我正在尝试在带有 Office 的浏览器中安装一个文档管理系统。我找到了这个解决方案http://www.edrawsoft.com/officeviewer.php，但它使用的是 office 的客户端副本。
我想使用 Office Web Apps，但我的问题是……我是否需要通过 SharePoint 或其他 Microsoft 产品使用它，或者我可以连接一个网站以在浏览器中为我自己的文档系统使用 Office Web Apps

您可以编写自己的实现 WOPI 协议的服务器，这将在查看/编辑模式下支持 PPTX/XSLX，仅在查看模式下支持 DOCX/PDF。 WOPI 服务器实现起来非常简单。
要编辑 word 文档，您需要实现 Cobalt 或 FSSHTTP/FSSHTTPB 协议。
另外不要忘记许可，Office Web Apps 要求所有用户都拥有有效的办公许可证。
这是一个示例 .NET WOPI 服务器：
调用它：

2014 年 6 月 13 日更新：
使用 Cobalt API 可以编辑 word 文档，尽管我的实现远非完美。让我们了解基础知识。 FSSHTTP 需要 Shredded Storage，SharePoint 在数据库中实现，但是在查看了 Cobalt Assembly 之后，我确定了在文件系统上创建碎文件的方法......这是相关代码的片段，这第一部分取自 c 的 word doc :\tmp\test.docx 并转换为 c:\tmp\filestore 和 c:\tmp\wacupdate 中的碎 blob
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();
现在你有了钴文件，你可以用这个来编辑我原来的 wopi 代码：
}
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();
}
customlockingstore 即将推出。从 shredded 转换回 word 文档我还没有做，但我想我知道怎么做
