问题
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.
Scenario 1:
driver.set_page_load_timeout(5)
website = driver.get(URL)
results = do_magic(driver, URL)
Scenario 2:
driver.set_script_timeout(5)
website = driver.get(URL)
results = do_magic(driver, URL)
How do both scenarios differ? Which situations trigger a timeout in one but not the other scenario?
回答1:
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)
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)
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})
