Call this API to get the upload information for each part of a file after it has been split. ## API call description Follow these steps to call the API: Step 1: Call the [Initialize a multipart upload object](/open/development/initialize-a-multipart-upload-object) API to get the upload identifier `uploadKey`. Step 2: Call this API to get the upload information for each part of the file. Step 3: Upload each part in a loop. Step 4: Use the `uploadKey` obtained in Step 1 to call the [Commit file](/open/development/submittal-file) API to complete the upload. For a complete example, refer to the following: ```java theme={"theme":{"light":"github-light","dark":"github-dark"}} import com.aliyun.dingtalkstorage_1_0.models.*; import com.aliyun.teaopenapi.models.Config; import com.aliyun.teautil.models.RuntimeOptions; import com.util.AccessTokenUtil; import org.junit.Test; import java.io.File; import java.io.FileInputStream; import java.io.InputStream; import java.io.OutputStream; import java.net.HttpURLConnection; import java.net.URL; import java.util.Arrays; import java.util.Map; public class MultipartUpload { public static com.aliyun.dingtalkstorage_1_0.Client createClient() throws Exception { Config config = new Config(); config.protocol = "https"; config.regionId = "central"; return new com.aliyun.dingtalkstorage_1_0.Client(config); } @Test public void test() throws Exception { com.aliyun.dingtalkstorage_1_0.Client client = MultipartUpload.createClient(); String spaceId = "Storage space ID"; String filePath = "/Users/xxxxx/Desktop/music.mp3"; // Size of each part long partSize = 1 * 1024 * 1024L; // 1MB // Initialize the multipart upload API InitMultipartFileUploadHeaders initMultipartFileUploadHeaders = new InitMultipartFileUploadHeaders(); initMultipartFileUploadHeaders.xAcsDingtalkAccessToken = "accessToken"; InitMultipartFileUploadRequest initMultipartFileUploadRequest = new InitMultipartFileUploadRequest(); initMultipartFileUploadRequest.setUnionId(unionId); InitMultipartFileUploadRequest.InitMultipartFileUploadRequestOption initMultipartFileUploadRequestOption = new InitMultipartFileUploadRequest.InitMultipartFileUploadRequestOption(); initMultipartFileUploadRequestOption.setStorageDriver("DINGTALK"); initMultipartFileUploadRequest.setOption(initMultipartFileUploadRequestOption); String uploadKey = client.initMultipartFileUploadWithOptions(spaceId, initMultipartFileUploadRequest, initMultipartFileUploadHeaders, new RuntimeOptions()).getBody().getUploadKey(); File file = new File(filePath); long fileLength = file.length(); int partCount = (int) (fileLength / partSize) + ((fileLength % partSize != 0) ? 1 : 0); for (int i = 0; i < partCount; i++) { long startPos = i * partSize; long curPartSize = (i + 1 == partCount) ?
