爬取某视频网站的电影

1. 先使用抓包工具进行抓包分析，得到对应的接口
2. 直接用requests库来请求响应数据
3. 存入数据库

from functools import reduce

import pymysql
import requests
import json
# 链接数据库
def connectdatabase():
    conn = pymysql.connect(
        host='127.0.0.1',
        user='root',
        password='root',
        db='site',
        port=3308,
        charset='utf8'
    )
    return conn


# 请求对象并返回响应的内容
def handle_request(pageno):
    url='https://api.web.360kan.com/v1/filter/list?catid=1&rank=rankhot&cat=%E5%96%9C%E5%89%A7&year=&area=&act=&size=35&pageno={}&callback=__jp2'.format(pageno)
    resp = requests.get(url=url,headers={
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0'
        })
    return resp.text


def merge(x,y):
    return x+'/'+y


# 解析数据
def parse_data(movielist,sql,cusor):
    for move in movielist:
        # 演员列表(转化为json字符串)
        actorlist = move['actor']
        # 地区列表(遍历）
        arealist = move['area']
        # 电影简介(本身就是字符串)
        description = move['description']
        # 导演列表(转化为json字符串)
        directorlist = move['director']
        # 豆瓣评分
        doubanscore = move['doubanscore']
        # 电影类型列表(遍历)
        moviecategorylist = move['moviecategory']
        # 电影名
        movename = move['title']
        # 上映时间
        pubdate = move['pubdate']
        # 电影播放网站列表
        playlink_siteslist = move['playlink_sites']
        # 电影播放网站对应的地址链接
        # 播放网站及地址
        play_address = ''
        for site in playlink_siteslist:
            linkaddress = move['playlinks'][site]
            play_address += (site+':'+linkaddress+';')
        # 电影图片地址
        movecover = 'https:'+move['cover']
        # 电影评论
        movecomment = move['comment']
        # 遍历地区
        for area in arealist:
            # 遍历电影类型列表
            for movetype in moviecategorylist:
                cusor.execute(sql,(reduce(merge,actorlist),area,str(description),reduce(merge,directorlist),doubanscore,movetype,movename,pubdate,play_address,movecomment,movecover))
                print(reduce(merge,actorlist),area,str(description),reduce(merge,directorlist),doubanscore,movetype,movename,pubdate,play_address,movecomment,movecover)


# 连接数据库
conn = connectdatabase()
# 获取游标对象
cusor = conn.cursor()
#遍历页数
for i in range(1,20):
    # 电影列表
    movielist = json.loads((handle_request(i))[6:-2])['data']['movies']
    sql = "insert into movie values(NULL,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)"
    parse_data(movielist, sql, cusor)
conn.commit()
cusor.close()
conn.close()

总结：遇到数据无法回显时用抓包工具抓一下包，再去使用selenium,最后再去考虑js逆向的问题。
