• HttpRunner3源码阅读:2. 模型定义


    models.py

    昨天体验的时候我们分别执行了httprunner -h,httprunner startproject demo, httprunner run demo,但是源码中其调用了其他文件中的方法所以暂时先不分析cli.py了,先从根本开始models.py

    可用资料

    typing[类型提示]: https://docs.python.org/zh-cn/3/library/typing.html
    pydantic[类型校验]: https://pydantic-docs.helpmanual.io/
    用上这两个库就有点强类型语言的味儿了
    泛型: https://docs.python.org/zh-cn/3/library/typing.html#generics
    枚举: https://docs.python.org/zh-cn/3/library/enum.html

    导包分析

    import os   # 系统包
    from enum import Enum   # 枚举类
    from typing import Any  # Any 表示 任意类型
    from typing import Dict # dict 的泛型版本。
    from typing import Text # Text 是 str 的别名
    from typing import Union # 联合类型;Union[X, Y] 的意思是,非 X 即 Y
    from typing import Callable # 可调类型; Callable[[int], str] 是把(int)转为 str 的函数。
    from typing import List # list 的泛型版本。
    from pydantic import BaseModel  # pydantic定义对象的基类
    from pydantic import Field    # pydantic 中 字段扩展定义
    from pydantic import HttpUrl  # 校验url地址的
    

    类型别名定义

    该系列中个人对类型的看法/叫法如下

    1. Text => str / 文本
    2. List => list / 列表
    3. Dict => dict / 字典
    Name = Text     # Name 的本质 其实就是 Text(Text 本质又是 str)
    Url = Text
    BaseUrl = Union[HttpUrl, Text]  # 是url 或者 Text 两者之一
    VariablesMapping = Dict[Text, Any] # key 是 Text ,value 是任意类型
    FunctionsMapping = Dict[Text, Callable] # key 是 Text, value是可调用对象
    Headers = Dict[Text, Text]  # key 是 str, value 也是 str
    Cookies = Dict[Text, Text] # 同上
    Verify = bool   # 布尔类型
    Hooks = List[Union[Text, Dict[Text, Text]]] # 列表,列表中的元素是 str 或者 key,value 都是 str
    Export = List[Text]  # 列表,列表中元素是 str
    Validators = List[Dict] # 列表,列表中元素是 字典
    Env = Dict[Text, Any]  # 字典 key 是 str, value 是任意类型
    

    请求方法

    # 枚举类,其中属性是 Text类型
    class MethodEnum(Text, Enum):
        GET = "GET"
        POST = "POST"
        PUT = "PUT"
        DELETE = "DELETE"
        HEAD = "HEAD"
        OPTIONS = "OPTIONS"
        PATCH = "PATCH"
    

    其余模型
