UWP:使用OneDrive SDK将大文件上传到OneDrive [英] UWP: Upload large files to OneDrive using OneDrive SDK

问题描述

我可以使用以下代码上传小的"文件(<100 MB):

I can upload "small" files (< 100 MB) using the following code:

await OneDriveClient
      .Drive
      .Special
      .AppRoot
      .Children["filename"]
      .Content
      .Request()
      .PutAsync<Item>(contentStream);

对于大文件(> 100 MB)，我读到您必须创建一个Upload Session. 像这样吗?

For Large files (> 100 MB) I read that you have to create an Upload Session. Something like this?

UploadSession uSession = await OneDriveClient
                               .Drive
                               .Special
                               .AppRoot
                               .Children["filename"]
                               .CreateSession(VarChunkedUploadSessionDescriptor)
                               .Request()
                               .PostAsync();

我不确定此后要采取什么步骤? (甚至这是正确的步骤！).希望能有一些汤匙喂食:)预先感谢！

I am not sure what steps are after this? (Or even this is the right step!). Would appreciate some spoon-feeding :) Thanks in Advance!

推荐答案

sdk在此方面有点令人困惑.注意，ItemWithPath没有驱动器根目录....

The sdk is a bit confusing on this. Note, the ItemWithPath is without the drive root....

//uploadPath = "/documentname.docx";
//filename = "documentname.docx";

var request = service.OneDriveClient.Drive.Root.ItemWithPath(uploadPath).CreateSession(new ChunkedUploadSessionDescriptor() { Name = Uri.EscapeUriString(System.IO.Path.GetFileName(filename)) }).Request();
var session = request.PostAsync().Result;


using (var stream = new System.IO.FileStream(filename, System.IO.FileMode.Open))
        {
            if (stream != null)
            {
                Microsoft.OneDrive.Sdk.Helpers.ChunkedUploadProvider chunk = new Microsoft.OneDrive.Sdk.Helpers.ChunkedUploadProvider(
            session, client, stream);
                var item = chunk.UploadAsync().Result; 
            }
        }
