在app/parameter/demo\_param.py文件中，我们首先导入必要的模块。接着，定义了一个名为DemoParam的Pydantic模型，它继承自BaseModel。这个模型对应于请求体中的参数，包含user\_name（字符串类型）、age（整数类型）和city（字符串或None类型）三个字段。通过这个模型，我们可以更清晰地定义和验证请求中的数据。在app...
注意其他的类Path也有此功能。 第一类:Query用作默认参数,可设置为None或者其他值 **# 步骤1:从fastapi导入Query** from fastapi import FastAPI, Query from typing import Optional app = FastAPI() @app.get('/items/') async def read_items(**q: Optional[str] = Query(None, max_length=50, min_...
In this case, the function parameter q will be optional, and will be None by default.Check Also notice that FastAPI is smart enough to notice that the path parameter item_id is a path parameter and q is not, so, it's a query parameter....
输入命令 uvicorn path_parameter:path_para_api --reload 即可启动测试服务端,之后打开浏览器键入http://127.0.0.1:8000/read/3即可看到如下图的返回,此时说明3已经成功被服务端解包并返回。 二、查询参数 由上例可知,当我们在请求路径中加入变量并且在对应方法中接收同名参数,FastAPI即可认为是路径参数。那么当我们...
