python-从linux上的python中的postfix读取电子邮件

Question

I'm very new to postfix and python. I've setup postfix on Ubuntu and have configured the main.cf with mailbox_command = /home/someuser/test.py

test.py:

#!/usr/bin/python
import sys, MySQLdb

email_input = sys.stdin
db = MySQLdb.connect(host="localhost",
                     user="user", 
                     passwd="password",
                     db="test")

cur = db.cursor()

sql = "insert into postfix (value) values (%s)"
cur.execute(sql, (email_input,))
db.commit()
db.close()

I was expecting the content of the email to be inserted into the field but instead I ended up with <open file '<stdin>', mode 'r' at 0x7f018b3b40c0>

How do I get the raw email string from what seems to be that memory address?

sys.stdin is an object of type TextIOWrapper and cur.execute is expecting a string. You need to instruct sys.stdin to read input and return the string representing it. Use either readline or readlines depending on what you're trying to do.

cur.execute(sql, (sys.stdin.readlines(),))
