查看了其他朋友也⼜遇到这种情况，发现有解决⽅案，需要调⽤on-progress
handleProgress (event, file, fileList) {
progress = (event)=>{
// event.loaded 已经上传了⽂件⼤⼩
// al 上传⽂件总⼤⼩
let uploadPercent = ((event.loaded / al) * 100).toFixed(1) + '%'
console.log(uploadPercent)
}
}
打印出进度了，但我们需要进度条
handleProgress (event, file, fileList) {
console.log('上传中', event); // 继承了原⽣函数的 event 事件
代理之狐console.log('上传中 file', file); // 上传的⽂件
console.log('上传中 fileList', fileList); // 上传⽂件列表包含file
// uploadList 就是原⽂档中的那个渲染的 uplist 是个数组，所以要把filelist 赋值给他
// this.uploadList = fileList 为什么不⽤这个呢，因为我在删除其中⼀个图⽚在添加时，发⽣bug，所以不⽤
this.uploadList.push(file)
// 调⽤监听上传进度的事件
progress = (event) => {
let uploadPercent = parseFloat(((event.loaded / al) * 100).toFixed(2)) // 保留两位⼩数，具体根据⾃⼰需求做更改
// ⼿动设置显⽰上传进度条以及上传百分⽐
file.showProgress = true
file.percentage = uploadPercent
}
}
