var server = ws.createServer();
server.addListener("connection", function(client){

I think node-ffican help you to do that. node-ffiprovides functionality for loading and calling dynamic libraries. With node-ffiyou can get access to user32(for example) lib and call their functions from node.js.
我认为node-ffi可以帮助您做到这一点。node-ffi提供加载和调用动态库的功能。有了它，node-ffi您就可以访问user32（例如）lib 并从 node.js 调用它们的函数。
var FFI = require('node-ffi');
function TEXT(text){
return new Buffer(text, 'ucs2').toString('binary');
}
var user32 = new FFI.Library('user32', {
'MessageBoxW': [
'int32', [ 'int32', 'string', 'string', 'int32' ]
]
});
var OK_or_Cancel = user32.MessageBoxW(
0, TEXT('I am Node.JS!'), TEXT('Hello, World!'), 1
);

I didn't want to edit @Vadim's answer because it is accepted, but I think the package has been renamed to just 'ffi'. This worked for me:
我不想编辑@Vadim 的答案，因为它已被接受，但我认为该软件包已重命名为“ ffi”。这对我有用：
npm install -s ffi
And using @Vadim's source but changing the package name to ffi:
并使用@Vadim 的源代码但将包名称更改为ffi：
var FFI = require('ffi');
function TEXT(text){
return new Buffer(text, 'ucs2').toString('binary');
}
var user32 = new FFI.Library('user32', {
'MessageBoxW': [
'int32', [ 'int32', 'string', 'string', 'int32' ]
]
});
var OK_or_Cancel = user32.MessageBoxW(
0, TEXT('I am Node.JS!'), TEXT('Hello, World!'), 1
);

You can also use this NPM package which already has (much of) the Win32 API entered (using ffi) and ready to use from NodeJS: https://github.com/waitingsong/node-win32-api
您还可以使用这个 NPM 包，它已经输入了（大部分）Win32 API（使用 ffi）并准备从 NodeJS 使用：https: //github.com/waitingsong/node-win32-api
