一样，文件上传大于50M好像就出问题了

你们有这个问题？我这试过上传几个G都正常。

@debug-null 非常感谢您的分享。有个问题还请您修复一下：当文件上传大于50M时，最终只在target文件夹中保留50M。我不太懂后端，希望您能够提供一下修复的代码。非常感谢您

调试成功了，把修改的点总结了一下

1、package.json 中57行改成 "multiparty": "^4.2.2",

2、package.json 中修改第7和8行
"start": "set NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve",
"server": "set NODE_OPTIONS=--openssl-legacy-provider && node server/index.js",

3、App.vue 中52行修改成
zip: [
'application/zip',
'zip',
'application/octet-stream',
'application/x-zip',
'application/x-zip-compressed'
]

4、simple.vue 493行修改成 fileChunkNum: chunkSize,
5、simple.vue 532行修改成 file: file.slice(count, count + size > file.size ? file.size : count + size)

6、controller.js 33行 修改成 chunkPaths.sort((a, b) => parseInt(a, 10) - parseInt(b, 10));
7、controller.js 删除41行 end: (index + 1) * size 修改成 flush: true
8、controller.js 删除66、67行的
const ext = extractExt(fileName);
const filePath = path.resolve(UPLOAD_DIR, ${md5}${ext});
修改成： const filePath = path.resolve(UPLOAD_DIR, fileName);

9、controller.js 删除 89和90行
修改成 const chunkDir = path.resolve(UPLOAD_DIR, hash);
const filePath = path.resolve(chunkDir, filename);
10、nodejs IntelliJ IDEA debug后台调试配置 参照https://www.jetbrains.com/help/idea/running-and-debugging-node-js.html#running
11、postman调试后台接口
