el-upload上传过程中加进度条，进度条el-progress配合fake-progress一起使用，效果如下：
安装
npm install fake-progress在用到的文件里面引用
import Fakeprogress from "fake-progress";这个进度条主要是假的进度条，他开始加载后一直不会加载到100%，只有在结束的时候才会到100%
<el-progress type="circle" :percentage="parseInt(fake.progress * 100)"></el-progress>
fake: new Fakeprogress({
timeConstant: 10000,
// autoStart: true,
}),
进度条开始：this.fake.start();
进度条结束：this.fake.end();
