selenium 操控浏览器

如果是火狐浏览器那就最好啦，因为不用下载额外控件

from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium import webdriver
import time
import os
import urllib,urllib2

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

#不用下载额外的插件
driver = webdriver.Firefox()
driver.get('http://www.baidu.com')
assert u'百度' in driver.title



elem = driver.find_element_by_name("wd")
elem.send_keys(u"天空之城")
#elem.send_keys(Keys.RETURN)
time.sleep(5)
driver.close()


driver.quit()

如果是谷歌浏览器：

#需要下载chromedriver.exe
chromedriver = "C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe"
os.environ["webdriver.chrome.driver"] = chromedriver


driver = webdriver.Chrome(chromedriver)
driver.get('http://www.baidu.com')
assert u'百度' in driver.title
elem = driver.find_element_by_name("wd")
elem.send_keys("haha")

#elem.send_keys(Keys.RETURN)


driver.close()
driver.quit()

chromedriver.exe下载

如果是PhantomJS（无UI浏览器）：

下载、安装地址：http://phantomjs.org/download.html ，要下载一个phantomjs.exe，并设置好环境变量。

下面代码实现了，用PhantomJS解析JS，获取验证码URL，并下载验证码的功能：

        jpg.close()

        print e
