这是一个用 Python 的 tkinter 库做的一个网络音乐播放器。我不说它的 UI 设计的有多好看，但是它的功能绝对是全站首个！坚持看到底，你不点赞算我输！

或者：
pip install -r requirements.txt
一、爬取音乐
下面的代码为 get.py 里的内容。
import requestssearch_url = '/api/www/search/searchMusicBykeyWord'search_headers = {'Referer': '/search/list?key=','Cookie': '_ga=GA1.2.12......','csrf': 'YO4OH2VYH1A'}search_params = {'key': 'str', # 查找关键字'pn': '1', # 页数'rn': '20', # 项数'httpsStatus': '1','reqId': '6e028fc0-db8f-11eb-b6f5-ff7d54a57f2b'}from_url = '/url'from_params = {'rid': '148526468', # 歌曲 rid'type': 'convert_url3','br': '128kmp3',}lrc_url = '/newh5/singles/songinfoandlrc?musicId={rid}'headers = {'user-agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.114 Safari/537.36 Edg/91.0.864.59'}class Kuwo:def search_kuwo(self, kw):#search_params.update({'key': kw})response = requests.get(search_url,params=search_params,headers={**headers, **search_headers},timeout=2,).json()datas = response.get('data', {}).get('list', {})result = [[r.get('name', ''),r.get('artist', ''),r.get('album', ''),r.get('songTimeMinutes', ''),r.get('pic', ''),r.get('pic120', ''),r.get('rid', '')]for r in datas]return resultdef get_music_url(self, rid):#from_params['rid'] = ridurl = requests.get(from_url, params=from_params, headers=headers, timeout=2).json()['url']return urldef get_music_content(self, rid):url = self.get_music_url(rid)content = requests.get(url, headers=headers, timeout=2).contentreturn contentdef get_music_lrc(self, rid):lrc_data = requests.get(lrc_url.format(rid=rid), headers=headers, timeout=2).json()lrc_list = lrc_data.get('data', {}).get('lrclist', [{1: '无歌词', 2: '0'}])lrc = [list(l.values()) for l in lrc_list]return lrcdef get_pic(self, url):pic = requests.get(url, headers=headers).contentreturn pic
二、歌词操作
下面代码为 lrc.py 里的代码。
import reclass Lrc:def __init__(self):self.LRC = [[0.0, '无歌词']]self.Times = [0.0]self.Words = ['无歌词']def decode_from_str(self, lrc: str):lrc = lrc.strip('\n')res1 = self.SP_DTWDSTR.findall(lrc)res2 = list()res3 = dict()result = dict()for r in res1:res2.append([self.SP_DTSTR.findall(r[0]), r[1]])for r in res2:for t in r[0]:res3[self.tosec(t)] = r[1]result = sorted(list(res3.items()), key=lambda x: x[0])self.decode(result)return self.LRCdef decode(self, lrcs):self.LRC = lrcsr = list(zip(*lrcs))self.Words = list(r[0])self.Times = list(map(self.tosec, list(r[1])))# 将字符串时间变为秒def tosec(self, t:str):res1 = t.split(':')[::-1]res2 = [float(r) * (60 ** i) for i, r in enumerate(res1)]result = sum(res2)return result# 根据浮点数播放进度获取对应歌词索引def get_index(self, t:float):times = [*self.Times, t]times.sort()return times.index(t) - 1
三、播放器
下面代码为 player.py 里的内容。
播放器的方法其实和 pygame.mixer.music 的方法差别不大。但要注意的是第 1~2 行代码是用于去除导入 pygame 模块时自动打印的信息。
from os import environenviron['PYGAME_HIDE_SUPPORT_PROMPT'] = '1'import pygamefrom io import BytesIOclass Player:def __init__(self):pygame.mixer.init()self.music = pygame.mixer.musicdef reset(self):self.music.stop()pygame.mixer.pre_init()def load(self, filename):self.music.load(filename)def play(self):self.music.play()def pause(self):self.music.pause()def unpause(self):self.music.unpause()def stop(self):self.music.stop()def get_length(self):return self.music.get_length()def get_pos(self):return self.music.get_pos()def set_pos(self, value=0):self.music.rewind()self.music.set_pos(value)def get_volume(self):return self.music.get_volume()def set_volume(self, value=0.5):return self.music.get_volume(value)def addsong(self, filename):self.music.quene(filename)
四、GUI 界面
下面代码为 gui.py 中的代码。
进度条查看、控制滚动歌词pygame 播放网络音乐

五、启动程序
下面代码为 main.pyw 中的代码。双击此文件可以直接运行。
import guiif __name__ == '__main__':gui.Window()
后记
这个音乐播放器还有一些不完善的地方，比如只能在有网络的情况下搜索，否则会报错；没有播放列表等等。
