Molo, Habr. Eli linqaku le-2 kuthotho lwe-ssh-chat.
Yintoni esiya kuyenza:
- Masidibanise ukukwazi ukwenza imisebenzi yakho yoyilo
- Masiyongeze inkxaso yokumakisha
- Masiyongeze inkxaso ye-bot
- Yandisa ukhuseleko lwephasiwedi (ihashi kunye netyuwa)
Uxolo, kodwa akuyi kubakho kuthunyelwa kweefayile.
Iimpawu zoyilo oluqhelekileyo
Okwangoku, le misebenzi yoyilo ilandelayo iyaxhaswa:
@color
@bold
@underline
@hex
@box
Kodwa kufanelekile ukongeza amandla okwenza imisebenzi yakho:
Yonke imisebenzi igcinwe kuyoΠΎΠ±ΡΠ΅ΠΊΡΠ΅ ΠΏΠΎΠ΄ Π½Π°Π·Π²Π°Π½ΠΈΠ΅ΠΌ methods
Ngoko kuya kukwanela ukudala umsebenziregisterMethod
:
// parserExec.js at end
module.exports.registerMethod = function(name, func) {
methods[name] = func
}
Kwakhona kufuneka ubuyisele le ndlela emva kokudala umncedisi
// index.js at require part
const { registerMethod } = require('./parserExec')
// index.js at end
module.exports.registerMethod = registerMethod
Ngoku, xa udala iseva, sinokubhalisa iindlela zokufomatha. Umzekelo:
const chat = require('.')
const { formatNick } = require('./format')
chat({})
chat.registerMethod('hello', function(p, name){
return 'Hi, ' + formatNick(name) + '!'
})
Inkxaso yeMarkdown
I-Markdown ilunge kakhulu, ngoko masiyongeze sisebenzisa
// 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)
Iibhothi
Izakusebenza njani
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
ingabizwa ngokusetyenziswa @bot(botBob){Command}
Yonke into yokusebenza ne-bots ichazwe kwifayile:
let bots = []; // ΠΡΠ΅ Π±ΠΎΡΡ
let onWrite = () => {};
function getWrite(bot) { // ΠΠ΅Π½Π΅ΡΠΈΡΡΠ΅Ρ ΠΌΠ΅ΡΠΎΠ΄ ΠΎΡΠΏΡΠ°Π²ΠΊΠΈ ΡΠΎΠΎΠ±ΡΠ΅Π½ΠΈΡ Π΄Π»Ρ Π±ΠΎΡΠ°
return msg => {
onWrite(bot.name, msg);
};
}
module.exports.message = function message(nick, message) { // index.js Π²ΡΠΏΠΎΠ»Π½ΠΈΡ ΡΡΡ ΡΡΠ½ΠΊΡΠΈΡ ΠΏΠΎΡΠ»Π΅ ΠΎΡΠΏΡΠ°Π²ΠΊΠΈ ΡΠΎΠΎΠ±ΡΠ΅Π½ΠΈΡ
bots.forEach(bot => {
try {
bot.onMessage(nick, message, getWrite(bot));
} catch (e) {
console.error(e);
}
});
};
module.exports.connect = function message(nick) { // ΠΡΠΈ ΡΠΎΠ΅Π΄ΠΈΠ½Π΅Π½ΠΈΠΈ
bots.forEach(bot => {
try {
bot.onConnect(nick, getWrite(bot));
} catch (e) {
console.error(e);
}
});
};
module.exports.disConnect = function message(nick) { // ΠΡΠΈ ΠΎΡΡΠΎΠ΅Π΄ΠΈΠ½Π΅Π½ΠΈΠΈ
bots.forEach(bot => {
try {
bot.onDisconnect(nick, message, getWrite(bot));
} catch (e) {
console.error(e);
}
});
};
module.exports.command = function message(name, message) { // ΠΡΠΈ Π²ΡΠΏΠΎΠ»Π½Π΅Π½ΠΈΠΈ ΠΊΠΎΠΌΠ°Π½Π΄Ρ
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;
};
Yintoni onokuyenza nge-bots:
- Layisha esweni
- Sebenzisa
- Ibhodi yomsebenzi
Hash kunye netyuwa
Kutheni ingezitshixo ze-ssh? Kuba izitshixo ze-ssh ziya kwahluka kwizixhobo ezahlukeneyo
Masenze ifayile eya kuba noxanduva lokujonga kunye nokudala amagama ayimfihlo
// 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
Kwakhona iskripthi se-salting kunye ne-hashing password
// To generate password run node ./encryptPassword password
const { encodePass } =require('./crypto')
console.log(encodePass(process.argv[2]))
Sihlaziya ku-users.json kwaye endaweni yokuthelekisa kwi-lobby.js sisebenzisa i-checkPassword
Isiphumo
Ngenxa yoko, sinencoko nge-ssh enobuchule bokuyila kunye ne-bots.
