使用selenium模拟登陆淘宝报错

运行的时候报错：

EC.presence_of_element_located((By.CSS_SELECTOR, '.qrcode-login > .login-links > .forget-pws')))
网页上定位不到这个CSS_SELECTOR

是timeout exception，是超时了
应该“time.sleep”一会儿让它加载出来

根据你提供的错误信息，看起来是等待页面元素超时导致的错误。可以尝试增加等待时间或者使用更加精准的元素定位方式。

另外，你的代码中似乎没有将微博账号和密码传递给程序，建议在代码开头将这两个变量赋值。

修改后的代码如下：
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

class tb_infos:

# 初始化对象
def __init__(self):
   url = 'https://login.taobao.com/member/login.jhtml'
   self.url = url

   options = webdriver.ChromeOptions()
   options.add_experimental_option('prefs', {'profile.managed_default_content_settings.images': 2})
   options.add_experimental_option('excludeSwitches', ['enable-automation'])

   self.browser = webdriver.Chrome(options=options)
   self.wait = WebDriverWait(self.browser, 20)

# 登录淘宝
def login(self, wb_username, wb_password):

   self.browser.get(self.url)

   password_login = self.wait.until(
         EC.presence_of_element_located((By.CSS_SELECTOR, '.qrcode-login > .login-links > .forget-pws')))
   password_login.click()

   wb_login = self.wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '.weibo-login')))
   wb_login.click()

   wb_user = self.wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '.username > .W_input')))
   wb_user.send_keys(wb_username)

   wb_pwd = self.wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '.password > .W_input')))
   wb_pwd.send_keys(wb_password)

   submit = self.wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, '.btn-tip > a > span')))
   submit.click()

   tb_name = self.wait.until(EC.presence_of_element_located((By.CSS_SELECTOR,
                                                               '.site-nav-bd > .site-nav-bd-1 > li#J_SiteNavLogin > .site-nav-menu-hd > .site-nav-user > a.site-nav-login-info-nick')))
   print(tb_name.text)

if __name__ == '__main__':
wb_username = '微博账号'
wb_password = '微博密码'

a = tb_infos()
a.login(wb_username, wb_password)
其中，我增加了一个 login 方法的两个参数 wb_username 和 wb_password，并且在最后一行调用 login 方法时，将这两个参数传入方法中。
