学了一阵子Python，拿来做个什么有意思的东西呢？爬糗百好了。爬到的内容，邮件分发出去。

然后又啃了两天的wxpython，做了个简易的邮件管理界面，能够在这里添加或者删除邮件，而且一键爬虫发送。

最后，索性封装成APP吧。又试了一把py2app。简单好用。

因为是让用户自行加入和删除邮箱。所以程序一定要兼顾到各种情况：比方输入的邮箱格式不合法。输入的邮箱里包括中文字符，分隔符不正确，删除了所有邮箱然后又要发邮件等问题。

首先是QiuBai.py：爬虫，正则匹配我们想要的内容。然后将内容稍作处理返回。

#!/usr/bin/env python# -*- coding: utf-8 -*-import reimport urllib2__author__ = 'Sophie2805'class FetchData(object):    def __init__(self,URL,referURL,pattern_1,pattern_2):        self.URL = URL        self.pattern_1 = pattern_1        self.patttern_2 = pattern_2        self.referURL = referURL    def getHtml(self):        headers = {            'User-Agent':'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6',            'Referer':self.referURL  #http://www.qiushibaike.com/        }        req = urllib2.Request(            url = self.URL, #http://www.qiushibaike.com/text            headers = headers)        return urllib2.urlopen(req).read()    def getData(self,html):        p_1 = re.compile(self.pattern_1)        div_content = p_1.findall(html.decode('utf8'))        row = 0        for m in range(len(div_content)):            div_content[m] = re.sub(self.patttern_2,'',div_content[m])            div_content[m] = ("---" + str(row+1) + "---" + div_content[m]).encode('utf-8')            row += 1        return div_content

接下来就是mail.py。注意。发送人的邮箱要检查下是否打开了SMTP协议

#!/usr/bin/env python# -*- coding: utf-8 -*-import smtplibfrom email.mime.text import MIMETextfrom email.header import Header__author__ = 'Sophie2805'class SMail:    def __init__(self):        self.sender = '***@qq.com'        self.receiver = ['***@163.com','***@qq.com']        self.subject = '糗百热门20条推送'        self.username = '***@qq.com'        self.password = '******'    def send_mail(self,msg):        try:            self.msg = MIMEText(msg,'plain','utf-8')            self.msg['Subject'] = Header(self.subject,'utf-8')            self.msg['To'] = ','.join(self.receiver)            self.msg['From'] = self.sender            self.smtp = smtplib.SMTP()            self.smtp.connect('smtp.qq.com')            self.smtp.login(self.username,self.password)            self.smtp.sendmail(self.msg['From'],self.receiver,self.msg.as_string())            self.smtp.quit()            return '1'        except Exception, e:            return str(e)

最后，用wxpython做了个简易的收件人管理界面，Spider_QiuBai.py，实现：添加邮件、删除邮件、一键爬虫发送糗百热门20条到邮件列表。

当然，为了程序正确执行，会有各种验证，比方输入的邮箱格式是否合法，发送时检查receiver列表是否为空等

程序比較简单，代码例如以下：

最后就是Python转APP了：

（1）在MAC终端里输入pip install py2app安装py2app

（2）创建setup.py，我的project位于/Users/Sophie/PycharmProjects/QiuBai，所以cd到这个路径下。然后vi setup.py。在这个文件中输入例如以下内容（提前准备个icns图标。放到project路径下）

"""

py2app build script for MyApplication

Usage:

python setup.py py2app

"""

from setuptools import setup

OPTIONS = {

'iconfile':'lemon.icns'

}

setup(

app=["Spider_QiuBai.py"],

options={'py2app': OPTIONS},

setup_requires=["py2app"],

)

（3）rm -rf build dist（假设反复多次打包的话。这个命令是须要的。第一次不须要）

（4）python setup.py py2app 用这个命令打包，打包好的app会存放在该路径下的dist路径下。我的例如以下：/Users/Sophie/PycharmProjects/QiuBai/dist

至此，这个小玩意儿已经做好了，当中略麻烦的可能就是正则还有界面了 Hope you enjoy it ^ ^
