                             Python selenium chrome 环境配置
    
    一、参考文章:
        1. 记录一下python easy_install和pip安装地址和方法
            http://heipark.iteye.com/blog/1916758
        2. selenium + python自动化测试环境搭建
            http://www.cnblogs.com/fnng/archive/2013/05/29/3106515.html
        3. Python-selenium-Firefox-chrome-IE问题解决方法
            http://blog.csdn.net/lcm_up/article/details/38302143
        4. ChromeDriver - WebDriver for Chrome Getting started
            https://sites.google.com/a/chromium.org/chromedriver/getting-started
    
    二、Windows PowerShell
        1. 【win】键
        2. 键入:Windows PowerShell + 【Enter】键
    
    三、Python setuptools 18.4 安装:
        1. download:https://pypi.python.org/pypi/setuptools
        2. 跳到ez_setup.py所在的目录
        3. python .ez_setup.py
    
    四、Python pip 7.1.2 安装:
        1. download:https://pypi.python.org/pypi/pip#downloads
        2. 跳到解压出来的目录下的setup.py所在的目录
        3. python setup.py install
    
    五、Python selenium 2.48.0 安装:
        1. download:https://pypi.python.org/pypi/selenium
        2. 跳到解压出来的目录下的setup.py所在的目录
        3. python setup.py install
    
    六、chrome driver
        1. download:http://chromedriver.storage.googleapis.com/index.html?path=2.20/
        2. 解压拷贝文件到:D:python2_7chromedriver_win32chromedriver.exe
        3. 创建一个chrome浏览器实例:
            driver = webdriver.Chrome('D:python2_7chromedriver_win32chromedriver') ##可以替换为IE(), FireFox()
    
    七、Test Demo(请确保能访问Google):
        #!/usr/bin/python
        # -*- coding: utf-8 -*-
        
        import os
        from selenium import webdriver
        from selenium.common.exceptions import TimeoutException
        from selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0
        import time
        
        # Create a new instance of the browser driver
        driver = webdriver.Chrome('D:python2_7chromedriver_win32chromedriver')  ##可以替换为IE(), FireFox()
        
        # go to the google home page
        driver.get("http://www.google.com")
        
        # find the element that's name attribute is q (the google search box)
        inputElement = driver.find_element_by_name("q")
        
        # type in the search
        inputElement.send_keys("Cheese!")
        
        # submit the form. (although google automatically searches now without submitting)
        inputElement.submit()
        
        # the page is ajaxy so the title is originally this:
        print driver.title
        
        try:
            # we have to wait for the page to refresh, the last thing that seems to be updated is the title
            WebDriverWait(driver, 10).until(lambda driver : driver.title.lower().startswith("cheese!"))
        
            # You should see "cheese! - Google Search"
            print driver.title
        
        finally:
        
            #driver.quit()      # 当前使用 driver.quit()会导致如下错误
            #   Traceback (most recent call last):
            #   File "E:/python/Spider/Spider.py", line 39, in <module>
            #       driver.quit()
            #   File "D:python2_7installlibsite-packagesselenium-2.48.0-py2.7.eggseleniumwebdriverchromewebdriver.py", line 88, in quit
            #       self.service.stop()
            #   File "D:python2_7installlibsite-packagesselenium-2.48.0-py2.7.eggseleniumwebdriverchromeservice.py", line 111, in stop
            #       url_request.urlopen("http://127.0.0.1:%d/shutdown" % self.port)
            #   File "D:python2_7installliburllib2.py", line 126, in urlopen
            #       return _opener.open(url, data, timeout)
            #   File "D:python2_7installliburllib2.py", line 397, in open
            #       response = meth(req, response)
            #   File "D:python2_7installliburllib2.py", line 510, in http_response
            #       'http', request, response, code, msg, hdrs)
            #   File "D:python2_7installliburllib2.py", line 435, in error
            #       return self._call_chain(*args)
            #   File "D:python2_7installliburllib2.py", line 369, in _call_chain
            #       result = func(*args)
            #   File "D:python2_7installliburllib2.py", line 518, in http_error_default
            #       raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
            #   urllib2.HTTPError: HTTP Error 404: Not Found
        
            driver.close()
