前戏
上篇文章说了selenium里的鼠标事件，在自动化中，键盘事件也是非常重要的，比如我们需要按回车键，ctrl+c复制等等操作，都离不开键盘事件，在selenium中，提供了Keys方法来供我们操作键盘
Keys
使用键盘完成复制，剪切，粘贴的功能
# 在百度搜索框输入 python ，复制粘贴搜狗输入框进行搜索 from selenium import webdriver from selenium.webdriver.common.keys import Keys from time import sleep driver = webdriver.Chrome() driver.get('http://www.baidu.com') driver.maximize_window() driver.find_element_by_css_selector('#kw').send_keys('python') sleep(2) driver.find_element_by_css_selector('#kw').send_keys(Keys.CONTROL, 'a') # 全选 driver.find_element_by_css_selector('#kw').send_keys(Keys.CONTROL, 'c') # 复制 driver.find_element_by_css_selector('#kw').send_keys(Keys.CONTROL, 'x') # 剪切 sleep(2) driver.get('http://www.sogou.com') driver.find_element_by_css_selector('.sec-input').send_keys(Keys.CONTROL, 'v') # 粘贴 sleep(2) driver.find_element_by_css_selector('#stb').click() sleep(2) driver.quit()
常用的按键
NULL = 'ue000' CANCEL = 'ue001' # ^break HELP = 'ue002' BACKSPACE = 'ue003' BACK_SPACE = BACKSPACE #删除键 TAB = 'ue004' #TAB键 CLEAR = 'ue005' RETURN = 'ue006' ENTER = 'ue007' #回车键 SHIFT = 'ue008' #Shift键 LEFT_SHIFT = SHIFT CONTROL = 'ue009' LEFT_CONTROL = CONTROL #Ctrl 键 ALT = 'ue00a' #Alt 键 LEFT_ALT = ALT PAUSE = 'ue00b' ESCAPE = 'ue00c' #ECS键 SPACE = 'ue00d' #空格键 PAGE_UP = 'ue00e' #PgUp 键 PAGE_DOWN = 'ue00f' #PgDwon 键 END = 'ue010' #END 键 HOME = 'ue011' #HOME 键 LEFT = 'ue012' #左键 ARROW_LEFT = LEFT UP = 'ue013' #上键 ARROW_UP = UP RIGHT = 'ue014' ARROW_RIGHT = RIGHT #右键 DOWN = 'ue015' #下键 ARROW_DOWN = DOWN INSERT = 'ue016' #insert键 DELETE = 'ue017' #del键 SEMICOLON = 'ue018' #';'键 EQUALS = 'ue019' #'='键 #数字键盘 NUMPAD0 = 'ue01a' #number pad keys NUMPAD1 = 'ue01b' NUMPAD2 = 'ue01c' NUMPAD3 = 'ue01d' NUMPAD4 = 'ue01e' NUMPAD5 = 'ue01f' NUMPAD6 = 'ue020' NUMPAD7 = 'ue021' NUMPAD8 = 'ue022' NUMPAD9 = 'ue023' MULTIPLY = 'ue024' # '*' 键 ADD = 'ue025' # '+' 键 SEPARATOR = 'ue026' #','键 SUBTRACT = 'ue027' # '-' 键 DECIMAL = 'ue028' # '.'键 DIVIDE = 'ue029' #'/'键 F1 = 'ue031' # function keys F2 = 'ue032' F3 = 'ue033' F4 = 'ue034' F5 = 'ue035' F6 = 'ue036' F7 = 'ue037' F8 = 'ue038' F9 = 'ue039' F10 = 'ue03a' F11 = 'ue03b' F12 = 'ue03c' META = 'ue03d' COMMAND = 'ue03d'
例子2
from selenium import webdriver import unittest, time from selenium.webdriver.common.keys import Keys class Test_dragpage(unittest.TestCase): def test_dragpageElement(self): url = 'http://www.sogou.com' self.driver = webdriver.Chrome() self.driver.get(url) self.driver.maximize_window() query = self.driver.find_element_by_id('query') # 通过WebDriver发送一个f12键 query.send_keys(Keys.F12) time.sleep(5) # 在按次f12 query.send_keys(Keys.F12) query.send_keys('selenium') # 按回车 query.send_keys(Keys.ENTER) time.sleep(3) test1 = Test_dragpage() test1.test_dragpageElement()
