问题描述
无法在电子中使用任何电子或节点相关操作.获取错误过程未定义.我检查了他们指导添加节点支持的各个地方，但这已经完成所以卡在这里我的主要应用程序代码是
Unable to use any electron or node related operations in electron . Getting error process not defined. I Checked at various places they guide to add node Support but that is already Done so stucked here My Main Application code is
const electron = require("electron");
const { app, BrowserWindow } = electron;
function createWindow() {
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: { nodeIntegration: true },
});
win.loadFile("index.html");
}
app.whenReady().then(createWindow);
app.on("window-all-closed", () => {
if (process.platform !== "darwin") {
app.quit();
}
});
app.on("activate", () => {
if (BrowserWindow.getAllWindows().length === 0) {
createWindow();
}
});
还有Index.html
And Index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>Hello World!</title>
</head>
<body style="background: white">
<h1>Hello World!</h1>
<p>
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>
.
</p>
</body>
</html>
推荐答案
更新:下面的答案是一种解决方法.您不应禁用 contextIsolation，也不应启用 nodeIntegration.相反，您应该使用 预加载脚本 和 contextBridge API.
Update: the answer below is a workaround. You should not disable contextIsolation and you should not enable nodeIntegration. Instead you should use a preload script and the contextBridge API.
在 Electron 12 中，contextIsolation 现在默认为 true
In Electron 12, contextIsolation is now by default true
如果您将其设置为 false，您将可以在渲染器进程中访问 Node.js API
If you set it to false, you will have access to Node.js APIs in the renderer process
function createWindow() {
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
contextIsolation: false,
nodeIntegration: true
},
});
win.loadFile("index.html");
}
需要注意的是，不推荐这样做！
Electron 维护者更改默认值是有充分理由的.请参阅此讨论
There's a good reason why Electron maintainers changed the default value. See this discussion
如果没有 contextIsolation，渲染器进程中运行的任何代码都可以很容易地进入 Electron 内部或您的预加载脚本，并执行您不希望任意网站执行的特权操作.
Without contextIsolation any code running in a renderer process can quite easily reach into Electron internals or your preload script and perform privileged actions that you don't want arbitrary websites to be doing.
