    "

    SMTP -> get_lines(): $data was ""

    SMTP -> get_lines(): $str is "235 2.0.0 Authentication successful

    "
    very long message here


    </pre>{"message":"My message.","status":1}

在某些情况下，要替换的邮件可以是</pre>{"message":"My message.","status":1}。

在这两种情况下，都应由{"message":"My message.","status":1}

替换

我正在做这样的事情msg = msg.replace(/^[<pre>]*[.]*<\/pre>{/m, '{'));

但它不起作用......需要一些帮助

Answer 1

试试这个：

msg = msg.replace(/^[\s\S]*<\/pre>({[^}]*})/, '$1')

Answer 2

只需从正则表达式中删除^，因为您不需要匹配字符串beggining。
