Python编程学习利用Scrapy获取链家房源数据

 import scrapy

    
  
    
  
    
 class ScrapytestItem(scrapy.Item):
    
     # define the fields for your item here like:
    
     title = scrapy.Field()
    
     price = scrapy.Field()
    
     url = scrapy.Field()
    
    
    
    
    AI写代码python
    
    运行

 import json

    
  
    
 class ScrapytestPipeline(object):
    
     #打开文件
    
     def open_spider(self,spider):
    
     self.file = open('58_chuzu.txt','w',encoding='utf-8')
    
     print('文件被打开了')
