我使用以下教程创建了一个应用程序:
http://www.luisevalencia.com/2014/07/23/prepare-environments-sharepoint-provider-hosted-apps/
如果没有共享点调用,该应用程序可以完美运行,我的意思是带有 hello world 的 response.write 可以正常工作。
但是,如果我添加一些共享点的东西,比如打印出用户名,我会得到一个远程服务器返回错误:(401)未经授权。
Uri hostWeb = new Uri(Request.QueryString["SPHostUrl"]);
using (var clientContext = TokenHelper.GetS2SClientContextWithWindowsIdentity(hostWeb, Request.LogonUserIdentity))
{
clientContext.Load(clientContext.Web, web => web.Title);
clientContext.ExecuteQuery();
Response.Write(clientContext.Web.Title);
Response.Write("Hello World");
}
我在日志中收到以下错误。
