騰訊云函數控制臺鏈接：https://console.cloud.tencent.com/scf/list

1. 新建云函數
2. 自定義創建，運行環境選擇php5
3. 填寫代碼，設置bduss(在代碼22行左右)

代碼：

<?php

/*定義自定義函數*/
function xCurl($url,$cookie=null,$postdata=null,$header=array()){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    if (!is_null($postdata)) curl_setopt($ch, CURLOPT_POSTFIELDS,$postdata);
    if (!is_null($cookie)) curl_setopt($ch, CURLOPT_COOKIE,$cookie);
    if (!empty($header)) curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 50);
    $re = curl_exec($ch);
    curl_close($ch);
    return $re;
};

function main_handler() {
    date_default_timezone_set('PRC');
    set_time_limit(0);

    $bduss='你的BDUSS';

4. 觸發管理，創建觸發器

觸發方式 定時觸發

觸發周期 自定義觸發周期

Cron表達式 0 30 8 * * * *

表示每天的08:30觸發,第一個0是秒

5. 函數管理，函數配置，環境配置，修改執行超時時間

默認3秒，可以設置成60秒，最高900秒

關注的吧非常多可以直接設置成900秒，不過一般用不了這么長時間

但也不宜過短，時間太短的過可能簽到不完全部吧
