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

注

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

2- webdriver

这是selenium的核心，主要包括11个文件夹

chrome
chromium
common
edge
firefox
ie
remote
safari
support
webkitgtk
wpewebkit

浏览器包

其中chrome chromium edge firefox ie safari webkitgtk wpewebkit 这是8个典型的浏览器

每个目录下存在三个主要的文件

options.py
service.py
webdriver.py

其中有点特殊的就是

chromium多了remote_connection.py

firefox多了

extension_connection.py
firefox_binary.py
firefox_profile.py
remote_connection.py
webdriver_prefs.json

safari多了

permissions.py
remote_connection.py

通用包

主要是3个包，common和support和remote

这是selenium的核心功能所在

① chrome包

puml源码见附录

注

1. service的Service这个类原名是Service，但如果这么写，由于有重名就会关联错误
2. 下面展示了chrome下3个文件中每个类的继承关系

② common包

action_chains

alert

这个比较简单

一个类Alert包括

• 一个属性text

• 三个方法dismiss accept send_keys

by

一个类By

8个定位方式

ZENKAKU_HANKAKU = '\ue040'

③ remote包

webdriver

WebElement

④ support包

expected_conditions

relative_locator

2个函数with_tag_name和locate_with

一个类RelativeBy

主要是5个方法above、below、to_left_of、to_right_of、near

select

定义了一个Select类

3个属性options、all_selected_options、first_selected_option

七个方法select_by_value select_by_index select_by_visible_text deselect_all 和deselect_by_value deselect_by_index deselect_by_visible_text

wait

显式等待的核心逻辑

一个类WebDriverWait

2个方法until和until_not

其中until是核心

原始定义如下

    def until(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
        while True:
            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:

                break
        raise TimeoutException(message, screen, stacktrace)

核心是

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

这么解释

1. 用传过来的method，call它，传入self._driver

2. 得到一个value，如果有value就直接return

3. 如果没有得到就time.sleep(轮询间隔)

4. 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

1. 其中RemoteWebDriver是别名，实际是WebDriver，不过是remote下的，跟第一个不同

2. BaseWebDriver是个抽象基类

3. RemoteWebDriver中会执行self.start_session(capabilities, browser_profile)

4. start_session源码如下，作用就是用提供的预期能力值启动会话

   def start_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.
       """
       if not isinstance(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' not in 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 endpoint
       if not self.caps:
           self.caps = response.get('capabilities')

5. 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

1. 其中Command类定义了JsonWireProtocol，比如Command.W3C_MAXIMIZE_WINDOW='w3cMaximizeWindow'

2. 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)

3. 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

4. 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/"}
