json 文件处理

1. 读取：

然后通过 key 值访问：

with open('1.json','r',encoding='utf8') as f:
    json_data = json.load(f)
for json_dict in json_data:
    _id = json_dict['姓名']
    print("The id is {}".format(_id))
>>
[
  {"姓名": "张三","年龄": 25},
  {"姓名": "李四","年龄": 26}
]

• 如果有多行文件，上述读取会出错，修改为：
  这种针对的是 一行是一个 json{} 的数据情况：

{"text": "如何演好自己的角色，请读《演员自我修养》《喜剧之王》周星驰崛起于穷困潦倒之中的独门秘笈", "spo_list": [{"predicate": "主演", "object_type": "人物", "subject_type": "影视作品", "object": "周星驰", "subject": "喜剧之王"}]}
{"text": "茶树茶网蝽，Stephanitis chinensis Drake，属半翅目网蝽科冠网椿属的一种昆虫", "spo_list": [{"predicate": "目", "object_type": "目", "subject_type": "生物", "object": "半翅目", "subject": "茶树茶网蝽"}]}

import json
with open(r"D:\project\zhangyi\relation_extract\美亚数据\all_data.json", 'r',encoding='utf-8') as file:
    for line in file.readlines():
        js_l = json.loads(line)
        print(js_l)

1. json.dumps() 序列，中文出现 \u 编码

text = json.dumps(InputStr,ensure_ascii=False)
