Using Uploadify to POST Directly to Amazon S3
Can anyone tell me how to use Uploadify to upload directly to Amazon S3?
My code is as follows:
$('#fileInput').uploadify({
'fileDataName' : 'file',
'uploader' : 'uploadify.swf',
'script' : 'http://BUCKET-NAME-GOES-HERE.s3.amazonaws.com/',
'cancelImg' : 'cancel.png',
'method' : 'post',
'auto' : true,
'onError': function (a, b, c, d) {
alert('error '+d.type+": "+d.info + ' name: ' + c.name + ' size: ' + c.size);
},
'scriptData' : {
'AWSAccessKeyId': "KEY-GOES-HERE",
'key': "${filename}",
'acl': "public-read",
'policy': "POLICY-STRING-GOES-HERE",
'signature': "SIGNATURE-GOES-HERE",
'success_action_status': '200'
}
});
My (unencoded) policy string looks like this:
{
"expiration": "2100-12-01T12:00:00.000Z",
"condition开发者_如何学Gos": [
{"acl": "public-read"},
{"bucket": "BUCKET-NAME-GOES-HERE"},
{"success_action_status" : 200},
["starts-with", "$filename", ""],
["starts-with", "$folder", ""],
["starts-with", "$key", ""],
["content-length-range", 1, 209715200]
]
}
Using the above code actually allows me to select a file, which it then appears to upload (somewhere), but nothing shows up in my S3 bucket and no errors are returned to the JS console.
Using a regular HTML form to post a file to the S3 bucket works fine.
Any advice?
From this thread the uploadify forum:
<html>
<head>
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript" src="jquery.uploadify.v2.1.0.js"></script>
<link rel="stylesheet" href="uploadify.css" type="text/css" media="screen" />
</head>
<body>
<form>
<input id="fileInput" name="fileInput" type="file" />
</form>
<script type="text/javascript">// <![CDATA[
$(document).ready(function() {
$('#fileInput').uploadify({
'fileDataName' : 'file',
'uploader' : 'uploadify.swf',
'script' : 'http://UPLOADBUCKET/',
'cancelImg' : 'cancel.png',
'auto' : true,
'onError' : function(errorObj, q, f, err) { console.log(err); },
'scriptData' : {
AWSAccessKeyId: "ACCESS_KEY",
key: "foo/${filename}",
acl: "public-read",
policy: "POLICY STRING"
signature: "SIGNATURE,
success_action_status: '200'
}
});
});
// ]]></script>
</body>
</html>
The base for the policy string is as follows:
{ "expiration": "2100-12-01T12:00:00.000Z",
"conditions": [
{"acl": "public-read" },
{"bucket": "UPLOADBUCKET" },
{"success_action_status" : '200'},
["starts-with", "$filename", "" ],
["starts-with", "$folder", "" ],
["starts-with", "$key", "foo"],
["content-length-range", 1, 209715200]
]
}
I managed to get a direct upload to Amazon S3 with progress bar working ive got a working demo here.
If anyone is interested it will support buckets and folders within bucket working on producing a wordpress plugin for this.
This is using swfupload, tho working on uploadify ill post when its done.

this is the java code for saving image into s3cloud. add this code into your uploadscript file (like uploadify.php) you will have your own uploadify script file.
AWSCredentials credentials = new AWSCredentials(_ACCESS_KEY, _SECRET_KEY);
log.info("oovfilepath : " + oovfilepath);
log.info("name : " + name);
S3Service s3Service = new RestS3Service(credentials);
S3Bucket s3Bucket = s3Service.createBucket(_BUCKET_NAME);
AccessControlList bucketAcl = s3Service.getBucketAcl(s3Bucket);
bucketAcl.grantPermission(GroupGrantee.ALL_USERS,
Permission.PERMISSION_READ);
InputStream input = new FileInputStream(oovfilepath);
S3Object s3Object = new S3Object(s3Bucket, name);
log.info("s3Object:" + s3Object);
s3Object.setAcl(bucketAcl);
s3Object.setDataInputStream(input);
log.info("s3Object:" + s3Object);
s3Service.putObject(s3Bucket, s3Object);
加载中,请稍侯......
