Protocol steammobile not supported or disabled in libcurl

[saqwel]

I know Trade offers works fine with PHP 5.6 from another server (with another configuration). But I have PHP 7.0.3. I configure it and install. Authentication work fine. But when I trying to execute
$tradeId = $trade->sendWithToken( $some_token );
$tradeId is return as 0.
To SteamCommunity.php in
public function cURL($url, $ref = null, $postData = null)
was added
echo curl_error($ch);
Result: Protocol steammobile not supported or disabled in libcurl.
How does enable steammobile protocol or make protocol redirect?

Show me your entire code, none of the above stuff has "steammobile" in the URL.

[saqwel]

I don't find "steammobile" too. But can't find what that error mean.
My code:
I had rewrite your example:

require '/web/composer/vendor/autoload.php';

use waylaidwanderer\SteamCommunity\Enum\LoginResult;
use waylaidwanderer\SteamCommunity\MobileAuth\WgTokenInvalidException;
use waylaidwanderer\SteamCommunity\SteamCommunity;

$settings   = json_decode(file_get_contents($_SERVER['DOCUMENT_ROOT'] . '/_steam/settings.json'), true);
$steam      = new SteamCommunity($settings, $_SERVER['DOCUMENT_ROOT'] . '/_steam' );

$steam->setTwoFactorCode($steam->mobileAuth()->steamGuard()->generateSteamGuardCode());
$loginResult = $steam->doLogin();

while ($loginResult != LoginResult::LoginOkay) {
    if ($loginResult == LoginResult::Need2FA) {
        if ($steam->mobileAuth()->steamGuard() == null) {
            //$authCode = 'Enter 2FA code: ';
            //$steam->setTwoFactorCode($authCode);
        } else {
            $authCode = $steam->mobileAuth()->steamGuard()->generateSteamGuardCode();
            $steam->setTwoFactorCode($authCode);
            //echo 'Generated Steam Guard code: ' . $authCode . '<br>';
            $loginResult = $steam->doLogin();
        }
    } else if ($loginResult == LoginResult::NeedEmail) {
        $authCode = 'Enter Steam Guard code from email: ';
        $steam->setEmailCode($authCode);
        $loginResult = $steam->doLogin();
    } else if ($loginResult == LoginResult::NeedCaptcha) {
        $captchaCode = 'Enter captcha (' . $steam->getCaptchaLink() . '): ';
        $steam->setCaptchaText($captchaCode);
        $loginResult = $steam->doLogin();
    } else {
        break;
    }
    echo "Login result: ".$loginResult."<br>";
}

if ($loginResult == LoginResult::LoginOkay) {
    $tradeOffers = $steam->tradeOffers();
    //var_dump($tradeOffers->getTradeOffersViaAPI(true));

    $trade = $tradeOffers->createTrade('307769701');
    $trade->addOtherItem(730, 2, '4813427756');
    $tradeId = $trade->sendWithToken('307769701');
    //$tradeId = $trade->send();
    var_dump($tradeId).'<br>';

    try {
        $confirmations = $steam->mobileAuth()->confirmations()->fetchConfirmations();
        foreach ($confirmations as $confirmation) {
            $tradeIdConfirm = $steam->mobileAuth()->confirmations()->getConfirmationTradeOfferId($confirmation);
            echo $tradeIdConfirm.'<br>';
            if( $tradeId==$tradeIdConfirm ) {
                var_dump($steam->mobileAuth()->confirmations()->acceptConfirmation($confirmation));
            }
        }
    } catch (WgTokenInvalidException $ex) {
        // session invalid
        $steam->mobileAuth()->refreshMobileSession();
    }
}

Add one string to your function echo curl_error($ch); for troubleshooting:

public function cURL($url, $ref = null, $postData = null)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
        if (!empty($this->rootDir)) {
            curl_setopt($ch, CURLOPT_COOKIEFILE, $this->_getCookieFilePath());
            curl_setopt($ch, CURLOPT_COOKIEJAR, $this->_getCookieFilePath());
        }
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
        if ($this->mobile) {
            curl_setopt($ch, CURLOPT_HTTPHEADER, ["X-Requested-With: com.valvesoftware.android.steam.community"]);
            curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Linux; U; Android 4.1.1; en-us; Google Nexus 4 - 4.1.1 - API 16 - 768x1280 Build/JRO03S) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30");
            curl_setopt($ch, CURLOPT_COOKIE, $this->buildCookie(self::$DEFAULT_MOBILE_COOKIES));
        } else {
            curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.3; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0');
        }
        if (isset($ref)) {
            curl_setopt($ch, CURLOPT_REFERER, $ref);
        }
        if (isset($postData)) {
            curl_setopt($ch, CURLOPT_POST, true);
            $postStr = "";
            foreach ($postData as $key => $value) {
                if ($postStr)
                    $postStr .= "&";
                $postStr .= $key . "=" . $value;
            }
            curl_setopt($ch, CURLOPT_POSTFIELDS, $postStr);
        }
        curl_setopt($ch, CURLOPT_PROTOCOLS, CURLPROTO_ALL);
        $output = curl_exec($ch);
        echo curl_error($ch);
        curl_close($ch);
        return $output;
    }

One thing I noticed is that your trade token is incorrect. $tradeId = $trade->sendWithToken('307769701'); This is the accountId, not the tradeToken.

[saqwel]

You can check "accountid_other" in this trade offer:
http://api.steampowered.com/IEconService/GetTradeOffer/v1/?tradeofferid=1034071107&language=english&key=<enter your api key here>
This code works correctly from another server. Your code work well, my data is correct. But I think I have wrong configuration of PHP. Main question: What does mean Protocol steammobile not supported or disabled in libcurl?

[saqwel]

Ohh! I understand what you mean when say "This is the accountId, not the tradeToken". I send my trade offer to my friend and this is not important what I use like parameter for function. If I send my trade offer to stranger with wrong token I get error Error: There was an error sending your trade offer. Please try again later. (15).

[waylaidwanderer]

Before echo curl_error($ch);, can you also echo $url;?

[saqwel]

This is last $url before error:
https://steamcommunity.com/mobileconf/conf?p=android:fab585dd-d3ce-85dd-85dd-85ddd3ce7d34&a=0&k=XDxAON/kRTpewIqWyz2cdHOKQYg=&t=1456278550&m=android&tag=conf

@saqwel &a parameter shouldn't be 0.
