我抽奖是用的这个（

抽奖代码（js） 
function getPosts(url, callback) {
    var xhr = new XMLHttpRequest();
    xhr.open('GET', url, true);
    xhr.onreadystatechange = function () {
        if (xhr.readyState === 4 && xhr.status === 200) {
            var res = JSON.parse(xhr.responseText);
            callback(res.post_stream.posts);
        }
    };
    xhr.send();
}

function selectWinner(posts) {
    while (true) {
        var winner = posts[Math.floor(Math.random() * posts.length)];
        if (winner.post_number === 1) {
            console.log('抽中楼主（1楼），再抽一次！\n');
        } else {
            return winner;
        }
    }
}

function main() {
    let fullUrl = window.location.href;
    let baseUrlRegex = /^(https?:\/\/[^\/]+\/t\/topic\/\d+)/i;
    let match = fullUrl.match(baseUrlRegex);
    if (match && match[0]) {
        let baseUrl = match[0];
        let url = baseUrl + '.json?print=true';
        getPosts(url, function(posts) {
            let now = new Date();
            let year = now.getFullYear();
            let month = String(now.getMonth() + 1).padStart(2, '0');
            let date = String(now.getDate()).padStart(2, '0');
            let hours = String(now.getHours()).padStart(2, '0');
            let minutes = String(now.getMinutes()).padStart(2, '0');
            let seconds = String(now.getSeconds()).padStart(2, '0');
            let formattedTime = `${year}-${month}-${date} ${hours}:${minutes}:${seconds}`;
            console.log(`抽取时间为：${formattedTime}`)
            console.log(`一共有 ${posts.length} 个回复（含楼主，若抽中1楼，则再抽一次！）\n`);
            let winner = selectWinner(posts);
            console.log(`成功抽取第 ${winner.post_number} 楼，具体信息如下：\n`);
            console.log(winner.id, winner.display_username, winner.username, winner.cooked );
        });
}}

main();
