Question

我是一个非常新的Python编码器，所以请不要对我太苛刻，谢谢。

我正在尝试使用smtplib来创建电子邮件收发器，但是在将用户凭据交给Google时遇到了麻烦。

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.

这意味着登录过程出错。这部分的某个地方应该出错：

 #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!")

我认为是由于credentials = username + password无效，但我不知道如何解决。

如果有人知道我必须更改以解决此问题，那就太好了！

不是要添加这两个字符串，而是要将它们放入数组中。在Python中，是

credentials = [username, password]

或

credentials = list(username, password)

但这似乎不是您的问题。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，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用于.starttls（））

凭证有问题（google smtp）
