C＃webbrowser控制和模拟 [英] C# webbrowser control and impersonation

问题描述

嗨朋友



我的问题背景是我必须为部门中的其他人提供的监控解决方案（SCOM）。



我希望我能够看到每个用户组的其他人所能看到的相同内容。由于我正在与其他人一起工作，我总是有额外的工作，我可以看到他们在有限的权利中可以看到什么。



我现在想创建一个小应用程序（winform），它允许我在一个应用程序中观察所有不同组的网页观点。所有结果集都在同一个网页上，但对于用户而言则不同。



我喜欢做的是：

- 创建一个带有每个用户组标签的应用程序。

- 为每个用户组配置一个虚拟帐户，该帐户与该组用户具有相同的权限（实际上是同一个Windows组的成员）

- 现在创建一个webbrowser控件并使用虚拟账户的凭证



我想到的解决方案：

- 创建一个usercontrol，它将接受构造函数的URL， usernamen和密码

- 在运行时读取配置并为每个项目创建一个带有usercontrol的选项卡



问题：

如何在不同的安全上下文中创建usercontrol？

我试图使用UriBuilder的用户名和密码，但结果根本不起作用。



有没有人有想法？



最好的问候

Dirk

解决方案

组合来自2个链接的代码：

使用C＃在Windows中访问受密码保护的网络驱动器？

在C＃.NET中进行完整的模拟演示

并执行以下步骤

  //   1。登录 
  IntPtr 令牌; 
  IntPtr  tokenD; 
  if （！NativeMethods。 LogonUser （login.User，login.Domain，login.Password，LogonType.Interactive，LogonProvider。默认， out 令牌））
  throw   new  Win32Exception（）; 
  if （！NativeMethods。 DuplicateToken （token，SecurityImpersonationLevel.Impersonation， out  tokenD））
  throw   new  Win32Exception（）; 
 
  //   2。剖析。您需要管理员或本地帐户才能运行LoadUserProfile  
 ProfileInfo profileInfo =  new  ProfileInfo（）; 
 profileInfo.dwSize = Marshal.SizeOf（profileInfo）; 
 profileInfo.lpUserName = login.User; 
 profileInfo.dwFlags =  1 ; 
  if （！NativeMethods。 LoadUserProfile （tokenD， ref  profileInfo ））
  throw   new  Win32Exception（）; 
 
  //   3。模拟 
  var  identity =  new  WindowsIdentity（tokenD）; 
  var  context = identity.Impersonate（）; 
 
  //   5。创建浏览器 
  var  browser =  new   WebBrowser  （）; 
 browser.Tag = context; 
 browser.Navigate（ new  Uri（  http://www.codeproject.com））; 
 
  //   6。在用户之后处理，可以在WebBrowser.Disposing或在选项卡上进行尝试选择事件 
 NativeMethods。 CloseHandle （tokenD）; 
 NativeMethods。 CloseHandle （令牌）; 
 NativeMethods。 UnloadUserProfile （tokenD，profile.hProfile）; 
 context.Undo（）; 
 

这个老问题。也许你有另一种解决方案？如果是，请发布。

Hi friends

Background of my question is a monitoring solution (SCOM) that I have to provide for others in the department.

I like to have the possibility that I can see the same what the other employes of each usergroup can see. As I'm working with more rights as the others I always have extra work that I can see what they with the limited rights can see.

I'm like to create now a small application (winform) that allows me to observe the webpage for all of the different groups in a single application with all the different point of views. All the resultsets are on the same webpage but are different for the users.

What I like to do is:
- creating an application with a tab for each usergroup.
- configure for each usergroup a "dummy" account that has the same rights as the users of the group (in fact is a member of the same windows group)
- now create a webbrowser control and using the credentials of the dummy account

Solution that I have in mind:
- creating an usercontrol that will take in the constructor the URL, the usernamen and the password
- on runtime read the configurations and create for each of the items a tab with the usercontrol

Problem:
How can I create the usercontrol in a different security context?
I was trying to use the UriBuilder with username and password but the result was not working at all.

Has anyone an idea?

best regards
Dirk

解决方案

Combine code from 2 links:
Accessing Password Protected Network Drives in Windows in C#?
A complete Impersonation Demo in C#.NET
And do folowing steps

//1. Logining
IntPtr token;
IntPtr tokenD;
if (!NativeMethods.LogonUser(login.User, login.Domain, login.Password, LogonType.Interactive, LogonProvider.Default, out token))
    throw new Win32Exception();
if (!NativeMethods.DuplicateToken(token, SecurityImpersonationLevel.Impersonation, out tokenD))
    throw new Win32Exception();

//2. Profiling. You nead administranor or local account to run LoadUserProfile
ProfileInfo profileInfo = new ProfileInfo();
profileInfo.dwSize = Marshal.SizeOf(profileInfo);
profileInfo.lpUserName = login.User;
profileInfo.dwFlags = 1;
if(!NativeMethods.LoadUserProfile(tokenD, ref profileInfo))
    throw new Win32Exception();

//3. Impersonating
var identity = new WindowsIdentity(tokenD);
var context = identity.Impersonate();

//5. Create Browser
var browser = new WebBrowser();
browser.Tag = context;
browser.Navigate(new Uri("http://www.codeproject.com"));

//6. Dispose after user, can bee on WebBrowser.Disposing or try it on tabs Selection event
NativeMethods.CloseHandle(tokenD);
NativeMethods.CloseHandle(token);
NativeMethods.UnloadUserProfile(tokenD, profile.hProfile);
context.Undo();

Its old question. Maybe you have another solution? If so, please post it.
