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). 两者似乎都可以互换使用来设置超时以通过 加载 URL driver.get(URL),但有时也可以一起使用。

方案 1

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

方案 2

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

这两种情况有何不同?哪些情况会在一种情况下触发超时,而在另一种情况下不会?

根据Selenium-Python API Docs set_page_load_timeout(n)set_script_timeout(n)两者都是超时方法,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)设置在引发错误之前等待页面加载完成的时间量,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'})

在这里你可以找到一个详细的讨论set_page_load_timeout

set_script_timeout(time_to_wait)

set_script_timeout(time_to_wait)设置脚本在execute_async_scriptJavascript / AJAX 调用)调用期间在抛出错误之前应等待的时间量,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})
