Question

我正在尝试通过python发送mp3文件。以下是代码 -

for v in videos:

    Thread(target=video_download, args=(handler,v,videos)).start()


def video_download(handler,v,videos):


    try:
        ydl_opts['format'] = 'mp4'
        ydl(ydl_opts).download([v])
    except:
        ydl_opts['format'] = 'best'
        ydl(ydl_opts).download([v])     
    mp3  = open('./'+v+'.mp3', "r+").read()
    handler.send_header('Content-Disposition', 'attachment; filename=%s.mp3' % videos[v])
    handler.wfile.write(mp3)
    handler.end_headers()

它从youtube下载m4a格式的视频并将其转换为mp3文件。下载和转换部分工作正常，它使用线程，但使用wfile.write（）发送文件时，我收到以下错误

Traceback (most recent call last):
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 810, in __bootstrap_inner
    self.run()

    self.__target(*self.__args, **self.__kwargs)
  File "/Users/Keshav/Documents/Github/Webserver/webserver/Downld.py", line 37, in video_download
    handler.send_header('Content-Disposition', 'attachment; filename=%s.mp3' % videos[v])
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/BaseHTTPServer.py", line 401, in send_header
    self.wfile.write("%s: %s\r\n" % (keyword, value))
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 324, in write
    self.flush()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 303, in flush
    self._sock.sendall(view[write_offset:write_offset+buffer_size])
AttributeError: 'NoneType' object has no attribute 'sendall'

如果我实现多处理而不是线程，那么同样的工作完全正常。但它是连续处理而不是并行处理。
