Can socket.io-client use https?

Can socket.io-client use https?

connect does not run.

Is option missing?

//設定ファイルの読み込み
require('dotenv').config();

var fs = require('fs');
var ssl_server_key = '../../ssl/new_server.key';
var ssl_server_crt = '../../ssl/server.crt';
var options = {
    key: fs.readFileSync(ssl_server_key),
    cert: fs.readFileSync(ssl_server_crt),
    pfx: fs.readFileSync(ssl_server_crt),
    passphrase: process.env.HTTPS_PASS
};

//socket.io-clientでサーバへ接続
var client = require('socket.io-client');
var socket = client.connect('https://localhost:30000/namespace',options);

//処理
//connectしたら'how are you?'とメッセージを送信する
socket.on('connect',function(){
    console.log('yea!!');
    socket.send('how are you?');
    socket.disconnect();
    process.exit(0);
});

Hi @ikuratakashi !
I have the same prob, how did you solve this?

[ikuratakashi]

//---------------------------------------------

// socket.io-client クラス定義

//---------------------------------------------

naoetu.clsClient = function(){return this.initialize.apply(this,arguments);};

naoetu.clsClient.prototype = {

//引数1 pUrl:接続するURL（例：https://hotge.com:99999/namespace）

initialize : function(pUrl){

    this.url = pUrl;

    this.client = require('socket.io-client');

    this.options = {

        secure:true,

        reconnect: true,

        rejectUnauthorized : false

    };

    this.isConnect = false;

    this.socket = false;

},

//コネクション実行

DoConnect : function(){

    this.socket = this.client.connect(this.url,this.options);

    //接続完了時

    this.socket.on('connect',naoetu.bind(this,function(){

        //thisはsocketの空間になるので注意

        naoetu.log.out(3,'clsClient: connect finish id:' + this.socket.id);

        this.isConnect = true;

    }));

    //接続エラー時

    this.socket.on('connect_error',function(e){

        //thisはsocketの空間になるので注意

        naoetu.log.out(3,'clsClient: connect error :'+ e);

        this.isConnect = false;

    });

    //接続解除時

    this.socket.on('disconnect',function(pRes){

        //thisはsocketの空間になるので注意

        naoetu.log.out(3,'clsClient: disconnect :'+ pRes);

        this.isConnect = false;

    });

}

}

var client = new naoetu.clsClient("https://exmple.com:99999/namespace");
client.DoConnect();
client.socket.emit('message',{msg:"local message"});

This is important.

options = {
secure:true,
reconnect: true,
rejectUnauthorized : false
};

Thank you.

Example added here: https://socket.io/docs/v3/client-initialization/#Node-js-specific-options

Client

const fs = require("fs");
const socket = require("socket.io-client")("https://example.com", {
  ca: fs.readFileSync("./cert.pem")
});

Server

const fs = require("fs");
const server = require("https").createServer({
  cert: fs.readFileSync("./cert.pem"),
  key: fs.readFileSync("./key.pem")
});
const io = require("socket.io")(server);
