python 字符与字节 json序列和反序列及支持的类型

 

b = b"demo" 

s = "demo"

# 字符串转字节
s = bytes(s, encoding = "utf8")

s = str.encode(s)

# 字节转字符串 
s = str(b, encoding = "utf8")

s = bytes.decode(b)

 

json 序列与反序列化

name = {'name': "gggg"}
name01 = """{"name": "gggg"}"""
# 转化成字符串(序列化)
name_dumps = json.dumps(name)
# 转化成json格式(反序列化)
name01_loads = json.loads(name01)

# json.dumps 序列化时对中文默认使用的ascii编码.想输出真正的中文需要指定ensure_ascii=False：


print(type(name_dumps))
print(type(name01_loads))

 

js中处理json

序列化:
  Json.stringify()
反序列化
Json.parse()
