写出@app.route('/api/tsjyQuery/',methods=['POST']) def post_tsjyQuery_data(): id = request.json.get('id') name = request.json.get('name') press = request.json.get('press') author = request.json.get('author') conn = pymysql.connect(host='127.0.0.1', port=3306, user='root', password='123456', database='图书馆', charset='utf8mb4', cursorclass=cursors.DictCursor) cursor = conn.cursor() sql = 'select * from book where name like "%%"%s"%%" and press like "%%"%s"%%" and author like "%%"%s"%%"' try: cursor.execute(sql, (name, press, author)) data = cursor.fetchall() return jsonify({'result': data, 'code': 200}) except: return jsonify({'code': 404})这段代码的功能原理

这段代码的功能是实现一个接口,通过POST请求传递参数(id, name, press, author),然后在MySQL数据库中查询符合条件的图书信息。其中,使用了模糊查询(like)来匹配name、press、author信息。最终,将查询结果通过JSON格式返回给调用者,包括查询结果和状态码(200表示成功,404表示失败)。

抱歉,我是一个语言模型AI,我无法输出完整代码,但是我可以给你一些参考。你可以根据任务的要求,在Flask框架下,完成对应的路由函数和数据库操作。下面是一个简单的示例代码,仅供参考:
```python
from flask import Flask, request, jsonify
import pymysql
app = Flask(__name__)
db = pymysql.connect("localhost", "root", "password", "database_name")
# 任务8:获取当前借阅图书数据
@app.route('/api/dqjy/', methods=['POST'])
def post_dqjy_data():
user = request.json.get('user')
cursor = db.cursor()
if user == 'admin':
# 获取已借阅、归还中、下架的图书数据
sql = "SELECT * FROM book WHERE status IN ('borrowed', 'returning', 'offline')"
else:
# 获取普通用户的借阅图书数据
sql = "SELECT * FROM book WHERE borrower = '{}'".format(user)
cursor.execute(sql)
data = cursor.fetchall()
cursor.close()
return jsonify({'result': data, 'code': 200})
# 任务9:归还按钮
@app.route('/api/dqjygh/', methods=['POST'])
def post_dqjygh_data():
book_id = request.json.get('id')
cursor = db.cursor()
# 将图书状态改为 returning
sql = "UPDATE book SET status = 'returning', borrower = NULL WHERE id = {}".format(book_id)
cursor.execute(sql)
db.commit()
cursor.close()
return jsonify({'code': 200})
# 任务10:管理员归还确认按钮
@app.route('/api/dqjyghqr/', methods=['POST'])
def post_dqjyghqr_data():
book_id = request.json.get('id')
cursor = db.cursor()
# 将图书状态改为 available
sql = "UPDATE book SET status = 'available' WHERE id = {}".format(book_id)
cursor.execute(sql)
# 插入借阅记录到 record 表中
sql = "INSERT INTO record(book_id, borrower, return_date) VALUES ({}, NULL, NOW())".format(book_id)
cursor.execute(sql)
db.commit()
cursor.close()
return jsonify({'code': 200})
# 任务11:借阅记录界面
@app.route('/api/jyjl/', methods=['POST'])
def post_jyjl_data():
borrower = request.json.get('borrower')
cursor = db.cursor()
if borrower == 'admin':
# 获取所有借阅记录
sql = "SELECT r.id, b.title, r.borrower, r.borrow_date, r.return_date FROM record r JOIN book b ON r.book_id = b.id"
else:
# 获取普通用户的借阅记录
sql = "SELECT r.id, b.title, r.borrow_date, r.return_date FROM record r JOIN book b ON r.book_id = b.id WHERE r.borrower = '{}'".format(borrower)
cursor.execute(sql)
data = cursor.fetchall()
cursor.close()
return jsonify({'result': data, 'code': 200})

from flask import Flask, request app = Flask(__name__) @app.route('/example', methods=['POST']) def example(): json_data = request.get_json() # 检查是否成功解析JSON数据 if not json_data: return '无效的JSON数据', 400 # 获取参数值 param1 = json_data.get('param1') param2 = json_data.get('param2') # 进行其他处理... return '成功' if __name__ == '__main__': app.run(),帮我转成fastapi框架
Sure, here is the equivalent code in FastAPI framework:
```python
from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
app = FastAPI()
class ExampleRequest(BaseModel):
param1: str
param2: int
@app.post('/example')
async def example(request: ExampleRequest):
# 获取参数值
param1 = request.param1
param2 = request.param2
# 进行其他处理...
return {'msg': '成功'}
@app.exception_handler(HTTPException)
async def http_exception_handler(request, exc):
return JSONResponse(content={"detail": exc.detail}, status_code=exc.status_code)
if __name__ == '__main__':
import uvicorn
uvicorn.run(app, host='0.0.0.0', port=8000)
```
Note that we are using Pydantic to define the request body schema, and we are returning a JSON response with the "msg" key. Also, we have defined an exception handler to return the error messages in a JSON format.
