2、jingdong.py文件

# -*- coding: utf-8 -*- import scrapyimport logging import json logger = logging.getLogger(__name__) class JingdongSpider(scrapy.Spider):name = 'jingdong'allowed_domains = ['zhaopin.jd.com']start_urls = ['http://zhaopin.jd.com/web/job/job_list?page=1']pageNum = 1def parse(self, response):content = response.body.decode()content = json.loads(content)##########去除列表中字典集中的空值###########for i in range(len(content)):#list(content[i].keys()獲取當前字典中的keyfor key in list(content[i].keys()): #content[i]為字典if not content[i].get(key):#content[i].get(key)根據key獲取valuedel content[i][key] #刪除空值字典for i in range(len(content)):logging.warning(content[i])self.pageNum = self.pageNum+1if self.pageNum<=355:next_url = "http://zhaopin.jd.com/web/job/job_list?page="+str(self.pageNum)yield scrapy.Request(next_url,callback=self.parse)pass

3、注意點，針對jingdong的招聘翻頁是使用javascrapt，所以無法使用crawlscrapy進行自動翻頁，但是我們再network中查看其獲取數據的方法。

如：http://zhaopin.jd.com/web/job/job_list?page=2
