在java中将代码从MSGraph V5.6迁移到MSGraph V6

Question

我得到了在 graph v5.6 中开发的多种方法 但现在我需要将它们更新到 v6.x 我坚持使用这两种方法

更新我通过查询找到的文件的metdada数据

    protected static synchronized FieldValueSet postTagsToFile(GraphServiceClient graphClient, String driveId, String fileId, Map<String, String> metadata){
        metadata.forEach((s, s2) -> {
            if (!s2.isEmpty())
                System.out.println(s + " : " + s2);
        });
        FieldValueSet fieldValueSet = new FieldValueSet();
        metadata.forEach((key, value) -> fieldValueSet.additionalDataManager().put(key, new JsonPrimitive(value)));
        return graphClient.drives(driveId).items(fileId).listItem().fields().buildRequest().patch(fieldValueSet);
    }

问题是，在图表 v6.x 示例中，我需要列表 Id 来更新它，并且我不知道如何在此方法中访问 listId。

还有一个将文件上传到某个位置

    public static String uploadFileToSharedSP(String fileName,String mimeType, String fileContent, String location) throws IOException {
    
        DriveItem newItem = new DriveItem();
        newItem.name = fileName;
        newItem.file = new com.microsoft.graph.models.File();
        newItem.file.mimeType = mimeType;
    
        DriveRequestBuilder driverReq = graphClient.sites(SHARED_SITE_ID).drive();
        DriveItemRequestBuilder driverRootReq = driverReq.root();
        DriveItemRequestBuilder destination = driverRootReq.itemWithPath(location);
    
        DriveItem createdDriveItem = destination.children().buildRequest().post(newItem);
    
        driverReq.items(createdDriveItem.id)
                .content()
                .buildRequest()
                .put(fileContent.getBytes());
    
        return createdDriveItem.webUrl+"?web=1";
    }

在此我不知道如何将包含内容的新文件发布到新 api 中的位置

我找不到可以遵循的例子。

我一直在网上搜索，但我似乎无法找到一种方法来做到这一点。

Answer 1

我能够像这样更新第一个

    public static synchronized FieldValueSet postTagsToFile(GraphServiceClient graphClient, String driveId, String fileId, Map<String, String> metadata){

        ListItemRequestBuilder listItemReq = graphClient.drives().byDriveId(driveId).items().byDriveItemId(fileId).listItem();
        ListItem listItem = listItemReq.get();

        metadata.forEach((s, s2) -> {
            if (!s2.isEmpty())
                System.out.println(s + " : " + s2);
        });
        FieldValueSet fieldValueSet = new FieldValueSet();
        fieldValueSet.setAdditionalData(Collections.unmodifiableMap(metadata));

        SharepointIds sharepointIds = listItem.getSharepointIds();

        FieldValueSet result = graphClient.sites()
                .bySiteId(sharepointIds.getSiteId())
                .lists().byListId(sharepointIds.getListId())
                .items().byListItemId(listItem.getId())
                .fields().patch(fieldValueSet);

        return result;
}

我的错误是我不知道列表项中有一个新的属性，我可以用它来获取该项目所属的listId，然后我可以发布和更新字段。

我的第二个错误是没有在路径末尾添加 :

public static String uploadFileToSharedSP(String fileName,String mimeType, String fileContent, String location) throws Exception {


    Drive drive = graphClient.sites().bySiteId(SHARED_SITE_ID).drive().get();

    String destination = location+"/"+fileName;

    DriveItemUploadableProperties properties = new DriveItemUploadableProperties();
    properties.getAdditionalData().put("@microsoft.graph.conflictBehavior", "replace");

    CreateUploadSessionPostRequestBody uploadSessionRequest = new CreateUploadSessionPostRequestBody();
    uploadSessionRequest.setItem(properties);

    UploadSession uploadSession = graphClient.drives()
            .byDriveId(drive.getId())
            .items()
            .byDriveItemId("root:/"+destination+":")
            .createUploadSession()
            .post(uploadSessionRequest);

    int maxSliceSize = 1_000_000;
    InputStream uploadStream = new ByteArrayInputStream(fileContent.getBytes());
    long streamSize = fileContent.getBytes().length;


    LargeFileUploadTask<DriveItem> largeFileUploadTask = new LargeFileUploadTask<>(
            graphClient.getRequestAdapter(),
            uploadSession,
            uploadStream,
            streamSize,
            maxSliceSize,
            DriveItem::createFromDiscriminatorValue);

    IProgressCallback callback = (current, max) -> logger.info("Uploaded {} bytes of {} total bytes", current, max);
    UploadResult<DriveItem> uploadResult = largeFileUploadTask.upload(5, callback);
    if (uploadResult.isUploadSuccessful()) {
        String itemId = uploadResult.itemResponse.getId();
        String webUrl = uploadResult.itemResponse.getWebUrl();
        logger.info("Upload successful. itemId: {}, webUrl: {}", itemId, webUrl);
        return webUrl+"?web=1";
    } else {
        logger.error("For Upload failed to {}", destination);
        throw new IOException("To: "+destination+", Upload failed");
    }

}
