凭据问题（google smtp）

Question

我是一个非常新的Python 编码员，所以请不要对我太苛刻，谢谢。

我正在尝试使用电子邮件发送器smtplib，但在将用户凭据交给 Google 时遇到了问题。

完整代码：

mailcheck = input("This mailer is only for gmail, want to continue? (yes or no)")

# GMAIL SMTP INFORMATION

if mailcheck == "yes" or mailcheck == "Yes" or mailcheck == "y":

    smtp_server = 'smtp.gmail.com'

    port = 587

    set_server = "gmail"

else:

    print("Hey, sorry this program is only for Gmail")

#USER CREDENTIALS + RECEIVER

username = input("Google Email?")

password = input("Password?")

receiver = input("Who to send it to?")

subject = input("Subject of the email?")

econtents = input("What to put in the email?")

amount = input("Amount of emails to send?")

credentials = username + password

global d1

global d2

try:

    server = smtplib.SMTP(smtp_server, port)

    server.ehlo()

    server.starttls()

    server.login(username, password)

    print("Sending" + amount, "to", receiver)

    for i in range(1, int(amount) + 1):

        message = "From" + credentials[0] + '\nSubject' + subject + '\n' + econtents

        time.sleep(random.uniform(d1, d2))

        server.sendmail(credentials[0], receiver, message)

        print("\nEmail Sent!")

    else:

        print("Finished sending emails")

except smtplib.SMTPRecipientsRefused:

        print("Recipient refused. Invalid email address?")

except smtplib.SMTPAuthenticationError:

        print("Unable to authenticate with server. Ensure the details are correct.")

except smtplib.SMTPServerDisconnected:

        print("Server disconnected for an unknown reason.")

except smtplib.SMTPConnectError:

        print("Unable to connect to server.")

错误 ：

Unable to authenticate with server. Ensure the details are correct.

我认为这是因为credentials = username + password哪个不起作用，但我不知道如何解决它。

如果有人知道我必须改变什么才能解决这个问题，那就太好了！

您不是将这两个字符串相加，而是将它们放入一个数组中。在 Python 中，要么credentials = [username, password]或者credentials = list(username, password)但这似乎不是你的问题。当您收到 SMTPAuthenticationError 异常时，您的问题与 login() 函数有关。smtplib 文档说在运行 .starttls() 之后，您应该再次运行 .ehlo()。尝试在登录之前运行它。此外，您可以尝试在端口 465 上生成 SSL 实例。（Ctrl+F 表示 .starttls()）https://docs.python.org/2/library/smtplib.html
