Person(user, "用户") System(system, "系统") Container(containerA, "数据转换模块") { Component(objectConverter, "对象转换器") } 模块差异 这里的类图展示了实现字符串转换的不同模块之间的关系: StringConverter+convert(obj)JsonConverter+toString(obj)CustomObjectConverter+serialize(obj) 特性拆解 在选择...
此外,我们还可以使用以下str()函数将Protobuf对象输出为人类可读的字符串: # serialize proto objectimportos out_dir ="proto_dump"withopen(os.path.join(out_dir,"person.pb"),"wb")asf:# binary outputf.write(person.SerializeToString())withopen(os.path.join(out_dir,"person.protobuf"),"w")asf:...
Serialize obj to a JSON formatted str.(字符串表示的json对象) Skipkeys: 默认值是False 如果dict的keys内的数据不是python的基本类型(str,unicode,int,long,float,bool,None)设置为False时,就会报TypeError的错误。 此时设置成True,则会跳过这类key ensure_ascii: 当它为True的时候 所有非ASCII码字符显示为...

1.python/google/protobuf/internal/type_checkers.py中,CheckValue函数是用来检查string类型赋值的,把“Ifthevalueisoftype'str'makesurethatitisin7-bitASCIIencoding”注释之后的全部去掉,这段的意思是当我们把utf8类型(即python的str类型)赋值给它时,它会首先尝试转unicode,这个是不需要的。
You can also serialize to a bytes object in memory. >>> shell 1 >>> b = pickle.dumps(entry) ① >>> type(b) ② <class 'bytes'> >>> entry3 = pickle.loads(b) ③ >>> entry3 == entry ④ TrueThe pickle.dumps() function (note the 's' at the end of the function name) ...
