封装后提示找不到‘userId’

Question

#这是封装代码，跟老师的一样
def switch_windows(self,title_name=None):
handle_list = self.driver.window_handles
current_handle = self.driver.current_window_handle
for i in handle_list:
if i != current_handle:
time.sleep(1)
self.driver.switch_to.window(i)
if self.assert_title(‘title_name’):
break
time.sleep(2)
self.driver.find_element_by_id(‘userId’).send_keys(‘test’)
time.sleep(2)

#执行代码：
selfnium_driver = SeleniumDriver(‘chrome’)
print(selfnium_driver.open_url_is_true(‘http://www.imooc.com’,‘程序员’))
time.sleep(60)
selfnium_driver.switch_windows(‘网站连接’)
time.sleep(3)
selfnium_driver.close_driver()

Unable to locate element: {“method”:“css selector”,“selector”:"[id=“userId”]"}
没有找到这个元素，你看你定位方式为啥userid，这个不应该是我们先去配置文件通过userid拿到email这样的定位值么

  封装前也是这样写，是能正常通过userId定位到微博账户名输入框的，为什么拿到这边封装就不可以了呢？而且代码完全跟老师写的一样啊

  你封装需要把readini那个也要封装啊，userid 这样的定位信息要有，你看我们是不是保存了一个变例如useremail=id>rmail这样的信息，这里拿到usermail然后去拆分
