【问题描述】：
我正在尝试将文件上传到 S3 并使用 Amazon SDK 的 ObjectMetadata.setContentDisposition() 对文件名进行 urlencode。文件名可以包含任何 UTF-8 字符和空格。现在文件名在空格上中断，使用特殊字符时出现错误。
我使用的代码sn-p如下：
ObjectMetadata fileMetadata = new ObjectMetadata();
fileMetadata.setContentLength(file.length());
fileMetadata.setContentType(metaContentType);
fileMetadata.addUserMetadata("Filename", metaFileName);
fileMetadata.setContentDisposition("attachment; filename*=UTF-8 " + URLEncoder.encode(metaFileName,"UTF-8"));
不幸的是，这并不像我收到的异常那样正常工作：“AmazonS3Exception：状态代码：403，AWS 服务：Amazon S3，AWS 请求 ID：3F2C3AE3420561BA，AWS 错误代码：SignatureDoesNotMatch，AWS 错误消息：请求签名我们计算的与您提供的签名不匹配。请检查您的密钥和签名方法。”。
