How to launch an application from a browser?
提问by Goro
Is it possible to launch an application from a browser? I am not talking about opening a file from a browser (like open a PDF with Adobe Reader), but rather opening a new (blank) instance of an application that is installed on the user's machine.
是否可以从浏览器启动应用程序？我不是在谈论从浏览器打开文件（如使用 Adobe Reader 打开 PDF），而是打开安装在用户机器上的应用程序的新（空白）实例。
Hypothetical situation: User browses a website that lists computers that can be managed via RDP. He clicks on a link to 192.168.1.10, that link opens Microsoft RDP client (mstsc.exe) with that ip address already filled out.
假设情况：用户浏览的网站列出了可以通过 RDP 管理的计算机。他单击指向 192.168.1.10 的链接，该链接会打开 Microsoft RDP 客户端 (mstsc.exe)，其中已填写该 IP 地址。
I am talking strictly about Windows universe.
我严格地谈论 Windows 宇宙。
Is that thing even doable outside of ActiveX and IE?
在 ActiveX 和 IE 之外，这件事甚至可行吗？
Is it wise to attempt this in IE with ActiveX?
使用 ActiveX 在 IE 中尝试这样做是否明智？

You can't really "launch an application" in the true sense. You can as you indicated ask the user to open a document (ie a PDF) and windows will attempt to use the default app for that file type. Many applications have a way to do this.
您无法真正“启动应用程序”。您可以按照您的指示要求用户打开文档（即 PDF），Windows 将尝试使用该文件类型的默认应用程序。许多应用程序有办法做到这一点。
For example you can save RDP connections as a .rdp file. Putting a link on your site to something like this should allow the user to launch right into an RDP session:
例如，您可以将 RDP 连接保存为 .rdp 文件。在您的网站上放置一个指向类似内容的链接应该允许用户直接启动 RDP 会话：
<a href="MyServer1.rdp">Server 1</a>

Some applications launches themselves by protocols. like itunes with "itms://" links. I don't know however how you can register that with windows.
一些应用程序通过协议自行启动。像带有“itms://”链接的 iTunes。但是，我不知道如何在 Windows 中注册它。

We use a sonicwall vpn. It launches a java applet that launches mstc with all the credentials setup. You really can't do this without a java applet or activex plugin.
我们使用 sonicwall vpn。它启动一个 java 小程序，该小程序启动带有所有凭据设置的 mstc。如果没有 java 小程序或 activex 插件，您真的无法做到这一点。
Microsoft uses this technique itself on their small business server for getting inside the network. I wouldn't say it is a terrible idea, as long as platform independence isn't important.
微软在他们的小型企业服务器上使用这种技术来进入网络。我不会说这是一个糟糕的主意，只要平台独立性不重要。

The correct method is to register your custom URL Protocol in windows registry as follows:
正确的方法是在 windows 注册表中注册您的自定义 URL 协议，如下所示：
[HKEY_CLASSES_ROOT\customurl]
@="Description here"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\customurl\shell]
[HKEY_CLASSES_ROOT\customurl\shell\open]
[HKEY_CLASSES_ROOT\customurl\shell\open\command]
@="\"C:\Path To Your EXE\ExeName.exe\" \"%1\""
Once the above keys and values are added, from the web page, just call "customurl:\\parameter1=xxx¶meter2=xxx" . You will receive the entire url as the argument in exe, which you need to process inside your exe. Change 'customurl' with the text of your choice.
添加上述键和值后，从网页中，只需调用 "customurl:\\parameter1=xxx¶meter2=xxx" 。您将收到整个 url 作为 exe 中的参数，您需要在 exe 中对其进行处理。使用您选择的文本更改“customurl”。

I achieved the same thing using a local web server and PHP. I used a script containing shell_execto launch an application locally.
我使用本地 Web 服务器和 PHP 实现了同样的目标。我使用了一个包含shell_exec在本地启动应用程序的脚本。
Alternatively, you could do something like this:
或者，您可以执行以下操作：
<a href="file://C:/Windows/notepad.exe">Notepad</a>
回答by JoBaxter
You can use the following:
您可以使用以下内容：
<a href="c:\windows\Notepad.exe"
type="application/octet-stream">Launch Notepad</a>
From what I remember using file:// is blocked by Chrome and Firefox.
我记得使用 file:// 被 Chrome 和 Firefox 阻止。
