是否可以使用 POST 直接从 URL 上传到 S3? [英] Is it possible to upload to S3 directly from URL using POST?

问题描述

我知道有一种方法可以使用 POST 直接从 Web 浏览器上传到 S3，而无需将文件发送到您的后端服务器.但是有没有办法从 URL 而不是网络浏览器做到这一点.

I know there is a way to upload to S3 directly from the web browser using POST without the files going to your backend server. But is there a way to do it from URL instead of web browser.

例如，使用 post 将位于 http://example.com/dude.jpg 的文件直接上传到 S3.我的意思是我不想将资产下载到我的服务器然后将其上传到 S3.我只想向 S3 发出 POST 请求，然后它会自动上传.

Example, upload a file that resides at http://example.com/dude.jpg directly to S3 using post. I mean I don't want to download the asset to my server then upload it to S3. I just want to make a POST request to S3 and it uploads it automatically.

推荐答案

我发现这篇文章有一些细节.您可能需要以某种方式修改存储桶的安全设置以允许此类交互.

I found this article with some details. You will probably have to modify your buckets' security settings in some fashion to allow this type of interaction.

客户端也会存在一些安全问题，因为您永远不想公开访问您的密钥

There will be some security issues on the client as well since you never want your keys publicly accessible
