问题描述
每个人晚上，
我已经开始为我想使用电子框架编写的应用程序做一些研究。我已经弄清楚了如何向用户显示我想要的内容，除了图标。在应用程序的一部分中，用户可以键入路径，它将在该路径中列出文件，我想从文件中拉出图标，以便图标显示出来，就像在Windows文件浏览器中一样。这是我遇到障碍的地方，我正在寻找一些指导。
I have started doing some research for an application i want to write using the electron framework. I have figured out how to display what i want to the user with the exception of the icons. There is a part of the application where the user can type a path and it will list the files in that path, i would like to pull the icon from the files so its displayed just like it would be in the windows file explorer. This is where i have been running into a roadblock and I'm looking for some guidance.
nodejs中是否有一种方法可以让我提供文件路径并作为回报，我可以传递给HTML图片吗？我是nodejs的新手，所以我想我会问问是否有人知道一种简单的方法。
Is there a method in nodejs that would allow me to provide a file path and in return get a image back i can pass to HTML? Im new to nodejs so i figured i would ask and see if anyone knew of an easy way.

有
，您可以像这样使用它从系统中提取任何应用程序图标，但它必须是** .. exe * *文件。
There is icon-extractoryou can use it like this to extract any app icon from the system , but it must be an**".exe"** file.
var iconExtractor = require（'icon-extractor'）;
var fs = require（'fs'）;
iconExtractor.emitter.on('icon', function(data){
console.log('Here is my context: ' + data.Context);
console.log('Here is the path it was for: ' + data.Path);
var icon = data.Base64ImageData;
fs.writeFile('img.png', icon, 'base64', (err) => {
console.log(err);
});
});
iconExtractor.getIcon('ANY_TEXT','PAHT_TO_APP.exe');
