node.js - 将 Visual Studio 调试器附加到 Electron 应用程序

我正在尝试从 Visual Studio 2017(而不是 vscode)从头开始调试 Electron 应用程序。

我创建了一个控制台 nodejs 项目,安装并保存 Electron 。项目结构: enter image description here

app.js的内容(取自electron网站):

'use strict';

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

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

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

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

// Emitted when the window is closed.
win.on('closed', () => {
// 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.
win = 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', () => {
// On macOS 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', () => {
// On macOS 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 (win === null) {
createWindow()
}
})

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

index.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Hello World!</title>
</head>
<body>
<h1>Hello World!</h1>
We are using node
<script>document.write(process.versions.node)</script>,
Chrome
<script>document.write(process.versions.chrome)</script>,
and Electron
<script>document.write(process.versions.electron)</script>.
</body>
</html>

但是,当我单击开始时, Electron 应用程序会启动,但调试过程似乎会自行分离。当我尝试手动将调试器附加到所有 Electron 进程(调试 -> 附加到进程 -> 选择所有 Electron 进程)时,由于没有加载任何符号,因此断点声称不会被命中。 enter image description here

这是项目属性页: enter image description here

我错过了一个步骤吗?既然可以在VSCode上进行调试,那我假设在VS2017上也可以进行调试?

非常感谢。

注意:我确实选中了 Suppress JIT optimization 并取消选中 Enable only my code。

最佳答案

这其实很容易做到。

  1. 像这样在 Visual Studio 中配置您的应用:

enter image description here

  1. 启动您的应用。 Electron 将在一个单独的终端上启动,但 Visual Studio 不会附加到它。

enter image description here

  1. 转到Debug > Attach to process... 并输入Webkit websocket 连接类型和 http://127.0.0.1:5858 作为目标。 enter image description here

  2. 您的断点现已启用。
