java/php/node.js/python图书借阅管理系统【2024年毕设】

由于提供一个完整的图书借阅管理系统超出了问答的字数限制，以下是一个简化版本的图书借阅管理系统的核心功能代码示例，分别用Java、PHP、Node.js和Python语言提供。

Java示例（使用Spring Boot框架）:

@RestController
@RequestMapping("/books")
public class BookController {
 
    @Autowired
    private BookService bookService;
 
    @GetMapping("/borrow")
    public ResponseEntity<?> borrowBook(@RequestParam String bookId, @RequestParam String userId) {
        bookService.borrowBook(bookId, userId);
        return ResponseEntity.ok().body("Book borrowed successfully.");
    }
 
    @GetMapping("/return")
    public ResponseEntity<?> returnBook(@RequestParam String bookId, @RequestParam String userId) {
        bookService.returnBook(bookId, userId);
        return ResponseEntity.ok().body("Book returned successfully.");
    }
}

PHP示例:

<?php
class BookController extends Controller {
    public function borrowBook($bookId, $userId) {
        // 逻辑处理
        echo "Book borrowed successfully.";
    }
 
    public function returnBook($bookId, $userId) {
        // 逻辑处理
        echo "Book returned successfully.";
    }
}
?>

Node.js示例 (使用Express框架):

const express = require('express');
const router = express.Router();
 
router.get('/books/borrow', (req, res) => {
    const { bookId, userId } = req.query;
    // 逻辑处理
    res.send("Book borrowed successfully.");
});
 
router.get('/books/return', (req, res) => {
    const { bookId, userId } = req.query;
    // 逻辑处理
    res.send("Book returned successfully.");
});
 
module.exports = router;

Python示例 (使用Flask框架):

from flask import Flask, request
 
app = Flask(__name__)
 
@app.route('/books/borrow')
def borrow_book():
    book_id = request.args.get('bookId')
    user_id = request.args.get('userId')
    # 逻辑处理
    return "Book borrowed successfully.", 200
 
@app.route('/books/return')
def return_book():
    book_id = request.args.get('bookId')
    user_id = request.args.get('userId')
    # 逻辑处理
    return "Book returned successfully.", 200
 
if __name__ == '__main__':
    app.run()

这些示例代码提供了借阅和归还图书的核心功能，并且简化了逻辑处理部分，仅提供响应消息。在实际应用中，需要完善数据库操作、用户验证、异常处理等功能。
