今天在网上看了踢西工作室的一篇关于.net代码获取网站Alexa排名的文章,自己也DIY了一个Alexa查询(演示地址:http://www.yuayu.com/tools/GetUrlInfo/GetUrlInfo.aspx).
<%@import Namespace =Namespace = "System.Net" %>
<script language="VB" runat="server">
Protected Sub BtnS_Click()Sub BtnS_Click(ByVal sender As Object, ByVal e As System.EventArgs)
'中国网站排名
Lbl2.Text = ChinaRank(txtUrl.Text)
LtlUrl.Text = "查询结果 : " & txtUrl.Text
End Sub
Function ChinaRank()Function ChinaRank(ByVal Url As String) As String
Dim ChinaUrl, RpStr1, RpStr2, TempStr As String
Dim n, m As Integer
ChinaUrl = "http://www.chinarank.org.cn/overview/Info.do?url=" & Url
RpStr1 = "<hr size=""1"" />" '此行不准改动
RpStr2 = "<p id=""domain"">" & Url & "</p>" '此行不准改动
Try
Dim wc As Net.WebClient = New Net.WebClient()
wc.Credentials = CredentialCache.DefaultCredentials
Dim pageData() As Byte = wc.DownloadData(ChinaUrl)
TempStr = Encoding.Default.GetString(pageData)
n = InStr(TempStr, RpStr1) - 1
TempStr = Left(TempStr, n)
'TempStr = StrReverse(TempStr)
m = Len(TempStr) - InStr(TempStr, RpStr2) - Len(RpStr2)
TempStr = Right(TempStr, m)
wc.Dispose()
Catch ex As Exception
Return ""
End Try
Return TempStr
End Function
</script>

读了一下代码,感觉蛮有意思,感觉像是以前用火车头采集器做站点采集,于是突发奇想,是不是也写一个用.net代码获取网站的ChinaRank排名.(最近好像很多人开始看重中国网站排名)
于是也整了这样的.net代码,提供给大家.
