从 Web 访问 Sharepoint 2013 网站 api
Access to sharepoint 2013 site from web api
我正在研究用 c# 和打字稿开发的 MVC 网络应用程序与远程共享点站点之间的通信。我想对 excel 文件执行 crud 操作。
我可以通过这种方式读取站点属性:
public async Task<string> getWebTitle(string webUrl, string usr, string psw)
{
//Creating Password
const string PWD = psw;
const string USER = usr;
const string RESTURL = "{0}/_api/web?$select=Title";
//Creating Credentials
var passWord = new SecureString();
foreach (var c in PWD) passWord.AppendChar(c);
var credential = new SharePointOnlineCredentials(USER, passWord);
//Creating Handler to allows the client to use credentials and cookie
using (var handler = new HttpClientHandler() { Credentials = credential })
{
//Getting authentication cookies
Uri uri = new Uri(webUrl);
handler.CookieContainer.SetCookies(uri, credential.GetAuthenticationCookie(uri));
//Invoking REST API
using (var client = new HttpClient(handler))
{
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await client.GetAsync(string.Format(RESTURL, webUrl)).ConfigureAwait(false);
response.EnsureSuccessStatusCode();
string jsonData = await response.Content.ReadAsStringAsync();
return jsonData;
}
}
}
jsonData 对象 returns 站点属性。
如何读取保存在 "mysite" 的文档文件夹中的文件,例如 test.txt?
您的意思是要获取 SharePoint 中文件的内容吗?
我们可以使用CSOM来实现。
这里有一个示例供您参考:
public static void getContentOfFileInDocLib(string siteUrl, string host, string sourceListName, string fileName)
{
siteUrl = siteUrl.EndsWith("/") ? siteUrl.Substring(0, siteUrl.Length - 1) : siteUrl;
ClientContext context = new ClientContext(siteUrl);
Web web = context.Site.RootWeb;
List source = web.Lists.GetByTitle(sourceListName);
context.Load(source);
context.Load(web);
context.ExecuteQuery();
FileCollection files = source.RootFolder.Files;
Microsoft.SharePoint.Client.File file = files.GetByUrl(siteUrl + "/" + sourceListName + "/" + fileName);
context.Load(file);
context.ExecuteQuery();
FileInformation fileInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(context, file.ServerRelativeUrl);
string filePath = host + file.ServerRelativeUrl;
System.IO.Stream fileStream = fileInfo.Stream;
FileCreationInformation createFile = new FileCreationInformation();
byte[] bufferByte = new byte[1024 * 100];
System.IO.MemoryStream memory = new System.IO.MemoryStream();
int len = 0;
while ((len = fileStream.Read(bufferByte, 0, bufferByte.Length)) > 0)
{
memory.Write(bufferByte, 0, len);
}
//we get the content of file here
byte[] bytes = memory.GetBuffer();
//do something you want
//.......
}
将文件上传到 SharePoint 文档库。
public static void uploadFile(string siteUrl, string filePath, string fileName, string docLibName)
{
siteUrl = siteUrl.EndsWith("/") ? siteUrl.Substring(0, siteUrl.Length - 1) : siteUrl;
ClientContext context = new ClientContext(siteUrl);
List docLib = context.Web.Lists.GetByTitle(docLibName);
context.Load(docLib);
context.ExecuteQuery();
Byte[] bytes = System.IO.File.ReadAllBytes(filePath + fileName);
FileCreationInformation createFile = new FileCreationInformation();
createFile.Content = bytes;
createFile.Url = siteUrl + "/" + docLibName + "/" + fileName;
createFile.Overwrite = true;
Microsoft.SharePoint.Client.File newFile = docLib.RootFolder.Files.Add(createFile);
newFile.ListItemAllFields.Update();
context.ExecuteQuery();
}
