将visual studio调试器附加到电子应用程序

我正试图从头开始从Visual Studio 2017(而不是vscode)调试电子应用程序。

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

app.js的内容(取自电子网站):

'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>

然而,当我点击开始时,电子应用程序启动,但调试过程似乎自行分离。当我尝试手动将调试器连接到所有电子过程(Debug - &gt; Attach to process - &gt;选择所有电子过程)时,断点声称不会被命中,因为没有加载符号。 enter image description here

这是项目属性页面: enter image description here

我错过了一步吗?由于可以在VSCode上进行调试,我认为它也可以在VS2017中完成?

非常感谢。

注意:我确实检查了抑制JIT优化并取消选中仅启用我的代码。

这实际上很容易做到。

  1. 在Visual Studio中配置您的应用程序,如下所示:
  2. 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不会附加到它上面。
    2. enter image description here

      1. 转到调试&gt;附加到流程... 并输入 Webkit websocket 连接类型,并输入 http://127.0.0.1:5858 作为目标。 enter image description here

      2. 您的断点现已启用。

      3. enter image description here

在“Node.exe选项”字段中,为NodeJS v6及更低版本添加--debug=$DEBUG_PORT或为NodeJS v7或更高版本添加--inspect=$DEBUG_PORT,其中$DEBUG_PORT用于表示您指定的端口在你的调试配置中。

如果您没有传递端口并且只传递--debug--inspect标志,则Node调试器分别侦听端口5858和9229 ......他们稍后将默认端口更改为9229节点的版本。

请告诉我这是否有帮助!

要查看未加载符号的原因,请在Windbg中输入以下命令。

> !sym noisy
> .reload /f electron.exe
