Use WebMan technology to build a professional music playing platform
Title: Using WebMan technology to build a professional music playback platform
Foreword:
With the rapid development of the Internet, music has become indispensable in people's lives part. Therefore, building a professional music playback platform has become particularly important. In this article, we will introduce how to use WebMan technology to build a powerful music playback platform, and attach corresponding code examples.
1. Technology Selection and Preparation
Before building a music playback platform, we need to choose the appropriate technology. Here, we choose to use WebMan technology because it is a very powerful and flexible technology that can help us quickly build a professional music playback platform.
Before we start, we need to prepare the following tools and environment:
- Web server (such as Apache, Nginx, etc.)
- PHP programming language
- MySQL database
- HTML, CSS and JavaScript technology
2. Database design
When building a music playback platform, the core data storage and management work is completed by the database. The following is a simple database design example:
-
Table: Users table (users)
Field:- id (user ID)
- username (username)
- password (password)
- email (email)
-
Table: song list (songs )
Field:- id (song ID)
- title (song title)
- artist (song artist)
- album ( The album the song belongs to)
- file_path (song file path)
-
Table: playlists (playlists)
Field:- id (playlist ID)
- user_id (user ID)
- name (playlist name)
-
Table: Playlist Songs (playlist_songs)
Field:- id (playlist song ID)
- playlist_id (playlist ID)
- song_id (song ID)
3. Build the user interface
Next, we will build a user-friendly front-end interface. In this example, we will use HTML, CSS and JavaScript to achieve this.
HTML code example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>音乐播放平台</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1 id="音乐播放平台">音乐播放平台</h1>
<div id="playlist">
<h2 id="我的播放列表">我的播放列表</h2>
<ul id="playlist-items">
<!-- 此处填充播放列表 -->
</ul>
</div>
<div id="songs">
<h2 id="歌曲列表">歌曲列表</h2>
<ul id="song-items">
<!-- 此处填充歌曲列表 -->
</ul>
</div>
<script src="script.js"></script>
</body>
</html>CSS code example (style.css):
/* 样式表示例 */
body {
font-family: Arial, sans-serif;
}
h1, h2 {
color: #333;
}
#playlist, #songs {
margin-bottom: 20px;
}
#playlist-items li, #song-items li {
cursor: pointer;
margin-bottom: 10px;
}JavaScript code example (script.js):
// JavaScript代码示例
document.addEventListener("DOMContentLoaded", function() {
// 获取并填充播放列表
var playlistItems = document.getElementById("playlist-items");
// TODO: 通过Ajax请求获取播放列表数据并填充
// 获取并填充歌曲列表
var songItems = document.getElementById("song-items");
// TODO: 通过Ajax请求获取歌曲列表数据并填充
// 添加点击事件监听器
playlistItems.addEventListener("click", function(e) {
// TODO: 根据所点击的播放列表项来切换歌曲播放
});
songItems.addEventListener("click", function(e) {
// TODO: 根据所点击的歌曲项来添加到当前播放列表
});
});four ,Building back-end logic
Through the PHP programming language and MySQL database, we can build the back-end logic. The following is a simple PHP code example:
<?php
// 数据库连接配置
$host = "localhost";
$username = "root";
$password = "password";
$dbname = "music_platform";
$conn = new mysqli($host, $username, $password, $dbname);
if ($conn->connect_error) {
die("数据库连接失败：" . $conn->connect_error);
}
// 获取播放列表数据
$playlists = [];
$sql = "SELECT id, name FROM playlists";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$playlists[] = $row;
}
}
// 获取歌曲列表数据
$songs = [];
$sql = "SELECT id, title, artist, album, file_path FROM songs";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$songs[] = $row;
}
}
// 返回数据
$data = [
'playlists' => $playlists,
'songs' => $songs
];
header('Content-Type: application/json');
echo json_encode($data);
?> 5. Summary
By using WebMan technology, we can easily build a powerful music playback platform. In this article, we introduce the steps of technology selection and preparation, database design, user interface construction, and back-end logic construction, and provide relevant code examples. We hope that these examples can help readers better understand and use WebMan technology to build a professional music playback platform.
