S3 Post Policy密钥不支持文件夹

我试图让S3 HTML上传工作,我试图硬编码定义密钥名称,而不是使用${filename}。这是由我的API服务器控制的,但是当我指定带有文件夹分隔符的密钥并将其上传时,它会转换为%2F的html实体。

所以我有这个POST政策:

{
    "expiration": "2017-01-01T00:00:00Z",
    "conditions": [ 
        {"bucket": "mybucket"},
        {"key": "i/1/1.png"},
        {"acl": "public-read"},
        {"Content-Type": "image/png"},
        ["content-length-range", "0", "1048576"]
    ]
}

使用HTML表单:

<html> 
  <head>
    <title>S3 POST Form</title> 
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
  </head>

  <body> 
    <form action="https://mybucket.s3.amazonaws.com/" method="post" enctype="multipart/form-data">
      <input type="hidden" name="key" value="i/1/1.png">
      <input type="hidden" name="AWSAccessKeyId" value="AWS_ACCESS_KEY_ID"> 
      <input type="hidden" name="acl" value="public-read"> 
      <input type="hidden" name="policy" value="base64 policy">
      <input type="hidden" name="signature" value="signature">
      <input type="hidden" name="Content-Type" value="image/png">
      <!-- Include any additional input fields here -->

      File to upload to S3: 
      <input name="file" type="file"> 
      <br> 
      <input type="submit" value="Upload File to S3"> 
    </form> 
  </body>
</html>

上传文件时,文件名最终为:

https://mybucket.s3.amazonaws.com/i%2F1%2F1.png

所以问题是,如何让/成为文字文件夹分隔符?

好吧,我是个白痴。我已经了解到,对于S3,%2F/都是有效的文件夹分隔符。
