The right socket.io version cloent to use

[Notadumdum]

Hey Miguel I heard python doesnt work well with browser based client and that i must use javascript
I just have one question.. please what version of socket.io should i use and must it tally with the exact version the server uses... note that the URL has EIO=3 in it...and when i ran code multiple times and checked the reason it showed transport close... i did not even get any sid back to begin with.. the disconnect event was what was always called.. any advice?

[bhakta0007]

please follow this version guide and it will just work fine:

https://python-socketio.readthedocs.io/en/latest/intro.html#version-compatibility

this is what I am using:

JS:

grep -i socket package.json
    "socket.io-client": "^4.5.1",

Python:

➜ grep -i socket requirements.txt
Flask-SocketIO==5.1.2
python-socketio==5.6.0
socketIO-client==0.7.2
websocket-client==0.57.0

const socket = require('socket.io-client')('https://ws2.qxbroker.com/socket.io/')

socket.on('connect',() => {
    console.log('connected to the server')

})

socket.on('event',(data) => {
    socket.emit("authorization",JSON.stringify({"session":"rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrtrrr","isDemo":1}))
    socket.emit("tick")
    socket.emit("indicator/list")
    socket.emit("drawing/load")
    socket.emit("pending/list")
    socket.emit("instruments/update",JSON.stringify({"asset":"NZDUSD","period":60}))
    socket.emit("chart_notification/get")
    socket.emit("depth/follow","NZDUSD")
    socket.emit("settings/store",JSON.stringify({"chartId":"graph","settings":{"chartId":"graph","chartType":2,"currentExpirationTime":0,"isFastOption":false,"isFastAmountOption":false,"isIndicatorsMinimized":false,"isIndicatorsShowing":true,"isShortBetElement":false,"chartPeriod":4,"currentAsset":{"symbol":"NZDUSD"},"dealValue":1000,"dealPercentValue":1,"isVisible":true,"timePeriod":60,"gridOpacity":8,"isAutoScrolling":1,"isOneClickTrade":true,"upColor":"#0FAF59","downColor":"#FF6251"}}))
    console.log('event:' + data)
})

socket.on('disconnect',() => {
    console.log('disconnected from server')
})

@bhakta0007 this is the code i used earlier

What kind of socket io server is the qxbroker running? When i tried a sample program to connect to the server, I See

how does one authenticate with the server? I see from your code above that you are sending authorization on an event. How is this supposed to work? Can you elaborate a bit on what the server is and how it expects users to connect and authorize?

I would have though that you would be sending some headers containing authorization during connect itself.

Its amazing that you could get an sid{} sent back to you.. this code went straight to disconnect for me...i dont really know how the server is meant to authenticate.. i'm basically trying to replicate the connection using what i could see in "qxbroker.com" devtools..also please did you change anything in the code and what version of socket.io is this @bhakta0007

[Notadumdum]

Also would this stylesheet help in any way @bhakta0007
Please can I have your email

[Notadumdum]

If it helps in anyway the server used is nginx @bhakta0007
