目录 1. 前言 2. 关于vue-simple-uploader 3. 基于vue-simple-uploader封装全局上传组件 4. 文件上传流程概览 5. 文件分片 6. MD5的计算过程 7. 秒传及断点续传 7.1 对于前端来说 7.2 前端做分片检验：checkChunkUploadedByResponse 8. 源码及后记 8.1 关于第一个分片丢失问题 2019/8/6更新 1. 前言 之前公司要在管理系统中做一个全局上传插件，即切换各个页面的时候，上传界面还在并且上传不会受到影响，这在vue这种spa框架面前并不是什么难题。然而后端大佬说我们要实现 分片上传 、 秒传 以及 断点续传 的功能，听起来头都大了。 很久之前我写了一篇webuploader的文章，结果使用起来发现问题很多，且官方团队不再维护这个插件了， 经过多天调研及踩雷，最终决定基于 vue-simple-uploader 插件实现该功能，在项目中使用起来无痛且稳定。 如果你只是想实现基本的（非定制化的）上传功能，直接使用 vue-simple-uploader ，多读一下它的文档，不需要更多的二次封装。 如果你只是想实现全局上传插件，也可以参照一下我的实现。 如果你用到了分片上传、秒传及断点续传这些复杂的功能，恭喜你，这篇文章的重点就在于此。 本文源码在此： https://github.com

axios - send form data AND non-form data

由 旧街凉风 提交于 2020-07-15 09:07:33
问题 I'm using axios to send data to my nodejs/express server. If I want to send form data, I do the following (and it works fine): const formData = new FormData(); formData.append('nameOfFile', the_file); axios({ method: 'post', url: '/someRoute', data: formData headers: { 'Content-Type': 'multipart/form-data' } }).then(response => { // Do something with response }).catch(err => { // Do something with err }); Again, the above code works fine. Here is the /someRoute endpoint that it goes to: app
