【Python】从0开始写爬虫——转身扒豆瓣电影

豆瓣就比较符合这个“明人不说暗话”的原则。所以我们扒豆瓣，不多说，直接上代码

from scrapy import app
import re

header = {
    'User-Agent':
        'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36',
    'Host': 'movie.douban.com',
    'Accept-Language': 'zh-CN,zh;q=0.9'
}

movie_url = "https://movie.douban.com/subject/26985127/?from=showing"

m_id = re.search("[0-9]+", movie_url).group()

# 获取soup对象
soup = app.get_soup(url=movie_url, headers=header, charset="utf-8")
content = soup.find(id="content")

# 抓取电影名字和上映年份
m_name = content.find("h1").find("span").string
m_year = content.find(class_="year").string

# 抓取导演
info = content.find(id="info")
m_directer = info.find(attrs={"rel": "v:directedBy"}).string
# 上映日期
m_date = info.find(attrs={"property": "v:initialReleaseDate"}).string

# 类型
types = info.find_all(attrs={"property": "v:genre"}, limit=2)
m_types = []
for type_ in types:
    m_types.append(type_.string)


# 抓取主演，只取前面五个
actors = info.find(class_="actor").find_all(attrs={"rel": "v:starring"}, limit=5)
m_actors = []
for actor in actors:
    m_actors.append(actor.string)

# 片长
m_time = info.find(attrs={"property": "v:runtime"}).string
# m_adaptor = info.select()

print("id", m_id, "名称", m_name, "年份 ", m_year, "导演 ", m_directer, "主演", m_actors)
print("上映日期", m_date, "类型", m_types, "片长", m_time)

输出：

id 26985127 名称 一出好戏 年份  (2018) 导演  黄渤 主演 ['黄渤', '舒淇', '王宝强', '张艺兴', '于和伟']
上映日期 2018-08-10(中国大陆) 类型 ['剧情', '喜剧'] 片长 134分钟
