[英]Node.js: How to attach to a running process and to debug the server with a console?
[英]How to implement console commands while server is running in Node.js
我正在制作一個游戲服務器,我想在從SSH運行服務器后輸入命令。 例如:addbot,generatemap,kickplayer等。
就像半條命或任何其他游戲服務器一樣。 如何讓Node.js監聽我的命令並仍然使服務器在SSH中運行?
您可以像這樣使用process.stdin :
process.stdin.resume();
process.stdin.setEncoding('utf8');
process.stdin.on('data', function (text) {
console.log(text);
if (text.trim() === 'quit') {
done();
}
});
function done() {
console.log('Now that process.stdin is paused, there is nothing more to do.');
process.exit();
}
否則,你可以使用幫助庫,如提示https://github.com/flatiron/prompt ,它可以讓你這樣做:
var prompt = require('prompt');
// Start the prompt
prompt.start();
// Get two properties from the user: username and email
prompt.get(['username', 'email'], function (err, result) {
// Log the results.
console.log('Command-line input received:');
console.log(' username: ' + result.username);
console.log(' email: ' + result.email);
})
