我正在尝试使用 Weasyprint 从 HTML 模板生成 pdf 文件python 包，我需要通过电子邮件发送它。
这是我尝试过的:
def send_pdf(request):
minutes = int(request.user.tagging.count()) * 5
testhours = minutes / 60
hours = str(round(testhours, 3))
user_info = {
"name": str(request.user.first_name + ' ' + request.user.last_name),
"hours": str(hours),
"taggedArticles": str(request.user.tagging.count())
}
html = render_to_string('users/certificate_template.html',
{'user': user_info})
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'filename=certificate_{}'.format(user_info['name'] + '.pdf')
pdf = weasyprint.HTML(string=html).write_pdf(response, )
from_email = 'our_business_email_address'
to_emails = ['Reciever1', 'Reciever2']
subject = "Certificate from INC."
message = 'Enjoy your certificate.'
email = EmailMessage(subject, message, from_email, to_emails)
email.attach("certificate.pdf", pdf, "application/pdf")
email.send()
return HttpResponse(response, content_type='application/pdf')
But it returns an error as
TypeError: expected bytes-like object, not HttpResponse
如何从 HTML 模板生成 pdf 文件并将其发送到电子邮件？
Update: With this updated code now it's generating pdf and sending an email but when I open attached pdf file from recieved email it says
unsupported file formate data.
这是更新后的代码:
def send_pdf(request):
minutes = int(request.user.tagging.count()) * 5
testhours = minutes / 60
hours = str(round(testhours, 3))
user_info = {
"name": str(request.user.first_name + ' ' + request.user.last_name),
"hours": str(hours),
"taggedArticles": str(request.user.tagging.count())
}
html = render_to_string('users/certificate_template.html',
{'user': user_info})
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'filename=certificate_{}'.format(user_info['name']) + '.pdf'
pdf = weasyprint.HTML(string=html).write_pdf()
from_email = 'arycloud7@icloud.com'
to_emails = ['abdul12391@gmail.com', 'arycloud7@gmail.com']
subject = "Certificate from Nami Montana"
message = 'Enjoy your certificate.'
email = EmailMessage(subject, body=pdf, from_email=settings.EMAIL_HOST_USER, to=to_emails)
# email.attach("certificate.pdf", pdf, "application/pdf")
email.content_subtype = "pdf" # Main content is now text/html
email.encoding = 'ISO-8859-1'
email.send()
return HttpResponse(pdf, content_type='application/pdf')
请帮帮我!
提前致谢!
请您参考如下方法:
这是上面代码的完整工作版本:
user_infor = ast.literal_eval(ipn_obj.custom)
if int(user_infor['taggedArticles']) > 11:
# generate and send an email with pdf certificate file to the user's email
user_info = {
"name": user_infor['name'],
"hours": user_infor['hours'],
"taggedArticles": user_infor['taggedArticles'],
"email": user_infor['email'],
}
html = render_to_string('users/certificate_template.html',
{'user': user_info})
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'filename=certificate_{}'.format(user_info['name']) + '.pdf'
pdf = weasyprint.HTML(string=html, base_url='http://8d8093d5.ngrok.io/users/process/').write_pdf(
stylesheets=[weasyprint.CSS(string='body { font-family: serif}')])
to_emails = [str(user_infor['email'])]
subject = "Certificate from Nami Montana"
email = EmailMessage(subject, body=pdf, from_email=settings.EMAIL_HOST_USER, to=to_emails)
email.attach("certificate_{}".format(user_infor['name']) + '.pdf', pdf, "application/pdf")
email.content_subtype = "pdf" # Main content is now text/html
email.encoding = 'us-ascii'
email.send()
