WOPI Editing Document

Question

I have implemented the putFile endpoint for WOPI client (i.e. Office Online) When clicking the edit document button, what should be the first request go to WOPI client?

I have called following URL on edit link:

POST https://word-edit.officeapps-df.live.com/we/wordviewerframe.aspx?WOPISrc=https://domain/WOPI_IntegrationDemo/wopi/files/Sample_application_content3.docx/

But document says that it'll perform a lock request first. What does it mean exactly?

From your question I understand that you're implementing a WOPI host. The URL looks pretty much ok - just make sure the WOPISrc parameter is escaped and that you include access_token parameter.

When you click the URL you instruct the WOPI client (OO/OWA) to load a field defined by WOPISrc from WOPI host.

The WOPI client usually tries to acquire a lock (exclusive write access) from WOPI host first. For those purposes you should implement the LOCK operation in your WOPI host according to the documentation.

First you must Add Access token for this then you try to word edit it call to 1.get file info. Get [Route("files/{name}/")] 2.post file. Post [Route("files/{name}/")] in hear you have to implement response for Lock files Cobalt Request var response = new HttpResponseMessage(HttpStatusCode.OK); if (xWopiOverride == "LOCK" || string.Equals(xWopiOverride, "UNLOCK")) { //for docx, xlsx and pptx response = new HttpResponseMessage(HttpStatusCode.OK); } else if (string.Equals(xWopiOverride, "COBALT")) { //cobalt, for docx and pptx

                EditSession editSession = EditSessionManager.Instance.GetSession(access_token);
                if (editSession == null)
                {
                    editSession = new FileSession(access_token, fileInfo, matterInfo, dpsUserName, databaseInfo, string.Empty, string.Empty, string.Empty, false);
                    EditSessionManager.Instance.AddSession(editSession);
                }

                var memoryStream = new MemoryStream();
                HttpContext.Current.Request.InputStream.CopyTo(memoryStream);
                var atomFromByteArray = new AtomFromByteArray(memoryStream.ToArray());

                ProtocolVersion protocolVersion;
                object context;
                var requestBatch = new RequestBatch();
                requestBatch.DeserializeInputFromProtocol(atomFromByteArray, out context, out protocolVersion);
                editSession.ExecuteRequestBatch(requestBatch);

                foreach (var request in requestBatch.Requests)
                {
                    if (request.GetType() == typeof(PutChangesRequest) && request.PartitionId == FilePartitionId.Content)
                    {
                        editSession.Save();
                        break;
                    }
                }

                var responseContent = requestBatch.SerializeOutputToProtocol(protocolVersion, context);
                var correlationId = Request.Headers.GetValues("X-WOPI-CorrelationID").First();

                response.Headers.Add("X-WOPI-CorrelationID", correlationId);
                response.Headers.Add("request-id", correlationId);

                var pushStreamContent = new PushStreamContent((outputStream, httpContext, transportContent) =>
                {
                    responseContent.CopyTo(outputStream);
                    outputStream.Close();
                });

                response.Content = pushStreamContent;
                response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
                response.Content.Headers.ContentLength = responseContent.Length;
            }
            return response;
