本节重点：
键盘按键用法
键盘组合键用法
send_keys() 输入中文运行报错问题
键盘按键键用法：
#coding=utf-8
from selenium import webdriver
from selenium.webdriver.common.keys import Keys #需要引入keys包
import os,time driver = webdriver.Firefox()
driver.get("http://passport.kuaibo.com/login/?referrer=http%3A%2F%2Fwebcloud.kuaibo.com%2F") time.sleep(3)
driver.maximize_window() # 浏览器全屏显示 driver.find_element_by_id("user_name").clear()
driver.find_element_by_id("user_name").send_keys("fnngj") #tab的定位相相于清除了密码框的默认提示信息，等同上面的clear()
driver.find_element_by_id("user_name").send_keys(Keys.TAB)
time.sleep(3)
driver.find_element_by_id("user_pwd").send_keys("123456") #通过定位密码框，enter（回车）来代替登陆按钮
driver.find_element_by_id("user_pwd").send_keys(Keys.ENTER)
'''
#也可定位登陆按钮，通过enter（回车）代替click()
driver.find_element_by_id("login").send_keys(Keys.ENTER)
'''
time.sleep(3) time.sleep(3)
driver.quit() |
要想调用键盘按键操作需要引入keys包：
from selenium.webdriver.common.keys import Keys
通过send_keys()调用按键：
send_keys(Keys.TAB) # TAB
send_keys(Keys.ENTER) # 回车
注意：这个操作和页面元素的遍历顺序有关，假如当前定位在账号输入框，按键盘的tab键后遍历的不是密码框，那就不法输入密码。 假如输入密码后，还有需要填写验证码，那么回车也起不到登陆的效果。
这并不是一种好的方法，这里只是为了验证单个按键的用法
键盘组合键用法：
#coding=utf-8
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import os,time driver = webdriver.Firefox() driver.get(http://www.baidu.com) #输入框输入内容
driver.find_element_by_id("kw").send_keys("selenium")
time.sleep(3) #ctrl+a 全选输入框内容
driver.find_element_by_id("kw").send_keys(Keys.CONTROL,'a')
time.sleep(3) #ctrl+x 剪切输入框内容
driver.find_element_by_id("kw").send_keys(Keys.CONTROL,'x')
time.sleep(3) #输入框重新输入内容，搜索
driver.find_element_by_id("kw").send_keys(u"虫师 cnblogs")
driver.find_element_by_id("su").click() time.sleep(3)
driver.quit() |
上面的操作没有实际意义，但向我们演示了键盘组合按键的用法。
输入中文问题
顺便解决了一个困扰我到现的一个输入中文件的问题。selenium2 python在send_keys()中输入中文一直报错，其实前面加个小u 就解决了：
send_keys(u"输入中文")
基本上键盘上所有的按键都可以模拟
