Recommended Posts

Testing new login system with api (at this time old login system works fine)
Attached 2 methods from bot class. I think general problem arises on PollAuthSessionStatus.
I never got access_token prop with i think JWT for https://login.steampowered.com/jwt/finalizelogin
Maybe someone know what i made wrong
Some info in code comments

async sendRequest(url, body = {}, method = 'GET', headers = {}, fetchOptions = {}){
        let createSteamQueryStringBody = (body) => {
            if(Object.keys(body).length == 0)
                return ``

            let newBody = ``
            for(let key in body){
                if(typeof body[key] == 'object')
                    body[key] = JSON.stringify(body[key])
                    
                newBody += `${key}=${encodeURIComponent(body[key])}&`
            }

            return `?${newBody}`.slice(1, -1)
        }

        let requestOptions = {
            headers: {
                'content-type': 'application/x-www-form-urlencoded; charset=UTF-8'

        }

        if(this.proxy && this.proxy.includes('http')){
            requestOptions['agent'] = new httpsProxyAgent(this.proxy)
        }

        if(method != 'GET')
            requestOptions.body = createSteamQueryStringBody(body)

        requestOptions.method = method
        requestOptions.headers = Object.assign(requestOptions.headers, headers)

        requestOptions = {...requestOptions, ...fetchOptions}
        
        let response = await fetch(url, requestOptions)
