我正在编写一个 DLL,它具有无需使用用户密码、仅使用用户主体名称 (UPN) 即可获取 Alfresco 登录票证的功能。我正在调用露天 REST API 服务/wc服务。我在 Alfresco 中使用 NTLM。
我冒充用户使用WindowsIdentity
构造函数如此处解释http://msdn.microsoft.com/en-us/library/ms998351.aspx#paght000023_impersonatingbyusingwindowsidentity http://msdn.microsoft.com/en-us/library/ms998351.aspx#paght000023_impersonatingbyusingwindowsidentity。我检查过并且用户被正确模拟(我检查过WindowsIdentity.GetCurrent().Name
财产)。
冒充用户后,我尝试制作HttpWebRequest
并设置其凭据CredentialsCache.DefaultNetworkCredentials
。我收到错误:
The remote server returned an error: (401) Unauthorized.
at System.Net.HttpWebRequest.GetResponse()
当我使用new NetworkCredential("username", "P@ssw0rd")
要设置请求凭据,我获得了 Alfresco 登录票证(HttpStatusCode.OK
, 200).
有什么方法可以在没有用户密码的情况下获得 Alfresco 登录票吗?
这是我正在使用的代码:
private string GetTicket(string UPN) {
WindowsIdentity identity = new WindowsIdentity(UPN);
WindowsImpersonationContext context = null;
try {
context = identity.Impersonate();
MakeWebRequest();
}
catch (Exception e) {
return e.Message + Environment.NewLine + e.StackTrace;
}
finally {
if (context != null) {
context.Undo();
}
}
}
private string MakeWebRequest() {
string URI = "http://alfrescoserver/alfresco/wcservice/mg/util/login";
HttpWebRequest request = WebRequest.Create(URI) as HttpWebRequest;
request.CookieContainer = new CookieContainer(1);
//request.Credentials = new NetworkCredential("username", "p@ssw0rd"); // It works with this
request.Credentials = CredentialCache.DefaultNetworkCredentials; // It doesn’t work with this
//request.Credentials = CredentialCache.DefaultCredentials; // It doesn’t work with this either
try {
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) {
StreamReader sr = new StreamReader(response.GetResponseStream());
return sr.ReadToEnd();
}
}
catch (Exception e) {
return (e.Message + Environment.NewLine + e.StackTrace);
}
}
以下是来自 Alfresco stdout.log 的记录(如果有任何帮助的话):
