有用第一步请求所获取到底是xml格式的，所以本来想着解析xml来获取lrcid，但是在实现过程中遇到了各种问题，别的还容易，就在这一块儿浪费的时间最长，纠结未果之后，只能改用正则表达式来获取了。。。
使用python将歌词嵌入歌曲中

以前一直用的是Google Play Music来作为手机的音乐播放器，可是现在谷歌被墙的这么厉害的，从PC上传到Google Play的音乐在手机上面同步下来的话特麻烦，索性放弃之买了大名鼎鼎的Poweramp播放器，开始使用之后瞬间就被Poweramp强大的功能所吸引住了，不愧是安卓端的音乐播放器的王者！唯美的锁屏界面，强大的均衡器功能等等。唯一美中不足的就是歌词.如果要显示歌词的话必须安装第三方软件，或者是把歌词嵌入到音乐中。所以昨天下班之后就开始研究，所幸最后终于搞定了，先上下效果图



可以看到，效果还是很不错的呢。

好了，废话不多说，下面上程序

首先，必须安装eyed3模块，还有，我所有的歌词都在E:\lrc这个路径中的




import threading
import time
import datetime
import re
import os
import eyed3
import sys
reload(sys)
sys.setdefaultencoding('utf8')


def getstr(i):
  if i <10:
    return "0"+str(i)
  else:
    return str(i)

musicpath=r'I:\music'

lrcpath=r'E:\lrc'



def deallrc(str):
  mystr=re.sub(r'\[\d\d:\d\d.\d\d\]','',str)
  mystr.replace('\n','')
  return mystr
  


def checklrcfile(path,timespan):
  file=open(path,'r')
  mylrcstr=''
  #print timespan
  for line in file.readlines(100):
    #errorlog(line)
    if line.find(timespan)>0:
      return deallrc(line)
    else:
      continue
  return ''

    
def getlrcstr(lrc):
  mylrcstr=''
  #print lrc
  for i in range(00,05):
    for j in range(00,59):
      for k in range(00,99):
        timespan=getstr(i)+":"+getstr(j)+"."+getstr(k)
        mylrcstr+=checklrcfile(lrc, timespan) 
      #print timespan
  return mylrcstr


def getlrc(musicname):
  musicname=u''.join(musicname)
  musicname=musicname.encode('gb2312')
  for root,dirs,files in os.walk(lrcpath):
    for filepath in files:
      the_path = os.path.join(root,filepath)
      if (the_path.find(musicname) != -1):
        print the_path
        return the_path

def errorlog(path):
  file=open(r'e:\nolrc.txt','a')
  if path is None:
    path=''
  path=path+'\n'
  file.write(path)
  file.close()

def writetag(themusic,lrcstr):
  music=eyed3.load(themusic)
  lrcstr=lrcstr.decode('utf8')
  lrcstr=u''.join(lrcstr)
  #lrcstr=unicode(lrcstr)
  music.tag.lyrics.set(lrcstr)
  music.tag.save()
  
  


def dealmusic(path):
  print path
  the_music = eyed3.load(path)
  the_teg = the_music.tag._getAlbum()
  the_artist = the_music.tag._getArtist()
  the_title = the_music.tag._getTitle()
  #print the_title
  
  try:
    lrc=getlrc(the_title)
    lrcstr=getlrcstr(lrc)
    writetag(path, lrcstr) 
  except:
    errorlog(path)
   
          

class writelrc(threading.Thread):
  def __init__(self,the_path):
    threading.Thread.__init__(self)
    self.thepath=the_path
  def run(self):
    dealmusic(self.thepath)


if __name__=='__main__':
  count=0
  threads=[]
  for root,dirs,files in os.walk(musicpath):
      for filepath in files:
        the_path = os.path.join(root,filepath)
        if (the_path.find("mp3") != -1):
          count+=1
          threads.append(writelrc(the_path))
          if count%10==0:
            for t in threads:
              t.start()
            for t in threads:
              t.join()
            threads=[]     



  
好了，大概就是这样，大家有什么问题可以直接提出来，我会尽快回复的。
