Script Python using plone.api to create File appear error WrongType when set a file

问题

Dears,

I'm creating a script python to mass upload files in Plone site, the installation is UnifiedInstaller Plone 4.3.10.

This script read a txt, and this txt have separation with semicolon, the error appear when set up a file in a new created item.

Bellow the Script.

from zope.site.hooks import setSite
from plone.namedfile.file import NamedBlobFile
from plone import api
import transaction
import csv

portal = app['Plone']
setSite(portal)
container = portal['PROCESSOS']

with open('CARGA/C008_0002.txt', 'rb') as csvfile:
    reader = csv.DictReader(csvfile, delimiter=';', quotechar='|')
    for row in reader:
        pdf_id = 'P'+str(row['IMAGEM']).strip('Pasta Geral\\ ')
        file_obj = api.content.create(                          
            container, 'File',
            title=str(row['INTERESSADO']),
            id=pdf_id,
            description=str(row['CNPJ / CPF'])+' '+str(row['ASSUNTO']),
            safe_id=True
        )
        pdf_path = 'INMEQ/'+str(row['IMAGEM']).replace("\\", "/")
        print(pdf_path)
        file_obj.file = NamedBlobFile(
            data=open(pdf_path, 'r').read(),
            contentType='application/pdf',
            filename=str(file_obj.id),
        )
        print('Created: '+row['NDOPROCESSO']+'.')

transaction.commit()

When the script will set up a file the error "WrongType" appear. See verbose bellow.

Traceback (most recent call last):

Thanks for you attention!

You need to pass the filename as unicode.

file_obj.file = NamedBlobFile(
    data=open(pdf_path, 'r').read(),
    contentType='application/pdf',
    filename=unicode(file_obj.id),  # needs to be unicode
)
