Question

我知道这个问题已被多次询问，我已经检查过但找不到解决方案。以上错误并不常见，有时我得到它，所以我无法弄清楚它为什么会发生。执行下面的行后代码

 driver.get(first_url)
    #here i open forst url the perform some operation    
    main_window =driver.current_window_handle
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + "t")
    #above line opens a new tab 
    # Put focus on current window which will, in fact, put focus on the current visible tab
    main_window_new =driver.current_window_handle
    driver.switch_to_window(main_window_new )
    time.sleep(1)
    driver.get(second_url)
    #opening new tab in the existing browser 
    time.sleep(2)
    json_str=driver.find_element_by_tag_name('body').text
    time.sleep(1)
    print json
    # Close current tab
    driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 'w')

    # Put focus on current window which will be the window opener
    driver.switch_to_window(main_window)

我收到此错误

感谢任何帮助。

如果只有一个标签打开，下面一行会关闭浏览器。

# remove that line and run your code. You will not see this error again.
driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + 'w')
