引言 **jsonpath在目前的工作中，主要用于『接口测试』中的字段提取。jsonpath通过『模糊查询

1.安装

pip install jsonpath

2.使用说明

1.语法

• jsonpath(数据源,’$..需提取的字段’)
• 返回list类型数据

2.示例

【题目】搜索“name=Allen”的相关信息

from jsonpath import jsonpath
jsonData = {"users": [
    {
        "id": 12,
        "name": "bosh",
        "No.": 1
    },
    {
        "name": "Allen",
        "No.": 34,
        "id": 13
    }
]}
def hello1():
    search_name = 'Allen'
    res = jsonpath(jsonData, f"$..users[?(@.name=='{search_name}')]")  # 提起name='Allen'的相关信息【返回list】
    print("Allen的相关信息：\t", res)
    # list转为dict
    resData = dict(res[0])
    print("dict数据:\t", resData)
    # 获取id
    id = resData.get('id')
    print("id=", id)
if __name__ == '__main__':
    hello1()

3.进阶

【题目】取type字段的第一个值
