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"
