file.name)
formData.append('type', file.type)
formData.append('totalChunks', totalChunks)
const xhr = new XMLHttpRequest()
xhr.open('POST', '/upload', true)
xhr.setRequestHeader('Content-Type', 'multipart/form-data')
xhr.send(formData)
let currentChunk = 0
let startByte = 0
let endByte = chunkSize
const uploadChunk = () => {
const chunk = file.slice(startByte, endByte)
const reader = new FileReader()
reader.readAsArrayBuffer(chunk)
reader.onload = () => {
const arrayBuffer = reader.result
const hls = new Hls()
hls.on(Hls.Events.MEDIA_ATTACHED, () => {
hls.loadSource(arrayBuffer)
hls.on(Hls.Events.FRAG_LOADED, () => {
startByte = endByte
endByte = startByte + chunkSize
currentChunk++
if (currentChunk < totalChunks) {
uploadChunk()
} else {
this.$message.success('上传完成')
}
})
})
}
}
uploadChunk()
}
}
```
4. 在Vue组件中添加上传文件的表单:
```html
<el-form ref="form" :model="form">
<el-form-item label="上传文件">
<input type="file" ref="fileInput" @change="upload" />
</el-form-item>
</el-form>
```
注意:上面的示例只是一个简单的示例,实际情况中还需要根据自己的需求进行修改和完善。
