python - 使用 plone.api 创建文件的脚本 Python 在设置文件时出现错误 WrongType

Question

亲爱的，

我正在创建一个脚本 python 以在 Plone 站点批量上传文件，安装的是 UnifiedInstaller Plone 4.3.10。

这个脚本读取了一个txt，这个txt用分号隔开，在新建的item中建立文件时出现这个错误。

吼叫脚本。

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()

当脚本将设置文件时，出现错误“WrongType”。请参阅下面的详细信息。

感谢您的关注!

您需要将文件名作为 unicode 传递。

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