大家好，又见面了，我是你们的朋友全

。。。闲来无事，爬了一下我最爱的B站~~~卒 首先进入B站的番剧索引页 ps：以前经常浏览这个索引页找动漫看，所以熟练的操作~滑稽

翻页发现url链接并没有改变，用谷歌开发者工具network发现加载了XHR文件并返回json格式的响应

放到atom里看下数据是咋样的

要对其进行翻页处理，观察一下query string的规律，发现那么多个参数只有page这个参数是变化的

所以接下来都很好做了~嘻嘻 items.py

import scrapy
from scrapy import Field

class BilibiliItem(scrapy.Item):

    title = Field()
    cover = Field()
    sum_index = Field()
    is_finish = Field()
    link = Field()
    follow = Field()
    plays = Field()
    score = Field()
    _id = Field()

bzhan.py

import scrapy
import demjson #这个库要pip一哈
from scrapy.selector import Selector
from bilibili.items import BilibiliItem
from random import randint

class BzhanSpider(scrapy.Spider):
    name = 'bzhan'
    allowed_domains = ['bilibili.com']
    start_urls = ['https://bangumi.bilibili.com/media/web_api/search/result?season_version=-1&area=-1&is_finish=-1&copyright=-1&season_status=-1&season_month=-1&pub_date=-1&style_id=-1&order=3&st=1&sort=0&page=1&season_type=1&pagesize=20']

    def parse(self, response):
        json_content = demjson.decode(response.body)
        datas = json_content["result"]["data"]
        item = BilibiliItem()
        for data in datas:
            cover = data['cover']
            sum_index = data['index_show']
            is_finish = data['is_finish']
            is_finish = '已完结' if is_finish == 1 else '未完结'
            link = data['link']
            follow = data['order']['follow']
            plays = data['order']['play']

            try:
                score = data['order']['score']
            except:
                score = '未知'
            title = data['title']

            item['_id'] = title
            item['cover'] = cover
            item['sum_index'] = sum_index
            item['is_finish'] = is_finish
            item['link'] = link
            item['follow'] = follow
            item['plays'] = plays
            item['score'] = score
            item['title'] = title

            yield item
        urls = ['https://bangumi.bilibili.com/media/web_api/search/result?season_version=-1&area=-1&is_finish=-1&copyright=-1&season_status=-1&season_month=-1&pub_date=-1&style_id=-1&order=3&st=1&sort=0&page={0}&season_type=1&pagesize=20'.format(k) for k in range(2,156)]
        for url in urls:
            request = scrapy.Request(url,callback=self.parse)
            yield request

利用python对象字典的方式进行解析。。不难

piplines.py

import pymongo

class BilibiliPipeline(object):
    def process_item(self, item, spider):
        client = pymongo.MongoClient('localhost', 27017)
        mydb = client['mydb']
        bilibili = mydb['bilibili']
        bilibili.insert_one(item)
        print(item)
        return item

settings.py略。。。。。。

结果可以爬取到三千多个数据

心疼我的b站一秒。。
