解决Scrapy抓取中文结果保存为文件时的编码问题

 1 import json
 2 import codecs

 5 # Define your item pipelines here

 7 # Don't forget to add your pipeline to the ITEM_PIPELINES setting

11 class PandaPipeline(object):
12     def __init__(self):
13         self.file = codecs.open('pandaow.json', 'w', encoding='utf-8')
14 
15     def process_item(self, item, spider):
16         line = json.dumps(dict(item),ensure_ascii=False) + '
'
17         # print line
18         # self.file.write(line.decode("unicode_escape"))
19         self.file.write(line)
20         return item
21 
22     def spider_closed(self, spider):
23         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
