selenium库浅析，基于4.3

selenium库浅析

基于4.3

pip install selenium

安装好后，在sitepackages下

2个主要的目录，

common

和

webdriver

1- common

该目录一共就一个模块

exceptions.py

① exceptions.py

其中定义了

32个异常

，竟然有个同学面试的时候被问过
异常说明WebDriverException主异常，下面的都继承于它InvalidSwitchToTargetExceptionThrown when frame or window target to be switched doesn’t exist.NoSuchFrameExceptionThrown when frame target to be switched doesn’t exist.NoSuchWindowExceptionThrown when window target to be switched doesn’t exist.NoSuchElementExceptionThrown when element could not be found.NoSuchAttributeExceptionThrown when the attribute of element could not be found.NoSuchShadowRootExceptionThrown when trying to access the shadow root of an element when it does not have a shadow root attached.StaleElementReferenceExceptionThrown when a reference to an element is now “stale”.InvalidElementStateExceptionThrown when a command could not be completed because the element is in an invalid state.UnexpectedAlertPresentExceptionThrown when an unexpected alert has appeared.NoAlertPresentExceptionThrown when switching to no presented alert.ElementNotVisibleExceptionThrown when an element is present on the DOM, but it is not visible, and so is not able to be interacted with.ElementNotInteractableExceptionThrown when an element is present in the DOM but interactions with that element will hit another element due to paint orderElementNotSelectableExceptionThrown when trying to select an unselectable element.InvalidCookieDomainExceptionThrown when attempting to add a cookie under a different domain than the current URL.UnableToSetCookieExceptionThrown when a driver fails to set a cookie.RemoteDriverServerException源码没有给

__doc__

TimeoutExceptionThrown when a command does not complete in enough time.MoveTargetOutOfBoundsExceptionThrown when the target provided to the

ActionsChains

move() method is invalid, i.e. out of document.UnexpectedTagNameExceptionThrown when a support class did not get an expected web element.InvalidSelectorExceptionThrown when the selector which is used to find an element does not return a WebElementImeNotAvailableExceptionThrown when IME support is not available.ImeActivationFailedExceptionThrown when activating an IME engine has failed.InvalidArgumentExceptionThe arguments passed to a command are either invalid or malformed.JavascriptExceptionAn error occurred while executing JavaScript supplied by the user.NoSuchCookieExceptionNo cookie matching the given path name was found amongst the associated cookies of the current browsing context’s active document.ScreenshotExceptionA screen capture was made impossible.ElementClickInterceptedExceptionThe Element Click command could not be completed because the element receiving the events is obscuring the element that was requested to be clicked.InsecureCertificateExceptionNavigation caused the user agent to hit a certificate warning, which is usually the result of an expired or invalid TLS certificate.InvalidCoordinatesExceptionThe coordinates provided to an interaction’s operation are invalid.InvalidSessionIdExceptionOccurs if the given session id is not in the list of active sessions, meaning the session either does not exist or that it’s not active.SessionNotCreatedExceptionA new session could not be created.UnknownMethodExceptionThe requested command matched a known URL but did not match any methods for that URL.
注

Stale means the element no longer appears on the DOM of the page.
WebDriverException3个初始化参数，msg/screen/stacktrace，仅仅定义了__str__
UnexpectedAlertPresentException就它定义了自己的__str__，加了alert_text进来

2- webdriver

2个方法

until

和

until_not

其中

until

是核心

原始定义如下

defuntil(self, method, message:str=""):"""Calls the method provided with the driver as an argument until the \
        return value does not evaluate to ``False``.

        :param method: callable(WebDriver)
        :param message: optional message for :exc:`TimeoutException`
        :returns: the result of the last call to `method`
        :raises: :exc:`selenium.common.exceptions.TimeoutException` if timeout occurs
        """
        screen =None
        stacktrace =None

        end_time = time.monotonic()+ self._timeout
        from time import ctime
        whileTrue:try:
                value = method(self._driver)if value:return value
            except self._ignored_exceptions as exc:
                screen =getattr(exc,'screen',None)
                stacktrace =getattr(exc,'stacktrace',None)
            time.sleep(self._poll)if time.monotonic()> end_time:breakraise TimeoutException(message, screen, stacktrace)

核心是

        end_time = time.monotonic()+ self._timeout
        from time import ctime
        whileTrue:try:
                value = method(self._driver)if value:return value
            time.sleep(self._poll)if time.monotonic()> end_time:breakraise TimeoutException(message, screen, stacktrace)

