前戲
上篇文章說了selenium里的鼠標事件，在自動化中，鍵盤事件也是非常重要的，比如我們需要按回車鍵，ctrl+c復制等等操作，都離不開鍵盤事件，在selenium中，提供了Keys方法來供我們操作鍵盤
Keys
使用鍵盤完成復制，剪切，粘貼的功能
# 在百度搜索框輸入 python ，復制粘貼搜狗輸入框進行搜索 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') # 全選 driver.find_element_by_css_selector('#kw').send_keys(Keys.CONTROL, 'c') # 復制 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') # 粘貼 sleep(2) driver.find_element_by_css_selector('#stb').click() sleep(2) driver.quit()
常用的按鍵

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') # 通過WebDriver發送一個f12鍵 query.send_keys(Keys.F12) time.sleep(5) # 在按次f12 query.send_keys(Keys.F12) query.send_keys('selenium') # 按回車 query.send_keys(Keys.ENTER) time.sleep(3) test1 = Test_dragpage() test1.test_dragpageElement()
通過WebDriver內建的模塊模擬組合鍵
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()，這行代碼中，key_down(Keys.CONTROL)表示按下ctrl鍵，send_keys('v')類似模擬了V鍵，組合起來就是Ctrl+v，而key_down(Keys.CONTROL)表示釋放Ctrl鍵
通過第三方庫進行操作
需要安裝pywin32

import win32api import win32con class KeyboardKeys(object): #模擬鍵盤按鍵類 VK_CODE={ 'enter':0x0D, 'ctrl':0x11, 'v':0x56 } @staticmethod def keyDown(keyName): #按下按鍵 win32api.keybd_event(KeyboardKeys.VK_CODE[keyName],0,0,0) @staticmethod def keyUp(keyName): #釋放按鍵 win32api.keybd_event(KeyboardKeys.VK_CODE[keyName],0,win32con.KEYEVENTF_KEYUP,0) @staticmethod def oneKey(key): #模擬單個按鍵 KeyboardKeys.keyDown(key) KeyboardKeys.keyUp(key) @staticmethod def twoKeys(key1,key2): #模擬兩個組合鍵 KeyboardKeys.keyDown(key1) KeyboardKeys.keyDown(key2) KeyboardKeys.keyUp(key2) KeyboardKeys.keyUp(key1)
Keybd_event（）共有四個參數：
第一個為按鍵的虛擬鍵值，如回車鍵為vk_return, tab鍵為vk_tab（其他具體的參見附錄：常用模擬鍵的鍵值對照表）；
第二個參數為掃描碼，一般不用設置，用0代替就行；
第三個參數為選項標志，如果為keydown則置0即可，如果為keyup則設成"KEYEVENTF_KEYUP"；
第四個參數一般也是置0即可。

設置剪貼板
在進行自動化的時候，有時候要上傳一個文件，這時會打開一個wins的窗口，但是selenium沒有給我們提供操作wins窗口的方法，我們就要使用pywin32提供給我們的方法來操作
import win32clipboard as w import win32con class Clipboard(object): #模擬windows設置剪貼板 #讀取剪貼板 @staticmethod def getText(): #打開剪貼板 w.OpenClipboard() #獲取剪貼板中的數據 d=w.GetClipboardData(win32con.CF_TEXT) #關閉剪貼板 w.CloseClipboard() #返回剪貼板數據給調用者 return d #設置剪貼板內容 @staticmethod def setText(aString): #打開剪貼板 w.OpenClipboard() #清空剪貼板 w.EmptyClipboard() #將數據aString寫入剪貼板 w.SetClipboardData(win32con.CF_UNICODETEXT,aString) #關閉剪貼板 w.CloseClipboard()
調用
Clipboard.setText(filePath)
