python扫描b站关注，并适当取关的脚本，playwright

1、先拿到bilibli的凭证吧

playwright codegen  https://www.bilibili.com/ --save-storage=auth.json

2、拿到凭证之后打开关注页面

playwright codegen --load-storage=auth.json  https://space.bilibili.com/750367/fans/follow

3、到关注页面最后去

from playwright.sync_api import Playwright, sync_playwright, expect


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context(storage_state="auth.json")
    page = context.new_page()
    page.goto("https://space.bilibili.com/750367/fans/follow")
    page.get_by_role("listitem", name="最后一页:").click()

    # ---------------------
    context.close()
    browser.close()


with sync_playwright() as playwright:
    run(playwright)

4、选择最后一个关注？

from playwright.sync_api import Playwright, sync_playwright, expect


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context(storage_state="auth.json")
    page = context.new_page()
    page.goto("https://space.bilibili.com/750367/fans/follow")
    page.get_by_role("listitem", name="最后一页:").click()
    page.locator("li").filter(has_text="大宝兔DOUBLE2").click()
    with page.expect_popup() as page1_info:
        page.locator("#page-follows").get_by_role("link", name="大宝兔DOUBLE2").click()
    page1 = page1_info.value
    page1.goto("https://space.bilibili.com/6432522/video")
    page3.close()
    page2.goto("https://www.bilibili.com/video/BV1sJ411p7rx/?spm_id_from=333.999.0.0&vd_source=77468d4e31f1f176d57fe63badf59fb4")
    page2.close()
    page1.close()
    with page.expect_popup() as page4_info:
        page.locator("#page-follows").get_by_role("link", name="大宝兔DOUBLE2").click()
    page4 = page4_info.value
    page4.goto("https://space.bilibili.com/6432522/video")

    # ---------------------
    context.close()
    browser.close()


with sync_playwright() as playwright:
    run(playwright)

5、可以拿到最新的时间了

from playwright.sync_api import Playwright, sync_playwright, expect
from datetime import datetime

def check_time(str_time):
    '''
    检查日期是否大于6个月的函数
    '''
    # 去除空白符
    clean_time = str_time.strip()

    # 尝试解析为 datetime 对象
    try:
        dt = datetime.strptime(clean_time, "%Y-%m-%d %H:%M:%S")
    except ValueError:
        return False

    # 获取当前时间
    now = datetime.now()

    # 计算时间差
    delta = dt - now

    if delta.total_months() > 6:
        return True
    else:
        return False


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context(storage_state="auth.json")
    page = context.new_page()
    page.goto("https://space.bilibili.com/750367/fans/follow")
    page.get_by_role("listitem", name="最后一页:").click()

    #等两秒钟这个页面正常加载后，这样不会出现一些麻烦的问题
    page.wait_for_timeout(2000)

    #取得当前所有up主的名字
    up_names = page.locator("css=.fans-name").all()

    for up_name in up_names:
        print(up_name.text_content())


    # 这些其实都是录制的，逻辑是有问题的
    page.locator("li").filter(has_text="大宝兔DOUBLE2").click()
    with page.expect_popup() as page1_info:
        page.locator("#page-follows").get_by_role("link", name="大宝兔DOUBLE2").click()
    page1 = page1_info.value
    page1.goto("https://space.bilibili.com/6432522/video")
    page1.close()

    with page.expect_popup() as page4_info:
        page.locator("#page-follows").get_by_role("link", name="大宝兔DOUBLE2").click()
    page4 = page4_info.value
    page4.goto("https://space.bilibili.com/6432522/video")

    page4.wait_for_timeout(5000)
    
    # 从这里开始实际上就是从最新的视频列表里拿到最新更新视频时间的子例程了
    dd = page4.locator("css=.time").first
    print("最新的一个视频的时间是：",dd.text_content().strip())
    print("是否大于六个月未更新？：",check_time(dd.text_content()))

    # ---------------------
    context.close()
    browser.close()


with sync_playwright() as playwright:
    run(playwright)

这个已经运行的非常好了

然后就到了取关动作的这个函数了

from playwright.sync_api import Playwright, sync_playwright, expect
from datetime import datetime

def check_time(str_time):
    '''
    检查日期是否大于6个月的函数
    '''
    # 去除空白符
    clean_time = str_time.strip()

    #处理“昨天这种特殊情况”
    if clean_time == "昨天":
        return False

    if "小时前" in clean_time:
        print("字符串中包含'小时前'")
        return False
    if "分钟前" in clean_time:
        print("字符串中包含'分钟前'")
        return False

    # 尝试解析为 datetime 对象
    try:
        dt = datetime.strptime(clean_time,"%Y-%m-%d")
    except ValueError:
        print("日期解析解析失败，尝试第二方案解析")
        clean_time = "2024-"+clean_time
        dt = datetime.strptime(clean_time,"%Y-%m-%d")
        

    # 获取当前时间
    now = datetime.now()

    # 计算时间差
    delta = now -dt

    # 计算月数差异
    months_diff = delta.days // 30  # 将天数差异转换为月数（假设一个月有 30 天）

    print(months_diff)
    
    if months_diff > 6:
        return True
    else:
        return False