这么解释

用传过来的method，call它，传入self._driver
得到一个value，如果有value就直接return
如果没有得到就time.sleep(轮询间隔)
加个判断如果当前时间超过了你的预设时间end_time(就是程序开始的时间+最大等待时间self._time_out)，那就退出循环，抛出TimeoutException异常

3- 实例浅析

下面的代码

from selenium import webdriver
driver = webdriver.Chrome()
driver.maximize_window()
driver.get('http://121.5.150.55:8090/')
driver.find_element('id','ls_username').send_keys('admin')
driver.find_element('id','ls_password').send_keys('123456')
driver.find_element('css selector','.pn.vm').click()

① 导包

from selenium import webdriver

你执行了

webdriver/__init__.py

这里做了很多命名，如，你才可以用上面代码的第二行

from.chrome.webdriver import WebDriver as Chrome

② 实例化某个浏览器

driver = webdriver.Chrome()

做完这个，正常情况你会打开一个浏览器

这是相对比较复杂的一个过程

其继承关系如下

注

其中RemoteWebDriver是别名，实际是WebDriver，不过是remote下的，跟第一个不同
BaseWebDriver是个抽象基类
RemoteWebDriver中会执行self.start_session(capabilities, browser_profile)
start_session源码如下，作用就是用提供的预期能力值启动会话

defstart_session(self, capabilities:dict, browser_profile=None)->None:"""
       Creates a new session with the desired capabilities.

       :Args:
        - capabilities - a capabilities dict to start the session with.
        - browser_profile - A selenium.webdriver.firefox.firefox_profile.FirefoxProfile object. Only used if Firefox is requested.
       """ifnotisinstance(capabilities,dict):raise InvalidArgumentException("Capabilities must be a dictionary")if browser_profile:if"moz:firefoxOptions"in capabilities:
               capabilities["moz:firefoxOptions"]["profile"]= browser_profile.encoded
           else:
               capabilities.update({'firefox_profile': browser_profile.encoded})
       w3c_caps = _make_w3c_caps(capabilities)
       parameters ={"capabilities": w3c_caps}
       response = self.execute(Command.NEW_SESSION, parameters)if'sessionId'notin response:
           response = response['value']
       self.session_id = response['sessionId']
       self.caps = response.get('value')# if capabilities is none we are probably speaking to# a W3C endpointifnot self.caps:
           self.caps = response.get('capabilities')

就是这句

response = self.execute(Command.NEW_SESSION, parameters)

③ driver操作

driver.maximize_window()
driver.get('http://121.5.150.55:8090/')
driver.find_element('id','ls_username').send_keys('admin')
driver.find_element('id','ls_password').send_keys('123456')
driver.find_element('css selector','.pn.vm').click()

上面所有的driver的操作本质都是类似的
操作源码driver.maximize_window()driver.execute(Command.W3C_MAXIMIZE_WINDOW,None)driver.get(url)driver.execute(Command.GET, {‘url’: url})driver.find_element(‘id’,‘ls_username’)driver.execute(Command.FIND_ELEMENT, { ‘using’: ‘id’, ‘value’: ‘ls_username’})[‘value’]

其中Command类定义了JsonWireProtocol，比如Command.W3C_MAXIMIZE_WINDOW='w3cMaximizeWindow'
而execute这个方法接收2个参数driver_command和params，核心是response = self.command_executor.execute(driver_command, params)
其中command_executor你可以理解为是chromedriver这个驱动(REST API SERVER)，虽然默认值是'http://127.0.0.1:4444' Grid的地址。它的本质会去调度self._request(command_info[0], url, body=data)这里跟requests库的调用就即可相似了，虽然底层的差异还是蛮多的
举个例子，调试第二行实例化得到的method/url/body分别是

POST 
http://localhost:11721/session 
{"capabilities":{"firstMatch":[{}], "alwaysMatch":{"browserName":"chrome", "pageLoadStrategy":"normal", "goog:chromeOptions":{"extensions":[], "args":[]}}}}

第三行最大化

POST http://localhost:11721/session/3e0775932ad7ee1828609d5e38bb6984/window/maximize {}

第四行

POST http://localhost:11721/session/3e0775932ad7ee1828609d5e38bb6984/url {"url":"http://121.5.150.55:8090/"}
