Uploading into blobstore using urlfetch

Question

im trying to upload an excel that is obtained from a url using google app engine urlfetch. I can access all its headers. I now need to upload the same into the blobstore. The following is the code i wrote

class Send_Handler(webapp2.RequestHandler):
    def get(self):
        url = "http://abc.xls"
        result = None
        fetch_(url, result, 'GET') 
        #     self.response.out.write(result.content)

def fetch_(url, result, method):
    # logging.info(result)
    if method=='GET':
        result = urlfetch.fetch(url)
        if result.status_code == 200:
            upload_url = blobstore.create_upload_url('/attachupload')
            logging.info(upload_url)
            fetch_(upload_url, result, 'POST')
    else:
        try:
            r_headers = result.headers
            logging.info(result.content)
            result_2 = urlfetch.fetch(url=url, payload=result.content,method=urlfetch.POST, headers=r_headers)
            # logging.info(result_2)
        except Exception, e:
            logging.error(e)

when run, it returns an error "TypeError: not indexable"

The following are the headers i got

alternate-protocol: 80:quic,80:quic server: Google Frontend transfer-encoding: chunked date: Mon, 21 Jul 2014 13:18:16 GMT content-type: application/msexcel cache-control: no-cache content-transfer-encoding: Binary content-disposition: attachment; filename="abc.xls"

this excel file url is obtained from another webapp

Check the answer below since you need to encode your post as it were an html form in order to upload to the blob. — loki

I wrote this Gist a couple of months ago, about uploading a blob to the blobstore using an upload_url and urlfetch. The example code reads an existing blob from the blobstore.

To send a blob to the blobstore you have to send a mulitipart/form-data.
