电子邮件地址正则表达 [英] Email address regular expression
问题描述
我一直在使用此模式来验证电子邮件地址：
^（[0-9a-z] +）（[0-9a-z \.- _] +）@（[0-9a-z \。-_] +）\。（[0-9a-z] +）
但我已经最近发现用破折号的地址不会通过这个测试。
我觉得他们应该通过。
出了什么问题？

I''ve been using this pattern to verify email addresses:
^([0-9a-z]+)([0-9a-z\.-_]+)@([0-9a-z\.-_]+)\.([0-9a-z]+)
But I''ve recently discovered that addresses with a dash in them won''t
pass this test.
Seems to me they should pass.
What''s wrong?

[AZ] =从A到Z的所有字符，也许是\-可能有帮助吗？

Aaaahhhh。但破折号不需要逃脱，做到了吗？你是否建议在表达式的第一部分添加短划线？
喜欢这个？
^（[0-9a-z - ] +）（[0-9a-z \。-_] +）@（[0-9a-z \。-_] +）\。（[0-9a-z] +）
当然，这会让某人用短划线开始他们的地址，
我不确定是否允许在真实的电子邮件地址中使用。

Aaaahhhh. But a dash doesn''t need to be escaped, do it? Are you
suggesting a add a dash to the first part of the expression? Like this?
^([0-9a-z-]+)([0-9a-z\.-_]+)@([0-9a-z\.-_]+)\.([0-9a-z]+)
Of course, that would allow someone to start their address with a dash,
which I''m not certain is allowable in real email addresses.

不[0-9a-z \。-_]表示：0到9和a to z和dot to underscore？
试试[0-9a-z \ ._-]

给我发邮件包括urkxvq （有或没有引号）
主题行中的

Doesn''t [0-9a-z\.-_] mean: 0 to 9 and a to z and dot to underscore?
try [0-9a-z\._-]
