python實現各大平台音樂爬取和收聽,下載
先上效果圖
這個是新增加的喜愛的歌的界面
這個是新增的歌曲詳情的界面
最近這段時間沒什么事干，然后我就把整個播放器的界面重構了，並且修復了一些邏輯性的bug
下面就來解析一下代碼
首先是最核心的爬蟲部分：
# 爬蟲線程
trigger = pyqtSignal(str)
def __int__(self):
# 初始化函數
super(PAThread, self).__init__()
def run(self):
qmut.lock()
try:

print('開始搜索')

}

if int(page) == '' or int(page) < 1:
pages = 2
else:

print(pages)

for a in range(1, pages + 1):
if not stop:

'http://music.laomao.me/']
print(tryed)
if tryed > 3:
tryed = 0
url = urlss[tryed]
else:
url = urlss[tryed]
print(urlss[tryed])
params = {'input': name,
'filter': 'name',
'type': type,
'page': a
}
# 爬蟲核心
if not stop:
try:
# 獲取json文件

html = res.json()
for i in range(0, 10):
try:
# 處理文件

url1 = jsonpath(html, '$..url')[i] # 取下載網址

lrc = jsonpath(html, '$..lrc')[i]
print(title, author)
lrcs.append(lrc)
urls.append(url1)
pic.append(pick)
songs.append(str(title) + ' - ' + str(author))
# self.textEdit.setText(lrc) # 打印歌詞

qmut.unlock()
然后就是從爬取的url下載歌曲，由於我設計了多個歌單，所以download類比較復雜,由於篇幅問題，我就不在這里展出了
