从AWS开发Commnity 但是，在许多语言（PHP，JAVA），用于 大文件，你必须使用流 通过这些语言环境 将你的大文件中的一个块 另一个（以填满后 中央记忆与大量的 数据S3所需要的HTTP POST 为上载
From AWS Dev Commnity But in many languages (PHP, Java), for big files, you have to use streams through which the language environment will take chunks of your big file one after the other (in order to fill up central memory with huge amount of data for the http POST of S3 needed for the upload.
有关流的好处是， 他们有一个叫做每当回调 下一个块读出了用于进一步 PUT（在HTTPS的意义上）的数据S3。 您可以使用此回调来计算 并显示在客户端上的进展 用户界面。
The nice thing about stream is that they have a callback called whenever the next chunk is read for to further PUT (in the https sense) data to S3. You can use this callback to compute and display the progress on the client UI.
见的libcurl的文档看到 详细介绍了如何这一切工作。
See the doc of libcurl to see in details how all this works.
更新：它看起来像有两个简单的选择
Update: It looks like there are two straightforward options.
- Flash, via the FileReference class
- With a Java applet
我个人讨厌使用第三方扩展（闪存，Java）来使一个应用程序的功能，但我还没有找到另一种方式。
I personally hate using 3rd party extensions (Flash, Java) to make an app function, but I haven't found another way.
