我想在带有 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 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，或者我是否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
最佳答案
您可以编写自己的实现 WOPI 协议(protocol)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(protocol)。
另外不要忘记许可，Office Web Apps 要求所有用户都拥有有效的 office 许可证。
这是一个示例 .NET WOPI 服务器:

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 Cobalt Assembly 之后我确定了在文件系统上创建一个碎片文件的方法......这是相关代码的片段，第一部分从 c 中获取 word doc :\tmp\test.docx 并在 c:\tmp\filestore 和 c:\tmp\wacupdate 中转换为切碎的 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 cobaltFile，你可以用这个编辑我原来的 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();
}
和定制锁店即将推出。从切碎的文档转换回 word 文档我还没有做过，但我想我知道怎么做
