来自 AWS 开发社区但是在许多语言(PHP、Java)中，对于大文件，你必须使用流通过它的语言环境将占用您大文件的一大块之后(为了填满大量的中央存储器需要 S3 的 http POST 数据用于上传.
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.
流的好处在于他们有一个回调，无论何时下一个块被读取以进一步PUT(在 https 意义上)数据到 S3.您可以使用此回调来计算并在客户端显示进度用户界面.
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.
查看libcurl的文档详细说明所有这些是如何工作的.
See the doc of libcurl to see in details how all this works.
