一位伙计自己开了个游戏室，想在群里拉点人，就用所学知识帮帮忙，于是就有了这篇文章，今天小编特此通过实例代码给大家介绍下Python selenium 加载并保存QQ群成员去除其群主、管理员信息的示例代码
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
代码实现
# Author:smart_num_1

# WeChat:Be_a_lucky_dog
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
代码实现
# Author:smart_num_1
# Blog:https://blog.csdn.net/smart_num_1
# WeChat:Be_a_lucky_dog
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
代码实现
# Author:smart_num_1
# Blog:https://blog.csdn.net/smart_num_1
# WeChat:Be_a_lucky_dog
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('\n')[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('\n')
except:
continue
print('Loaded')
