Ndewo, Habr. Nke a bụ edemede nke abụọ na usoro ssh-chat.
Ihe anyị ga-eme:
- Ka anyị tinye ike ịmepụta ọrụ nhazi nke gị
- Ka anyị tinye nkwado markdown
- Ka anyị tinye nkwado bot
- Mụbaa nchekwa okwuntughe (hash na nnu)
Ndo, mana agaghị enwe izipu faịlụ.
Atụmatụ imewe omenala
Ugbu a, a na-akwado ọrụ nhazi ndị a:
@color
@bold
@underline
@hex
@box
Mana ọ bara uru ịgbakwunye ikike ịmepụta ọrụ nke gị:
A na-echekwa ọrụ niile n'imeобъекте под названием methods
Ya mere, ọ ga-ezuru ịmepụta ọrụregisterMethod
:
// parserExec.js at end
module.exports.registerMethod = function(name, func) {
methods[name] = func
}
Ikwesiri iweghachi usoro a mgbe emechara ihe nkesa
// index.js at require part
const { registerMethod } = require('./parserExec')
// index.js at end
module.exports.registerMethod = registerMethod
Ugbu a, mgbe ị na-eke ihe nkesa, anyị nwere ike ịdebanye aha usoro nhazi. Ọmụmaatụ:
const chat = require('.')
const { formatNick } = require('./format')
chat({})
chat.registerMethod('hello', function(p, name){
return 'Hi, ' + formatNick(name) + '!'
})
Nkwado Markdown
Markdown dị ezigbo mma, yabụ ka anyị jiri ya tinye ya
// format.js near require
const marked = require('marked');
const TerminalRenderer = require('marked-terminal');
marked.setOptions({
renderer: new TerminalRenderer()
});
// format.js line 23
message = marked(message)
Bots
Kedu ka ọ ga-esi arụ ọrụ
let writeBotBob = chat.registerBot({
name: 'botBob',
onConnect(nick, write){
write('@hello{' + nick + '}')
},
onDisconnect(nick, write){},
onMessage(nick, message, write) {
if(message == 'botBob!') write('I'm here')
},
onCommand(command, write) {
write('Doing ' + command)
}
})
onCommand
enwere ike ịkpọ iji @bot(botBob){Command}
A kọwara ihe niile maka ịrụ ọrụ na bots na faịlụ:
let bots = []; // Все боты
let onWrite = () => {};
function getWrite(bot) { // Генерирует метод отправки сообщения для бота
return msg => {
onWrite(bot.name, msg);
};
}
module.exports.message = function message(nick, message) { // index.js выполнит эту функцию после отправки сообщения
bots.forEach(bot => {
try {
bot.onMessage(nick, message, getWrite(bot));
} catch (e) {
console.error(e);
}
});
};
module.exports.connect = function message(nick) { // При соединении
bots.forEach(bot => {
try {
bot.onConnect(nick, getWrite(bot));
} catch (e) {
console.error(e);
}
});
};
module.exports.disConnect = function message(nick) { // При отсоединении
bots.forEach(bot => {
try {
bot.onDisconnect(nick, message, getWrite(bot));
} catch (e) {
console.error(e);
}
});
};
module.exports.command = function message(name, message) { // При выполнении команды
bots.forEach(bot => {
if (bot.name == name) {
try {
bot.onCommand(message, getWrite(bot));
} catch (e) {
console.error(e);
}
}
});
};
module.exports.registerBot = function(bot) {
bots.push(bot);
return getWrite(bot)
};
module.exports.onMessage = func => {
onWrite = func;
};
Ihe ị nwere ike ime na bots:
- Nleba anya ibu
- Debe
- bọọdụ ọrụ
Hash na nnu
Gịnị kpatara na ị naghị ssh igodo? N'ihi na igodo ssh ga-adị iche na ngwaọrụ dị iche iche
Ka anyị mepụta faịlụ ga-abụ maka ịlele na ịmepụta okwuntughe
// crypto.js
const crypto = require('crypto');
function genRandomString(length) {
return crypto
.randomBytes(Math.ceil(length / 2))
.toString('hex')
.slice(0, length);
}
function sha512(password, salt){
const hash = crypto.createHmac('sha512', salt); /** Hashing algorithm sha512 */
hash.update(password);
const value = hash.digest('hex');
return value
};
function checkPass(pass, obj){
return obj.password == sha512(pass, obj.salt)
}
function encodePass(pass){
const salt = genRandomString(16)
return JSON.stringify({
salt,
password: sha512(pass, salt)
})
}
module.exports.encodePass = encodePass
module.exports.checkPass = checkPass
Ọzọkwa script maka salting na hashing paswọọdụ
// To generate password run node ./encryptPassword password
const { encodePass } =require('./crypto')
console.log(encodePass(process.argv[2]))
Anyị na-emelite na users.json na kama ịtụnyere na lobby.js anyị na-eji checkPassword
Nsonaazụ
N'ihi ya, anyị nwere mkparịta ụka site na ssh nwere ike imewe na bots.
