                                封装代码如下：

# coding: utf-8  # util.py  import os  import mimetypes  import mimetools  def get_content_type(filepath):      return mimetypes.guess_type(filepath)[0] or 'application/octet-stream'  def encode_multipart_formdata(fields, files=[]):      """     fields is a sequence of (name, value) elements for regular form fields.     files is a sequence of (name, filepath) elements for data to be uploaded as files     Return (content_type, body) ready for httplib.HTTP instance     """      BOUNDARY = mimetools.choose_boundary()      CRLF = '\r\n'      L = []      for (key, value) in fields:          L.append('--' + BOUNDARY)          L.append('Content-Disposition: form-data; name="%s"' % key)          L.append('')          L.append(value)      for (key, filepath) in files:          L.append('--' + BOUNDARY)          L.append('Content-Disposition: form-data; name="%s"; filename="%s"' % (key, os.path.basename(filepath)))          L.append('Content-Type: %s' % get_content_type(filepath))          L.append('')          L.append(open(filepath, 'rb').read())      L.append('--' + BOUNDARY + '--')      L.append('')      body = CRLF.join(L)      content_type = 'multipart/form-data; boundary=%s' % BOUNDARY      return content_type, body  

                                encode_multipart_formdata返回的content_type应设置为content-type头。body即为封装后的数据。
