【问题标题】:Execute EXE with JavaScript用 JavaScript 执行 EXE
【发布时间】:2018-04-12 19:29:15
【问题描述】:

我的公司有一个旧的 Windows 窗体 VB 应用程序,它允许用户更新他们的 Outlook 签名。我最近在C# 中重新编写了该应用程序,现在正在尝试复制他们的分发技术,但遇到了错误。

他们创建了一个ASPX 页面,其中只包含一个JavaScript 函数来执行EXE,见下文:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script language="javascript" >
    function todo() {
        //window.open('', '_self', '');
        //window.close();
        var theShell = new ActiveXObject("Shell.Application");
        var theApp = "S:\\web\\EMS_2013\\EmailSignature1_2013.exe";
        theShell.ShellExecute(theApp, "", "", "open", "1");
        window.opener = ''
        window.close();
    }    
</script>

</head>
<body onload="window.opener='';todo()">
</body>
</html>

如何将此功能转换为基于 C# 而不是 VB?对于初学者,我怎样才能获得网页JS功能以Debug模式在本地打开EXE?

我对 VB 的了解仅限于我可以对这些旧应用程序进行逆向工程,并且我们正试图摆脱 VB,因此理想情况下,这个简单的应用程序也能得到转换。

在我的研究中,我一直在努力寻找如何做到这一点的解释,因为共识是安全设置会阻止 Web 浏览器在客户端计算机上运行 EXE。但是这个应用程序正在这样做。

我创建了一个简单的 .NET Web 应用程序并重新创建了 HTML / Javascript 端,但我什至无法让它在本地执行 EXE,并且 VB 应用程序已部署到 IIS 服务器。

我不知道如何继续...在尝试部署到我的 IIS 服务器之前,我是否应该能够从 Web 浏览器以调试模式执行 EXE?是否有其他技术可以让我为用户运行 EXE 而不会收到任何确认提示?

这是VB 应用程序的web.config 文件的内容,我的文化程度不高,无法理解其中的内容

【问题讨论】:

  • 可能是浏览器上的一条规则,说这个特定的url可以运行这个特定的可执行文件。
  • 您向我们展示的内容恐怕不是很清楚。第一个代码 sn-p 只显示 Javascript 代码,而不是 VB(尽管它确实表明后面的代码是 VB)。当他们打开这个页面时,你是否试图让这个可执行文件在客户端机器上运行?
  • 正确,按照我的理解,这个 Default.aspx 页面位于 IIS 服务器上,当用户导航到它时,网页会弹出,执行运行 EXEJS 功能.这样做的目的大概是为了避免用户需要允许EXE运行?我不确定why 和外行的how 一样多。 Default.aspx.vb 包含在 ASPX 文件中,其中不包含任何内容,请参阅以下内容:Partial Class _Default Inherits System.Web.UI.Page End Class
  • var theShell = new ActiveXObject("Shell.Application");此行仅与 ie 不兼容 firefox 或 chrome。
  • 权限在客户端,而不是服务器。就像我说的那样,您的大部分问题都是一个红鲱鱼 - 您不应该尝试使用浏览器运行可执行文件。

【解决方案1】:

我发现我可以通过从后台 C# 代码执行 EXE 来实现这个功能,然后我只需关闭最初创建的网页。

网页:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="EmailSignature_EXEC.aspx.cs" Inherits="_Default" %>

<html>
<head>
    <title></title>
<script>
function loaded()
{
    alert("\\\\cmbfs02\\Software\\web\\EmailSignature_WPF\\EmailSignature_WPF.exe");
    window.setTimeout(CloseMe, 500);
}

function CloseMe() 
{
    window.open('', '_self').close();
}
</script>
<script type="text/javascript">
</script>
</head>
<body onLoad="loaded()">
Hello!
    \\\\cmbfs02\\Software\\web\\EmailSignature_WPF\\EmailSignature_WPF.exe
</body>
</html>

C#代码:

using System.Diagnostics;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load()
    {
        var applicationPath = "\\\\cmbfs02\\Software\\web\\EmailSignature_WPF\\EmailSignature_WPF.exe";
        Process.Start(applicationPath);
        this.ClientScript.RegisterClientScriptBlock(this.GetType(), "Close", "window.close()", true);
    }
}

现在我只需要在部署到服务器时让它工作.....

【讨论】:

  • Process.Start 将始终在服务器上启动进程,而不是在客户端上。您可能会认为它可以像在开发机器上一样工作,客户端 = 服务器。
  • 有趣,我刚刚在这里发布了一个新问题:stackoverflow.com/questions/47397006/… 你认为这是我的问题吗?如果是这样,我还能如何运行 EXE?
