哔哩哔哩签到 云函数脚本，可以在腾讯云、阿里云或者简单的青龙面板，设置定时器，定时执行签到即可，具体百度，云函数代码如下

// 主程序代码,支持多账号,详情见config文件

const axios = require('axios');

require('./config')

const cookieList = JSON.parse(process.env.BILIBILI_COOKIE); // 从环境变量中取cookie

let cookie = null

 
async function bilibiliCheckin() {

    const headers = {

    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.190 Safari/537.36',

    'Cookie': cookie,

    'Referer': 'https://www.bilibili.com/',

    'Origin': 'https://www.bilibili.com'

  }

    const result = await axios.get('https://api.live.bilibili.com/sign/doSign', { headers })[br]
    console.log(result.data);[br]
}

async function getBilibiliSignInfo() {

  const headers = {

    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.190 Safari/537.36',

    'Cookie': cookie,

    'Referer': 'https://www.bilibili.com/',

    'Origin': 'https://www.bilibili.com'

  }

  const response = await axios.get('https://api.live.bilibili.com/sign/GetSignInfo', { headers }); 

  console.log(response.data.data)

  if (response.data.code === 0) {

    console.log(`本月已签到${response.data.data.signDaysList.length}天，连续签到${response.data.data.hadSignDays}天`);

  } else {

    console.error(`获取签到信息失败，错误信息：${response.data.message}`);

  }

}

for (let i = 0; i < cookieList.length; i++) {

    cookie = cookieList[i]

    await bilibiliCheckin(); // 签到

    await getBilibiliSignInfo() // 获取用户信息

}

// config.js代码, cookie是数组格式，按照格式cv即可

process.env.BILIBILI_COOKIE = JSON.stringify([

    "buvid3=F5BEC679-CC8A-4493-A37D-08AE50C4649643611infoc; b_nut=1672998043; i-wanna-go-back=-1; _uuid=A3AD7C79-FEB2-BC4A-73F3-979310DCBA2B545839infoc; buvid4=48DAEF98-1574-AF0B-6DCE-0B46305D94EE92385-022052622-dIOlI2k6gFmDOYFSiwEwNw%3D%3D; SESSDATA=65feed2a%2C1688550052%2Cda9df%2A12; bili_jct=e6a95fc2c93f864e5a625c92808ccaec; DedeUserID=383663767; DedeUserID__ckMd5=61960ce3397f0763; sid=75r23dqi; b_ut=5; CURRENT_FNVAL=4048; rpdid=|(J~J)~mRJku0J'uY~kmm)|Y); nostalgia_conf=-1; buvid_fp_plain=undefined; LIVE_BUVID=AUTO9816749032393009; header_theme_version=CLOSE; fingerprint=7b87fa26bc923153a86acb6673ea51b6; buvid_fp=8e596d467b0475b019afa824b011e5ab; bsource=search_baidu; CURRENT_PID=a3bd06a0-ceda-11ed-8700-e7d269dad53a; PVID=1; FEED_LIVE_VERSION=V8; CURRENT_QUALITY=80; home_feed_column=5; b_lsid=953F2275_187D1CE7FD8; innersign=1; bp_video_offset_383663767=790322747756511200; browser_resolution=1707-412"

原脚本转自妖友 偏爱 ，目前是修改后的node脚本，有能力的可以改成python、php、java。
