\t\tWeb启动客户端服务软件并完成登录动作

在asp.net页面中增加一个按钮调用一个JavaScript函数实现启动程序
javascript:Run('客户端服务软件.exe -u admin -p 4f5a51484e3c639b7c0e606511fe062d5f55aa0509638b385ed179e6d7fe4e9b7342f04c7c74b625574d6aa009693f386cef7b49536c3a4bfb5372675e76bb134f746a84466b7da86703');
<script type="text/javascript" language="JavaScript">
function Run(command)
{
window.oldOnError = window.onerror;
window._command = command;
window.onerror = function (err){
if(err.indexOf('automation') != -1){
alert('命令已经被用户禁止！');
return true;
}
else return false;
};
try
{
var wsh = new ActiveXObject('WScript.Shell');
if(wsh)wsh.Run(command);
window.onerror=window.oldOnError;
}
catch (e)
{
alert(‘找不到文件EDNMS-DE.EXE(或它的组件之一)。请确定路径和文件名是否正确，而且所需的库文件均可用。‘)
}
}
</script>
为了使得Web端的Js能够调用"客户端服务软件.exe" 的Winform程序，我们需要在安装Winform的时候，把安装路径加入到操作系统Path变量中，操作系统的Path变量的内容放置在注册表节点SYSTEM\\ControlSet001\\Control\\Session Manager\\Environment的Path中.
处理命令行参数的公共类
using System;
using System.Collections.Generic;
using System.Text;

namespace WHC.EDNMS.Commons
{
public class CommandArgs
{
Dictionary<string, string> mArgPairs = new Dictionary<string,string>();
public Dictionary<string, string> ArgPairs
{
get { return mArgPairs; }
}

public List<string> Params
{
get { return mParams; }
}
List<string> mParams = new List<string>();
}

public class CommandLine
{
/// <summary>
/// Parses the passed command line arguments and returns the result
/// in a CommandArgs object.
/// </summary>
/// The command line is assumed to be in the format:
///
/// CMD [param] [[-|--|\]<arg>[[=]<value>]] [param]
///
/// Basically, stand-alone parameters can appear anywhere on the command line.
/// Arguments are defined as key/value pairs. The argument key must begin
/// with a ‘-‘, ‘--‘, or ‘\‘. Between the argument and the value must be at
/// least one space or a single ‘=‘. Extra spaces are ignored. Arguments MAY
/// be followed by a value or, if no value supplied, the string ‘true‘ is used.
/// You must enclose argument values in quotes if they contain a space, otherwise
/// they will not parse correctly.
///
/// Example command lines are:
///
/// cmd first -o outfile.txt --compile second \errors=errors.txt third fourth --test = "the value" fifth
///
/// <param name="args">array of command line arguments</param>
/// <returns>CommandArgs object containing the parsed command line</returns>
public static CommandArgs Parse(string[] args)
{
char[] kEqual = new char[] { ‘=‘ };
char[] kArgStart = new char[] { ‘-‘, ‘\\‘ };

CommandArgs ca = new CommandArgs();
int ii = -1;
string token = NextToken( args, ref ii );
while ( token != null )
{
if (IsArg(token))
{
string arg = token.TrimStart(kArgStart).TrimEnd(kEqual);

string value = null;

if (arg.Contains("="))
{
string[] r = arg.Split(kEqual, 2);
if ( r.Length == 2 && r[1] != string.Empty)
{
arg = r[0];
value = r[1];
}
}

while ( value == null )
{
string next = NextToken(args, ref ii);
if (next != null)
{
if (IsArg(next))
{
ii--;
value = "true";
}
else if (next != "=")
{
value = next.TrimStart(kEqual);
}
}
}

ca.ArgPairs.Add(arg, value);
}
else if (token != string.Empty)
{
ca.Params.Add(token);
}

token = NextToken(args, ref ii);
}

return ca;
}

static bool IsArg(string arg)
{
return (arg.StartsWith("-") || arg.StartsWith("\\"));
}

static string NextToken(string[] args, ref int ii)
{
ii++;
while ( ii < args.Length )
{
string cur = args[ii].Trim();
if (cur != string.Empty)
{
return cur;
}
ii++;
}

return null;
}

}
}
然后在程序的入口Main函数中，增加对参数化的登录解析，如下所示:
[STAThread]
static void Main(string[] args)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);

if (args.Length > 0)
{
//args = new string[] { "-u ", "admin", "-p", "4e0a40090737639a661f6e7109f1062c585dff410f668c3c5f836caf8ef54e9a695bfe48647bb62450457fe40b6c383c6dbd6e0002673a4ae14a74634679bb12487c7fc0406e7aac6611" };
LoginByArgs(args);
}
else
{
LoginNormal(args);
}
}
/// <summary>
/// 使用参数化登录
/// </summary>
/// <param name="args"></param>
private static void LoginByArgs(string[] args)
{
CommandArgs commandArgs = CommandLine.Parse(args);
if (commandArgs.ArgPairs.Count > 0)
{
#region 获取用户参数
string userName = string.Empty;
string identity = string.Empty;
foreach (KeyValuePair<string, string> pair in commandArgs.ArgPairs)
{
if ("U".Equals(pair.Key, StringComparison.OrdinalIgnoreCase))
{
userName = pair.Value;
}
if ("P".Equals(pair.Key, StringComparison.OrdinalIgnoreCase))
{
identity = pair.Value;
}
}
#endregion

if (!string.IsNullOrEmpty(userName) && !string.IsNullOrEmpty(identity))
{
bool bLogin = 登录验证方法(userName.Trim(), identity);
if (bLogin)
{
ShowMainDialog();
}
else
{
LoginNormal(args);
}
}
}
}
