2021年10约13日更新主程序，添加了图片展示功能，具体程序看本文末尾新加内容。
签名记录为 https://pa.ci/ljk/index.html
头像记录为 https://pa.ci/ljk/images.html

B站之前是直接提供api的，网址是docs.bilibili.cn，后来因为负载太高不对外开放了。所幸现在还有人在收集api放在github上。利用api解析出json格式的个人信息并抓取签名对应的sign文字。抓取使用的是python脚本，用crontab每15分钟运行一次，记录保存到csv文件里面。用PHP写了个简易的页面，将csv读取并展示出来，地址为https://pa.ci/ljk/index.html。

以下是python脚本，因为csv文件不大，所以没有用mysql，直接w/r一把梭。

#!/usr/bin python3

import csv
import requests
import time

url = 'https://api.bilibili.com/x/web-interface/card'
params = (
    ('mid', '23947287'),
)
headers = {
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0'
}
response = requests.get(url=url, params=params, headers=headers).json()
sign_text = response['data']['card']['sign']

file_path = r'record.csv'

with open(file_path, newline='', encoding='utf-8') as f:
  csv_reader = csv.reader(f)
  first_line = next(csv_reader)
  f.close()

if str(first_line[1]) != str(sign_text):
    time_update = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
    row = [time_update, sign_text]
    with open(file_path, 'r', encoding='utf-8') as readFile:
        rd = csv.reader(readFile)
        lines = list(rd)
        lines.insert(0, row)
    with open(file_path, 'w', newline='', encoding='utf-8') as writeFile:
        wt = csv.writer(writeFile)
        wt.writerows(lines)
    readFile.close()
    writeFile.close()

以下是PHP页面，直接读csv就完事了，现在文件不大响应速度还行，不知道以后文件太大会不会高io拖垮服务器。

更新功能，现在可以同时记录签名和头像。
python写的主程序如下：

#!/usr/bin python3

import os
from pathlib import Path
import csv
import requests
import time



url = 'https://api.bilibili.com/x/web-interface/card'

params = (
    ('mid', '23947287'),
)

headers = {
        "user-agent": ""
}

response = requests.get(url=url, params=params, headers=headers).json()

sign_text = response['data']['card']['sign']
avatar_url = response['data']['card']['face']

avatar_name = Path(avatar_url)
file_name = avatar_name.name

file_path = r'time.csv'

with open(file_path, newline='', encoding='utf-8') as f:
  csv_reader = csv.reader(f)
  first_line = next(csv_reader)
  f.close()

if str(first_line[1]) != str(sign_text):
    time_update = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
    row = [time_update, sign_text]
    with open(file_path, 'r', encoding='utf-8') as readFile:
        rd = csv.reader(readFile)
        lines = list(rd)
        lines.insert(0, row)
    with open(file_path, 'w', newline='', encoding='utf-8') as writeFile:
        wt = csv.writer(writeFile)
        wt.writerows(lines)
    readFile.close()
    writeFile.close()

file_path_avatar = r'avatar.csv'

with open(file_path_avatar, newline='', encoding='utf-8') as f:
    csv_reader = csv.reader(f)
    first_line = next(csv_reader)
    f.close()

if str(first_line[1]) != str(file_name):
    save_path = r'images/'
    completeName = os.path.join(save_path, file_name)
    response = requests.get(avatar_url)
    file = open(completeName, "wb")
    file.write(response.content)
    file.close()

    time_update = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
    row = [time_update, file_name]
    with open(file_path_avatar, 'r', encoding='utf-8') as readFile:
        rd = csv.reader(readFile)
        lines = list(rd)
        lines.insert(0, row)
    with open(file_path_avatar, 'w', newline='', encoding='utf-8') as writeFile:
        wt = csv.writer(writeFile)
        wt.writerows(lines)
    readFile.close()
    writeFile.close()

PHP写的图片展示，最新的放在最上面。
