node.js图书借阅与归还

// 1. 使用Node.js编写图书借阅与归还的后端接口
// 借阅接口
app.post('/borrowBook', (req, res) => {
  const { bookId, userId, borrowTime } = req.body;
  // 执行借阅操作的代码逻辑
  res.send('Book borrowed successfully');
});

// 归还接口
app.post('/returnBook', (req, res) => {
  const { borrowId, returnTime } = req.body;
  // 执行归还操作的代码逻辑
  res.send('Book returned successfully');
});

// 2. 使用Vue和Express结合实现前后端交互
// Vue前端代码示例
methods: {
  borrowBook() {
    this.$axios.post('/borrowBook', { bookId: this.bookId, userId: this.userId, borrowTime: new Date() })
      .then(response => {
        console.log(response.data);
      });
  },
  returnBook() {
    this.$axios.post('/returnBook', { borrowId: this.borrowId, returnTime: new Date() })
      .then(response => {
        console.log(response.data);
      });
  }
}

// Express后端代码示例
app.post('/borrowBook', (req, res) => {
  const { bookId, userId, borrowTime } = req.body;
  // 执行借阅操作的代码逻辑
  res.send('Book borrowed successfully');
});

app.post('/returnBook', (req, res) => {
  const { borrowId, returnTime } = req.body;
  // 执行归还操作的代码逻辑
  res.send('Book returned successfully');
});
