Selenium .set_script_timeout(n) 有什么作用，它与 driver.set_page_load_timeout(n) 有何不同？

Question

在 python selenium 的上下文中，我不太了解 driver.set_page_load_timeout(n) VS 的确切区别。 driver.set_script_timeout(n)。两者似乎可以互换使用来设置超时以通过 driver.get(URL) 加载 URL，但有时也会一起使用。

场景 1:

driver.set_page_load_timeout(5)
website = driver.get(URL)
results = do_magic(driver, URL)

场景二:

driver.set_script_timeout(5)
website = driver.get(URL)
results = do_magic(driver, URL)

这两种情况有何不同？哪些情况在一种情况下会触发超时，而在另一种情况下不会？

根据 Selenium-Python API 文档 set_page_load_timeout(n) 和 set_script_timeout(n) 都是 timeout 方法，用于配置 webdriver 实例以在程序执行期间遵守。

set_page_load_timeout(time_to_wait)

set_page_load_timeout(time_to_wait) 设置在抛出错误之前等待页面加载完成的时间，定义为：

    def set_page_load_timeout(self, time_to_wait):
    """
    Set the amount of time to wait for a page load to complete
       before throwing an error.

    :Args:
     - time_to_wait: The amount of time to wait

    :Usage:
        driver.set_page_load_timeout(30)
    """
    try:
        self.execute(Command.SET_TIMEOUTS, {
        'pageLoad': int(float(time_to_wait) * 1000)})
    except WebDriverException:
        self.execute(Command.SET_TIMEOUTS, {
        'ms': float(time_to_wait) * 1000,
        'type': 'page load'})

的详细讨论

set_script_timeout(time_to_wait)

set_script_timeout(time_to_wait) sets the amount of time that the script should wait during an execute_async_script (Javascript / AJAX Call) 在抛出错误之前调用并且定义为：

    def set_script_timeout(self, time_to_wait):
    """
    Set the amount of time that the script should wait during an
       execute_async_script call before throwing an error.

    :Args:
     - time_to_wait: The amount of time to wait (in seconds)

    :Usage:
        driver.set_script_timeout(30)
    """
    if self.w3c:
        self.execute(Command.SET_TIMEOUTS, {
        'script': int(float(time_to_wait) * 1000)})
    else:
        self.execute(Command.SET_SCRIPT_TIMEOUT, {
        'ms': float(time_to_wait) * 1000})
