Question

我无法使用MS Graph Java SDK将文件上传到OneDrive，也找不到任何基于Java的示例。

我在这里找到了一个类似（但尚未回答）的问题：MS Graph Java SDK: how to upload a large file to OneDrive?

但是，与上面提出的问题（基于.NET的示例）相比，我设法将更多的代码拼凑在一起，但是仍然没有成功。

        FileSystemInfo fileSystemInfo = new FileSystemInfo();
        fileSystemInfo.createdDateTime = new GregorianCalendar();
        fileSystemInfo.lastModifiedDateTime = new GregorianCalendar();
        DriveItemUploadableProperties properties = new DriveItemUploadableProperties();
        properties.name = "test.jpeg";
        properties.description = "TEST_DESCRIPTION";
        properties.fileSystemInfo = fileSystemInfo;

        IDriveItemCreateUploadSessionRequest request = this.graphServiceClient
                .me()
                .drive()
                .root()
                .createUploadSession(properties)
                .buildRequest();
        UploadSession session = request.post();

        if(Objects.nonNull(session)) {
            int maxSizeChunk = (320 * 1024) * 4;
            String macOsPath = "[ADD YOUR VALID FILE PATH]";
            File file = new File(macOsPath);
            FileInputStream inputStream = new FileInputStream(file);
            ChunkedUploadProvider<File> uploadProvider = new ChunkedUploadProvider(session, this.graphServiceClient, inputStream, maxSizeChunk, File.class);
            IProgressCallback<File> callback = new IProgressCallback<File>() {
                @Override
                public void progress(long l, long l1) {
                    log.info("making progress: " + l + ", " + l1);
                }

                @Override
                public void success(File file) {
                    log.info("Success! " + file.getName());
                }

                @Override
                public void failure(ClientException e) {
                    log.info("Failure! " + e.getMessage());
                }
            };
            uploadProvider.upload(callback, 0);
        }

尝试发布上传会话请求时发生错误：

UploadSession session = request.post();

返回以下错误，而不是返回上载会话：

{
  "error": {
    "code": "invalidRequest",
    "message": "The request is malformed or incorrect.",
    "innerError": {
      "request-id": "b9d4026b-0d8f-44b4-9e9e-8d78a0ea5ea3",
      "date": "2019-05-30T16:20:11"
    }
  }
}

我不完全理解要求DriveItemUploadableProperties的原因，但是您不应该设置其任何属性。

尝试使用此代替：

UploadSession session = this.graphServiceClient
    .me()
    .drive()
    .root
    .itemWithPath("_hamilton.jpg")
    .createUploadSession(new DriveItemUploadableProperties())
    .buildRequest()
    .post();

我个人发现，最有用的示例是SDK本身中的单元测试。在这种情况下，您可以在OneDriveTests.Java中找到它。
