使用正则表达式，取得点击次数，函数抽离

1. 用正则表达式判定邮箱是否输入正确。

import re
email = '736583887@qq.com'
if re.match('^[0-9a-zA-Z_]{0,19}@[0-9a-zA-Z]{1,13}\.[com,cn,net]{1,3}$', email):
    print("true")
else:
    print("false")

2. 用正则表达式识别出全部电话号码。

import re
str = '''版权所有：广州商学院   地址：广州市黄埔区九龙大道206号 学校办公室：020-82876130   招生电话：020-82872773'''
tel = re.findall('\d[0-9]{0,2}-\d[0-9]{6,8}', str)
for i in tel:
    print(i)

3. 用正则表达式进行英文分词。re.split('',news)

import re
english='''Every single time you access a website, you leave tracks. Tracks that others can access. If you don't like the idea, find out what software can help you cover them. '''
word = re.split('[\s,.?\+]',english)
for i in word:
    print(i)

4. 使用正则表达式取得新闻编号

newsUrl = ' http://news.gzcc.cn/html/2018/xiaoyuanxinwen_0401/9163.html'
newsId = re.search('\_(.*).html', newsUrl).group(1).split('/')[-1]
print(newsId)　

5. 生成点击次数的Request URL

import re
newsUrl = ' http://news.gzcc.cn/html/2018/xiaoyuanxinwen_0401/9163.html'
newsId = re.search('\_(.*).html', newsUrl).group(1).split('/')[-1]
url = ('http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(newsId))
print(url)

6. 获取点击次数

import requests
import re
newsUrl = ' http://news.gzcc.cn/html/2018/xiaoyuanxinwen_0401/9163.html'
newsId = re.search('\_(.*).html', newsUrl).group(1).split('/')[-1]
res = requests.get('http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(newsId))
count = int(res.text.split('.html')[-1].lstrip("(')").rstrip("');"))
print(count)

7. 将456步骤定义成一个函数 def getClickCount(newsUrl):

def getClickCount(newsUrl):
    newsId = re.search('\_(.*).html', newsUrl).group(1).split('/')[-1]
    res = requests.get('http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(newsId))
    count = int(res.text.split('.html')[-1].lstrip("(')").rstrip("');"))
    return count

8. 将获取新闻详情的代码定义成一个函数 def getNewDetail(newsUrl):

def getNewDetail(newsUrl):
    res = requests.get(newsUrl)
    res.encoding = 'utf-8'
    soup = BeautifulSoup(res.text, 'html.parser')

    title = soup.select(".show-title")[0].text
    content = soup.select("#content")[0].text
    info = soup.select(".show-info")[0].text

    dt = datetime.strptime(info.lstrip('发布时间:')[0:19], '%Y-%m-%d %H:%M:%S')
    if info.find('作者：')>0:
        author = info[info.find('作者：'):].split()[0].lstrip('作者：')
    else:
        author = 'none'
    if info.find('审核：')>0:
        auditing = info[info.find('审核：'):].split()[0].lstrip('审核：')
    else:
        auditing = 'none'
    if info.find('来源：')>0:
        source = info[info.find('来源：'):].split()[0].lstrip('来源：')
    else:
        source = 'none'
    if info.find('摄影：') > 0:
        photo = info[info.find('来源：'):].split()[0].lstrip('摄影：')
    else:
        photo = 'none'
    print(title,content)
    print(dt.strftime('%Y/%m/%d'), author, auditing, source,photo)

9. 取出一个新闻列表页的全部新闻 包装成函数def getListPage(pageUrl):

def getListPage(pageUrl):
    res = requests.get(pageUrl)
    res.encoding = 'utf-8'
    soup = BeautifulSoup(res.text, 'html.parser')
    for news in soup.select('li'):
        if len(news.select('.news-list-title')) > 0:
            newsUrl = news.select('a')[0].attrs['href']  # URL
            getNewDetail(newsUrl)

10. 获取总的新闻篇数，算出新闻总页数包装成函数def getPageN():

def getPageN():
    url = 'http://news.gzcc.cn/html/xiaoyuanxinwen/'
    res = requests.get(url)
    res.encoding = 'utf-8'
    soup = BeautifulSoup(res.text,'html.parser')
    n =int(soup.select('.a1')[0].text.rstrip('条'))// 10 + 1
    return n

11. 获取全部新闻列表页的全部新闻详情。

newsUrl='http://news.gzcc.cn/html/xiaoyuanxinwen/'
n=getPageN()
for i in range(2,n+1):
    print(i)
    pageUrl='http://news.gzcc.cn/html/xiaoyuanxinwen/{}.html'.format(i)
    getListPage(pageUrl)
