推荐答案

我们无法帮助您正确地输入用户！

如果他们输入的内容不是有效的电子邮件地址 [ ^ ]然后它将被拒绝。



尝试：

1）修剪它 - 当你将数据保存到数据库中时这样做，为什么不使用修剪版本作为实际地址？

2）验证它。查看上面的链接并检查数据。如果它无效，则不要将其保存在您的数据库中，只需向用户报告问题！

We can't help you make your users type correctly!
If what they type is not a valid email address[^] then it will be rejected.

Things to try:
1) Trim it - you do that when you save the data into your DB, so why not use the trimmed version as the actual address?
2) Validate it. Look at the link above and check the data. If it is invalid, then don't save it in your DB, just report the problem to the user!
