可以通过以下步骤实现:
APIView
类或者ViewSet
类来实现。FileField
来处理文件上传,并设置upload_to
参数指定文件保存的路径。Attachment
类来实现。以下是一个示例代码:
from rest_framework.views import APIView
from sendgrid.helpers.mail import Mail, Attachment
from django.core.mail import send_mail
from django.conf import settings
class FileUploadAPIView(APIView):
def post(self, request):
file = request.FILES.get('file')
# 保存文件到服务器的临时目录
file_path = 'path/to/temp/directory/' + file.name
with open(file_path, 'wb+') as destination:
for chunk in file.chunks():
destination.write(chunk)
# 创建sendgrid邮件对象
message = Mail(
from_email='from@example.com',
to_emails='to@example.com',
subject='File Attachment',
plain_text_content='Please find the attached file.'
)
# 创建sendgrid附件对象
with open(file_path, 'rb') as file:
attachment = Attachment()
attachment.file_content = file.read()
attachment.file_type = file.content_type
attachment.file_name = file.name
attachment.disposition = 'attachment'
message.attachment = attachment
# 发送邮件
try:
sendgrid_client.send(message)
# 发送成功后删除临时文件
os.remove(file_path)
return Response({'message': 'Email sent successfully.'})
except Exception as e:
return Response({'message': 'Failed to send email.'}, status=status.HTTP_500_INTERNAL_SERVER_ERROR)
这个示例代码演示了如何在使用django-rest-framework和sendgrid发送电子邮件时附加文件。你可以根据自己的需求进行修改和扩展。
