python！实现各大平台(网易，酷狗，qq)音乐爬取和收听,下载，第三次更新
python实现各大平台音乐爬取和收听,下载
先上效果图
这个是新增加的喜爱的歌的界面
这个是新增的歌曲详情的界面
最近这段时间没什么事干，然后我就把整个播放器的界面重构了，并且修复了一些逻辑性的bug
下面就来解析一下代码
首先是最核心的爬虫部分：
# 爬虫线程
trigger = pyqtSignal(str)
def __int__(self):
# 初始化函数
super(PAThread, self).__init__()
def run(self):
qmut.lock()
try:
global paing
global stop
global lrcs
global urls
global songs
global name
global songid
global proxies
global pic
global tryed
paing = True
print('搜索软件{}'.format(type))
print('开始搜索')
name = name
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'
}
urls = []
songs = []
pic = []
lrcs = []
if int(page) == '' or int(page) < 1:
pages = 2
else:
pages = int(page)
print(pages)
if not name == '':
for a in range(1, pages + 1):
if not stop:
urlss = ['http://music.9q4.cn/', 'https://defcon.cn/dmusic/', 'http://www.xmsj.org/',
'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
}
# 爬虫核心
if not stop:
try:
# 获取json文件
res = post(url, params, headers=headers, proxies=proxies)
html = res.json()
for i in range(0, 10):
try:
# 处理文件
title = jsonpath(html, '$..title')[i]
author = jsonpath(html, '$..author')[i]
url1 = jsonpath(html, '$..url')[i] # 取下载网址
pick = jsonpath(html, '$..pic')[i] # 取图片
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) # 打印歌词
# print(lrc)
except:
pass

qmut.unlock()
然后就是从爬取的url下载歌曲，由于我设计了多个歌单，所以download类比较复杂,由于篇幅问题，我就不在这里展出了
