SMTP错误：535 5.7.8 Go中的gmail不接受用户名和密码 [英] smtp error: 535 5.7.8 Username and Password not accepted for gmail in go

问题描述

我正在尝试使用此功能测试来自本地主机的应用的传出电子邮件：

I'm trying to test an app's outgoing emails from localhost using this function:

func SendContactUsForm(subject, email, body string) error {
    var err error
    from := "[e-mail]"
    pass := "somecrazypw"
    to := "[e-mail]"
    msg := "From: " + from + "\n" +
    "To: " + to + "\n" +
    "Subject: Contact form:" + subject + "\n" + body
    err = smtp.SendMail("smtp.gmail.com:587",
        smtp.PlainAuth("", from, pass, "smtp.gmail.com"),
        from, []string{to}, []byte(msg))
    if err != nil {
        log.Printf("smtp error: %s", err)
        return err
    }
    return nil
}

但我收到此错误：

send_emails.go：171：smtp错误：535 5.7.8用户名和密码不是

尽管 [e-mail] 的凭据是正确的，并且我启用了 Allow安全性较低的应用程序在 [e-mail] 上。

Despite the fact that the credentials of [e-mail] are correct and I have enabled Allow less secure apps on [e-mail].

那么这里可能出什么问题了？以及我该如何解决？

So what could be wrong here? And how can I fix it?

推荐答案

从 https://security.google.com/settings/security/apppasswords 并使用该密码。

应用密码是一种16位密码，可让应用或设备限制访问您的Google帐户，而无需泄露您的个人密码并完全访问您的Google帐户。

An App Password is a 16-digit passcode that gives an app or device restricted access to your Google Account without having to divulge your personal password and complete access to your Google Account.
