FineUploader with S3 how to specify object name on S3

问题

Where do I specify the format or pattern for the server name that FineUploader creates when uploading to Amazon S3? I need to have greater control over how the file name and path is created on S3. Thanks.

Use the objectProperties.key option.

You can provide a String value or a function that returns the intended key as a String.

The following example demonstrates setting a key and performing a blocking action ($.post). It uses the jQuery plugin,

// <snip>
objectProperties: {
        key: function(fileId) {
            var keyRetrieval = new qq.Promise(),
                filename = $("#fineUploader").fineUploader("getName", fileId);

            $.post("createKey.html", {name: filename})
                .done(function(data) { keyRetrieval.success(data.key); })
                .fail(function() { keyRetrieval.failure(); });

            return keyRetrieval;
        }
    },
// </snip>

A simpler example,

objectProperties: {
        key: function(fileId) {
            var filename = $("#fineUploader").fineUploader("getName", fileId);
            return fileId + "/" + filename;
        }
    },

Keep in mind that you should make these keys unique if you want to prevent users from overwriting each others' files! Putting each upload in a folder with a random key would prevent this.
