嘿，大家好！今天我們要聊的是如何在校園里搭建一個(gè)校友管理系統(tǒng)。這個(gè)系統(tǒng)可以幫助學(xué)校更好地管理和聯(lián)系校友們，促進(jìn)校友與學(xué)校的互動(dòng)。接下來(lái)，我會(huì)分享一些具體的代碼和技術(shù)細(xì)節(jié)，讓大家對(duì)整個(gè)過(guò)程有個(gè)清晰的認(rèn)識(shí)。

一、數(shù)據(jù)庫(kù)設(shè)計(jì)

首先，我們需要設(shè)計(jì)數(shù)據(jù)庫(kù)來(lái)存儲(chǔ)校友的信息。我們可以使用MySQL來(lái)創(chuàng)建數(shù)據(jù)庫(kù)和表。比如：

CREATE DATABASE alumni_system;
USE alumni_system;

CREATE TABLE alumni (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    email VARCHAR(100) UNIQUE NOT NULL,
    graduation_year YEAR,
    phone VARCHAR(20)
);

融合門戶

二、后端開(kāi)發(fā)

接下來(lái)是后端開(kāi)發(fā)，這里我們選擇Node.js和Express框架。我們將創(chuàng)建API接口來(lái)處理數(shù)據(jù)請(qǐng)求。例如，添加新的校友信息：

const express = require('express');
const mysql = require('mysql');

const app = express();
app.use(express.json());

const db = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: 'password',
    database: 'alumni_system'
});

db.connect();

app.post('/api/alumni', (req, res) => {
    const { name, email, graduation_year, phone } = req.body;
    const sql = 'INSERT INTO alumni SET ?';
    db.query(sql, { name, email, graduation_year, phone }, (err, result) => {
        if (err) throw err;
        res.send('Alumni added successfully!');
    });
});

app.listen(3000, () => console.log('Server running on port 3000'));

三、前端展示

最后，我們使用React來(lái)構(gòu)建前端界面。用戶可以在這里查看和添加校友信息。這里是一個(gè)簡(jiǎn)單的例子：

<script src="https://unpkg.com/react@17/umd/react.development.js"></script>
<script src="https://unpkg.com/react-dom@17/umd/react-dom.development.js"></script>
<script src="https://unpkg.com/babel-standalone@6/babel.min.js"></script>

<div id="root"></div>

<script type="text/babel">
    class AlumniForm extends React.Component {
        constructor(props) {
            super(props);
            this.state = {
                name: '',
                email: '',
                graduation_year: '',
                phone: ''
            };
        }

        handleChange = (e) => {
            this.setState({ [e.target.name]: e.target.value });
        };

        handleSubmit = (e) => {
            e.preventDefault();
            fetch('http://localhost:3000/api/alumni', {
                method: 'POST',
                headers: { 'Content-Type': 'application/json' },
                body: JSON.stringify(this.state)
            })
            .then(res => res.text())
            .then(console.log);
        };

        render() {
            return (
                <form onSubmit={this.handleSubmit}>
                    <input type="text" name="name" onChange={this.handleChange} placeholder="Name" />
                    <input type="email" name="email" onChange={this.handleChange} placeholder="Email" />
                    <input type="number" name="graduation_year" onChange={this.handleChange} placeholder="Graduation Year" />
                    <input type="tel" name="phone" onChange={this.handleChange} placeholder="Phone" />
                    <button type="submit">Submit</button>
                </form>
            );
        }
    }

    ReactDOM.render(<AlumniForm />, document.getElementById('root'));
</script>

好了，這就是整個(gè)校友管理系統(tǒng)的基本實(shí)現(xiàn)流程。希望這些代碼和技巧能幫到你！
