[C#.NET][Sharepoint 2013] 如何使用 REST API 上傳檔案 for X-RequestDigest header
續上篇,http://www.dotblogs.com.tw/yc421206/archive/2014/06/12/145512.aspx
本文章節
根據下圖,新增檔案需要:
2.使用 HttpMethod.Post
3.根據 http://msdn.microsoft.com/en-us/library/office/jj164022%28v=office.15%29.aspx#bk_requestElements 所述 ,使用 OAuth 選 Authentication header ;反之選 X-RequestDigest header,本篇使用 X-RequestDigest header
取得 FormDigestValue for Advanced REST client
整個資料取得的方式並不困難,這裡使用了Linq to Json (Json.NET from NuGet)將 FormDigestValue 拿出來
{ HttpClientHandler httpClientHandler = new HttpClientHandler() { Credentials = new NetworkCredential(YourId, YourPassword, YourDomain) }; using (var httpClient = new HttpClient(httpClientHandler)) { httpClient.BaseAddress = new Uri("http://sps2013"); httpClient.DefaultRequestHeaders.Add("Accept", "application/json;odata=verbose"); HttpResponseMessage response = httpClient.PostAsync("/_api/contextinfo", null).Result; HttpRequestMessage a = new HttpRequestMessage(); a.Method = HttpMethod.Post; if (response.StatusCode == HttpStatusCode.OK) { var result = response.Content.ReadAsStringAsync().Result; JObject jsonObject = JObject.Parse(result); var formDigestValue = jsonObject.Descendants() .OfType<JProperty>().First(p => p.Name == "FormDigestValue") .Value; return formDigestValue.ToString(); } return null; } }
最重要的是要帶入 X-RequestDigest header
{ HttpClientHandler httpClientHandler = new HttpClientHandler() { Credentials = new NetworkCredential(YourId, YourPassword, YourDomain) }; using (var httpClient = new HttpClient(httpClientHandler)) { httpClient.BaseAddress = new Uri("http://sps2013/CsomApi"); httpClient.DefaultRequestHeaders.Add("Accept", "application/json;odata=verbose"); httpClient.DefaultRequestHeaders.Add("X-RequestDigest", GetFormDigestValue()); FileStream uploadStream = new FileStream("myDoc.docx", FileMode.Open, FileAccess.Read); HttpContent uploadContent = new StreamContent(uploadStream); HttpResponseMessage response = httpClient.PostAsync( "/_api/Web/GetFolderByServerRelativeUrl('Shared%20Documents')/Files/add(url='myDoc.docx',overwrite=true)", uploadContent).Result; if (response.StatusCode == HttpStatusCode.OK) { var result = response.Content.ReadAsStringAsync().Result; Console.WriteLine(result); } Console.WriteLine("successful down file,please press any key contiune"); Console.ReadKey(); } }
