前言

jmespath在取值的时候，遇到一些特殊的字符处理起来会比较麻烦。
httprunner3.x提取和校验结果都是用jmespath取值，本篇总结几个常见的问题

使用案例

访问/api/test/demo接口，接口返回如下

{
    "code":0,
    "msg":"成功success!",
    "data":[
        {
            "age":20,
            "create_time":"2019-09-15",
            "id":1,
            "mail":"283340479@qq.com",
            "name":"yoyo",
            "sex":"M"
        },
        {
            "age":21,
            "create_time":"2019-09-16",
            "id":2,
            "mail":"123445@qq.com",
            "name":"yoyo111",
            "sex":"M"
        }
    ]
}

validate 校验

需求：
1.提取data数据中name的值为yoyo的邮箱，并校验结果是：283340479@qq.com
2.提取data数据组中，年龄大于20的结果，并校验结果的数量是：1

先看第一个问题，有[]字符的时候

config:
    name: logincase
    base_url: http://127.0.0.1:8000
    variables: {}
teststeps:
-
    name: step1 login
    request:
        url: /api/test/demo
        method: GET
    validate:
        - eq: [status_code, 200]
        - eq: [body.data[?name=='yoyo'].mail, ["283340479@qq.com"]]

运行后结果 ：expected ',' or ']', but got '['
