python 序列转json序列化和编码问题

python序列转json

遇到的问题 序列里放的是对象 转json报错 XXX is not JSON serializable

解决办法 参考http://blog.csdn.net/jerry_1126/article/details/76409042

需要为Man专门写一个转换函数，再把函数传进去即可：

#coding: utf-8
# 文章类定义
class News(object):
def __init__(self):
self.url = None
self.title = None
self.author = None
self.date = None
self.about = None
self.content = None
self.picurl = None

#此方法写在调用类文件中
def obj2json(obj):
return {
"url":obj.url,
"title":obj.title,
"author":obj.author,
"date":obj.date,
"about":obj.about,
"content":obj.content,
"picurl":obj.picurl
}

#...
print(outlist[0].title)
jsonstr = json.dumps(outlist,default=obj2json,ensure_ascii=False)  #ensure_ascii=False 中文编码问题

t = json.dumps(r, ensure_ascii=False)
