Use chatgpt to generate FastApi addition, deletion, modification and query code
Fastapi additions, deletions, modifications and checks
FastAPI is a high-performance Python web framework, which can be used to easily implement addition, deletion, modification and query operations.
The following is an example to demonstrate how to use FastAPI to implement CRUD operations:
# 导入 FastAPI 相关模块和依赖项
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
# 定义一个数据模型
class User(BaseModel):
name: str
age: int
email: str
# 模拟数据库
database = []
# 添加用户数据
@app.post("/users/")
async def add_user(user: User):
user_dict = user.dict()
database.append(user_dict)
return user_dict
# 查询用户数据
@app.get("/users/")
async def get_users():
return database
# 查询单个用户数据
@app.get("/users/{user_id}")
async def get_user(user_id: int):
return database[user_id]
# 修改用户数据
@app.put("/users/{user_id}")
async def update_user(user_id: int, name: str, age: int, email: str):
database[user_id]["name"] = name
database[user_id]["age"] = age
database[user_id]["email"] = email
return database[user_id]
# 删除用户数据
@app.delete("/users/{user_id}")
async def delete_user(user_id: int):
database.pop(user_id)
return {"message": "User has been deleted!"}
In this example, we define a data model named User, simulating a simple user database. Then we realized the operation of adding, deleting, modifying and checking through different routes.
Among them, @app.postdecorators are used to add user data; @app.getdecorators are used to query all user data and individual user data; @app.putdecorators are used to modify user data; @app.deletedecorators are used to delete user data.
In addition to the methods in the above example, FastAPI also provides other asynchronous methods and asynchronous libraries, which can more easily implement addition, deletion, modification and query operations. This enables more efficient web development.
