WOPI プロトコルを実装する独自のサーバーを作成できます。これは、表示/編集モードで PPTX/XSLX をサポートし、表示モードでのみ DOCX/PDF をサポートします。WOPI サーバーの実装は非常に簡単です。
Word ドキュメントを編集するには、Cobalt または FSSHTTP/FSSHTTPB プロトコルを実装する必要があります。
Office Web Apps では、すべてのユーザーが有効な Office ライセンスを持っている必要があります。
サンプルの .NET WOPI サーバーを次に示します。
次のように呼び出します。

2014 年 6 月 13 日の更新:
Cobalt API を使用すると、Word 文書を編集できますが、私の実装は完璧にはほど遠いものです。基本から始めましょう。FSSHTTP には Shredded Storage、SharePoint がデータベースに実装されている必要がありますが、Cobalt Assembly を調べた後、ファイル システムに細断ファイルを作成する方法を特定しました。関連するコードの断片を以下に示します。この最初の部分は c から単語 doc を取得します。 :\tmp\test.docx に変換され、c:\tmp\filestore および c:\tmp\wacupdate で細断された BLOB に変換されます
DisposalEscrow disposal = new DisposalEscrow("temp1");
CobaltFilePartitionConfig content = new CobaltFilePartitionConfig();
content.IsNewFile = false;
content.HostBlobStore = new FileSystemHostBlobStore("C:\\tmp\\filestore\\", "filestore", new FileSystemHostBlobStore.Config(), disposal, true, false);
content.cellSchemaIsGenericFda = true;
content.CellStorageConfig = new CellStorageConfig();
content.Schema = CobaltFilePartition.Schema.ShreddedCobalt;
content.PartitionId = FilePartitionId.Content;
CobaltFilePartitionConfig wacupdate = new CobaltFilePartitionConfig();
wacupdate.IsNewFile = false;
wacupdate.HostBlobStore = new FileSystemHostBlobStore("C:\\tmp\\wacstore\\", "wacstore", new FileSystemHostBlobStore.Config(), disposal, true, false);
wacupdate.cellSchemaIsGenericFda = false;
wacupdate.CellStorageConfig = new CellStorageConfig();
wacupdate.Schema = CobaltFilePartition.Schema.ShreddedCobalt;
wacupdate.PartitionId = FilePartitionId.WordWacUpdate;
Dictionary<FilePartitionId, CobaltFilePartitionConfig> pd = new Dictionary<FilePartitionId, CobaltFilePartitionConfig>();
pd.Add(FilePartitionId.Content, content);
pd.Add(FilePartitionId.WordWacUpdate, wacupdate);
// custom locking store is my implementation of hostlockingstore
CobaltFile cobaltFile = new CobaltFile(disposal, pd, new CustomHostLockingStore(), null);
var src = FileAtom.FromExisting("C:\\tmp\\Test.docx", disposal);
Cobalt.Metrics o1;
cobaltFile.GetCobaltFilePartition(FilePartitionId.Content).SetStream(RootId.Default.Value, src, out o1);
cobaltFile.GetCobaltFilePartition(FilePartitionId.Content).GetStream(RootId.Default.Value).Flush();
cobaltFile.CommitChanges();
CobaltFile を取得したので、元の wopi コードを次のように編集できます。
}
else if (context.Request.HttpMethod.Equals(@"POST") && context.Request.Headers["X-WOPI-Override"].Equals("COBALT"))
{
Console.WriteLine(@"Got a cobalt request for the file");
var ms = new MemoryStream();
context.Request.InputStream.CopyTo(ms);
AtomFromByteArray atomRequest = new AtomFromByteArray(ms.ToArray());
RequestBatch requestBatch = new RequestBatch();
Object ctx;
ProtocolVersion protocolVersion;
requestBatch.DeserializeInputFromProtocol(atomRequest, out ctx, out protocolVersion);
cobaltFile.CobaltEndpoint.ExecuteRequestBatch(requestBatch);
cobaltFile.CommitChanges();
var response = requestBatch.SerializeOutputToProtocol(protocolVersion);
context.Response.Headers.Add("X-WOPI-MachineName", "test");
context.Response.Headers.Add("X-WOPI-CorellationID", context.Request.Headers["X-WOPI-CorrelationID"]);
context.Response.Headers.Add("request-id", context.Request.Headers["X-WOPI-CorrelationID"]);
context.Response.ContentType = @"application/octet-stream";
context.Response.ContentLength64 = response.Length;
response.CopyTo(context.Response.OutputStream);
context.Response.Close();
}
そしてcustomlockingstoreは近日公開予定です。細断処理からワード文書への変換はまだ行っていませんが、方法はわかっていると思います
最終更新 - 完全なソリューションは次のとおりです。
