403 error uploading file on seafile server 8.0.x

[lukali1986]

Recently, our seafile server was upgraded from 6.0 to 8.0, It is found that the original upload interface cannot be used, 403 error occurred.

I checked the official API interface, It is found that the path parameter is not passed during get upload link.
So I modified the source code

GetUploadLinkRequest.cs

        public string ParentDir { get; set; }

        public override string CommandUri
        {
            get { return $"api2/repos/{LibraryId}/upload-link/?p={ParentDir}"; }
        }

        public GetUploadLinkRequest(string authToken, string libraryId, string parentDir = "/")
            : base(authToken)
        {
            LibraryId = libraryId;
            ParentDir = parentDir;
        }

SeafSession.cs

        var req = new GetUploadLinkRequest(AuthToken, libraryId, targetDirectory);
        var uploadLink = await _webConnection.SendRequestAsync(ServerUri, req);

After this modification, I can upload it.
Please fix this bug. In addition, with the upgrade of seafile, some APIs will be often used, such as share links.

I'm happy to contribute this part of the code, but I don't know how to pull request.
Look forward to your reply

At the same time, after repair, the nuget package can be updated.
