我在 index.js 中做了以下操作；

electron.remote.app.on("open-url", function(event, url) {
  console.log("Open URL: " + url);
});

这会在 Mac OS 中触发，但不会在 Windows 中触发。在 Windows 中是否有其他事件或不同的方式来执行它？

最佳答案

From mine similar Q/A at SO : 这是关于使用 Electron 为两个平台(macOS/win32)打开应用程序并通过深度链接传递参数。

Minimal electron project with deep linking capabilities in macOS/win32 platforms (Single Instance Application) 'electron-deep-linking-mac-win' on GitHub.

main.js:

const {app, BrowserWindow} = require('electron')
// Module with utilities for working with file and directory paths.
const path = require('path')
// Module with utilities for URL resolution and parsing.
const url = require('url')

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow

// Deep linked url
let deeplinkingUrl

// Force Single Instance Application
const shouldQuit = app.makeSingleInstance((argv, workingDirectory) => {
  // Someone tried to run a second instance, we should focus our window.

  // Protocol handler for win32
  // argv: An array of the second instance’s (command line / deep linked) arguments
  if (process.platform == 'win32') {
    // Keep only command line / deep linked arguments
    deeplinkingUrl = argv.slice(1)
  }
  logEverywhere("app.makeSingleInstance# " + deeplinkingUrl)

  if (mainWindow) {
    if (mainWindow.isMinimized()) mainWindow.restore()
        mainWindow.focus()
  }
})
if (shouldQuit) {
    app.quit()
    return
}

function createWindow () {
  // Create the browser window.
  mainWindow = new BrowserWindow({width: 800, height: 600})

  // and load the index.html of the app.
  mainWindow.loadURL(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))

  // Open the DevTools.
  mainWindow.webContents.openDevTools()

  // Protocol handler for win32
  if (process.platform == 'win32') {
    // Keep only command line / deep linked arguments
    deeplinkingUrl = process.argv.slice(1)
  }
  logEverywhere("createWindow# " + deeplinkingUrl)

  // Emitted when the window is closed.
  mainWindow.on('closed', function () {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null
  })
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)

// Quit when all windows are closed.
app.on('window-all-closed', function () {
  // On OS X it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', function () {
  // On OS X it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (mainWindow === null) {
    createWindow()
  }
})

// Define custom protocol handler. Deep linking works on packaged versions of the application!
app.setAsDefaultProtocolClient('myapp')

// Protocol handler for osx
app.on('open-url', function (event, url) {
  event.preventDefault()
  deeplinkingUrl = url
  logEverywhere("open-url# " + deeplinkingUrl)
})

// Log both at dev console and at running node console instance
function logEverywhere(s) {
    console.log(s)
    if (mainWindow && mainWindow.webContents) {
        mainWindow.webContents.executeJavaScript(`console.log("${s}")`)
    }
}

main.js 代码说明:

• 在 let deeplinkingUrl 我们保留提供的 url。

• 在 macOS 平台上，这是在 'open-url' event 上捕获的。 ，我们用 deeplinkingUrl = url 设置它! (参见 //osx 的协议(protocol)处理程序)

• 在 win32 平台上保存在 process.argv连同其他论点。要仅获取提供的 url，deeplinkingUrl = argv.slice(1)。 (参见 //win32 的协议(protocol)处理程序)

• 作为 @Aurélien Nicolas提到，在 app.makeSingleInstance method我们检查我们所在的平台，并相应地设置 deeplinkingUrl!如果我们在 win32 平台，url 位于回调的 argv 变量中，否则在 macOS 应该已经在 'open-url' 事件中设置! (见//强制单实例应用)

关于node.js - Electron url 方案 "open-url"事件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38458857/
