Node.js JavaScript: Simulate Keypress on Server (Like a Macro)
提问by Nimaid
I am trying to get a node.js script to simulate a keypress, such as the up arrow or the a button. Specifically, I am trying to make a clone of Twitch Plays Pokemon. Basically, whenever a command (up, down, left, right, a, b, select, start) is sent via IRC, the server simulates a keypress, which in turn controls a gameboy emulator. So far, I have written this with the IRC module for node.js:
我正在尝试使用 node.js 脚本来模拟按键，例如向上箭头或 a 按钮。具体来说，我正在尝试制作Twitch Plays Pokemon的克隆。基本上，每当通过 IRC 发送命令（向上、向下、向左、向右、a、b、选择、开始）时，服务器都会模拟按键，进而控制游戏机模拟器。到目前为止，我已经用 node.js 的 IRC 模块编写了这个：
var config = {
channels: ["#tron"],
server: "irc.freenode.net",
botName: "wyatt"
};
var irc = require("irc");
var bot = new irc.Client(config.server, config.botName, {
channels: config.channels
});
var commandHandler = function(from, text) {
if(text.toLowerCase() === "up"||text.toLowerCase() === "down"||text.toLowerCase() === "left"||text.toLowerCase() === "right"||text.toLowerCase() === "a"||text.toLowerCase() === "b"||text.toLowerCase() === "select"||text.toLowerCase() === "start") {
bot.say(config.channels[0], from.toUpperCase() + " sent the " + text.toUpperCase() + " command!");
} else {
bot.say(config.channels[0], from.toUpperCase() + ", that wasn't a valid command!");
}
};
bot.addListener("message", function(from, to, text, message) {
commandHandler(from, text);
});
To run my script, I type node scriptName.js into a command prompt. I am using Windows 7.
为了运行我的脚本，我在命令提示符中键入 node scriptName.js。我正在使用 Windows 7。
This connects to the freenodechannel #tron, which I am using for testing purposes, as it seems to be mainly dormant.
这连接到freenode频道#tron，我将其用于测试目的，因为它似乎主要处于休眠状态。
When a user inputs one of the accpted commands, it sends a message like "NIMAID sent the LEFT command!", otherwise it sends "NIMAID, that wasn't a valid command!". As it is, it works flawlessly. So all I need to do is find a way to send a keypress and the final script is just a switch statement away.
当用户输入其中一个已接受的命令时，它会发送一条消息，例如“NIMAID 发送了 LEFT 命令！”，否则它会发送“NIMAID，那不是有效命令！”。事实上，它完美无缺。所以我需要做的就是找到一种发送按键的方法，而最终的脚本只是一个 switch 语句。
The trouble is that any references I can find by searching the internet talks about using node.js in a browser environment, with JQuery or something similar. I need to send keypresses to an emulator.
问题是，我可以通过在互联网上搜索有关在浏览器环境中使用 node.js，使用 JQuery 或类似的东西找到的任何参考资料。我需要将按键发送到模拟器。
tldr: I need to send keypresses from a node.js script to an application running on the windows 7 server desktop.
tldr：我需要将按键从 node.js 脚本发送到在 Windows 7 服务器桌面上运行的应用程序。
Is there any way to do this?
有没有办法做到这一点？

I made a node module to do this too: https://github.com/kylepaulsen/kbm-robot
我也做了一个节点模块来做到这一点：https: //github.com/kylepaulsen/kbm-robot
var robot = require("kbm-robot");
robot.startJar();
robot.press("alt")
.press("tab")
.sleep(100)
.release("tab")
.release("alt")
.sleep(100)
.typeString("Hello World!")
.go()
.then(robot.stopJar);

Apparently, there's a win_keyboardmodule in the npm registry that somebody wrote to control the keyboard in Windows. You can run npm install win_keyboardand use that; it appears to do exactly what you want.
显然，有人编写的 npm 注册表中有一个win_keyboard模块来控制 Windows 中的键盘。你可以运行npm install win_keyboard并使用它；它似乎完全符合您的要求。

You may try an alternative to RobotJS. It is a very small and still cross platform library to send keys to your operational system called node-key-sender. I developed after getting frustrated with RobotJS and kbm-robot.
您可以尝试使用 RobotJS 的替代方法。它是一个非常小且仍然跨平台的库，用于将密钥发送到名为 node-key-sender 的操作系统。在对 RobotJS 和 kbm-robot 感到沮丧后，我开发了它。
Install it with npm install --save-dev node-key-sender.
安装它npm install --save-dev node-key-sender。
And send a text to the keyboard using:
并使用以下命令向键盘发送文本：
var ks = require('node-key-sender');
ks.sendText('This is my text');
Check out the documentation page: https://www.npmjs.com/package/node-key-sender.
