一起用python做个炫酷音乐播放器，想听啥随便搜
uQDIgQcZ4qBt2GcZMS_LrCeB/?source=tuwen_detail)
前言
首先我们还是一起来看看实现的音乐播放器最终效果如何：
由于之前已经介绍过了音乐播放器V1.0版本的大致功能，如果有不了解的小伙伴可以先去看看V1.0版本的音乐播放器大致介绍。【
python自制一款炫酷音乐播放器，想听啥随便搜！ 】下面我们就介绍这个音乐播放器V2.0版本新加的部分功能制作过程。
一、核心功能设计
在之前的V1.0版本中，我们已经完成了播放器UI界面的设计，对播放器的画面布局进行排版设计；其次音乐播放器的最重要的核心功能根据关键字搜索自动爬取音乐并且进行音乐播放已经完成了。当然也完成了一些播放器常见的附加功能，如播放方式列表循环、单曲循环、随机播放；当前上一首下一首播放；播放暂停开始；音量增加减少等。
V2.0版本中，我们主要增加了以下几个核心功能：
- 对UI排版布局增加子列表页面，主要包括最近播放、喜爱的歌、歌词显示、本地音乐播放4个子列表页面
- 音乐本地下载及添加我喜爱的歌曲功能
- 我喜爱的歌内容保存及初始化读取我喜爱的歌列表显示，喜爱歌曲列表播放功能
- 当前播放歌曲歌词读取显示功能
- 读取播放本地歌曲功能
二、实现步骤
1. UI排版布局
V2.0版本中我们将新增的几个子列表页面放在界面中间主体右侧，叠加在音乐搜索显示列表页。这里我们使用的还是 ** pyqt5 **
。添加子列表页面核心设计代码如下：
def init_ui(self):
self.main_layout.addWidget(self.up_widget, 0, 0, 1, 110)
self.main_layout.addWidget(self.left_widget, 1, 0, 90, 20)
self.main_layout.addWidget(self.right_widget, 1, 20, 90, 90) # 22右侧部件在第0行第3列，占8行9列
self.main_layout.addWidget(self.down_widget, 100, 0, 10, 110)
self.main_layout.addWidget(self.close_widget, 0, 105, 1, 5) # 左侧部件在第0行第0列，占1行3列
self.down_layout.addWidget(self.label, 1, 0, 1, 1)

pix = pix_img.scaled(100, 100, Qt.KeepAspectRatio)
self.label223.setPixmap(pix)
# self.label5.setMaximumSize(1,1)
self.tab3_layout.addWidget(self.label223, 0, 0, 1, 1)
self.button_1237 = QPushButton(icon('fa.play', color='#FFFFFF', font=24), "播放全部")
self.button_1237.clicked.connect(self.allplaylove)
self.button_1237.setStyleSheet(

self.tab3_layout.addWidget(self.button_1236, 0, 3, 1, 1)
self.listwidget3 = QListWidget(self.tab3)

self.tab4 = QWidget()
self.tab4.setObjectName("tab")
self.tab4_layout = QGridLayout()
self.tab4.setLayout(self.tab4_layout)
self.listwidget4 = QListWidget(self.tab4)
# self.listwidget4.doubleClicked.connect(lambda: self.change_func(self.listwidget))
self.listwidget4.setStyleSheet(self.css)
self.listwidget4.setObjectName("listWidget4")
self.tab4_layout.addWidget(self.listwidget4, 0, 0, 1, 1)
self.tabWidget.addTab(self.tab4, " 歌词 ")
self.tab5 = QWidget()
self.tab5.setObjectName("tab5")
self.tab5_layout = QGridLayout()
self.tab5.setLayout(self.tab5_layout)
self.listwidget5 = QListWidget(self.tab5)
self.listwidget5.doubleClicked.connect(lambda: self.change(self.listwidget5))
self.listwidget5.setContextMenuPolicy(Qt.CustomContextMenu)
self.listwidget5.customContextMenuRequested[QPoint].connect(self.myListWidgetContext5)
self.button_12351 = QPushButton(icon('fa.download', color='#D0D0D0', font=24), "添加目录")
self.button_12351.clicked.connect(self.add)
self.button_12351.setStyleSheet(
'''QPushButton{background:#222225;border-radius:5px;}QPushButton:hover{background:#303030;}''')
self.tab5_layout.addWidget(self.button_12351, 0, 2, 1, 1)
self.button_12361 = QPushButton(icon('fa.trash-o', color='#D0D0D0', font=24), "清空列表")
self.button_12361.clicked.connect(self.dellocal)

self.tab5_layout.addWidget(self.button_12361, 0, 3, 1, 1)
self.listwidget5.setStyleSheet(self.css)
self.listwidget5.setObjectName("listWidget5")
self.tab5_layout.addWidget(self.listwidget5, 1, 0, 1, 4)
self.tabWidget.addTab(self.tab5, " 本地歌曲 ")
self.right_layout.addWidget(self.tabWidget, 3, 0, 100, 90)
UI界面布局实现效果如下：
