我正在嘗試使用Amazon S3來存儲我的文件。另外我想用FineUploader上傳圖片到亞馬遜（我使用的是Zend Framework）。在FineUploader上使用Amazon S3時出錯
這是我的看法：
<div id="fineuploader-s3"></div>
這是我的JavaScript文件：（改鍵/桶名稱）
$(document).ready(function() {
$('#fineuploader-s3').fineUploaderS3({
request: {
// REQUIRED: We are using a custom domain
// for our S3 bucket, in this case. You can
// use any valid URL that points to your bucket.
endpoint: "mybucket.s3.amazonaws.com",
// REQUIRED: The AWS public key for the client-side user
// we provisioned.
accessKey: "mykey"
},
// REQUIRED: Path to our local server where requests
// can be signed.
signature: {
endpoint: "/s3/s3demo.php"
},
// OPTIONAL: An endopint for Fine Uploader to POST to
// after the file has been successfully uploaded.
// Server-side, we can declare this upload a failure
// if something is wrong with the file.
uploadSuccess: {
endpoint: "/s3demo.php?success"
},
// USUALLY REQUIRED: Blank file on the same domain
// as this page, for IE9 and older support.
iframeSupport: {
localBlankPagePath: "/server/success.html"
},
// optional feature
retry: {
showButton: true
},
// optional feature
chunking: {
enabled: true
},
// optional feature
resume: {
enabled: true
},
// optional feature
deleteFile: {
enabled: true,
method: "POST",
endpoint: "/s3demo.php"
},
// optional feature
validation: {
itemLimit: 5,
sizeLimit: 15000000
}
});
});
這是在文件夾S3我 's3demo.php' 文件（在公共文件，根文件）：（改鍵/ bucketname）
