Asp.net MVC 开发对接 Office Online Server
本文章对接接口开发参考：
routes.MapRoute( name: "filesGet", url: "wopi/files/{id}", defaults: new { controller = "openapi", action = "filesGet", id = UrlParameter.Optional } ); routes.MapRoute( name: "filesPost", url: "wopi/files/{id}/contents", defaults: new { controller = "openapi", action = "files", id = UrlParameter.Optional } );
public class openapiController : Controller { /// <summary> /// officeserver 获取文件内容Get、回传修改后的文件内容Post /// </summary> /// <param name="id"></param> /// <returns></returns> public ActionResult files(string id) { if (Request.RequestType.ToUpper() == "GET") { string FilePath = Server.MapPath("~/App_Data/"+ id); byte[] data = System.IO.File.ReadAllBytes(FilePath); return File(data, @"application/octet-stream", id); } else { byte[] b = new byte[Request.InputStream.Length]; Request.InputStream.Read(b, 0, b.Length); // 设置当前流的位置为流的开始 Request.InputStream.Seek(0, SeekOrigin.Begin); string FilePath = Server.MapPath("~/App_Data/" + id); using (FileStream fs = System.IO.File.Create(FilePath)) { fs.Write(b,0,b.Length); } return Content("OK"); } } /// <summary> /// 校验文件信息获取合法性 /// </summary> /// <param name="id"></param> /// <returns></returns> public ActionResult filesGet(string id) { WopiCheckFileInfo cfi = new WopiCheckFileInfo(); string FilePath = Server.MapPath("~/App_Data/"+id); byte[] data = System.IO.File.ReadAllBytes(FilePath); FileInfo f = new FileInfo(FilePath); cfi.BaseFileName = id; cfi.OwnerId = "Anonymous"; cfi.UserFriendlyName = "Anonymous"; cfi.Size = data.Length; cfi.Version = DateTime.Now.ToString("s"); cfi.SupportsCoauth = false; cfi.SupportsCobalt = false; cfi.SupportsFolders = true; cfi.SupportsLocks = true; cfi.SupportsScenarioLinks = false; cfi.SupportsSecureStore = false; cfi.SupportsUpdate = true; cfi.UserCanWrite = true; return this.Json(cfi, JsonRequestBehavior.AllowGet); } } [DataContract] public class WopiCheckFileInfo { [DataMember] public bool AllowExternalMarketplace { get; set; } [DataMember] public string BaseFileName { get; set; } [DataMember] public string BreadcrumbBrandName { get; set; } [DataMember] public string BreadcrumbBrandUrl { get; set; } [DataMember] public string BreadcrumbDocName { get; set; } [DataMember] public string BreadcrumbDocUrl { get; set; } [DataMember] public string BreadcrumbFolderName { get; set; } [DataMember] public string BreadcrumbFolderUrl { get; set; } [DataMember] public string ClientUrl { get; set; } [DataMember] public bool CloseButtonClosesWindow { get; set; } [DataMember] public string CloseUrl { get; set; } [DataMember] public bool DisableBrowserCachingOfUserContent { get; set; } [DataMember] public bool DisablePrint { get; set; } [DataMember] public bool DisableTranslation { get; set; } [DataMember] public string DownloadUrl { get; set; } [DataMember] public string FileSharingUrl { get; set; } [DataMember] public string FileUrl { get; set; } [DataMember] public string HostAuthenticationId { get; set; } [DataMember] public string HostEditUrl { get; set; } [DataMember] public string HostEmbeddedEditUrl { get; set; } [DataMember] public string HostEmbeddedViewUrl { get; set; } [DataMember] public string HostName { get; set; } [DataMember] public string HostNotes { get; set; } [DataMember] public string HostRestUrl { get; set; } [DataMember] public string HostViewUrl { get; set; } [DataMember] public string IrmPolicyDescription { get; set; } [DataMember] public string IrmPolicyTitle { get; set; } [DataMember] public string OwnerId { get; set; } [DataMember] public string PresenceProvider { get; set; } [DataMember] public string PresenceUserId { get; set; } [DataMember] public string PrivacyUrl { get; set; } [DataMember] public bool ProtectInClient { get; set; } [DataMember] public bool ReadOnly { get; set; } [DataMember] public bool RestrictedWebViewOnly { get; set; } [DataMember] public string SHA256 { get; set; } [DataMember] public string SignoutUrl { get; set; } [DataMember] public long Size { get; set; } [DataMember] public bool SupportsCoauth { get; set; } [DataMember] public bool SupportsCobalt { get; set; } [DataMember] public bool SupportsFolders { get; set; } [DataMember] public bool SupportsLocks { get; set; } [DataMember] public bool SupportsScenarioLinks { get; set; } [DataMember] public bool SupportsSecureStore { get; set; } [DataMember] public bool SupportsUpdate { get; set; } [DataMember] public string TenantId { get; set; } [DataMember] public string TermsOfUseUrl { get; set; } [DataMember] public string TimeZone { get; set; } [DataMember] public bool UserCanAttend { get; set; } [DataMember] public bool UserCanNotWriteRelative { get; set; } [DataMember] public bool UserCanPresent { get; set; } [DataMember] public bool UserCanWrite { get; set; } [DataMember] public string UserFriendlyName { get; set; } [DataMember] public string UserId { get; set; } [DataMember] public string Version { get; set; } [DataMember] public bool WebEditingDisabled { get; set; } }

以上链接为请求office online server 打开一个在线文档。
http%3A%2F%2Fsp.dev.website.com%2Fwopi%2Ffiles%2FMEF100a.xlsx 此参数为对应的连接地址；
office online server 在打开时会发起两次Get请求：（请注意此时的请求都是GET）
第一次请求： http://sp.dev.website.com/wopi/files/MEF100a.xlsx , 对应的路由就是 url: "wopi/files/{id}" 对应的 openapiController.filesGet . 用于验证文件是否可取，服务器端需要返回相关的文件信息
第二次请求： http://sp.dev.website.com/wopi/files/MEF100a.xlsx/contents ,对应的路由就是 url: "wopi/files/{id}/contents" 对应的 openapiController.files ，获取文件流。
office online server 在存档时，会发起POST请求，把文件内容传回原来的服务器。
POST请求： http://sp.dev.website.com/wopi/files/MEF100a.xlsx/contents , ,对应的路由就是 url: "wopi/files/{id}/contents" 对应的 openapiController.files ，上传文件流。
本文代码只是简单的文件获取 ，没有对文件的访问做权限验证、存档权限验证等，若有需要可在Action的访问添加相关参数。
