纯真IP数据包含381085条,可以通过下载的查询软件将数据解压为文本格式,并将其编码改为UTF8,否则在程序中读取中文会乱码!
下面为程序执行分析IP数据并插入到Sql Server的截图:

程序通过AJAX在客户端进行数据插入实时更新:
实现代码如下:
前端页面及javascript:

复制代码代码如下:

注:j为一个自定义的javascript类库，中间包含了ajax功能的代码
后台程序我们用来接收ajax发送的Post 请求:
代码如下:

复制代码代码如下:

 
File:do.ashx?args=ImportIPData 
public void ProcessRequest(HttpContext context) 
{ 
if (context.Request.RequestType == “POST”) 
{ 
string action = context.Request["action"]; 
//提交IP数据 
if (string.IsNullOrEmpty(action) || action == “submit”) 
{ 
string dbserver = context.Request["dbserver"], tbname = context.Request["tbname"]; 
StringBuilder sb = new StringBuilder(500); 
sb.Append(“server=”).Append(dbserver).Append(“;database=”).Append(context.Request["dbname"]) 
.Append(“;uid=”).Append(context.Request["dbuid"]).Append(“;pwd=”).Append(context.Request["dbpwd"]); 
//保存数据库连接字符串及数据表名 
HttpContext.Current.Session["ip_dbconnstring"] = sb.ToString(); 
HttpContext.Current.Session["ip_tablename"] = tbname; 
//读取IP数据并缓存 
IList<string> ipList = new List<string>(); 
HttpPostedFile file = context.Request.Files[0]; 
using (StreamReader sr = new StreamReader(file.InputStream, Encoding.UTF8)) 
{ 
while (sr.Peek() != -1) 
{ 
ipList.Add(Regex.Replace(sr.ReadLine(), “//s{2,}”, ” “)); 
} 
} 
HttpRuntime.Cache.Insert(“ip_data”, ipList); 
//想客户端发送数据信息(Json格式) 
sb.Remove(0, sb.Length); 
sb.Append(“[{server:'").Append(dbserver) //服务器地址 
.Append("',count:'").Append(ipList.Count) //IP条数 
.Append("',insertNum:0") //本次插入条数 
.Append(",taskNum:0") //任务队列条数 
.Append("}]“); 
context.Session["ip_info"] = sb.ToString(); 
//触发父页面开始插入数据 
context.Response.Write(“<script>window.parent.insertIP();</script>”); 
} 
else 
{ 
using (SqlConnection conn = new SqlConnection(context.Session["ip_dbconnstring"] as string)) 
{ 
string tbname = context.Session["ip_tablename"] as string; 
//初始化,建表并返回信息 
if (action == “init”) 
{

} 
//插入数据 
else if (action == “insert”) 
{

StringBuilder sb = new StringBuilder(400); 
//默认每次插入300条 
int insertNum; 
int.TryParse(context.Request["num"], out insertNum); 
if (insertNum < 1) insertNum = 300; 
SqlCommand cmd = new SqlCommand(); 
cmd.Parameters.AddRange( 
new SqlParameter[]{ 
new SqlParameter(“@sip”,null), 
new SqlParameter(“@eip”,null), 
new SqlParameter(“@area”,null), 
new SqlParameter(“@name”,null) 
}); 
cmd.Connection = conn; 
conn.Open(); 
string[] arr; 
for (var i = 0; i <= insertNum && i < ipList.Count; i++) 
{ 
arr = ipList[i].Split(‘ ‘); 
cmd.CommandText = “if not exists(select id from ” + tbname + 
” where sip='”+arr[0]+”‘and eip='”+arr[1]+”‘) INSERT INTO ” + tbname +

sb.Remove(0, sb.Length); 
cmd.ExecuteNonQuery(); 
ipList.Remove(ipList[i]); 
} 
sb.Remove(0, sb.Length); 
sb.Append(“[{count:").Append(ipList.Count) //未插入IP的条数 
.Append(",insertNum:").Append(insertNum) 
.Append("}]“); 
context.Response.Write(sb.ToString()); 
} 
} 
} 
} 
}
