没什么好注意的 就防止别人用注册机注册 对帐号密码能输入的字符验证下
最好是注册后发封邮件来激活帐号
不相信用户的输入但也别把每一个用户当成敌人
我来你的网站注册个帐号 你还搞一大堆麻烦事 我肯定不再来
------解决方案--------------------
1、验证各字段是否符合设计需求,如:
Email得包含@和.;用户名不能包含特殊字符等。
2、直接使用SQL语句进行数据查询时,对加入到语句中的所有变量都进行过滤;
3、注册页面与数据库的字符集应当统一,否则UTF8转义漏洞啥的够喝一壶的;
4、密码最好使用md5+salt方式加密,即数据库中保存两个字段,password和salt,password = md5(md5(password) + salt)。salt每次变更密码都随机生成;
5、通过验证码限制机器注册,验证码不要通过Cookie形式保存在客户端,否则可重复使用,尽量使用Session或数据库,只像客户端提供一个索引或ID。
