Python Sendgrid send email with PDF attachment file

Question

I\'m trying to attach a PDF file to my email sent with sendgrid.

Here is my code :

sg = sendgrid.SendGridAPIClient(apikey=os.environ.get(\'SENDGRID_A         


        

Answer 1

I found a solution. I replaced this line :

pdf = open(pdf_path, "rb").read().encode("base64")

By this :

with open(pdf_path, 'rb') as f:
    data = f.read()

encoded = base64.b64encode(data)

Now it works. I can send encoded file in the set_content :

attachment.set_content(encoded)

Note: The answer above works for Sendgrid v2 or lower. For v3 and up use:

encoded = base64.b64encode(data).decode()
