Pythonを使用して大きなファイルをPOSTする方法を検索した後、これに出会い、それに基づいてプログラムを作成しましたが、実行すると次のエラーメッセージが表示されます。

これが私のコードです。私が使用するプログラムを実行します--upload "path_to_file" [space] "filename"。私はPythonプログラミングが初めてなので、これのほとんどがまだ私を混乱させています。
def do_upload(options, args):
url = 'http://127.0.0.1/test_server/upload'
path = args[0]
# print path
filename = args[1]
if not os.access(args[0], os.F_OK):
print "Directory/file Doesn't exist"
exit(1)
os.chdir(path)
f = open(filename, 'rb')
mmapped_file_as_string = mmap.mmap(f.fileno(), 0, access=mmap.ACCESS_READ)
request = urllib2.Request(url, mmapped_file_as_string)
contenttype = mimetypes.guess_type(filename)[0]
request.add_header(contenttype, 'application/octet-stream')
response = urllib2.urlopen(request)
#close everything
mmapped_file_as_string.close()
f.close()

上記のコードを変更したところ、ソケット エラーが発生しました。
