Electronを使用してデフォルトのブラウザでリンクを開く方法

debugcn 投稿 Dev

ジョエル

私は次のような単純なbrowserWindowを使用しています：

let win = new BrowserWindow({
  width: 500, 
  height: 613, 
  title: 'My App',
  autoHideMenuBar:true,
  icon: path.join(__dirname, 'logo.ico'),
  resizable:false,
  backgroundColor:"#2c2f33",
  webPreferences: {
    session : session,
    webSecurity: false,
  }
})
win.on('closed', () => {
  win = null
})

// Load a remote URL
win.loadURL('http://192.168.40.189:1337')
session.fromPartition('persist:name');
session.defaultSession.cookies.get({}, (error, cookies) => {
  console.log(error, cookies)
})

ブラウザウィンドウ内のリンクをクリックするたびに、電子ブラウザウィンドウの新しいインスタンスが作成されます。デフォルトのシステムブラウザでリンクを開くことは可能ですか？（chrome / firefox / vivaldi / etc）

私はとりわけこれらのリソースを読みました。しかし、成功したものはありません。

Electronブラウザ-ウィンドウドキュメント

デフォルトのOSブラウザからURLを開くにはどうすればよいですか？

編集：

私はこれを試しました、そしてそれは私が見つけたすべての解決策の中で最もうまくいく可能性が高いようです、しかしそれは私に与えます：webContents.on is not a function。

const {webContents} = require('electron')

var handleRedirect = (e, url) => {
  if(url != webContents.getURL()) {
    e.preventDefault()
    require('electron').shell.openExternal(url)
  }
}

webContents.on('will-navigate', handleRedirect)
webContents.on('new-window', handleRedirect)

これはwebContents、静的関数の代わりにのクラスインスタンスメソッドを使用して試した方法で実行できます。

const { app, BrowserWindow, shell } = require('electron')

app.once('ready', () => {
  const handleRedirect = (e, url) => {
    if (url !== e.sender.getURL()) {
      e.preventDefault()
      shell.openExternal(url)
    }
  }
  const win = new BrowserWindow()
  // Instead bare webContents:
  win.webContents.on('will-navigate', handleRedirect)
  win.loadURL('http://google.com')
})
