How to read emails from gmail?-CodePudding

I am trying to connect my gmail to python, but show me this error:

I already checked my password, any idea what can be?

b'[AUTHENTICATIONFAILED] Invalid credentials (Failure)'
Traceback (most recent call last):
  File "/Users/myuser/Documents/migrations/untitled3.py", line 29, in read_email_from_gmail
    mail.login(FROM_EMAIL,FROM_PWD)
  File "/Users/myuser/opt/anaconda3/lib/python3.9/imaplib.py", line 612, in login
    raise self.error(dat[-1])
imaplib.IMAP4.error: b'[AUTHENTICATIONFAILED] Invalid credentials (Failure)'

Here my code: Also i want to know which port I can use?

import smtplib
import time
import imaplib
import email
import traceback 

ORG_EMAIL = "@gmail.com" 
FROM_EMAIL = "myemail"   ORG_EMAIL 
FROM_PWD = "mypassword" 
SMTP_SERVER = "smtp.gmail.com" 
SMTP_PORT = ??

def read_email_from_gmail():
    try:
        mail = imaplib.IMAP4_SSL(SMTP_SERVER)
        mail.login(FROM_EMAIL,FROM_PWD)
        mail.select('inbox')

        data = mail.search(None, 'ALL')
        mail_ids = data[1]
        id_list = mail_ids[0].split()   
        first_email_id = int(id_list[0])
        latest_email_id = int(id_list[-1])

        for i in range(latest_email_id,first_email_id, -1):
            data = mail.fetch(str(i), '(RFC822)' )
            for response_part in data:
                arr = response_part[0]
                if isinstance(arr, tuple):
                    msg = email.message_from_string(str(arr[1],'utf-8'))
                    email_subject = msg['subject']
                    email_from = msg['from']
                    print('From : '   email_from   '\n')
                    print('Subject : '   email_subject   '\n')

    except Exception as e:
        traceback.print_exc() 
        print(str(e))

read_email_from_gmail()

My main goal is be able to get the CSV file from each email, but for now I just want to read messages.

CodePudding user response：

You need to enable 'Less secure apps' in your Gmail account if you're going to check it this way. For that reason, it would be better to use the Gmail API.
SMTP port is not set - ensure you are using the correct port (993)

CodePudding user response：

Here's the problem, Gmail has a new politic who doesn't allow to use insecure apps.

To help keep your account secure, from May 30, 2022, Google no longer supports the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password.
