一位伙計自己開了個游戲室，想在群里拉點人，就用所學知識幫幫忙，于是就有了這篇文章，今天小編特此通過實例代碼給大家介紹下Python selenium 加載并保存QQ群成員去除其群主、管理員信息的示例代碼

模擬登陸頁面

頁面分析

思路：

點擊登陸按鈕選擇要登陸的賬號

代碼實現

# Author:smart_num_1# Blog:https://blog.csdn.net/smart_num_1# WeChat:Be_a_lucky_dogfrom selenium import webdriverfrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support import expected_conditions as ECfrom selenium.webdriver.support.ui import WebDriverWaitdef login(driver = None): already_dic = {} # 創(chuàng)建一個字典，保存電腦登陸的QQ login_button = WebDriverWait(driver = driver,timeout = 100).until(EC.presence_of_element_located((By.XPATH,’//p[@class='user-info']/a’))) login_button.click() # 點擊登錄，獲取電腦登陸的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’)) # 此步驟目的，是因為登錄框是一個子頁面，在上一級頁面中獲得到的這個子頁面 already_login_numbers = WebDriverWait(driver = driver,timeout = 100).until(EC.presence_of_all_elements_located((By.XPATH,’//span[contains(@class,'nick')]’))) # 獲取電腦登陸的QQ print(’在以下賬號中選擇所需賬號’) 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(’需要登陸: ’) # 通過獲取鍵名，在 already_dic 獲得相應的鍵值 already_dic[QQ_NeedToLogin].click() # 模擬點擊要登陸的QQ，達到登陸的效果 time.sleep(1)if __name__ == ’__main__’:start_url = ’https://qun.qq.com/index.html#click’ # 群首頁，用來登陸賬號driver = webdriver.Chrome(executable_path = ’./chromedriver.exe’)# 因為selenium 需要用到瀏覽器、瀏覽器驅動，但是還要配置環(huán)境變量，很麻煩，如果這樣指定 webdriver 路徑的話，就可以省去那一步driver.get(url=start_url) login(driver=driver)

選擇所需加載群

頁面分析

打開群管理界面，會看到這樣的信息，我們的目的是爬取已加入群的成員信息

代碼實現

# Author:smart_num_1# Blog:https://blog.csdn.net/smart_num_1# WeChat:Be_a_lucky_dogdef get_group_number(driver = None): group_number_dic = {} # 同樣的，利用字典儲存信息 my_group_list = WebDriverWait(driver = driver,timeout = 100).until(EC.presence_of_all_elements_located((By.XPATH,’//ul[@class='my-group-list']/li’))) # 獲取每個已加入群的節(jié)點信息 print(’在以下群中選擇：’) i = 1 for my_group in my_group_list: try: group_number_dic[str(i)] = my_group print(’第 %s 個--- ’%str(i) + my_group.get_attribute(’title’) + ’ ’ + my_group.get_attribute(’data-id’)) i += 1 except: continue # 打印出獲得的群信息，獲取所有的目標群 group = input(’獲取群編號 : ’) # 通過鍵名獲取鍵值，得到要點擊的目標 group_number_dic[group].click() return driverif __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

頁面分析

可以看到，是個動態(tài)加載的頁面，因為用的是selenium，所以就沒必要分析到底是通過請求那個url得到的信息，直接模擬滾動獲取就可以了

代碼實現

# Author:smart_num_1# Blog:https://blog.csdn.net/smart_num_1# WeChat:Be_a_lucky_dogdef get_group_member(driver = None): driver.refresh() # 刷新一下界面，防止上一步點擊過后，頁面不更新的情況 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，這個定位可以隨便的選擇，確保頁面加載完畢的 for i in range(10): time.sleep(0.5) driver.execute_script('var action=document.documentElement.scrollTop=10000') print(’加載中······’) # 這個滾動范圍可以任選，因為每次會加載21個信息，我看過我加的群，在10次過后的成員基本屬于潛水的人了，要不要的就無所謂了 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] # 這一步，得到一個列表，從第一位開始分別是成員、群昵稱、QQ號、性別、Q齡、入群時間、等級(積分)、最后發(fā)言，在這里我是只需要QQ號碼 #對于其他信息，根據自己需要，添加代碼即可 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’)
