两行Python代码将JSON文本转换成标准字典

在获取网页报文时，经常遇到JSON格式的文本。如：

```html

{"code":200,"message":"success","data":

 {"count":47,"pageCount":3,"floorCount":27,"list":

     \[

         {"info":

                 {"commentId":15302301,"articleId":113663811,"parentId":0,"postTime":"2021-03-07 19:21:17","content":"恭喜你","userName":"ria4com","digg":0,"diggArr":\[\],"parentUserName":null,"parentNickName":null,"avatar":"https://profile.csdnimg.cn/B/2/3/3\_ria4com","nickName":"低代码游戏开发","dateFormat":"1 小时前","tag":"","parentTag":null,"years":null,"vip":null,"vipIcon":null,"companyBlog":null,"companyBlogIcon":null,"flag":null,"flagIcon":null,"levelIcon":null},

          "sub":\[\],

          "pointCommentId":null

         }

     \]

 }

}

```

可以看到这个数据是比较复杂的，但整体就是一个符合JSON格式要求的文本。

针对该报文需要进行数据分析时，如果将其转换成标准字典类型，则数据访问代码好实现，可以利用Python的内置JSON模块将上述文本转换成了字典类型，再进行数据解析，真的好用。

```python

>>> import json

>>> text = """{"code":200,"message":"success","data":

 {"count":47,"pageCount":3,"floorCount":27,"list":

     \[

         {"info":

                 {"commentId":15302301,"articleId":113663811,"parentId":0,"postTime":"2021-03-07 19:21:17","content":"恭喜你","userName":"ria4com","digg":0,"diggArr":\[\],"parentUserName":null,"parentNickName":null,"avatar":"https://profile.csdnimg.cn/B/2/3/3\_ria4com","nickName":"低代码游戏开发","dateFormat":"1 小时前","tag":"","parentTag":null,"years":null,"vip":null,"vipIcon":null,"companyBlog":null,"companyBlogIcon":null,"flag":null,"flagIcon":null,"levelIcon":null},

          "sub":\[\],

          "pointCommentId":null

         }

     \]

 }

}"""

>>> response = json.loads(text)

>>> print(response['code'],response['data']['count'],response['data']['list'][0]['info']['nickName'],response['data']['list'][0]['info']['content'])

200 47 低代码游戏开发恭喜你

>>>

```

可以看到，上面案例中，将JSON文本转换成Python字典对象只需要import函数loads，再使用loads执行反序列化即可，用2行代码完成了JSON文本到字典类型的转换。
