利用python爬取电影天堂搜索部分，并利用pyqt可视化

爬虫部分

def crawls_home(film_name):
    name = film_name.encode('gb2312')
    name = str(name)[1:]
    name = re.sub(r'\\x','%',name)
    name = eval(name).upper() #关键字处理
    url = "http://s.ygdy8.com/plus/so.php?typeid=1&keyword={}".format(name)
    html = request_url(url)
    soup = BeautifulSoup(html,'lxml')
    div = soup.find('div',class_="co_content8")
    if div is None:
        return ['没有搜到相应电影']
    film_list = div.find_all('table',border="0",width="100%")
    return film_list

像电影天堂这种的爬虫应该算是很简单的了，这里需要注意的是电影天堂对输入的关键字采用的是gb2312编码，所以需要要对关键字做一些处理

 

可视化部分

主要是利用pyqt5进行简单粗糙的可视化

通过捕捉回车键或者点击确认弹出搜索电影的详细列表

可以点击超链接弹出详细介绍

通过点击超链接调用迅雷实现下载

完整代码如下：

crawlsdytt.py:

import requests
import re
from bs4 import BeautifulSoup

header = {"User-Agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) "
                            "Chrome/57.0.2987.110 Safari/537.36"}

#film_name = '猫和老鼠'

def request_url(url):  
    while True:
        try:
            r = requests.get(url,headers=header)
            if r.status_code == 200:
                r.encoding = 'gbk'
                return r.text
        except:
            pass

def crawls_home(film_name):
    name = film_name.encode('gb2312')
    name = str(name)[1:]
    name = re.sub(r'\\x','%',name)
    name = eval(name).upper()
    url = "http://s.ygdy8.com/plus/so.php?typeid=1&keyword={}".format(name)
    html = request_url(url)
    soup = BeautifulSoup(html,'lxml')
    div = soup.find('div',class_="co_content8")
    if div is None:
        return ['没有搜到相应电影']
    film_list = div.find_all('table',border="0",width="100%")
    return film_list

def crawls_single(url):
    html = request_url(url)
    soup = BeautifulSoup(html,'lxml')
    div = soup.find('div',id="Zoom")
    node = div.p
    href = re.search(r'href=\"(.*?)\"',str(div)).group(1)
    n_node = '\n\n{0}'.format(href)
    node = str(node) + n_node
    return node
