模拟一个在线音乐播放程序
# 1, 使用C/S架构来进行设计,分别写出客户端和服务器程序
# 2,客户端链接服务器之后,服务器向用户提示可以选择的歌曲列表,用户选择后开始播放(音频文件存放在本地即可)
#思路是通过socketserver ,客户端发送指令到服务端,服务端连接数据库查到歌曲名字路径返回给客户端,客户端通过pygame模块查找到歌曲路径 播放歌曲
#创建数据表,插入歌曲名字和路径
CREATE TABLE t_music(
id INT PRIMARY KEY AUTO_INCREMENT,
NAME VARCHAR(32),
path VARCHAR(32)
)
SELECT * FROM t_music
INSERT INTO t_music(NAME,path) VALUE("味道","D:\\老男孩\\味道.mp3"),("世间美好与你环环相扣","D:\\老男孩\\世间美好与你环环相扣.mp3")
