解决Scrapy抓取中文结果保存为文件时的编码问题

 import json
 import codecs
 
 # Define your item pipelines here
 #
 # Don't forget to add your pipeline to the ITEM_PIPELINES setting
 # See: http://doc.scrapy.org/en/latest/topics/item-pipeline.html
 
 class PandaPipeline(object):
     def __init__(self):
         self.file = codecs.open('pandaow.json', 'w', encoding='utf-8')
 
     def process_item(self, item, spider):
         line = json.dumps(dict(item),ensure_ascii=False) + '\n'
         # print line
         # self.file.write(line.decode("unicode_escape"))
         self.file.write(line)
         return item
 
     def spider_closed(self, spider):
         self.file.close()

将以上内容插入pipelines.py,同时在settings.py中加入

ITEM_PIPELINES = {
    'panda.pipelines.PandaPipeline': 300
}

以调用pipelines文件
