如何去除JSON中的count、next等属性，仅保留results数组数据？

以下是几种不同场景下的实现方式：

Python 环境 #

直接利用Python内置的json模块解析数据，提取目标字段即可：

import json

# 原始JSON数据（可替换为从文件/接口读取的内容）
raw_json = '''{"count":3,"next":null,"previous":null,"results":[{"name":"Max","slug":"DrMax","directions":["Surgery","Stomach"],"description":"Surgery","work_experience":"2","birt_date":"2018-12-04"},{"name":"Ban","slug":"0","directions":["X-Ray"],"description":"Xray","work_experience":"6","birt_date":"2022-11-02"},{"name":"qwe","slug":"qwe","directions":["Surgery","X-Ray","Stomach"],"description":"Xray","work_experience":"6","birt_date":"2022-11-14"}]}'''

# 解析JSON字符串
parsed_data = json.loads(raw_json)
# 提取results数组
results_array = parsed_data["results"]
# 输出格式化后的JSON
print(json.dumps(results_array, indent=2))

命令行（jq工具） #

如果是在终端处理JSON文件或字符串，使用jq工具可以快速提取字段：

# 直接处理字符串
echo '{"count":3,"next":null,"previous":null,"results":[{"name":"Max","slug":"DrMax","directions":["Surgery","Stomach"],"description":"Surgery","work_experience":"2","birt_date":"2018-12-04"},{"name":"Ban","slug":"0","directions":["X-Ray"],"description":"Xray","work_experience":"6","birt_date":"2022-11-02"},{"name":"qwe","slug":"qwe","directions":["Surgery","X-Ray","Stomach"],"description":"Xray","work_experience":"6","birt_date":"2022-11-14"}]}' | jq '.results'

# 处理文件的话，假设文件名为data.json
jq '.results' data.json

JavaScript/Node.js 环境 #

在前端或Node.js中，用原生JSON API解析提取：

// 原始JSON数据
const rawJson = '{"count":3,"next":null,"previous":null,"results":[{"name":"Max","slug":"DrMax","directions":["Surgery","Stomach"],"description":"Surgery","work_experience":"2","birt_date":"2018-12-04"},{"name":"Ban","slug":"0","directions":["X-Ray"],"description":"Xray","work_experience":"6","birt_date":"2022-11-02"},{"name":"qwe","slug":"qwe","directions":["Surgery","X-Ray","Stomach"],"description":"Xray","work_experience":"6","birt_date":"2022-11-14"}]}';

// 解析JSON
const data = JSON.parse(rawJson);
// 获取results数组
const results = data.results;
// 输出结果
console.log(JSON.stringify(results, null, 2));
