我知道有一种方法可以使用​​POST而无需进入后台服务器中的文件浏览器上传到S3直接。但是，有没有办法从URL，而不是网页浏览器做到这一点。

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，使用上传后驻留在 https://m.xsw88.com/allimgs/daicuo/20230911/3491.png.jpg 直接到S3的文件。我的意思是我不想要的资产下载到我的服务器，然后将其上传到S3。我只想做一个POST请求到S3，它会自动上传了。

Example, upload a file that resides at https://m.xsw88.com/allimgs/daicuo/20230911/3491.png.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.
