通用网页调用本地应用程序方案(windows平台)

一、更新注册表

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOTreceiveOutOfArg]
"URL Protocol"="D:\LongHaibin\Learn\Net\receiveOutOfArg\receiveOutOfArg\bin\Debug\receiveOutOfArg.exe"
@="applicationName"
[HKEY_CLASSES_ROOTreceiveOutOfArgDefaultIcon]
@="D:\LongHaibin\Learn\Net\receiveOutOfArg\receiveOutOfArg\bin\Debug\receiveOutOfArg.exe,1"
[HKEY_CLASSES_ROOTreceiveOutOfArgshell]
[HKEY_CLASSES_ROOTreceiveOutOfArgshellopen]
[HKEY_CLASSES_ROOTreceiveOutOfArg13:14 2017/5/11shellopencommand]
@=""D:\LongHaibin\Learn\Net\receiveOutOfArg\receiveOutOfArg\bin\Debug\receiveOutOfArg.exe" "%1""

说明：

applicationName:表示网页打开时提示的名称
"%1"：表示要传递的参数，只是%1,"：表示的是转义字符

二、创建一个应用

以下是c#应用程序的代码：入口位置：

static class Program
{
    /// <summary>
    /// 应用程序的主入口点。
    /// </summary>
    [STAThread]
    static void Main(string[] args)
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1(args));
    }
}

窗体代码：

public partial class Form1 : Form
{
    private string[] args;

    public Form1(string[] args)
    {
        this.args = args;
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        this.label1.Text = string.Join(",", this.args);
    }
}

三、创建一个网页

网页用a标签调用即可：

<a href="receiveOutOfArg://abc">open</a>
