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”)
{
SqlCommand cmd = new SqlCommand(“if not exists(select * from sysobjects where [name]='” + tbname +
“‘ and xtype='u')BEGIN CREATE TABLE ” + tbname + “(id BIGINT PRIMARY KEY IDENTITY(1,1),sip NVARCHAR(15),eip NVARCHAR(15),area NVARCHAR(80),[name] NVARCHAR(80))END”, conn);
conn.Open();
cmd.ExecuteNonQuery();
context.Response.Write(context.Session["ip_info"]);
}
//插入数据
else if (action == “insert”)
{
IList<string> ipList = HttpRuntime.Cache["ip_data"] as IList<string>;
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 +
” values(@sip,@eip,@area,@name)”;
cmd.Parameters["@sip"].Value = arr[0];
cmd.Parameters["@eip"].Value = arr[1];
cmd.Parameters["@area"].Value = arr[2];
cmd.Parameters["@name"].Value =arr.Length>=4?arr[3]:”";
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());
}
}
}
}
}
}
当处理上面的代码之后IP数据将添加到你的数据库中!总数是38万条添加时间在1个小时左右!
写入到数据库后的截图如下:
