我一直把头撞在墙上，完全被难住了。我正在尝试使用 FineUploader 将文件直接上传到我的 Amazon S3 存储桶。我基本上已经从fineuploader.com 网页（将文件直接上传到Amazon S3）和服务器端PHP 中复制了代码。
当我尝试上传文件时，我看到到签名端点的帖子似乎工作成功，但是当它尝试上传到 S3 时，我收到 405“方法不允许”错误。

/**
* PHP Server-Side Example for Fine Uploader S3.
* Maintained by Widen Enterprises.
*
* Note: This is the exact server-side code used by the S3 example
* on fineuploader.com.
*
* This example:
* - handles both CORS and non-CORS environments
* - handles delete file requests for both DELETE and POST methods
* - Performs basic inspections on the policy documents and REST headers before signing them
* - Ensures again the file size does not exceed the max (after file is in S3)
* - signs policy documents (simple uploads) and REST requests
* (chunked/multipart uploads)
*
* Requirements:
* - PHP 5.3 or newer
* - Amazon PHP SDK (only if utilizing the AWS SDK for deleting files or otherwise examining them)
*
* If you need to install the AWS SDK, see http://docs.aws.amazon.com/aws-sdk-php-2/guide/latest/installation.html.
