私はこれに対して壁に頭を打つことがあり、完全に困惑しています。私はFineUploaderを使用してAmazon S3バケットに直接ファイルをアップロードしようとしています。私は本質的に、AmazonのS3に直接ファイルをアップロードするfineuploader.comのWebページとサーバサイドのPHPからコードをコピーしました。S3アップスケーラーからS3バケットへの取得方法が許可されていないエラー
ファイルをアップロードしようとすると、署名エンドポイントへの投稿が正常に動作しているように見えますが、S3にアップロードしようとすると405の「メソッドが許可されていません」というエラーが表示されます。

/**
* 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.

これは問題でした。「静的ウェブサイトホスティング」のバケットプロパティは、upload.roughdrag.com.s3.amazonawsに変更した時点で、エンドポイントをupload.roughdrag.com.s3-website-us-east-1.amazonaws.comとして指定します。 comこれは私のために働き始めた。どうもありがとうございました。 – jjj916
私は元のポスターと非常によく似た状況にあります。私のDNS設定を共有できますか？そして、あなたはDNSのためにAmazonを使っていますか？私はバケツのエンドポイント 'BUCKETNAME.s3-website-us-east-1.amazonaws.com'に' uploads.mydomain.com'をマッピングしています。 – Colin
"upload.roughdrag.comを解決した後、このCNAMEを" upload.roughdrag.com.s3-website-us-east-1.amazonaws.com "にマップしたようです。そのCNAMEを" upload.roughdrag "にマッピングしてみてください.com.s3.amazaonaws.com "代わりに" - 私のために働いた – jaspreet21anand
