【问题描述】：

您好，我已经对此进行了搜索，但我无法弄清楚为什么这一直失败。我正在使用以下 curl 命令通过 gmail 帐户发送电子邮件。身份验证失败。

我尝试了两个帐户，一个具有应用密码的 2 因子设置，另一个仅启用了不太安全的应用。

两者都未能通过身份验证。

curl --ssl-reqd --url smtp://smtp.gmail.com:587 --mail-from myemail@gmail.com --mail-rcpt otheremail@gmail.com --user 'myemail@gmail.com:password' --cacert cacert.pem --upload-file mail.txt --TLSv1.2 --tls-max 1.2 --verbose

cacert.pem 来自这里https://curl.haxx.se/ca/cacert.pem

这是 curl 的输出

I cannot see why this is not working, I can use the app password in another app that does not use OAuth and that lets me send emails OK.

I'm new to using curl and any help will be apricated.

Thanks.
Andy.


Edit:  I have also tried this on my linuxVM and that worked fined with GMail, so I tried again in windows and still failed.  I just removed the quotes from the user field and it worked fine.

【解决方案1】：

所以正如我在编辑后的问题中提出的。我已经解决了。

--user 'myemail@gmail.com:password' 需要从中删除单引号，它现在连接并发送邮件。

希望这将在未来对其他人有所帮助。
