How to upload files >10MB with resumable uploads to Google Bucket using Python -

i have app uploads videos less 10mb specified google cloud storage bucket, however, not file greater 10mb.

i know how resumable uploads. not want links documentation, have read of documentation. not help.

i doing in python. understand me resumable upload need authorization token , have no idea how that. 1 me code?

here code post videos < 10mb

class getdata(webapp2.requesthandler): def post(self):     data = self.request.get('file')     bucketname = self.request.get('bucketname')     typeof = self.request.get('content_type')     sender = self.request.get('sender')     profilevideo = self.request.get('isprofilevideo')     file_path = ''      = time.time()     objectname =      try:         keytext = open(conf.private_key_path, 'rb').read()     except ioerror e:         sys.exit('error while reading private key: %s' % e)      private_key = rsa.importkey(keytext)        signer = cloudstorageurlsigner(private_key, conf.service_account_email,                                  gcs_api_endpoint)     subdirectory = 'videomesseagesfrom' + sender     if profilevideo == 'true':         file_path = '/%s/profile_videos/%s' % (bucketname, objectname)          r = signer.put(file_path, typeof, data)     else:         file_path = '/%s/%s/%s' % (bucketname, subdirectory, objectname)         r = signer.put(file_path, typeof, data)       self.response.headers['content-type'] = 'application/json'       obj = {                'completion' : 'video uploaded'                }      self.response.out.write(json.dumps(obj))  

i pass in file , bucket name. grabs credentials google generated key in project , signs put url, puts me.

def put(self, path, content_type, data):     """performs put request.     args:       path: relative api path access, e.g. '/bucket/object'.       content_type: content type assign upload.       data: file data upload new file.     returns:       instance of requests.response containing http response.     """     md5_digest = base64.b64encode(md5.new(data).digest())      base_url, query_params = self._makeurl('put', path, content_type,                                            md5_digest)     headers = {}     headers['content-type'] = content_type     headers['content-length'] = str(len(data))     headers['content-md5'] = md5_digest     return self.session.put(base_url, params=query_params, headers=headers,                             data=data) 

it making put request content-type headers , that. maybe put check on this, if file larger 10mb somehow edit put method resumable upload, or upload in chunks. however, have no idea how that.
