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。
