ElectronJS，JavaScript和Python-未定义require尝试了所有选项 [英] ElectronJS, JavaScript and Python - require is not defined tried all the options
问题描述
尝试执行以下行时出现问题：
I have a problem when I try to execute the following line:
var path = require('path')
我得到
Uncaught ReferenceError: require is not defined
除了require错误外，其他所有方法都可以正常工作，为什么？
all work fine except from require error, why?
我有3个文件：
translate.js：
translate.js:
function get_translate(){
var path = require('path')
var trans = document.getElementById("trans").value
document.getElementById("trans").value = ""
var options = {
scriptPath : path.join(__dirname, '/../engine/'),
args : [trans]
}
translate = PythonShell.run('translate_engine.py', options);
translate.on('message', function(message) {
swal(message);
})
}
translate.html：
translate.html:
<head>
<link rel="stylesheet"
href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">
</script>
<script src="linkers/translate.js"></script>
</head>
<body>
<br>
<div class="container">
<button="btn btn-info"><a style="color:white" href="gui.html">Back</a>
</button>
<div class="jumbotron">
<h1>Translate App</h1>
<br>
<label>Enter you word here</label>
<input id="trans" type="text" placeholder="Text"/>
<button class="but but-success" onclick="get_translate()">Go</button>
</div>
</body>
translate_engine.py：
translate_engine.py:
import sys
trans = sys.argv[1]
print(trans)
sys.stdout.flush()
谢谢
推荐答案
您是否要执行
如果是，请检查 nodeIntegration 是否未设置为<$ c $初始化 BrowserWindow 时c> false 。
If yes, check if nodeIntegration isn't set to false when initiating the BrowserWindow.
mainWindow = new BrowserWindow({
minWidth: 370,
minHeight: 520,
webPreferences: {
nodeIntegration: true,
},
});
nodeIntegration 实际上是 true 默认情况下，因此您也可以删除此行–我只是想使其非常明显；）
nodeIntegration is actually true by default, so you can remove this line as well – I'm just trying to make it super obvious ;)
由于 nodeIntegration 是 true ，因此您可以在电子渲染过程中运行任何 nodeJS代码。
As long as nodeIntegration is true you can run any nodeJS code in the electron render process.
这超出了您最初的问题，并且更加高级，但是如果您不想启用它，因为它附带了许多安全问题，您可以将某些nodeJS方法暴露给渲染过程。您可以使用预加载脚本来做到这一点。
This goes beyond your initial question and it's a little bit more advanced, but If you don't want to enable this as it comes with numerous security issues, you can just expose certain nodeJS methods to the render process. You can do this with a preload script.
mainWindow = new BrowserWindow({
...
webPreferences: {
nodeIntegration: false,
preload: path.join(__dirname, 'preload.js') // here you can re-expose certain methods such as `require`
},
});
preload字符串（可选）-指定将在之前加载的脚本其他脚本在页面中运行。无论打开还是关闭节点集成，此脚本始终可以访问节点API。该值应该是脚本的绝对文件路径。关闭节点集成后，预加载脚本可以将节点全局符号重新引入全局范围。
preload String (optional) - Specifies a script that will be loaded before other scripts run in the page. This script will always have access to node APIs no matter whether node integration is turned on or off. The value should be the absolute file path to the script. When node integration is turned off, the preload script can reintroduce Node global symbols back to the global scope.
