常用后端正则校验
单单前端校验是不安全的,所以后端的校验同样必不可少。
后端正则检验表单
public void GetValidate()
{
string email = Request["email"];
if (!Regex.IsMatch(email, @"^[\w-] (\.[\w-] )*@[\w-] (\.[\w-] ) $"))
{
Page.RegisterStartupScript("test", "<script>alert('邮箱格式不正确!');window.history.go(-1);</script>");
return;
}
string phone = Request["phone"];
if (!Regex.IsMatch(phone, @"^[1][3-8]\d{9}$"))
{
Page.RegisterStartupScript("test", "<script>alert('手机号码格式不正确!');window.history.go(-1);</script>");
return;
}
string phone = Request["phone"];
if (!Regex.IsMatch(phone, @"\d{3,4}-\d{7,8}") && !Regex.IsMatch(phone, @"^[1]\d{10}"))
{
Page.RegisterStartupScript("test", "<script>alert('电话号码格式不正确!');window.history.go(-1);</script>");
return;
}
string shopprice = Request["shopprice"];
if (!Regex.IsMatch(shopprice, @"^(([0-9]|([1-9][0-9]{0,9}))((\.[0-9]{1,2})?))$"))
{
Page.RegisterStartupScript("test", "<script>alert('金额格式不正确!');window.history.go(-1);</script>");
return;
}
string shopstore = Request["shopstore"];
if (!Regex.IsMatch(shopstore, @"^(0|[1-9]\d*)$"))
{
Page.RegisterStartupScript("test", "<script>alert('库存格式不正确!');window.history.go(-1);</script>");
return;
}
