asp.net下將純真IP數(shù)據(jù)導(dǎo)入數(shù)據(jù)庫(kù)中的代碼

 更新時(shí)間:2011年01月29日 23:48:48   作者:  
純真IP數(shù)據(jù)庫(kù)包含最新的IP信息,通過(guò)IP我們可以查詢?cè)L問(wèn)者的來(lái)路,地理位置!但下載下來(lái)的IP數(shù)據(jù)無(wú)法被我們直接調(diào)用,所以我們需要編寫(xiě)代碼將IP寫(xiě)入到數(shù)據(jù)庫(kù)中供我們使用!
純真IP數(shù)據(jù)包含381085條,可以通過(guò)下載的查詢軟件將數(shù)據(jù)解壓為文本格式,并將其編碼改為UTF8,否則在程序中讀取中文會(huì)亂碼!
下面為程序執(zhí)行分析IP數(shù)據(jù)并插入到Sql Server的截圖:



程序通過(guò)AJAX在客戶端進(jìn)行數(shù)據(jù)插入實(shí)時(shí)更新:
實(shí)現(xiàn)代碼如下:
前端頁(yè)面及javascript:
復(fù)制代碼 代碼如下:

注:j為一個(gè)自定義的javascript類庫(kù),中間包含了ajax功能的代碼
后臺(tái)程序我們用來(lái)接收ajax發(fā)送的Post 請(qǐng)求:
代碼如下:
復(fù)制代碼 代碼如下:

File:do.ashx?args=ImportIPData
public void ProcessRequest(HttpContext context)

}
}
HttpRuntime.Cache.Insert(“ip_data”, ipList);

}
}

當(dāng)處理上面的代碼之后IP數(shù)據(jù)將添加到你的數(shù)據(jù)庫(kù)中!總數(shù)是38萬(wàn)條添加時(shí)間在1個(gè)小時(shí)左右!
寫(xiě)入到數(shù)據(jù)庫(kù)后的截圖如下:
