我一直在尝试使用openpyxl发送excel作为电子邮件附件，而没有在Django中保存[On The Fly]
您可以将工作簿对象保存到BytesIO实例中(from io import BytesIO)
output = BytesIO()
workbook.save(output)
你可以使用Django的EmailMessage类来创建你的电子邮件，并将你的BytesIO对象附加为文件作为第二个参数。
email = EmailMessage(
'Hello',
'Body goes here',
'from@example.com',
['to1@example.com', 'to2@example.com'],
['bcc@example.com'],
reply_to=['another@example.com'],
headers={'Message-ID': 'foo'},
)
email.attach('file.xlsx', output.getvalue() , 'application/vnd.ms-excel')
请复习下次如何请求:)
这是一个通过电子邮件发送excel文件的示例。
from io import BytesIO
import xlwt
from django.core.mail import EmailMessage
def send_excel_email():
excelfile = BytesIO()
wb = xlwt.Workbook(encoding='utf-8')
ws = wb.add_sheet('Sheetname')
ws.write(0, 0, 'Firstname')
ws.write(0, 1, 'Surname')
ws.write(1, 0, 'Hans')
ws.write(1, 1, 'Muster')
wb.save(excelfile)
email = EmailMessage()
email.subject = 'This subject'
email.body = 'This context'
email.from_email = 'from@example.com'
email.to = ['your_email@gmail.com']
email.attach('test_file.xls', excelfile.getvalue(), 'application/ms-excel')
email.send()
下面是我使用Django 2, Python 3和openxl的方法
from io import BytesIO
output = BytesIO() # Create a file like object in memory
wb_object.save(output) # Write my workbook object into that memory
# Setup my email
msg = EmailMultiAlternatives(subject, "", from_email, to_email, cc=cc, bcc=bcc)
# Attach the excel file with a name, the actual attachment , and a MIMEtype.
msg.attach('my_invoice.xlsx', output.getvalue(), 'application/vnd.ms-excel')
#The content here is the email content in its body and its type which is just text.
msg.attach_alternative(content, "text/html")
# Now send it .
msg.send()
