Python爬糗百热门20条并邮件分发+wxPython简易GUI+py2app转成可运行文件

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 re
import 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 smtplib
from email.mime.text import MIMEText
from 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:

        frame.Show()
        return True

if __name__ == "__main__":
    app = GetQiuBaiApp()
    app.MainLoop()


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 ^ ^
