文件名中的Amazon S3和西里爾字母

Question

我將文件上傳到包含西里爾字母（right_file_кириллица.csv）的雲時遇到問題。 我的代碼是：

ObjectMetadata meta = new ObjectMetadata();
meta.setContentEncoding("UTF-8");
PutObjectRequest por = new PutObjectRequest(s3Bucket, f.asPath(), new ByteArrayInputStream(bos.toString("UTF-8").getBytes(Charset.forName("UTF-8"))), meta);
PutObjectResult result = s3Client.putObject(por);

bos-這是ByteArrayOutputStream。 這會導致異常：

com.amazonaws.services.s3.model.AmazonS3Exception: The request signature we calculated does not match the signature you provided. Check your key and signing method. (Service: Amazon S3; Status Code: 403; Error Code: SignatureDoesNotMatch; Request ID: A796905192C41ED5)
at com.amazonaws.http.AmazonHttpClient.handleErrorResponse(AmazonHttpClient.java:937)
at com.amazonaws.http.AmazonHttpClient.executeHelper(AmazonHttpClient.java:506)
at com.amazonaws.http.AmazonHttpClient.execute(AmazonHttpClient.java:273)
at com.amazonaws.services.s3.AmazonS3Client.invoke(AmazonS3Client.java:3660)
at com.amazonaws.services.s3.AmazonS3Client.putObject(AmazonS3Client.java:1432)

我在所有可能的地方都設置了UTF-8編碼。 那么，有人知道如何解決該問題嗎？ 謝謝

此信息需要在ContentType中設置，而不是在Content-Encoding中設置：

ObjectMetadata meta = new ObjectMetadata();
meta.setContentType("text/html; charset=utf-8"); 

Content-Encoding通常用於指示主體是否已壓縮（例如設置值gzip或deflate）
