Call this API to initialize a multipart file upload. ## API call description To call the API, follow these steps: Step 1: Call this API to initialize the multipart file upload and obtain the upload identifier `uploadKey`. Step 2: Call the [Get multipart file upload information](/open/development/obtains-the-information-about-multipart-uploads-of-an-object) API to obtain the upload information for each part. 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, see 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 = "Space ID"; String filePath = "/Users/xxxxx/Desktop/music.mp3"; // Size of each file 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) ?
