機械化開放的功能，給予BadStatusLine：'錯誤

Question

我寫這個劇本下載歌詞我的歌曲，並將它們存儲在一個文本文件：

>>> lis = os.listdir('D:\Phone\Sounds') 
>>> for i in lis: 
    print i 

    br.open('http://www.azlyrics.com/') # THE PROBLEM 

    br.select_form(nr=0) 
    track = eyed3.load(i).tag 
    if(track.artist != None): 
     ft = track.artist.find('ft.') 
     if(ft != -1): 
      br['q'] = track.title + ' ' + track.artist[:ft] 
     else: 
      br['q'] = track.title + ' ' + track.artist 
    else: 
     br['q'] = track.title 
    br.submit() 
    s = BeautifulSoup(br.response().read()) 
    a = s.find('div',{'class':'sen'}) 
    if(a != None): 
     s = BeautifulSoup(urllib.urlopen(a.find('a')['href'])) 
     file = open(i.replace('.mp3','.txt'),'w') 
     file.write(str(s.find('div',{'style':'margin-left:10px;margin-right:10px;'})).replace('<br />','\n')) 
     file.close() 
    else: 
     print 'Lyrics not found' 

這似乎是工作了一段時間，我下載的歌詞對於一些歌曲，並突然它引發BadStatusLine錯誤

那麼，爲什麼br.open函數突然停止工作？ 在此先感謝。

Answer 1

當它不理解響應狀態碼時，由httplib生成錯誤。引用自docs：

HTTPException的子類。如果服務器用我們不明白的HTTP 狀態碼進行響應，則引發此問題。

運行時我還沒有收到任何錯誤br.open('http://www.azlyrics.com/')。所以，問題就在你身邊。

很有可能您使用的是代理服務器，請參閱Python's mechanize proxy support。

UPD： 試用一下這個：

br = mechanize.Browser() 
br.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')] 

br.set_debug_http(True) 
br.set_debug_redirects(True) 
br.set_debug_responses(True) 

br.open('http://www.azlyrics.com') 

print br.response().read() 

希望有所幫助。
