之前已经实现了，这次来实现了Json的序列化。

    测试代码和结果如下：

import Json.JsonToolclass Score:    math = 0    chinese = 0class Book:    name = ''    type = ''class Student:    id = ''    name = ''    score = Score()    books = [Book()]student = Student()json_data = '{"id":"123", "name":"kid", "score":{"math":100, "chinese":98}, ' \            '"books":[{"name":"math", "type":"study"}, ' \            '{"name":"The Little Prince", "type":"literature"}]} 'Json.JsonTool.json_deserialize(json_data, student)print(student.name)print(student.score.math)print(student.books[1].name)student_str = Json.JsonTool.json_serialize(student)print(student_str)input("\n按回车键退出。")

运行结果：

kid100The Little Prince{
    "books": [{
   "name": "math", "type": "study"}, {
   "name": "The Little Prince", "type": "literature"}], "id": "123", "name": "kid", "score": {
   "chinese": 98, "math": 100}}按回车键退出。

 

    实现代码如下：

def json_serialize(obj):    obj_dic = class2dic(obj)    return json.dumps(obj_dic)def class2dic(obj):    obj_dic = obj.__dict__    for key in obj_dic.keys():        value = obj_dic[key]        obj_dic[key] = value2py_data(value)    return obj_dicdef value2py_data(value):    if str(type(value)).__contains__('.'):        # value 为自定义类        value = class2dic(value)    elif str(type(value)) == "
     
      ":        # value 为列表        for index in range(0, value.__len__()):            value[index] = value2py_data(value[index])    return value
