中国移动飞信的研究 笔记二

中国移动飞信的研究 笔记二

经过 上一篇 的查看飞信 里面 封装了不少。 这里面不仅是一层加一层，而且是这一层还调用另外的程序集。类与类之间的组合、继承可谓是 很复杂。到底从哪里下手呢。 我本次研究 也不是为了彻底的研究它，也就是他的一些基本功能的研究。顺便，将一些类弄清楚。最后还是按照程序的 运行顺序一步一步的来研究吧。按照功能分析。

声明：个人并非侵犯 移动公司的权益。此笔记纯属个人学习的记录。若移动不同意，我立马将这些文档删除！希望各位见谅！

下面就将程序的包含主函数的Program 发出来：

namespace Imps.Client.Pc
{
using System;
using System.Net;
using System.Runtime.InteropServices;
using System.Threading;
using System.Windows.Forms;

internal static class Program
{
private const int BUFSIZE = 0x3e8;
private const int TOKEN_ADJUST_PRIVILEGES = 0x20;
private const int TOKEN_QUERY = 8;

[DllImport("kernel32.dll", ExactSpelling=true)]
internal static extern IntPtr GetCurrentProcess();
[DllImport("advapi32", CharSet=CharSet.Auto)]
private static extern bool GetTokenInformation(IntPtr hToken, TOKEN_INFORMATION_CLASS tokenInfoClass, IntPtr TokenInformation, int tokeInfoLength, ref int reqLength);
[STAThread]
private static void Main(string[] args)
{
Thread.CurrentThread.Name = "Imps.Client.Pc MainThread";
Application.EnableVisualStyles();
ServicePointManager.MaxServicePointIdleTime = 0x7530;
try
{
IntPtr currentProcess = GetCurrentProcess();
IntPtr zero = IntPtr.Zero;
if (!OpenProcessToken(currentProcess, 40, ref zero))
{
goto Label_008C;
}
IntPtr tokenInformation = Marshal.AllocHGlobal(0x3e8);
int tokeInfoLength = 0x3e8;
GetTokenInformation(zero, TOKEN_INFORMATION_CLASS.TokenPrivileges, tokenInformation, tokeInfoLength, ref tokeInfoLength);
TokPriv1Luid luid = (TokPriv1Luid) Marshal.PtrToStructure(tokenInformation, typeof(TokPriv1Luid));
if (luid.Count > 1)
{
goto Label_008C;
}
MessageBox.Show("运行此程序的权限不够！");
}
catch
{
}
return;
Label_008C:
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainForm(args));
}

[DllImport("advapi32.dll", SetLastError=true, ExactSpelling=true)]
internal static extern bool OpenProcessToken(IntPtr h, int acc, ref IntPtr phtok);

private enum TOKEN_INFORMATION_CLASS
{
TokenDefaultDacl = 6,
TokenGroups = 2,
TokenImpersonationLevel = 9,
TokenOwner = 4,
TokenPrimaryGroup = 5,
TokenPrivileges = 3,
TokenRestrictedSids = 11,
TokenSessionId = 12,
TokenSource = 7,
TokenStatistics = 10,
TokenType = 8,
TokenUser = 1
}

[StructLayout(LayoutKind.Sequential, Pack=1)]
internal struct TokPriv1Luid
{
public int Count;
public long Luid;
public int Attr;
}
}
}

此程序里引用了 Windows的API。

引用这些API 据我 查看应该是 保证程序有足够的 权限来运行！

由 Application.Run(new MainForm(args)); 可以看出，首先是调用了主界面 MainForm。

其中，args 为传递过来的参数。

下面是 MainForm的源代码: 由于程序源代码多大 3200多行，IE打开会很慢，所以只列出重要代码!

this.WM_FETIONSTARTED = (int) Imps.Client.Utils.Win32.NativeMethods.RegisterWindowMessage("FetionStarted");
CallMe.InitCallMe(this);
CallMeHelper.WM_FETION_CALLME = (int) Imps.Client.Utils.Win32.NativeMethods.RegisterWindowMessage("FetionCallMeMessage");
if (this.TryCheckSingleton())
{
CallMeHelper.TrySendCallMeMessage(args, base.Handle);
Environment.Exit(0);
}
else
{
if (this.ExistFetionInstance())
{
if (CallMeHelper.TrySendCallMeMessage(args, base.Handle))
{

return;
}
}
else if (args.Length >= 1)
{
foreach (string str in args)
{

{
break;
}
}
}
try
{

this.trayIcon.Icon = ImpsTrayIcons.OffLine;

this.trayIcon.Visible = true;
this.DoLocalization();
this.RearrangeUiElements();
this.TryLoadWindowsSetting(this);
if (!this.CurrentUser.Configuration.UserSetting.MainWindowSetting.AutoPopup)
{
base.WindowState = FormWindowState.Minimized;
if (UserAccounts.LatestAccountAutoLogin)
{
base.ShowInTaskbar = false;
}
}
ImpsHelp.HelpPage = Imps.Client.Core.FixedClientSetting.Instance.HelpPage;
this.CurHandleRef = new HandleRef(this, base.Handle);
this.RegWndMsg();
}
catch (Exception exception)
{
MessageBox.Show(exception.Message);
ShellHelper.ApplicationExit();
}
}
}
...
...

}
}

if (this.TryCheckSingleton())
{
CallMeHelper.TrySendCallMeMessage(args, base.Handle);
Environment.Exit(0);
}
else
{
if (this.ExistFetionInstance())
{
if (CallMeHelper.TrySendCallMeMessage(args, base.Handle))
{
Environment.Exit(0);
return;
}
}

这里可以看出 飞信程序一台机器只能登陆一个。保证了程序的唯一性。

由于主界面里功能很复杂，篇幅太长这里就不解释了。
