4.1 开发环境搭建
4.2 数据库表结构实现
4.3 小程序界面实现
前端页面代码:
微信乐曲播放器
{{item.title}}
{{item.artist}}
/* pages/index/index.wxss */
.container {
padding: 20rpx;
}
.header {
font-size: 24rpx;
font-weight: bold;
margin-bottom: 20rpx;
}
.song-list {
display: flex;
flex-wrap: wrap;
}
.song-item {
width: calc(33.33% - 20rpx);
margin-right: 20rpx;
margin-bottom: 20rpx;
}
.cover {
width: 100%;
height: 150rpx;
}
.info {
padding: 10rpx;
}
.title {
font-size: 16rpx;
font-weight: bold;
}
.artist {
font-size: 14rpx;
color: #666;
}
// pages/index/index.js
Page({
data: {
songList: [
{ songId: 1, title: 'Song 1', artist: 'Artist 1', coverUrl: 'path/to/cover1.jpg' },
{ songId: 2, title: 'Song 2', artist: 'Artist 2', coverUrl: 'path/to/cover2.jpg' },
// Add more songs as needed
],
},
playSong: function (event) {
const songId = event.currentTarget.dataset.songid;
// Navigate to the song detail page or implement the play logic
wx.navigateTo({
url: '/pages/song/detail?songId=' + songId,
});
},
});
// pages/song/detail.js
Page({
data: {
song: {},
},
onLoad: function (options) {
const songId = options.songId;
// Fetch song details from the server or other data source
this.setData({
song: {
songId: songId,
title: 'Song ' + songId,
artist: 'Artist ' + songId,
coverUrl: 'path/to/cover' + songId + '.jpg',
filePath: 'path/to/song' + songId + '.mp3',
// Add more song details as needed
},
});
},
});
4.4 后端业务逻辑实现
后端模块部分代码:
// User.java
public class User {
private int userId;
private String openId;
private String nickname;
private String avatarUrl;
// Add other user-related fields as needed
// Getters and setters
}
// Song.java
public class Song {
private int songId;
private String title;
private String artist;
private String album;
private String genre;
private String filePath;
// Add other song-related fields as needed
// Getters and setters
}
// UserFavorite.java
public class UserFavorite {
private int favoriteId;
private User user;
private Song song;
// Getters and setters
}
// PlayRecord.java
public class PlayRecord {
private int recordId;
private User user;
private Song song;
private Timestamp playTime;
// Getters and setters
}
// UserService.java
public interface UserService {
User getUserById(int userId);
User getUserByOpenId(String openId);
void addUser(User user);
void updateUser(User user);
void deleteUser(int userId);
// Other methods as needed
}
// SongService.java
public interface SongService {
Song getSongById(int songId);
List getAllSongs();
void addSong(Song song);
void updateSong(Song song);
void deleteSong(int songId);
// Other methods as needed
}
// UserFavoriteService.java
public interface UserFavoriteService {
List getUserFavorites(int userId);
void addFavorite(UserFavorite favorite);
void removeFavorite(int favoriteId);
// Other methods as needed
}
// PlayRecordService.java
public interface PlayRecordService {
List getUserPlayRecords(int userId);
void addPlayRecord(PlayRecord playRecord);
// Other methods as needed
}
// UserController.java
@RestController
@RequestMapping("/api/user")
public class UserController {
// Inject UserService and handle HTTP requests
}
// SongController.java
@RestController
@RequestMapping("/api/song")
public class SongController {
// Inject SongService and handle HTTP requests
}
// UserFavoriteController.java
@RestController
@RequestMapping("/api/favorite")
public class UserFavoriteController {
// Inject UserFavoriteService and hanle HTTP requests
}
// PlayRecordController.java
@RestController
@RequestMapping("/api/playrecord")
public class PlayRecordController {
// Inject PlayRecordService and handle HTP requests
}
