Code to claim SPS airdrop without login to Splinterlands

I will guide you how to claim sps airdrop by running this code:

exports.claim_sps = async (account) => {
    try {
        let ts = Date.now();
        const tx = 'hive' + account.username + ts;
        const sig = ecc.sign(tx, account.posting_key);

        let url = `https://ec-api.splinterlands.com/players/claim_sps_airdrop?platform=hive&address=${account.username}&sig=${sig}&ts=${ts}&username=${account.username}`;
        const {
            data
        } = await axios(url);

        if (data.success) {
            console.log(`${account.username.replace(' ', '').toLowerCase()} claimed ${data.data.qty} SPS`);
        } else {
            console.log(`${account.username.replace(' ', '').toLowerCase()}: No sps airdrop`);
        }

        return;
    } catch (error) {
        console.log(error.message);
        await new Promise((resolve) => setTimeout(resolve, 3000));
        return await this.claim_sps(account);
    }
};