2. 音乐本地下载及添加我喜爱的歌曲
通过多线程，将歌曲、歌手、歌曲url地址全都获取；并将这些爬取的音乐数据列表显示到搜索页面中。双击列表页面中某一首歌曲，即可实现音乐播放功能。
V2.0版本中，我们添加了对当前播放音乐的本地下载、搜索页音乐列表一键下载、喜爱的歌列表一键下载、添加我喜爱的歌曲功能。
** 音乐下载： **
对于音乐下载，我们可以进行当前播放音乐下载、搜索页音乐列表一键下载、喜爱的歌一键下载。如下图所示：
核心代码如下：
# 当前播放音乐下载
def down(self):
if bo == 'local':
downpath = str(filew)
downpath = downpath.replace('/', '\\')
downpath = downpath + SongName[num]
print(downpath)
print('explorer /select,{}'.format(downpath))
call('explorer /select,{}'.format(downpath))
else:
call('explorer /select,{}'.format(to))
# 下载所有音乐
def downloadall(self, typer):
try:
global typerr
typerr = typer
print(typer)
print(typerr)
self.work = downall()
self.work.start()
self.work.trigger.connect(self.disdownall)
except:
print('默认图片下载错误')
pass
# 下载搜索页列表所有音乐
def downloadalls(self):
self.downloadall('boing')
# 下载喜爱的歌列表所有音乐
def downloadalllove(self):
self.downloadall('love')
** 添加喜爱的歌： **
对于添加喜爱的歌曲，我们可以通过当前播放音乐的❤标志，也可以通过右键音乐列表进行喜爱的歌曲添加。核心代码如下：
# 通过点击❤标志，对当前播放音乐添加喜爱的歌
def lovesong(self):
if bo == 'boing' or bo == 'boed':
try:
global loves
global loveurls
global lovepics
global lovelrc
if bo == 'boing':
loves.append(songs[num])
loveurls.append(urls[num])
lovepics.append(pic[num])
lovelrc.append(lrcs[num])
elif bo == 'boed':
loves.append(songed[num])
loveurls.append(urled[num])
lovepics.append(picd[num])
lovelrc.append(lrcd[num])
else:
pass
except:
pass
self.work = firstThread()
self.work.start()
self.work.trigger.connect(self.dispng)
r = 0
self.listwidget3.clear()
for i in loves:
self.listwidget3.addItem(i)
self.listwidget3.item(r).setForeground(Qt.white)
r = r + 1
print(loves)
else:
pass
# 通过右键音乐列表进行喜爱的歌曲添加
def addItem(self):
try:
global loves
global loveurls
global lovepics
global lovelrc
if list_confident == 'boing':
loves.append(songs[num_m])
loveurls.append(urls[num_m])
lovepics.append(pic[num_m])
lovelrc.append(lrcs[num_m])
else:
loves.append(songed[num_m])
loveurls.append(urled[num_m])
lovepics.append(picd[num_m])
lovelrc.append(lrcd[num_m])
self.work = firstThread()
self.work.start()
self.work.trigger.connect(self.dispng)
except:
pass
r = 0
self.listwidget3.clear()
for i in loves:
self.listwidget3.addItem(i)
self.listwidget3.item(r).setForeground(Qt.white)
r = r + 1
print('done')
print(loves)
这样我们就可以把歌曲添加到喜爱的歌子列表页面下，如下图所示。
3. 喜爱的歌初始化读取显示及列表播放
对于添加到喜爱的歌曲列表，我们需要在退出音乐播放器程序时，将这些数据保存到本地文件，方便后面重新运行时初始化读取显示列表。
** 喜爱歌曲本地保存： ** 我们可以把喜爱的歌曲列表、喜爱歌曲图片、歌曲url链接、歌词等数据保存到本地。核心代码如下：
def close(self):
reply = QMessageBox.question(self, u'警告', u'确定退出?', QMessageBox.Yes,
QMessageBox.No)
if reply == QMessageBox.Yes:
close = True
try:
mixer.music.stop()
except:
pass
try:
rmtree(str(data))
except Exception as e:
print('删除错误类型是', e.__class__.__name__)
print('删除错误明细是', e)
filepath = '{}/musicdata'.format(apdata)
try:
mkdir(filepath)
except:
pass
print(filepath)
with open(filepath + "/loves", 'w', encoding='utf-8') as f:
f.truncate(0)
print(f.write(str(loves)))
with open(filepath + "/lovepics", 'w', encoding='utf-8') as f:
f.truncate(0)
print(f.write(str(lovepics)))
with open(filepath + "/loveurls", 'w', encoding='utf-8') as f:
f.truncate(0)
print(f.write(str(loveurls)))
