代码已经搞定,剩下的就是跑起来了
第一次跑起来遇到问题就是开头所说的"mail from address must be same as authorization user"
具体为什么会这样呢,我的账号密码没错啊,看了几篇博友的文章后确定是QQ邮箱密码出问题了。但是我用QQ密码登入邮箱是正常的,然后尝试开启POP/SMTP服务,发现了主要问题
QQ邮箱的POP/SMTP 服务没开启
操作步骤:
进入QQ邮箱->设置->账户->滚动到“POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务”
如果是没有开启,那就开启它
我没有开启,点击后需要发送短信,配置邮件客户端
发送短信完毕后,获得了授权码,将授权码替换我在代码中写的qq密码,然后重新跑起来,错误消失,主要是未授权问题
注意,授权码会在QQ密码或独立密码修改后而失效 ,需要重新获得。
重新运行,没有问题
问题虽然不是很大,也没有太多技术含量,但是能节省我们再次遇到这种问题,却想不起怎么解决的,回顾起来,总比重新重视要节省时间。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持服务器之家。
