1.点击文件按钮图标判断上传文件类型图片、视频、文件
// 发送文件入口
async sendFile() {
const imageType = ['jpg', 'png', 'jpeg']
const videoType = ['mkv', 'avi', 'mp4']
const options = {
filters: [
{ name: 'Images', extensions: imageType },
{ name: 'Videos', extensions: videoType },
{ name: 'Files', extensions: ['zip', 'rar'] }
]
}
const result = await dialog.showOpenDialog(options)
if (!result.canceled && result.filePaths) {
const filePaths = result.filePaths[0]
const isImage = imageType.some((e) => filePaths.endsWith(e))
const isVideo = videoType.some((e) => filePaths.endsWith(e))
if (isImage) {
this.sendImage(result)
} else {
this.sendVideo(result, isVideo)
}
}
}2.通过COS 上传demo
async sendFile(result, isVideo) {
const filePaths = result.filePaths[0]
const pathArr = filePaths.split(/\\/)
const fileName = pathArr[pathArr.length - 1]
const path = filePaths.replace(/\\/g, '/')
const file = await this.srcToFile(path, fileName)
const fileContentType = /\.zip$/.test(fileName)
? 'application/x-zip-compressed'
: 'application/x-rar-compressed'
let keyPath = `${common.isUat() ? 'pathUat' : 'pathProd'}`
let data_taskId = ''
this.cos.uploadFile(
{
Bucket,
Region,
Key: keyPath + fileName,
ContentType: isVideo ? 'video/mp4' : fileContentType,
Body: file,
SliceSize: 1024 * 1024 * 5,
onTaskReady: (taskId) => {
data_taskId = `[data-taskId=${taskId}]`
if (isVideo) {
const fs = require('fs')
const videoData = fs.readFileSync(path)
const url = `data:video/mp4;base64,${videoData.toString('base64')}` // 获取本地视频的地址在页面显示
let audioElement = new Audio(URL.createObjectURL(file))
audioElement.addEventListener('loadedmetadata', (_event) => {
let duration = common.formatDuraton(Math.floor(audioElement.duration)) // 获取视频时长
console.log(duration);
})
}
},
onProgress: (info) => {
console.log('onProgress', JSON.stringify(info))
var percent = Math.floor(info.percent * 10000) / 100
var speed = Math.floor((info.speed / 1024 / 1024) * 100) / 100
console.log('进度' + percent + '%; 速度' + speed + 'Mb/s;')
}
},
(err, data) => {
if (err) {
console.log('上传出错', err)
} else {
console.log('上传成功', data)
}
}
)
}3.根据本地路径创建文件对象
// 根据本地路径创建文件对象
srcToFile(src, fileName, mimeType) {
return fetch(src)
.then(function (res) {
return res.arrayBuffer()
})
.then(function (buf) {
return new File([buf], fileName)
})
}
