将 visual studio 调试器附加到电子应用程序

Attach visual studio debugger to electron app

我正在尝试从头开始调试 visual studio 2017 年(而不是 vscode)的电子应用程序。

我创建了一个控制台nodejs项目,安装并保存electron。项目结构:

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,当我点击开始时,电子应用程序启动了,但调试过程似乎脱离了自己。当我尝试手动将调试器附加到所有电子进程(调试 -> 附加到进程 -> 选择所有电子进程)时,断点声称不会被击中,因为没有加载任何符号。

这是项目 属性 页面:

有没有我漏掉的步骤?由于调试可以在 VSCode 上完成,我想它也可以在 VS2017 上完成?

非常感谢。

注意:我确实选中了抑制 JIT 优化并取消选中仅启用我的代码。

在您的 "Node.exe Options" 字段中,为 NodeJS v6 及以下版本添加 --debug=$DEBUG_PORT 或为 NodeJS v7 或更高版本添加 --inspect=$DEBUG_PORT 其中 $DEBUG_PORT 表示您拥有的端口在您的调试配置中指定。

如果你不传递端口而只传递 --debug--inspect 标志,那么 Node 调试器将分别侦听端口 5858 和 9229...他们将默认端口更改为 9229在更高版本的节点中。

如果有帮助请告诉我!


For seeing why symbols are not loading type the following commands in .

Creating an Electron app using Visual Studio (not VSCode) w/ Node.js tools

这其实很容易做到。

  1. 像这样在 Visual Studio 中配置您的应用程序:

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

  1. 转到调试>附加到进程...并输入Webkit websocket连接类型和http://127.0.0.1:5858 作为目标。

  2. 您的断点现已启用。
