模拟登陆页面

页面分析

思路：
点击登陆按钮
选择要登陆的账号

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait

def login(driver = None):
    already_dic = {}
    # 创建一个字典，保存电脑登陆的QQ
    
    login_button = WebDriverWait(driver = driver,timeout = 100).until(EC.presence_of_element_located((By.XPATH,'//p[@class="user-info"]/a')))
    login_button.click()
    # 点击登录，获取电脑登陆的QQ
    
    already_login_number = WebDriverWait(driver = driver,timeout = 100).until(EC.presence_of_element_located((By.XPATH,'//div[@id="loginWin"]/iframe')))
    driver.get(url = already_login_number.get_attribute('src'))
    # 此步骤目的，是因为登录框是一个子页面，在上一级页面中获得到的这个子页面
    
    already_login_numbers = WebDriverWait(driver = driver,timeout = 100).until(EC.presence_of_all_elements_located((By.XPATH,'//span[contains(@class,"nick")]')))
    # 获取电脑登陆的QQ
    
    print('在以下账号中选择所需账号')
    for already_login_number in already_login_numbers:
        already_dic[already_login_number.get_attribute('innerText')] = already_login_number
        print(already_login_number.get_attribute('innerText'))
    QQ_NeedToLogin = input('需要登陆: ')
    # 通过获取键名，在 already_dic 获得相应的键值
    already_dic[QQ_NeedToLogin].click()
    # 模拟点击要登陆的QQ，达到登陆的效果
    time.sleep(1)

if __name__ == '__main__':
	start_url = 'https://qun.qq.com/index.html#click'  
	# 群首页，用来登陆账号
	driver = webdriver.Chrome(executable_path = './chromedriver.exe')
	# 因为selenium 需要用到浏览器、浏览器驱动，但是还要配置环境变量，很麻烦，如果这样指定 webdriver 路径的话，就可以省去那一步
	driver.get(url=start_url)
    login(driver=driver)

选择所需加载群

页面分析

打开群管理界面，会看到这样的信息，我们的目的是爬取已加入群的成员信息

?

def get_group_number(driver = None):
    group_number_dic = {}
    # 同样的，利用字典储存信息
    
    my_group_list = WebDriverWait(driver = driver,timeout = 100).until(EC.presence_of_all_elements_located((By.XPATH,'//ul[@class="my-group-list"]/li')))
    # 获取每个已加入群的节点信息
    
    print('在以下群中选择：')
    i = 1
    for my_group in my_group_list:
        try:
            group_number_dic[str(i)] = my_group
            print('第 %s 个--- '%str(i) + my_group.get_attribute('title') + ' ' + my_group.get_attribute('data-id'))
            i += 1
        except:
            continue
    # 打印出获得的群信息，获取所有的目标群
    
    group = input('获取群编号 : ')
    # 通过键名获取键值，得到要点击的目标
    
    group_number_dic[group].click()

    return driver

if __name__ == '__main__':
	member_url_test = 'https://qun.qq.com/member.html'
	driver.get(url = member_url_test)
    driver = get_group_number(driver=driver)

保存所需信息

页面分析

可以看到，是个动态加载的页面，因为用的是selenium，所以就没必要分析到底是通过请求那个url得到的信息，直接模拟滚动获取就可以了

?

def get_group_member(driver = None):
    driver.refresh()
    # 刷新一下界面，防止上一步点击过后，页面不更新的情况
    elem_end = WebDriverWait(driver = driver,timeout = 100).until(EC.presence_of_element_located((By.XPATH,'//td[@class="td-user-nick"]/img')))
    # 添加了等待，这个定位可以随便的选择，确保页面加载完毕的
    
    for i in range(10):
        time.sleep(0.5)
        driver.execute_script("var action=document.documentElement.scrollTop=10000")
        print('加载中······')
    # 这个滚动范围可以任选，因为每次会加载21个信息，我看过我加的群，在10次过后的成员基本属于潜水的人了，要不要的就无所谓了
    
    group_members = driver.find_elements_by_xpath('//tr[contains(@class,"mb")]')
    for group_member in group_members:
        try:
            data = group_member.text.split('
')[2].split(' ')[0]
            # 这一步，得到一个列表，从第一位开始分别是成员、群昵称、QQ号、性别、Q龄、入群时间、等级(积分)、最后发言，在这里我是只需要QQ号码
            #对于其他信息，根据自己需要，添加代码即可
            if data.isdigit() == True:
                with open('./record.txt','a',encoding = 'utf-8') as record:
                    record.write(data + '@qq.com')
                    record.write('

        except:
            continue
    print('Loaded')
