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

问题描述

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，但有时也可以一起使用.

In context of python selenium, I don't quite understand the exact difference of driver.set_page_load_timeout(n) VS. driver.set_script_timeout(n). Both seem to be used interchangeable to set a timeout to load an URL via driver.get(URL), but sometimes also together.

场景 1:

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

场景 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触发?

解决方案

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

As per the Selenium-Python API Docs set_page_load_timeout(n) and set_script_timeout(n) both are timeout methods which are used to configure the webdriver instance to abide by during the program execution.

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量，定义为:

set_page_load_timeout(time_to_wait) sets the amount of time to wait for a page load to complete before throwing an error and is defined as :

    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'})

Here you can find a detailed discussion on set_page_load_timeout

set_script_timeout(time_to_wait) 设置脚本在 execute_async_script (Javascript/AJAX Call) 在抛出错误之前调用，定义为:

set_script_timeout(time_to_wait) sets the amount of time that the script should wait during an execute_async_script (Javascript / AJAX Call) call before throwing an error and is defined as :

    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})
