hi
ervan is dat de schoonheid van je huid gedurende de dag toeneemt. In de ochtend heb je een frisse en stralende huid. In de avond ben je klaar om de nacht in te gaan met een gezonde en glanzende huid. De ingrediënten in deze crème helpen ook bij het verminderen van fijne lijntjes en rimpels, het verbeteren van de algemene teint en het verminderen van oneffenheden zoals acne en littekens. De crème is ook vrij van parabenen, sulfaten, phthalaten en kunstmatige kleur- en geurstoffen. Het is een goede keuze voor mensen met een gevoelige huid.

生成一个纯后端的API接口，用于学生信息管理，用FastAPI+mysql+sqlalchemy+pydantic+logging，用到yield db，要求项目结构中有Models目录，Routers目录，Schemas目录，Logs目录，Config目录，Tests目录，并给出每个文件详细的代码编写，
实现学生信息管理的全部功能
一、项目结构
Project ├───Models // ORM 模型 │ └───model.py ├───Routers // 路由 │ └───router.py ├───Schemas // 数据模型 │ └───schema.py ├───Logs // 日志 │ └───log.py ├───Config // 配置文件 │ └───config.py └───Tests // 测试 └───test.py二、模型文件（Models/model.py）
# 导入相关模块 from sqlalchemy import Column, Integer, String from sqlalchemy.ext.declarative import declarative_base # 创建基类 Base = declarative_base() # 创建学生表 class Student(Base): __tablename__ = 'student' # 创建表字段 id = Column(Integer, primary_key=True, autoincrement=True) name = Column(String(50), nullable=False) age = Column(Integer) gender = Column(String(10))三、路由文件（Routers/router.py）
# 导入相关模块 from typing import List from fastapi import APIRouter, Depends from sqlalchemy.orm import Session from sqlalchemy import create_engine from . import models, schemas # 创建路由 router = APIRouter() # 连接数据库 engine = create_engine('mysql+pymysql://root:123456@localhost:3306/student_info') # 获取session def get_db(): db = Session(bind=engine) try: yield db finally: db.close() # 获取所有学生信息 @router.get('/get_all_student', response_model=List[schemas.Student]) def get_all_student(db: Session=Depends(get_db)): students = db.query(models.Student).all() return students # 添加学生信息 @router.post('/add_student', response_model=schemas.Student) def add_student(student: schemas.Student, db: Session=Depends(get_db)): student_model = models.Student(name=student.name, age=student.age, gender=student.gender) db.add(student_model) db.commit() db.refresh(student_model) return student_model # 修改学生信息 @router.put('/update_student/{student_id}', response_model=schemas.Student) def update_student(student_id: int, student: schemas.Student, db: Session=Depends(get_db)): student_model = db.query(models.Student).filter(models.Student.id == student_id).first() student_model.name = student.name student_model.age = student.age student_model.gender = student.gender db.commit() db.refresh(student_model) return student_model # 删除学生信息 @router.delete('/delete_student/{student_id}', response_model=schemas.Student) def delete_student(student_id: int, db: Session=Depends(get_db)): student_model = db.query(models.Student).filter(models.Student.id == student_id).first() db.delete(student_model) db.commit() return student_model四、模型文件（Schemas/schema.py）
# 导入相关模块 from pydantic import BaseModel # 创建学生信息模型 class Student(BaseModel): name: str age: int gender: str五、日志文件（Logs/log.py）
# 导入相关模块 import logging # 设置日志等级、格式、文件名 logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', filename='logs/student_info.log')六、配置文件（Config/config.py）
# 数据库连接配置 DATABASE_CONFIG = { 'host': 'localhost', 'user': 'root', 'password': '123456', 'db': 'student_info' }七、测试文件（Tests/test.py）
# 导入相关模块 import json import unittest from fastapi.testclient import TestClient from routers import router # 测试类 class TestStudent(unittest.TestCase): # 测试初始化 def setUp(self): self.client = TestClient(router) # 测试获取所有学生信息 def test_get_all_student(self): response = self.client.get('/get_all_student') self.assertEqual(response.status_code, 200) # 测试添加学生信息 def test_add_student(self): data = { 'name': '张三', 'age': 18, 'gender': '男' } response = self.client.post('/add_student', data=json.dumps(data)) self.assertEqual(response.status_code, 200) # 测试修改学生信息 def test_update_student(self): data = { 'name': '李四', 'age': 18, 'gender': '男' } response = self.client.put('/update_student/1', data=json.dumps(data)) self.assertEqual(response.status_code, 200) # 测试删除学生信息 def test_delete_student(self): response = self.client.delete('/delete_student/2') self.assertEqual(response.status_code, 200) # 执行测试 if __name__ == '__main__': unittest.main() -
