我试图将文件上传到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有断点，当使用特殊字符时，我得到一个错误。
我使用它的代码片段如下:
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，这并没有像我得到的异常一样工作:"AmazonS3Exception:状态代码:403,AWS服务:AmazonS3, AWS请求ID: 3F2C3AE3420561BA, AWS错误代码:SignatureDoesNotMatch, AWS错误消息:我们计算的请求签名与您提供的签名不匹配。请检查您的密钥和签名方法。

我不知道这是否是原因，但用于filename*的编码是不正确的。
