我要使用阿里云OSS保存网站会员上传的附件，有个问题没弄明白，想请教下～
如果我要使用阿里云OSS保存附件，是不是必须按照下面这样的流程
- 用户上传文件到服务器
- 服务器接收并处理文件
- 服务器通过CURL向OSS提交文件
- 完成后获取返回的数据，将附件展示出来
那么这里就有个问题想请教下了，如何让用户向服务器提交大于1个G的文件
（php默认执行内存，和最大可接收post的参数假定不允许修改）

阿里云OSS支援分段PUT，建议题主看下API文档。
如果服务器只是中转一下，建议修改文件上传的句柄，采用文件不落地，直接流式接收到内存上传到OSS。
担心上传的时候会断连的话，可以用OSS的Multipart上传机制。
如果服务器要做一些处理，也还是建议先流式传到OSS，然后另外一个服务器去OSS取数据做处理，这样的好处是把不同任务分层，每层容易扩展。
这个问题请参照一下文档：http://bbs.aliyun.com/read/262307.html?spm=5176.bbsl211.0.0.Zgncb1 可以利用前端js ＋后端php的方式来处理
