问题描述
我正在尝试将PDF文件附加到通过sendgrid发送的电子邮件中.
I'm trying to attach a PDF file to my email sent with sendgrid.
这是我的代码:
sg = sendgrid.SendGridAPIClient(apikey=os.environ.get('SENDGRID_API_KEY')) from_email = Email("from@example") subject = "subject" to_email = Email("to@example") content = Content("text/html", email_body) pdf = open(pdf_path, "rb").read().encode("base64") attachment = Attachment() attachment.set_content(pdf) attachment.set_type("application/pdf") attachment.set_filename("test.pdf") attachment.set_disposition("attachment") attachment.set_content_id(number) mail = Mail(from_email, subject, to_email, content) mail.add_attachment(attachment) response = sg.client.mail.send.post(request_body=mail.get()) print(response.status_code) print(response.body) print(response.headers)但是,Sendgrid Python库抛出错误HTTP错误400:错误的请求.
But the Sendgrid Python library is throwing an error HTTP Error 400: Bad Request.
我的代码有什么问题?
推荐答案我找到了解决方案.我替换了这一行:
I found a solution. I replaced this line :
pdf = open(pdf_path, "rb").read().encode("base64")通过这个:
with open(pdf_path, 'rb') as f: data = f.read() encoded = base64.b64encode(data)现在可以使用了.我可以在set_content中发送编码文件:
Now it works. I can send encoded file in the set_content :
attachment.set_content(encoded)注意:上面的答案适用于Sendgrid v2或更低版本.对于v3及更高版本:
Note: The answer above works for Sendgrid v2 or lower. For v3 and up use:
encoded = base64.b64encode(data).decode()更多推荐
