java - 是否有低级 Swift 类可以在 AWS S3 中上传文件

Question

这里是 Java 中的相同代码，想知道它们是否有一个 swift 等价物，即允许您将文件分成几个部分:

长部分大小 = 5 * 1024 * 1024;

        try {
            AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
                                    .withRegion(clientRegion)
                                    .withCredentials(new ProfileCredentialsProvider())
                                    .build();

            List<PartETag> partETags = new ArrayList<PartETag>();


            InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest(bucketName, keyName);
            InitiateMultipartUploadResult initResponse = s3Client.initiateMultipartUpload(initRequest);

            long filePosition = 0;
            for (int i = 1; filePosition < contentLength; i++) {
                partSize = Math.min(partSize, (contentLength - filePosition));


                UploadPartRequest uploadRequest = new UploadPartRequest()
                        .withBucketName(bucketName)
                        .withKey(keyName)
                        .withUploadId(initResponse.getUploadId())
                        .withPartNumber(i)
                        .withFileOffset(filePosition)
                        .withFile(file)
                        .withPartSize(partSize);

                UploadPartResult uploadResult = s3Client.uploadPart(uploadRequest);
                partETags.add(uploadResult.getPartETag());

                filePosition += partSize;
            }


            CompleteMultipartUploadRequest compRequest = new CompleteMultipartUploadRequest(bucketName, keyName,
                    initResponse.getUploadId(), partETags);
            s3Client.completeMultipartUpload(compRequest);
        }

您可以在此处使用 AWSiOSSDKv2 中的 AWSS3 客户端:https://github.com/aws/aws-sdk-ios

您正在寻找的请求是这样的:https://github.com/aws/aws-sdk-ios/blob/master/AWSS3/AWSS3Model.h#L6618并可以通过此 API 调用:https://github.com/aws/aws-sdk-ios/blob/master/AWSS3/AWSS3Service.h#L1994
