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

    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_7\chromedriver_win32\chromedriver.exe

    3. 创建一个chrome浏览器实例：

        driver = webdriver.Chrome('D:\python2_7\chromedriver_win32\chromedriver') ##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_7\chromedriver_win32\chromedriver')  ##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_7\install\lib\site-packages\selenium-2.48.0-py2.7.egg\selenium\webdriver\chrome\webdriver.py", line 88, in quit

        #       self.service.stop()

        #   File "D:\python2_7\install\lib\site-packages\selenium-2.48.0-py2.7.egg\selenium\webdriver\chrome\service.py", line 111, in stop

        #       url_request.urlopen("http://127.0.0.1:%d/shutdown" % self.port)

        #   File "D:\python2_7\install\lib\urllib2.py", line 126, in urlopen

        #       return _opener.open(url, data, timeout)

        #   File "D:\python2_7\install\lib\urllib2.py", line 397, in open

        #       response = meth(req, response)

        #   File "D:\python2_7\install\lib\urllib2.py", line 510, in http_response

        #       'http', request, response, code, msg, hdrs)

        #   File "D:\python2_7\install\lib\urllib2.py", line 435, in error

        #       return self._call_chain(*args)

        #   File "D:\python2_7\install\lib\urllib2.py", line 369, in _call_chain

        #       result = func(*args)

        #   File "D:\python2_7\install\lib\urllib2.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()
