Amazon Workdocs API不支持以块/分块形式上传大文件。建议使用Amazon S3来处理大文件上传。以下是Java代码示例：

import com.amazonaws.AmazonServiceException;
import com.amazonaws.SdkClientException;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.client.builder.AwsClientBuilder;
import com.amazonaws.regions.Regions;

import com.amazonaws.services.s3.model.InitiateMultipartUploadRequest;

import com.amazonaws.services.s3.model.PartETag;
import com.amazonaws.services.s3.model.UploadPartRequest;
import com.amazonaws.services.s3.model.UploadPartResult;
import com.amazonaws.util.StringUtils;

                    .withRegion(clientRegion)
                    .build();

            // Step 1: Initialize.
            InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest(bucketName, keyName);
            InitiateMultipartUploadResult initResponse = s3Client.initiateMultipartUpload(initRequest);
            String uploadId = initResponse.getUploadId();

            final long PART_SIZE = 5 * 1024 * 1024; // Set part size to 5 MB.

            try {

                for (int i = 1; filePosition < fullFile.length(); i++) {

                    // Create request to upload a part.
                    UploadPartRequest uploadRequest = new Upload
