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<br /> {<br /> using System;<br /> using System.Net;<br /> using System.Runtime.InteropServices;<br /> using System.Threading;<br /> using System.Windows.Forms;</p> <p> internal static class Program<br /> {<br /> private const int BUFSIZE = 0x3e8;<br /> private const int TOKEN_ADJUST_PRIVILEGES = 0x20;<br /> private const int TOKEN_QUERY = 8;</p> <p> [DllImport("kernel32.dll", ExactSpelling=true)]<br /> internal static extern IntPtr GetCurrentProcess();<br /> [DllImport("advapi32", CharSet=CharSet.Auto)]<br /> private static extern bool GetTokenInformation(IntPtr hToken, TOKEN_INFORMATION_CLASS tokenInfoClass, IntPtr TokenInformation, int tokeInfoLength, ref int reqLength);<br /> [STAThread]<br /> private static void Main(string[] args)<br /> {<br /> Thread.CurrentThread.Name = "Imps.Client.Pc MainThread";<br /> Application.EnableVisualStyles();<br /> ServicePointManager.MaxServicePointIdleTime = 0x7530;<br /> try<br /> {<br /> IntPtr currentProcess = GetCurrentProcess();<br /> IntPtr zero = IntPtr.Zero;<br /> if (!OpenProcessToken(currentProcess, 40, ref zero))<br /> {<br /> goto Label_008C;<br /> }<br /> IntPtr tokenInformation = Marshal.AllocHGlobal(0x3e8);<br /> int tokeInfoLength = 0x3e8;<br /> GetTokenInformation(zero, TOKEN_INFORMATION_CLASS.TokenPrivileges, tokenInformation, tokeInfoLength, ref tokeInfoLength);<br /> TokPriv1Luid luid = (TokPriv1Luid) Marshal.PtrToStructure(tokenInformation, typeof(TokPriv1Luid));<br /> if (luid.Count > 1)<br /> {<br /> goto Label_008C;<br /> }<br /> MessageBox.Show("运行此程序的权限不够！");<br /> }<br /> catch<br /> {<br /> }<br /> return;<br /> Label_008C:<br /> Application.SetCompatibleTextRenderingDefault(false);<br /> Application.Run(new MainForm(args));<br /> }</p> <p> [DllImport("advapi32.dll", SetLastError=true, ExactSpelling=true)]<br /> internal static extern bool OpenProcessToken(IntPtr h, int acc, ref IntPtr phtok);</p> <p> private enum TOKEN_INFORMATION_CLASS<br /> {<br /> TokenDefaultDacl = 6,<br /> TokenGroups = 2,<br /> TokenImpersonationLevel = 9,<br /> TokenOwner = 4,<br /> TokenPrimaryGroup = 5,<br /> TokenPrivileges = 3,<br /> TokenRestrictedSids = 11,<br /> TokenSessionId = 12,<br /> TokenSource = 7,<br /> TokenStatistics = 10,<br /> TokenType = 8,<br /> TokenUser = 1<br /> }</p> <p> [StructLayout(LayoutKind.Sequential, Pack=1)]<br /> internal struct TokPriv1Luid<br /> {<br /> public int Count;<br /> public long Luid;<br /> public int Attr;<br /> }<br /> }<br /> }</p> <p>  

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!

            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。
