 #1.打开登陆页面

 wd = webdriver.Chrome()

 wd.implicitly_wait(10)

 wd.get('https://mail.qq.com/')

 #2.切换到账号密码登陆

 login_frame = wd.find_element_by_id('login_frame')

 wd.switch_to.frame(login_frame)

 wd.find_element_by_id('switcher_plogin').click()

 #3.输入账号密码

 u = wd.find_element_by_id('u')

 u.send_keys('')#---------------此处填QQ号

 p = wd.find_element_by_id('p')

 p.send_keys('')#----------------此处填QQ邮箱密码

 #4.点击登陆按钮

 wd.find_element_by_id('login_button').click()

 #5.点击收信

 wd.find_element_by_id('folder_1').click()

 #6.切换到收信iframe框架里

 main_frame = wd.find_element_by_id('mainFrame')

 wd.switch_to.frame(main_frame)

 #获取第一个tab页

 h = wd.current_window_handle

 #通过css选择器，找到我们邮件列表里面的内容

 email_eles = wd.find_elements_by_css_selector('.toarea .F, .toarea .M')

 email_eles_count = len(email_eles)

 #遍历每一封邮件

 for i in range(email_eles_count):

     #获取邮件列表的邮件项

     email_ele = wd.find_elements_by_css_selector('.toarea .F, .toarea .M')[i]

     #右击邮件项

     ActionChains(wd).context_click(email_ele).perform()

     #然后选择在新窗口打开

     wd.find_elements_by_css_selector('.menu_item')[1].click()

     #切换到邮件详情页tab

     email_detail_handle = wd.window_handles[2]#----------此处的数字个人可能不同，1或者2，可自行调试

     wd.switch_to.window(email_detail_handle)

     #切换到内容部分

     main_frame = wd.find_element_by_id('mainFrame')

     wd.switch_to.frame(main_frame)

     #获取邮件的标题

     subject = wd.find_element_by_id('subject').text

     #获取邮件的内容

     # content = wd.find_element_by_id('mainContentContainer').text

     print(subject)

     #关闭tab页

     wd.close()

     #回到第一个tab页，即邮件列表tab

     wd.switch_to.window(h)

     #又切换到列表部分

     main_frame = wd.find_element_by_id('mainFrame')

     wd.switch_to.frame(main_frame)

 wd.quit()
