有一些类似的问题，但都没有在如何使用PHP与进度条直接将文件上传到S3一个很好的答案。它甚至有可能增加一个进度条，不使用Flash技术？

注：我指的是从上传客户端浏览器直接到S3。

NOTE: I am referring to uploading from client browser directly to S3.

推荐答案

我在我们的项目中做到了这一点。使用AJAX，因为标准的跨域的安全策略无法直接上传到S3;相反，你需要使用一个普通的表单POST或Flash。您将需要发送的安全策略和签名在一个相对复杂的过程，如 S3文档解释

I've done this in our project. You can't upload directly to S3 using AJAX because of standard cross domain security policies; instead, you need to use either a regular form POST or Flash. You'll need to send the security policy and signature in a relatively complex process, as explained in the S3 docs.
