Python request for Google Drive

Question

I am trying to use python requests library to send a file to Google Drive api. The only thing I need it to send a multipart request according to google documentation https://developers.google.com/drive/web/manage-uploads#multipart I need to send the meta data first and then the file. Here is what I tried so far

    def upload_csv(self, file, description):
      self.refresh()
      url = self.url+'?uploadType=multipart&' + urllib.urlencode({'key':self.api_key})

      headers = { 'Authorization':'Bearer {}'.format(self.access_token),
    #                    'content-type':'multipart/related',
    #                    'content-length':size
                }

      data =  {'title':file,'description':description }
      files = {'file':(file,open(file,'rb'),'text/csv')}
      response = requests.post( url, headers = headers, data = data, files = files )

but I get back an error: u'Bad content type. Please use multipart. Is there a way to send meta data and the file using requests

Answer 1

I figured out a way to do it. The problem is Google wants the meta data and the file together.

    def upload_csv(self, file, description):
      self.refresh()
      url = self.url+'?uploadType=multipart&convert=true' +   urllib.urlencode({'key':self.api_key})

      headers = { 'Authorization':'Bearer {}'.format(self.access_token) }

      class DataDict(dict):
          def read(self):
              return str( self )

      data = ('metadata',DataDict(title = file,description = description),'application/json; charset=UTF-8')
      file = (file,open(file,'rb'),'text/csv')
      files = {'data':data, 'file':file }
      response = requests.post( url, headers = headers, files = files )
      return respone
