推荐答案

使用 objectProperties.key 选项.

您可以提供一个 String 值或一个将所需键作为 String 返回的函数.

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

下面的示例演示了设置键和执行阻止操作( $.post ).它使用jQuery插件，

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>

一个简单的例子，

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

请记住，如果要防止用户覆盖彼此的文件，则应使这些键为唯一！将每个上传文件放在带有随机密钥的文件夹中可以避免这种情况.

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.
