概述
def process_item(self,item,spider):
import pdb; pdb.set_trace()
ID = str(uuid.uuid5(uuid.NAMESPACE_DNS,item['link']))我收到了这个错误：

exceptions.UnicodeDecodeError: 'ascii' codec can't decode byte 0xa7 in p
osition 1: ordinal not in range(128)我试图调试项目[‘link’]
这就是结果
-> ID = str(uuid.uuid5(uuid.NAMESPACE_DNS,item['link'])) (Pdb) item['link'] u'http://dubai.dubizzle.com/property-for-rent/residential/apartmentflat/2014/4/6 /palm-jumeirah-abu-keibal-3-br-maid-partial-2/?back=ZHViYWkuZHViaXp6bGUuY29tL3By b3BlcnR5LWZvci1yZW50L3Jlc2lkZW50aWFsL2FwYXJ0bWVudGZsYXQv&pos=1' (Pdb)
如你所见,项目[‘link’]是unicode
EDIT1
当我将项目[‘link’]更改为任何其他属性(如item [‘date’]时,代码完美无缺
str(uuid.uuid5(uuid.NAMESPACE_DNS,item['link'].encode('utf-8')))总结
