Scrapy中将item字段转为简体or繁体

1. 安装hanziconv
安装一个简繁体转换的包:

pip install hanziconv

2. 自定义一个itempiples
找到项目中的pipelines.py文件

添加自定义的pipeline:

from hanziconv import HanziConv

class HanziconvPipeline(object):

def process_item(self, item, spider):
project_info = item['project_info']
for key, value in project_info.items():
if value is not None:
if isinstance(value, unicode):
value = HanziConv.toTraditional(str(value))
print key, value
project_info[key] = value
else: # 不为中文不处理
pass
else: # value为None 初始化为空串
project_info[key] = ""
return item

此代码为本人项目代码,判断value为unicode,则转换为繁体;

若要将繁体转换为简体,请将toTraditional改为toSimplified。

3. 配置项目pipeline
找到settings.py中的ITEM_PIPELINES
添加自定义的pipelines:

ITEM_PIPELINES = {
'scrapy_redis.pipelines.RedisPipeline': 400,
'<project_name>.pipelines.HanziconvPipeline': 300
}

:warning: <project_name>需手动修改为自己的项目名称!
