音乐是一个好东西,听着可以令人心情舒畅,2017年定下一个小目标,带上女票去听一场演唱会
背景
搜了一下很多无损音乐资源基本上都是专辑,找到单曲下载的比较少,就算找到了,也要每个专辑搜素一遍,再云盘Ctrl+c、Ctrl+v下载,整个过程繁琐,实在不能容忍。不说了,我们要实现自动化下载flac无损音乐到本地。来听一场轻松,无损的音乐盛宴。
实现
人生苦短,我用Python
-
利用Python爬取网易云音乐歌单中的所有flac无损音乐进行下载
- Python3.5代码
import re
import requests
import json
import urllib.request
import urllib.error
import os
import sys
minimumsize = 10
print("fetching msg from %s \n" % sys.argv[1])
url = re.sub("#/", "", sys.argv[1])
r = requests.get(url)
contents = r.text
res = r'<ul class="f-hide">(.*?)</ul>'
mm = re.findall(res, contents, re.S | re.M)
CURRENT_PATH = os.path.dirname(os.path.realpath(__file__))
if(mm):
contents = mm[0]
else:
print('Can not fetch information form URL. Please make sure the URL is right.\n')
os._exit(0)
res = r'<li><a .*?>(.*?)</a></li>'
mm = re.findall(res, contents, re.S | re.M)
for value in mm:
url = 'http://sug.music.baidu.com/info/suggestion'
payload = {'word': value, 'version': '2', 'from': '0'}
print(value)
r = requests.get(url, params=payload)
contents = r.text
d = json.loads(contents, encoding="utf-8")
if d is not None and 'data' not in d:
continue
songid = d["data"]["song"][0]["songid"]
print("find songid: %s" % songid)
url = "http://music.baidu.com/data/music/fmlink"
payload = {'songIds': songid, 'type': 'flac'}
r = requests.get(url, params=payload)
contents = r.text
d = json.loads(contents, encoding="utf-8")
if('data' not in d) or d['data'] == '':
continue
songlink = d["data"]["songList"][0]["songLink"]
print("find songlink: ")
if(len(songlink) < 10):
print("\tdo not have flac\n")
continue
print(songlink)
songdir = "songs_dir"
if not os.path.exists(songdir):
os.makedirs(songdir)
songname = d["data"]["songList"][0]["songName"]
artistName = d["data"]["songList"][0]["artistName"]
filename = ("%s/%s/%s-%s.flac" %
(CURRENT_PATH, songdir, songname, artistName))
f = urllib.request.urlopen(songlink)
headers = requests.head(songlink).headers
size = round(int(headers['Content-Length']) / (1024 ** 2), 2)
#Download unfinished Flacs again.
if not os.path.isfile(filename) or os.path.getsize(filename) < minimumsize: #Delete useless flacs
print("%s is downloading now ......\n\n" % songname)
if size >= minimumsize:
with open(filename, "wb") as code:
code.write(f.read())
else:
print("the size of %s (%r Mb) is less than 10 Mb, skipping" %
(filename, size))
else:
print("%s is already downloaded. Finding next song...\n\n" % songname)
print("\n================================================================\n")
print("Download finish!\nSongs' directory is %s/songs_dir" % os.getcwd())
使用
- 执行music.py。后面跟上歌单的网页地址
python music.py http://music.163.com/#/playlist?id=7751674
- 接下来就带上耳机听着无损音乐吧!
