@ChatGPT 剧情一丈夫被怀疑杀害了自己失踪的妻子被告上法庭，法庭上所有证据均不足以证明妻子是他杀害的，在最后一刻，原告律师用了一个招术：“将要请出最后一名证人——那就是受害者本人！ ”于是现场人员连同法官都不约而同朝向法庭证人入口处，只有丈夫一人未看，律师以此判定凶手就是被告本人，丈夫已深知妻子被自己杀害。是哪部电影？

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.

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()