通过WebDriver内建的模块模拟组合键
from selenium import webdriver import unittest, time from selenium.webdriver import ActionChains from selenium.webdriver.common.keys import Keys class Test_dragpage(unittest.TestCase): def test_dragpageElement(self): url = 'http://www.baidu.com' self.driver = webdriver.Chrome() self.driver.get(url) input = self.driver.find_element_by_id('kw') input.send_keys('python') ActionChains(self.driver).key_down(Keys.CONTROL).send_keys('a').key_up(Keys.CONTROL).perform() time.sleep(2) ActionChains(self.driver).key_down(Keys.CONTROL).send_keys('x').key_up(Keys.CONTROL).perform() self.driver.get(url) self.driver.find_element_by_id('kw').click() ActionChains(self.driver).key_down(Keys.CONTROL).send_keys('v').key_up(Keys.CONTROL).perform() self.driver.find_element_by_id('su').click() test1 = Test_dragpage() test1.test_dragpageElement()
ActionChains(self.driver).key_down(Keys.CONTROL).send_keys('v').key_up(Keys.CONTROL).perform()，这行代码中，key_down(Keys.CONTROL)表示按下ctrl键，send_keys('v')类似模拟了V键，组合起来就是Ctrl+v，而key_down(Keys.CONTROL)表示释放Ctrl键
通过第三方库进行操作
需要安装pywin32

import win32api import win32con class KeyboardKeys(object): #模拟键盘按键类 VK_CODE={ 'enter':0x0D, 'ctrl':0x11, 'v':0x56 } @staticmethod def keyDown(keyName): #按下按键 win32api.keybd_event(KeyboardKeys.VK_CODE[keyName],0,0,0) @staticmethod def keyUp(keyName): #释放按键 win32api.keybd_event(KeyboardKeys.VK_CODE[keyName],0,win32con.KEYEVENTF_KEYUP,0) @staticmethod def oneKey(key): #模拟单个按键 KeyboardKeys.keyDown(key) KeyboardKeys.keyUp(key) @staticmethod def twoKeys(key1,key2): #模拟两个组合键 KeyboardKeys.keyDown(key1) KeyboardKeys.keyDown(key2) KeyboardKeys.keyUp(key2) KeyboardKeys.keyUp(key1)
Keybd_event（）共有四个参数：
第一个为按键的虚拟键值，如回车键为vk_return, tab键为vk_tab（其他具体的参见附录：常用模拟键的键值对照表）；
第二个参数为扫描码，一般不用设置，用0代替就行；
第三个参数为选项标志，如果为keydown则置0即可，如果为keyup则设成"KEYEVENTF_KEYUP"；
第四个参数一般也是置0即可。
调用
KeyboardKeys.oneKey('enter')
设置剪贴板
在进行自动化的时候，有时候要上传一个文件，这时会打开一个wins的窗口，但是selenium没有给我们提供操作wins窗口的方法，我们就要使用pywin32提供给我们的方法来操作
import win32clipboard as w import win32con class Clipboard(object): #模拟windows设置剪贴板 #读取剪贴板 @staticmethod def getText(): #打开剪贴板 w.OpenClipboard() #获取剪贴板中的数据 d=w.GetClipboardData(win32con.CF_TEXT) #关闭剪贴板 w.CloseClipboard() #返回剪贴板数据给调用者 return d #设置剪贴板内容 @staticmethod def setText(aString): #打开剪贴板 w.OpenClipboard() #清空剪贴板 w.EmptyClipboard() #将数据aString写入剪贴板 w.SetClipboardData(win32con.CF_UNICODETEXT,aString) #关闭剪贴板 w.CloseClipboard()
调用
Clipboard.setText(filePath)
