在控件安装情况下，文件以分片形式上传
请求如下：
POST /rest/2.0/pcs/file?method=upload&app_id=250528&type=tmpfile&dir=%2F/&filename=**X** HTTP/1.1
Cookie: BDUSS=**pansec_X**
Accept: text/*
Content-Type: multipart/form-data; boundary=----------KM7ei4Ef1gL6ae0ei4gL6GI3GI3gL6
User-Agent: netdisk;2.0.0.4;PC;PC-Windows;10.0.17763;uploadplugin
Connection: Keep-Alive
Pragma: no-cache
Host: c.pcs.baidu.com
Cache-Control: no-cache
Content-Length: **X**

Content-Disposition: form-data; name="Filename"
------------KM7ei4Ef1gL6ae0ei4gL6GI3GI3gL6
Content-Disposition: form-data; name="Filedata"; filename=""
Content-Type: application/octet-stream
**...binary...**其中**包含起来的地方为个人信息和提交信息，其中：
- filename为32位大写的字母与数字组合 暂不知产生方法，也许是随机的
- BDUSS实际上这里和通常使用的值不一样，这个值通过查看网页源代码可以看到，为XDUSS值
- Content-Length会自动决定
- 通过multipart/form-data提交的二进制数据分片大小为4M
返回如下：
HTTP/1.1 200 OK
Content-Type: text/html;charset=utf8
Connection: keep-alive
x-bs-client-ip: **X**
x-bs-request-id: **X**
x-bs-file-size: 4194304
Content-MD5: **X**
x-bs-meta-crc32: **X**
x-poms-part-key: **X**
x-bs-version: **X**
Vary: Accept-Encoding
Server: POMS/CloudUI 1.0
Content-Length: **X**
{"md5":"**X**","request_id":**X**}其中x-bs-client-ip和x-bs-request-id为base64编码，解码后内容形式如下：*.*.*.* 为你的出口/公网ip*.*.*.*:*:*:201*-0*-* *:*:* 为内网ip+port+request_id+时间
x-bs-file-size为分片大小，一般是4M
Content-MD5和即为分片的md5，和返回的值一致
x-bs-meta-crc32似乎与我在电脑上计算的CRC32值不一致
x-poms-part-key和x-bs-version一致 32位数字字母小写组合
分片上传返回的md5在全部分片上传结束之后，通过下面这个接口组合成完整的文件
POST /api/create?a=commit&norename&clienttype=6&version=2.0.0.4 HTTP/1.1

path=//*&isdir=0&size=13729324&block_list=["","","",""]&method=POST其中path为网盘路径，根目录则是//+文件名 size是文件总大小，block_list包含一个list，依次是md5值。
最后是浏览器请求了这个，似乎是刷新作用
