我很难理解如何在 .vue 文件中正确导入 ipcRenderer。
我放入 /src/background.js 文件:
webPreferences: {
nodeIntegration:false,
contextIsolation: true, // protects against prototype pollution
preload: path.join(__dirname, "../dist_electron/preload.js"),
}
而且,基于https://nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration我把 preload.js :
window.ipcRenderer = ipcRenderer
webpack.config.js :
module.exports = {
entry: './src/background.js',
target: 'node',
output: {
path: path.join(__dirname, 'build'),
filename: 'background.js'
}
}
为了方便调试,我创建了一个github repo。你可以从这里 git 克隆 repo:https ://github.com/raphael10-collab/ElectronVueTypeScriptScaffolding.git
执行 yarn -> yarn electron:serve 后你会得到正确的页面。
但是在 /src/views/Home.vue 中激活此行时:
//从“电子”导入 { ipcRenderer }
你会得到这个错误:

更新 1)
我尝试将 webPreferences 设置如下(使用 nodeIntegration:true):
webPreferences: {
nodeIntegration: true,
//contextIsolation: true, // protects against prototype pollution
//preload: path.join(__dirname, "../dist_electron/preload.js"),
},
并得到这个错误:
搜索有关此类问题的信息,我发现了这篇文章: 如何解决 fs.existsSync 不是一个函数 通过此链接:https ://webpack.js.org/concepts/targets/
但我已经在 webpack.config.js 中指定了目标“节点”:
在 webpack.config.js 中:
module.exports = {
entry: './src/background.js',
target: 'node',
output: {
path: path.join(__dirname, 'build'),
filename: 'background.js'
}
}
那么......如何解决这个新问题?
顺便说一句,我为什么要放
webPreferences: {
nodeIntegration: true,
}
如果出于安全原因,更安全的是:
webPreferences: {
nodeIntegration:false,
contextIsolation: true, // protects against prototype pollution
preload: path.join(__dirname, "../dist_electron/preload.js"),
}
dist_electron/preload.js :
const {
contextBridge,
ipcRenderer
} = require("electron");
// Expose protected methods that allow the renderer process to use
// the ipcRenderer without exposing the entire object
contextBridge.exposeInMainWorld(
"api", {
send: (channel, data) => {
// whitelist channels
let validChannels = ["toMain"];
if (validChannels.includes(channel)) {
ipcRenderer.send(channel, data);
}
},
receive: (channel, func) => {
let validChannels = ["fromMain"];
if (validChannels.includes(channel)) {
// Deliberately strip event as it includes `sender`
ipcRenderer.on(channel, (event, ...args) =>
func(...args));
}
}
}
);
window.ipcRenderer = ipcRenderer

更新 2)
在 vue.config.js 我放了:
module.exports = {
pluginOptions: {
electronBuilder: {
preload: 'dist_electron/preload.js',
// Or, for multiple preload files:
//preload: { preload: 'src/preload.js', otherPreload:
//'src/preload2.js' }
}
}
}
但是当我这样做时我得到了同样的错误
yarn electron:serve
UncaughtReferenceError: __dirname 未定义
设置 nodeIntegration: true 时(但我更愿意将其设置为 false,并使用 preload.js 文件),我得到另一个错误(如上):
Uncaught TypeError: fs.existsSync is not a function