with open(filepath + "/lovelrc", 'w', encoding='utf-8') as f:
f.truncate(0)
print(f.write(str(lovelrc)))
with open(filepath + "/voice", 'w', encoding='utf-8') as f:
f.truncate(0)
print(f.write(str(voice)))
try:
rmtree(str(data))
except Exception as e:
print('删除错误类型是', e.__class__.__name__)
print('删除错误明细是', e)
exit()
else:
pass
** 喜爱的歌初始化读取： **
重新运行音乐播放器时，我们需要加载保存在本地的喜爱歌曲数据，并将歌曲列表信息加载显示到喜爱的歌子列表页面中。核心代码如下：
def run(self):
try:
apdataas = getenv("APPDATA")
filepathas = '{}/musicdata'.format(apdataas)
global lovelrc
global loveurls
global loves
global lovepics
global voice
# 读取历史数据开始
try:
with open(filepathas + "/voice", 'r', encoding='utf-8') as f:
a = f.read()
# print(a)
voice = float(a)
print(voice)
self.trigger.emit(str('voicedone'))
except:
self.trigger.emit(str('voicedone'))
pass
with open(filepathas + "/loves", 'r', encoding='utf-8') as f:
a = f.read()
print(a)
strer = a
loves = literal_eval(strer)
with open(filepathas + "/lovepics", 'r', encoding='utf-8') as f:
a = f.read()
print(a)
strer = a
lovepics = literal_eval(strer)
with open(filepathas + "/loveurls", 'r', encoding='utf-8') as f:
a = f.read()
print(a)
strer = a
loveurls = literal_eval(strer)
with open(filepathas + "/lovelrc", 'r', encoding='utf-8') as f:
a = f.read()
print(a)
strer = a
lovelrc = literal_eval(strer)
self.trigger.emit(str('login'))
print(loves)
print('read finish')
except:
print('read error')
pass
# 读取数据结束
# 下载喜爱的歌列表中首项的歌曲封面
try:
req = get(lovepics[0])
checkfile = open(str(data + '/ls3.png'), 'w+b')
for i in req.iter_content(100000):
checkfile.write(i)
checkfile.close()
lsfile = str(data + '/ls3.png')
safile = str(data + '/first.png')
draw(lsfile, safile)
self.trigger.emit(str('first'))
except:
self.trigger.emit(str('nofirst'))
pass
** 列表播放： **
对于加载的喜爱歌曲列表，我们可以对歌曲进行列表一键播放。
# 音乐播放
def bofang(self, num, bo):
print('尝试进行播放')
try:
import urllib
global pause
global songs
global music
global downloading
downloading = True
self.console_button_3.setIcon(icon('fa.pause', color='#F76677', font=18))
pause = False
try:
mixer.stop()
except:
pass
mixer.init()
try:
self.Timer = QTimer()
self.Timer.start(500)
except:
pass
try:
self.label.setText('正在寻找文件...')
self.work = WorkThread()
self.work.start()
self.work.trigger.connect(self.display)
except:
print('无法播放，歌曲下载错误')
downloading = False
pass
except:
sleep(0.1)
print('播放系统错误')
pass
# 播放所有歌曲
def playall(self, typer):
global num
global bo
try:
bo = typer
num = 0
self.bofang(bo, num)
except:
print('playall error')
pass
# 播放喜爱歌曲
def allplaylove(self):
self.playall('love')
4. 歌词显示
对于播放的歌曲，我们可以进行歌词打印显示。核心代码如下：
def run(self):
if bo == 'love':
try:
proxies = {
'http': 'http://124.72.109.183:8118',
'http': 'http://49.85.1.79:31666'
}
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36',
'X-Requested-With': 'XMLHttpRequest'}
try:
try:
try:
aq = lovepics[num]
aqq = aq.split('/')
except:
pass
if type == 'kugou' and len(aqq) - 1 == 6:
aqqe = str(aqq[0]) + str('//') + str(aqq[2]) + str('/') + str(aqq[3]) + str('/') + str(
'400') + str('/') + str(aqq[5]) + str('/') + str(aqq[6])
print(aqqe)
elif type == 'netease' and len(aqq) - 1 == 4:
aqn = aq.split('?')
