json数据的处理和转化（loads/load/dump/dumps）

import json

}
response=requests.get(url)
content=response.content.decode()
print('content',type(content),content)

# json.loads把Json格式字符串解码转换成Python对象
# 将字符串转化成字典,编码会乱
a=json.loads(content)
print('json.loads',type(a),a)

# json.dumps:实现python类型转化为json字符串
# 将字典转成字符串才能进行保存,
a1=json.dumps(a,ensure_ascii=False)
print('json.dumps',type(a1),a1)

with open('static/douban.json','w',encoding='utf-8') as f:
    # f.write(a1)
    # json.dump将Python内置类型序列化为json对象后写入文件
    json.dump(a1,f,ensure_ascii=False)

with open('static/douban.json','r',encoding='utf-8') as r:
    r_dict=json.loads(r.read(),encoding='utf-8')
    print('r_dict',type(r_dict),r_dict)



with open('static/douban2.json','w',encoding='utf-8') as f:
    json.dump(r_dict,f,ensure_ascii=False)
    # json.dump(content, f, ensure_ascii=False)  # 会乱码？？？？

# json.load读取文件中json形式的字符串元素 转化成python类型
with open('static/douban2.json','r',encoding='utf-8') as r:
    load_dict=json.load(r)
    print('load_dict',type(load_dict),load_dict)

 运行结果如下：
