24/7 Python selenium "while true:" 脚本无法执行 driver.get("URL")

Question

这是一个奇怪的问题

我的脚本有一个 while True: 24/7 运行的脚本。它总是每隔sleep(55) 秒点击一次print ('False')，一旦current_time 在指定时间之间，它就会调用driver.get("URL") 并在网站上执行一些操作。

但有时它会遇到无法打开driver.get('https://www.instagram.com/accounts/login/?source=auth_switcher') 的错误并在下面打印错误。

Traceback (most recent call last):
  File "/home/matt/insta/users/nycforest/lcf.py", line 254, in <module>
    lcf_time(input_begin_time,input_end_time,input_begin_time2,input_end_time2)

我尝试在driver.get('URL') 之后添加driver.set_page_load_timeout(20)，但它遇到了上面的错误

    sleep(2)
    driver.get('https://www.instagram.com/accounts/login/?source=auth_switcher')
    driver.set_page_load_timeout(20)
    sleep(3)

    input_username = driver.find_element_by_name('username').send_keys(username)
    input_password = driver.find_element_by_name('password').send_keys(password)

    button_login = driver.find_element_by_css_selector('#loginForm > div > div:nth-child(3) > button')
    button_login.click()

# def other_functions()

driver = webdriver.Chrome(options=opts)

def lcf_time(time_begin1, time_end1, time_begin2, time_end2, curren_time=None):
    current_time = datetime.now().time()
    if time_begin1 < current_time < time_end1 or time_begin2 < current_time < time_end2:
        login()
        # other_functions()
        driver.close()
    else:
        print("False")


while True:
    lcf_time(input_begin_time,input_end_time,input_begin_time2,input_end_time2)
    sleep(55)

奇怪的是：我有几个不同的脚本运行具有不同变量的完全相同的脚本，有些脚本很好，而另一些则始终达到这 60%时间。我需要更可靠的方式来driver.get("URL") 24/7

这是兼容性问题吗？我是不是做错了什么？

您可以仅使用 Python 或“curl”命令来代替 Selenium。

通过这种方式，您可以创建一个 bash/shell 脚本以在需要时触发该脚本，而无需保持 IDE 运行。
