从 node.js msg 调用 Windows API [英] Call Windows API from node.js msg

问题描述

我是 Node 的新手，我有这个简单的 Node.js 服务器在 Windows 上运行

I am new at Node, I have this simple Node.js server works on windows

服务器代码

var ws = require("websocket-server");

var server = ws.createServer();

server.addListener("connection", function(client){
    console.log("new connection");
    client.send("aaaaaa");
    client.addListener("message", function(msg){
        console.log(msg);
    });
});

server.listen(8080);

我只想调用 Windows API insted 行

I just want to call windows API insted of line

console.log(msg);

不使用外部库有什么方法可以做到这一点

is there any way to do this without using external library

有什么想法吗?

推荐答案

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.使用 node-ffi，您可以访问 user32(例如)lib 并从 node.js 调用它们的函数.

I think node-ffi can help you to do that. node-ffi provides functionality for loading and calling dynamic libraries. With node-ffi you can get access to user32 (for example) lib and call their functions from node.js.

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
);