b = '?param=500x500'
aqqe = (str(aqn[0]) + str(b))
print(aqqe)
else:
aqqe = lovepics[num]
req = get(aqqe)
checkfile = open(str(data + '/ls1.png'), 'w+b')
for i in req.iter_content(100000):
checkfile.write(i)
checkfile.close()
lsfile = str(data + '/ls1.png')
safile = str(data + '/back.png')
draw(lsfile, safile)
picno = True
except:
print('图片错误')
picno = False
pass
url1 = loveurls[num]
print(url1)
# os.makedirs('music', exist_ok=True)
number = number + 1
path = str(data + '\{}.临时文件'.format(number))
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.110.430.128 Safari/537.36',
'X-Requested-With': 'XMLHttpRequest'
}
with get(url1, stream=True, headers=headers) as r, open(path, 'wb') as file:
total_size = int(r.headers['content-length'])
content_size = 0
for content in r.iter_content(chunk_size=1024):
if not stopdown:
file.write(content)
content_size += len(content)
plan = (content_size / total_size) * 100
# print(int(plan))
develop = str(int(plan)) + str('%')
self.trigger.emit(str(develop))
else:
print ('down')
break
stopdown = False
to = 'downloadmusic\{}.mp3'.format(songed[num])
makedirs('downloadmusic', exist_ok=True)
except:
self.trigger.emit(str('nofinish'))
pass
try:
lrct = []
f = lovelrc[num] # 按行读取
# print(f)
lines = f.split('\n')
# print(lines)
for i in lines:
line1 = i.split('[')
try:
line2 = line1[1].split(']')
if line2 == '':
pass
else:
linew = line2[1]
# print(linew)
lrct.append(linew)
self.trigger.emit(str('lrcfinish'))
except:
print('歌词错误')
except:
pass
try:
copyfile(path, to)
except:
pass
downloading = False
self.trigger.emit(str('finish'))
except:
self.trigger.emit(str('nofinish'))
效果如下所示：
5. 本地歌曲读取播放
首先我们可以对本地文件夹目录下的音乐进行读取添加到本地歌曲列表中，根据歌曲的文件名进行列表显示。核心代码如下：
# 本地歌曲文件夹读取添加
def add(self):
try:
global SongPath
global SongName
global num
global filew
global asas
fileN = QFileDialog.getExistingDirectory(None, "选取文件夹", "")
if not fileN == '':
self.listwidget5.clear()
filew = fileN + '/'
asas = filew
l1 = [name for name in listdir(fileN) if name.endswith('.mp3') or name.endswith('.flac') or name.endswith('.wma') or name.endswith('.MP3') or name.endswith('.FLAC') or name.endswith('.WMA')]
SongNameadd = l1
SongPathadd = [filew + i for i in SongNameadd]
SongName = SongName + SongNameadd
SongPath = SongPath + SongPathadd
print(SongPath)
r = 0
for i in SongName:
self.listwidget5.addItem(i) # 将文件名添加到listWidget
self.listwidget5.item(r).setForeground(Qt.white)
r = r + 1
except:
filew = asas
当然我们还可以对本地加载歌曲进行双击播放，首先我们需要将本地歌曲子列表页面中进行双击事件绑定。
self.tab5 = QWidget()
self.tab5.setObjectName("tab5")
self.tab5_layout = QGridLayout()
self.tab5.setLayout(self.tab5_layout)
self.listwidget5 = QListWidget(self.tab5)
self.listwidget5.doubleClicked.connect(lambda: self.change(self.listwidget5))
self.listwidget5.setContextMenuPolicy(Qt.CustomContextMenu)
self.listwidget5.customContextMenuRequested[QPoint].connect(self.myListWidgetContext5)
对子列表页面进行绑定之后，接下来我们就可以完成双击事件，获取歌曲名称，并进行本地播放。
# 加载当前播放的本地歌曲
def change(self, listwidget):
global num
global bo
# print (item.flags())
bo = 'local'
num = int(listwidget.currentRow())
print(num)
# self.label.setText(wenjianming)#设置标签的文本为音乐的名字
f = str(SongName[num]).split('.mp3')
f = str(f[0]).split('.flac')
f = str(f[0]).split('.MP3')
f = str(f[0]).split('.FLAC')
f = str(f[0]).split('.wma')
f = str(f[0]).split('.WMA')
self.label.setText(f[0])
print(listwidget.currentRow())
self.bofanglocal()
# 本地音乐播放
def bofanglocal(self):
try:
global pause
try:
self.photo('local')
except:
pass
self.console_button_3.setIcon(icon('fa.pause', color='#F76677', font=18))
pause = False
fill = SongPath[num]
print(fill)
try:
global timenum
mp3 = str(SongPath[num])
xx = load(mp3)
timenum = xx.info.time_secs
global start
start = True
except:
print('进度条错误，播放失败')
try:
mixer.stop()
except:
pass
try:
mixer.music.load(SongPath[num]) # 载入音乐
mixer.music.play() # 播放音乐
except:
print('MP3音频文件出现错误')
except:
sleep(0.1)
print('system error')
self.next()
pass
音乐播放器的本地音乐播放功能效果如下：
