二级域名原理以及程序(2)




set rs=server.createobject("adodb.recordset")
sql="select * from dns where userid='"&uid&"'"
rs.open sql,conn,1,1
if not rs.EOF then
response.write"很抱歉,你已经申请过二级域名,每个用户只能申请一个二级域名!<br>你申请的二级域名是:http://"+rs("nowurl")
response.end
end if


set rs=server.createobject("adodb.recordset")
sql="select * from dns where nowurl='"&nowurl&"'"
rs.open sql,conn,1,1
if not rs.eof then
response.write"很抱歉,你申请的域名:http://"+nowurl+"已经被其他公司申请,请另外申请域名。"
response.end
end if

if len(nurl)>along then
response.write"很抱歉,你输入的域名太长,请重新输入"
response.end
end if

if instr(pbkey,nurl) then
response.write"很抱歉,你输入的域名因为含有敏感字而不管理员屏蔽,请重新输入。"
response.end
end if

'判断字符的合法性
if instr(nurl,"~") or instr(nurl,"`") or instr(nurl,"/") or instr(nurl,"?") or instr(nurl,">") or instr(nurl,"<") or instr(nurl,";") or instr(nurl,":") or instr(nurl,"}") or instr(nurl,"{") or instr(nurl,")") or instr(nurl,"(") or instr(nurl,"*") or instr(nurl,"&") or instr(nurl,"^") or instr(nurl,"%") or instr(nurl,".") or instr(nurl,",") or instr(nurl,"'") or instr(nurl,"~") or instr(nurl,"!") or instr(nurl,"$") then
response.write"很抱歉,你输入的域名含有非法字符,请重新输入,以下字符为非法字符:<br>~ ` / ? > < ; : } { ) ( * & ^ % $ # @ ! "
response.end
end if


set rs=server.createobject("adodb.recordset")
