使用 Java SDK 將 Quicktime 視頻上傳到 S3

Question

我正在嘗試將 Quicktime 視頻上傳到 S3，但它已損壞。 我正在使用 Java SDK。 我認為這與多部分有關？ 我需要做什么來阻止它被破壞。 文件正在發送到 S3 正常，但下載和查看時失敗。

//upload video to S3
    PutObjectRequest request2 = new PutObjectRequest(bucketName, "movie.mov", new File(picturePath + "/" + "movie.mov"));

    ObjectMetadata metadata = new ObjectMetadata();
    metadata.setContentType("video/quicktime");
    request2.setMetadata(metadata);

    request2.setCannedAcl(CannedAccessControlList.PublicRead);
    s3Client.putObject(request2);

Answer 1

根據您的問題，我無法判斷您使用的是 AWS Java SDK 的v1還是v2 。

我發現了一個類似的問題，用戶似乎只能上傳小於 5 MB 的.mov文件。 要上傳大於 5 MB 的文件，您可以嘗試使用 Amazon 的高級分段上傳示例，該示例使用TransferManager類，該類內置於 AWS Java SDK v1 中。

這樣，您的代碼將類似於：

try {
    TransferManager tm = TransferManagerBuilder.standard()
            .withS3Client(s3Client)
            .build();

    // TransferManager processes all transfers asynchronously,
    // so this call returns immediately.
    Upload upload = tm.upload(bucketName, "movie.mov", 
        new File(picturePath + "/" + "movie.mov"));
    System.out.println("Object upload started");

    // Optionally, wait for the upload to finish before continuing.
    upload.waitForCompletion();
    System.out.println("Object upload complete");
} catch (AmazonServiceException e) {
    // The call was transmitted successfully, but Amazon S3 couldn't process 
    // it, so it returned an error response.
    e.printStackTrace();
} catch (SdkClientException e) {
    // Amazon S3 couldn't be contacted for a response, or the client
    // couldn't parse the response from Amazon S3.
    e.printStackTrace();
}
