python 模拟windows键盘按键的封装

代码：在执行的时候，把光标放在指定的地方，在此例中，点击运行后把光标放到结果区域，粘贴的时候是粘贴到光标所在的问题，如过是运行脚本在web元素输入框中输入的话，不能移动光标到其他位置

#encoding=utf-8
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):#对前两个方法的调用
        #模拟单个按键
        KeyboardKeys.keyDown(key)
        KeyboardKeys.keyUp(key)

    @staticmethod
    def twoKeys(key1,key2):#对前面函数的调用
        #模拟两个组合键
        KeyboardKeys.keyDown(key1)
        KeyboardKeys.keyDown(key2)
        KeyboardKeys.keyUp(key2)
        KeyboardKeys.keyUp(key1)

if __name__=='__main__':
    from util.clipboard import *
    from selenium import webdriver
    import time
    Clipboard.setText(u"hello world")
    time.sleep(3)
    # driver=webdriver.Firefox(executable_path=r'c:\geckodriver')
    # driver.get('http://www.baidu.com')
    # driver.find_element_by_xpath("//input[@id='kw']").click()
    # KeyboardKeys.twoKeys("ctrl","v")
    KeyboardKeys.twoKeys('ctrl','v')

结果：ok
