Question

我有以下代码

import smtplib

sender = 'sender@sender.com'
receivers = ['receiver@receiver.com']

message = """From: From Person <sender@sender.com>
To: To Person <receiver@receiver.com>
Subject: We are blending baby !

This is a test e-mail message.
"""

try:
    smtpObj = smtplib.SMTP('localhost')
    smtpObj.sendmail(sender, receivers, message)
    print "Successfully sent email"
except SMTPException:
    print "Error: unable to send email"

从某处复制/粘贴它可以正常工作。

然而。。。一旦包含在我的整个程序中，我收到的电子邮件没有发件人或收件人可用???

它只是空白......但它的代码相同。

import paramiko
import time
import smtplib

def disable_paging(remote_conn):
    '''Disable paging on a Cisco router'''

    remote_conn.send("terminal length 0\n")
    time.sleep(1)

    # Clear the buffer on the screen
    output = remote_conn.recv(1000)

    return output


def main():

    # VARIABLES THAT NEED CHANGED
    ip = '1.2.3.4'
    username = 'xxx'
    password = 'xxx'

    # Create instance of SSHClient object
    remote_conn_pre = paramiko.SSHClient()

    # Automatically add untrusted hosts (make sure okay for security policy in your environment)
    remote_conn_pre.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    # initiate SSH connection
    remote_conn_pre.connect(ip, username=username, password=password, look_for_keys=False, allow_agent=False)

    # Use invoke_shell to establish an 'interactive session'
    remote_conn = remote_conn_pre.invoke_shell()

    # Strip the initial router prompt
    output = remote_conn.recv(1000)

    # Turn off paging
    disable_paging(remote_conn)

    # Now let's try to send the router a command
    remote_conn.send("\n")
    remote_conn.send("show log last 50\n")

    # Wait for the command to complete
    time.sleep(2)

    output = remote_conn.recv(10000)

    if 'bad.thing' in output:
        email_sender()





def email_sender():

sender = 'sender@sender.com'
receivers = ['receiver@receiver.com']

message = """From: From Person <sender@sender.com>
To: To Person <receiver@receiver.com>
Subject: We are blending baby !

This is a test e-mail message.
"""

try:
    smtpObj = smtplib.SMTP('localhost')
    smtpObj.sendmail(sender, receivers, message)
    print "Successfully sent email"
except SMTPException:
    print "Error: unable to send email"

main()

我很困惑，请原谅任何可能错误的缩进，这只是为了这篇文章的目的。

如果代码的缩进是粘贴的，请正确缩进代码并检查代码是否有效：

def email_sender():
    sender = 'sender@sender.com'
    receivers = ['receiver@receiver.com']

    message = """From: From Person <sender@sender.com>
    To: To Person <receiver@receiver.com>
    Subject: We are blending baby !

    This is a test e-mail message.
    """

    try:
        smtpObj = smtplib.SMTP('localhost')
        smtpObj.sendmail(sender, receivers, message)
        print "Successfully sent email"
    except SMTPException:
        print "Error: unable to send email"
