Djangoファイルのアップロード - filenoエラー

Question

ファイル（オーディオファイル）をdjango webappからdjango restサービスにアップロードしようとしています。

形式：

<form method="post" action="/" name="submit" enctype="multipart/form-data"> 
     {% csrf_token %} 
     <input type="file" name="uploaded_file"><br /><br /> 
     <input type="submit" name="submit" value="Submit"> 
</form> 

ビュー：

from poster.streaminghttp import register_openers 
from poster.encode import multipart_encode 
import urllib2 

<...> 

def post(self, request): 
    """ 
    POST request: handles file upload to web service 
    """ 
    uploaded_file = request.FILES['uploaded_file'] 

    server = "http://127.0.0.1:8000" 
    headers = {} 

    # Register the streaming http handlers with urllib2 
    register_openers() 

    data = { 
     'uploaded_file' : uploaded_file, 
     'file_name' : uploaded_file.name, 
     'additionalattr': 111, 
    } 

    datagen, headers = multipart_encode(data) 
    headers['Authorization'] = 'Token <...>' 

    headers['Connection']='keep-alive' 
    urllib_request = urllib2.Request('%s/file_upload/' % (server), datagen, headers) 

    json_response = json.loads(urllib2.urlopen(urllib_request).read()) 

    return <...> 

私はファイルをアップロードすると、私はmultipart_encodeによって引き起こされる、次のエラーコードを取得：

を誰が私を助けることができます何がうまくいかないのか、それをどうやって修正できるのか理解していますか？

ありがとうございます！

がUploadedFileのような問題ではなかったようだ、使用しているposterライブラリを使用すると、コマンドラインまたは任意のIDEから、ジャンゴ・サーバを実行しているから、私の古い答え
