Sawubona, Habr. Lesi isihloko sesi-2 ochungechungeni lwe-ssh-chat.
Esizokwenza:
- Ake sengeze ikhono lokuzenzela eyakho imisebenzi yedizayini
- Ake sengeze ukwesekwa kokubeka phansi
- Masingeze usekelo lwe-bot
- Khulisa ukuphepha kwephasiwedi (ihashi nosawoti)
Uxolo, kodwa ngeke kube khona ukuthunyelwa kwamafayela.
Izici zokuklama ngokwezifiso
Okwamanje, imisebenzi elandelayo yokuklama iyasekelwa:
@color
@bold
@underline
@hex
@box
Kodwa kufanelekile ukungeza ikhono lokudala imisebenzi yakho:
Yonke imisebenzi igcinwa kuΠΎΠ±ΡΠ΅ΠΊΡΠ΅ ΠΏΠΎΠ΄ Π½Π°Π·Π²Π°Π½ΠΈΠ΅ΠΌ methods
Ngakho-ke kuyoba okwanele ukudala umsebenziregisterMethod
:
// parserExec.js at end
module.exports.registerMethod = function(name, func) {
methods[name] = func
}
Udinga futhi ukubuyisela le ndlela ngemva kokudala iseva
// index.js at require part
const { registerMethod } = require('./parserExec')
// index.js at end
module.exports.registerMethod = registerMethod
Manje, lapho udala iseva, singabhalisa izindlela zokufometha. Isibonelo:
const chat = require('.')
const { formatNick } = require('./format')
chat({})
chat.registerMethod('hello', function(p, name){
return 'Hi, ' + formatNick(name) + '!'
})
Ukusekelwa kwe-Markdown
I-Markdown ilula kakhulu, ngakho-ke masiyengeze 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)
Amabhothi
Izosebenza kanjani
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
kungabizwa ngokuthi usebenzisa @bot(botBob){Command}
Yonke into yokusebenza nama-bots ichazwe efayeleni:
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;
};
Ongakwenza ngama-bots:
- Layisha imonitha
- Sebenzisa
- Ibhodi lomsebenzi
Ihashi nosawoti
Kungani kungabi okhiye be-ssh? Ngoba okhiye be-ssh bazohluka kumadivayisi ahlukene
Masidale ifayela elizoba nesibopho sokuhlola 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
Futhi iskripthi sokwenza usawoti kanye ne-hashing iphasiwedi
// To generate password run node ./encryptPassword password
const { encodePass } =require('./crypto')
console.log(encodePass(process.argv[2]))
Sibuyekeza ku-users.json futhi esikhundleni sokuqhathanisa ku-lobby.js sisebenzisa i-checkPassword
Umphumela
Ngenxa yalokho, sinengxoxo nge-ssh enekhono lokuklama nama-bots.
