Appengine (Python)의 Google Cloud Storage에 파일 업로드

Question

Google App Engine 응용 프로그램에서 Google Cloud Storage에 파일을 업로드하려고했습니다.

class UploadHandler2(webapp.RequestHandler): 

    def PrintWithCarriageReturn(s): 
    sys.stdout.write('\r' + s) 
    sys.stdout.flush() 
    def post(self): 
form = cgi.FieldStorage(keep_blank_values = 1) 
    print form.keys() 
    fileitem = form['files'] 
if fileitem.filename: 
     filename = os.path.basename(fileitem.filename)** 

하는 사람이 어떤 조언을 주시겠습니까 : 내 서버 측 파이썬 스크립트

입니다 : 이것은 내 클라이언트 측 업로드 양식입니다

File "/base/data/home/runtimes/python27/python27_dist/lib/python2.7/cgi.py", line 540, in __getitem__ 
raise KeyError, key KeyError: 'files' 

:하지만 난이 오류 메시지가 계속 이 코드가 잘못 되었습니까? 감사합니다

Answer 1

요청을 처리하기 위해 webapp를 사용하고 있습니다. 귀하의 cgi.FieldStorage가 데이터를받지 못하는 것처럼 보입니다. 따라서 양식 객체에 '파일'이 없으므로 KeyError가 발생합니다. 웹 애플리케이션에 대한

, 당신은 할 수 있습니다 :

def post(self): 
    fileitem = self.request.POST.get('files', None) 

    fileblob = fileitem.file.read() 
    filename = fileitem.filename 
    mimetype = fileitem.type 

(해당 오류 검사와이 없음을 위해, 물론).
