逐层解析Python3自定义json-创新互联

这篇文章主要为大家逐层解析Python3自定义json，内容简而易懂，希望大家可以学习一下，学习完之后肯定会有收获的，下面让小编带大家一起来看看吧。

用python3对json内容逐层进行解析，拿中国天气网的接口返回数据测试，

代码如下：

# -*- coding: utf-8 -*-
import operator as op
from collections import defaultdict

class Json(object):

  def __init__(self, json: str):
    sth = eval(json)
    load = lambda sth: sth if op.eq(type(sth).__name__, dict.__name__) else None
    self.json_dict = load(sth)
    self.ret_j = defaultdict(dict)
    self.analyze(self.json_dict)

  def analyze(self, j_dict: dict, lvl=0) -> None:
    lvl += 1
    for k in j_dict:
      v = j_dict[k]
      v_type = type(v)
      try:
        self.ret_j[lvl][str(j_dict)].append(f"{k}:{v}")
      except:
        self.ret_j[lvl][str(j_dict)] = []
        self.ret_j[lvl][str(j_dict)].append(f"{k}:{v}")
      if op.eq(v_type.__name__, dict.__name__):
        self.analyze(v, lvl)
      elif op.eq(v_type.__name__, list.__name__):
        for each in v:
          if op.eq(type(each).__name__, dict.__name__):
            self.analyze(each, lvl)

  def get_analysis(self) -> None:
    print(f"这个json拢共分{len(self.ret_j)}层")
    print("------")
    for lvl in self.ret_j:
      print(f"第{lvl}层解析")
      for root in self.ret_j[lvl]:
        print(f"解析内容：{root}")
        for each in self.ret_j[lvl][root]:
          print(each)
      print("------")

if __name__ == '__main__':
  try:
    import requests
  except:
    exit(0)
  url = "http://forecast.weather.com.cn/napi/h6map/city/101/jQuery1533133004035?callback=jQuery1533133004035"
  r = requests.get(url)
  d_r = r.content.decode()
  json_4_test = d_r[d_r.index("(") + 1:d_r.index(")")]
  Json(json_4_test).get_analysis()
