python — selenium爬取微博指数

需要用到的工具:python(pymouse、selenium)、chrome、webdriver

使用的webdriver一定要和chrome的版本相匹配,具体的对应关系可以参考以下博客:http://blog.csdn.net/goblinintree/article/details/47335563。为了避免这个问题,最好直接使用最新的chrome和最新的webdriver。

以下代码是PyMouse的源码

# -*- coding: iso-8859-1 -*-

"""The goal of PyMouse is to have a cross-platform way to control the mouse.
PyMouse should work on Windows, Mac and any Unix that has xlib.

See http://code.google.com/p/pymouse/ for more information.
"""

import sys

class PyMouseMeta(object):

    def press(self, x, y, button = 1):
        """Press the mouse on a givven x, y and button.
        Button is defined as 1 = left, 2 = right, 3 = middle."""

        raise NotImplementedError

    def release(self, x, y, button = 1):
        """Release the mouse on a givven x, y and button.
        Button is defined as 1 = left, 2 = right, 3 = middle."""

        raise NotImplementedError

    def click(self, x, y, button = 1):
        """Click the mouse on a givven x, y and button.
        Button is defined as 1 = left, 2 = right, 3 = middle."""

        self.press(x, y, button)
        self.release(x, y, button)

    def move(self, x, y):
        """Move the mouse to a givven x and y"""

        raise NotImplementedError

    def position(self):
        """Get the current mouse position in pixels.
        Returns a tuple of 2 integers"""

        raise NotImplementedError

    def screen_size(self):
        """Get the current screen size in pixels.
        Returns a tuple of 2 integers"""

        raise NotImplementedError

if sys.platform.startswith(‘java‘):
    from java_ import PyMouse

elif sys.platform == ‘darwin‘:
    from mac import PyMouse

elif sys.platform == ‘win32‘:
    from windows import PyMouse

else:
    from unix import PyMouse

  由于是windows系统,所以pymouse需要调用windows的win32,否则无法正常使用。

  必须要安装win32相关的控件,对应的网址是https://sourceforge.net/projects/pywin32/files/pywin32/Build%20221/。请务必选择正确的版本,我的这部分代码使用的是python2.7+64位系统,所以选择的是pywin32-221.win-amd64-py2.7.exe。

  完成以上部分的内容之后正式进入到selenium+chrome+python+chrome的爬虫。
