I'm struggling with the create_message_with_attachment (the rest works, create_message_without_attachment works ).
I did read google documentation. The stack thread talking about it focus on complicate point (while mixing up the different python version). Posting this in stack will be down-voted as duplicated (stack has its limit). The script bellow only create an email attach a file to it and send it (well, it's suppose to do so) This script return: encoders.encode_base64(part) NameError: name 'encoders' is not defined import httplib2 import os import oauth2client from oauth2client import client, tools import base64 from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.mime.base import MIMEBase from apiclient import errors, discovery SCOPES = 'https://www.googleapis.com/auth/gmail.send' CLIENT_SECRET_FILE = 'client_secret.json' APPLICATION_NAME = 'Gmail API Python Send Email' def get_credentials(): home_dir = os.path.expanduser('~') credential_dir = os.path.join(home_dir, '.credentials') if not os.path.exists(credential_dir): os.makedirs(credential_dir) #create folder if doesnt exist credential_path = os.path.join(credential_dir, 'gmail-python-email-send.json') store = oauth2client.file.Storage(credential_path) credentials = store.get() if not credentials or credentials.invalid: flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES) flow.user_agent = APPLICATION_NAME credentials = tools.run_flow(flow, store) print('Storing credentials to ' + credential_path) return credentials def SendMessage(sender, to, subject, msgHtml, msgPlain): credentials = get_credentials() http = httplib2.Http() http = credentials.authorize(http) service = discovery.build('gmail', 'v1', http=http) # #without attachment # message_without_attachment = create_message_without_attachment(sender, to, subject, msgHtml, msgPlain) # SendMessageInternal(service, "me", message_without_attachment) # #with attachement message_with_attach = create_message_with_attachment(sender, to, subject, msgHtml, msgPlain) SendMessageInternal(service, "me", message_with_attach) def SendMessageInternal(service, user_id, message): try: message = (service.users().messages().send(userId=user_id, body=message). execute()) ####need to get user_id before message_ID = message['id'] print(f'Message Id: {message_ID}') return [message, message_ID] #return value as list except errors.HttpError as error: print(f'An error occurred: {error}') def create_message_without_attachment (sender, to, subject, msgHtml, msgPlain): msg = MIMEMultipart('alternative') msg['Subject'] = subject msg['From'] = sender msg['To'] = to msg.attach(MIMEText(msgPlain, 'plain')) msg.attach(MIMEText(msgHtml, 'html')) raw = base64.urlsafe_b64encode(msg.as_bytes()) raw = raw.decode() body = {'raw': raw} return body def create_message_with_attachment(sender, to, subject, msgHtml, msgPlain): msg = MIMEMultipart('alternative') msg['To'] = to msg['From'] = sender msg['Subject'] = subject msg.attach(MIMEText(msgPlain, 'plain')) msg.attach(MIMEText(msgHtml, 'html')) # the problem comes from this part part = MIMEBase('application', "octet-stream") part.set_payload( open(r"C:\Users\xx\Desktop\test_Attachment.txt","rb"). read() ) encoders.encode_base64(part) part.add_header('Content-Disposition', 'attachment; filename="{0}"'.format( os.path.basename(f))) msg.attach(part) raw = base64.urlsafe_b64encode(msg.as_bytes()) raw = raw.decode() body = {'raw': raw} return body def main(): to = "yourem...@gmail.com" sender = "myem...@gmail.com" subject = "subject test1" msgHtml = r'Hi<br/>Html <b>hello</b>' msgPlain = "Hi\nPlain Email" message_text= "this is message text" SendMessage(sender, to, subject, msgHtml, msgPlain) if __name__ == '__main__': main() -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
