淘宝--模拟登录

使用pyppeteer模拟登录淘宝,获取cookie。

代码

# -*- coding: utf-8 -*-


import asyncio
from pyppeteer import launch
import time
from retry import retry      # 设置重试次数用的

count = 1


async def main(username, password, url):  # 主函数
    browser = await launch({'headless': True, 'args': ["--disable-infobars"]})  # headless设置无界面模式
    page = await browser.newPage()
    await page.goto(url)
    print('注入js')
    # 以下为插入中间js,将淘宝会为了检测浏览器而调用的js修改其结果。
    await page.evaluate('''() =>{ Object.defineProperties(navigator,{ webdriver:{ get: () => undefined } }) }''')

    try:
        await page.click('a.forget-pwd.J_Quick2Static')
        print('切换到密码登录页面')
        cookie = await login(page, username, password)
        return cookie
    except Exception as e:
        print('直接进入密码登录页面', e)
        cookie = await login(page, username, password)
        return cookie


async def login(page, username, password):  # 登录动作
    time.sleep(1)
    print('输入账号和密码')
    await page.type('input#TPL_username_1', username)
    time.sleep(1)
    await page.type('input#TPL_password_1', password)
    time.sleep(1)
    # 点击搜索按钮
    await page.click('button#J_SubmitStatic')
    time.sleep(2)
    print('点击登录')
    # 在while循环里强行查询某元素进行等待
    # while not await page.waitForXPath('//li[@id="J_SiteNavLogin"]'):
    #     return None
    print('登录成功!')

    ck = await get_cookie(page)
    await save_cookie(ck)
    return ck


async def get_cookie(page):  # 获取登录后cookie
    cookies_list = await page.cookies()
    cookies = ''
    for cookie in cookies_list:
        str_cookie = '{0}={1};'
        str_cookie = str_cookie.format(cookie.get('name'), cookie.get('value'))
        cookies += str_cookie
    print(cookies)
    return cookies


async def save_cookie(cookies):  # 保存到本地
    with open(r'./cookies.txt', 'w', encoding='utf-8') as f:
        f.write(cookies)
        print('保存成功')


@retry(tries=3)
def run():
    global count
    print('第%s次尝试请求' % count)
    username = ''  # 输入你的账号
    password = ''  # 输入你的密码
    url = 'https://login.taobao.com/member/login.jhtml?redirectURL=https://www.taobao.com/'
    # 协程,开启个无限循环的程序流程,把一些函数注册到事件循环上。当满足事件发生的时候,调用相应的协程函数。
    loop = asyncio.get_event_loop()
    m = main(username, password, url)
    ck = loop.run_until_complete(m)  # 将协程注册到事件循环,并启动事件循环
    count += 1
    return ck


def tb_cookies():
    ck = run()
    if ck is not None:
        return ck


if __name__ == '__main__':
    tb_cookies()

使用说明

在username和password处输入你的账号和密码

launch的headless默认设置为True是无界面模式,调试可以改为False有界面显示
