Python使用Selenium/PhantomJS

安装selenium：

1	pip install selenium

安装PhantomJS：

1 2 3 4

https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.7-linux-x86_64.tar.bz2 tar jxvf phantomjs-1.9.7-linux-x86_64.tar.bz2 cp phantomjs-1.9.7-linux-x86_64/bin/phantomjs /bin/ chmod 755 /bin/phantomjs

使用示例：

1 2 3 4 5

from selenium import webdriver driver = webdriver.PhantomJS() driver.get("http://www.baidu.com") data = driver.title print data

通过Remote Selenium Server：

1 2 3 4 5 6 7 8 9 10 11 12 13

from selenium import webdriver from selenium.webdriver.common.desired_capabilities import DesiredCapabilities driver = webdriver.Remote(   command_executor='http://192.168.1.3:4444/wd/hub',   desired_capabilities={'browserName': 'PhantomJS',                                   'version': '2',                                   'javascriptEnabled': True}) driver = webdriver.Remote(    command_executor='http://192.168.1.3:4444/wd/hub',    desired_capabilities=DesiredCapabilities.PHANTOMJS) driver.get("http://www.baidu.com") data = driver.title print data

PhantomJS和Firefox速度对比：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

import unittest from selenium import webdriver import time class TestThree(unittest.TestCase):       def setUp(self):         self.startTime = time.time()       def test_url_fire(self):         self.driver = webdriver.Firefox()         self.driver.get("http://www.qq.com")         self.driver.quit()       def test_url_phantom(self):         self.driver = webdriver.PhantomJS()         self.driver.get("http://www.qq.com")         self.driver.quit()       def tearDown(self):         t = time.time() - self.startTime         print "%s: %.3f" % (self.id(), t)         self.driver.quit   if __name__ == '__main__':     suite = unittest.TestLoader().loadTestsFromTestCase(TestThree)     unittest.TextTestRunner(verbosity=0).run(suite)
