【HttpRunner】学习准备

1、安装python 3.7及以上版本：

2、安装fastapi：pip install fastapi[all]

3、把如下代码粘贴复制到main.py文件中：

from fastapi import FastAPI
from typing import Union
from pydantic import BaseModel
app = FastAPI()

class Item(BaseModel):
    name: str
    description: Union[str, None] = None
    price: float
    tax: Union[float, None] = None



@app.get("/")
async def root():
    return {"message": "Test HttpRunner Demo"}


@app.get("/items/{item_id}")
async def read_item(item_id: str, q: Union[str, None] = None, short: bool = False):
    item = {"item_id": item_id}
    if q:
        item.update({"q": q})
    if not short:
        item.update(
            {"description": "This is an amazing item that has a long description"}
        )
    return item


@app.get("/users/{user_id}/items/{item_id}")
async def read_user_item(
    user_id: int, item_id: str, q: Union[str, None] = None, short: bool = False
):
    item = {"item_id": item_id, "owner_id": user_id}
    if q:
        item.update({"q": q})
    if not short:
        item.update(
            {"description": "This is an amazing item that has a long description"}
        )
    return item


@app.post("/additems/")
async def create_item(item: Item):
    return item


@app.put("/items/{item_id}")
def update_item(item_id: int, item: Item):
    return {"item_name": item.name, "item_id": item_id}

4、进入main.py所在目录执行命令：uvicorn main:app --reload
