大体思路是网上看来的,网上那篇文章的查询方法是先建两个页面,第一个页面是查询的一些CHECKBOX和JS,用来输入查询的域名和域名类型,第二个页面是用来向万网接口提交的页面,提交后将查询结果分析,并返回状态.其实这样子就够用了,但是原作者传值是用了SESSION的方法进行传值,而我现在需要将查询域名做成AJAX的效果,这样在两个页面之间传送SESSION时会有一点点小麻烦,所以我将代码改了改,将原来的SESSION传值改成了javascript 的POST提交方式.这样以便于我们后面AJAX程序调用.改完后仍然是两个页面,直接将改动后的代码贴出来供大家参考和改进.
域名查询页面DomainCheck.aspx
|
以下是DomainCheck.aspx的前台代码,主要是用JS来判断域名的一些合法性,然后就是将用户选择后的域名和域名后辍组织成URL向另一个查询页面DomainPost.aspx提交

以上是查询页面,下面是它的后台CS文件
|
其实什么代码也没有写,因为此页面主要是用来提交之用,我把后台几乎不用写什么代码
using System;
using System.Collections;
using System.Web;
using System.Web.UI.WebControls;
using System.Collections.Generic;
using System.Xml;
using System.Net;
using System.IO;
using System.Text.RegularExpressions;
public partial class DomainCheck : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
|
OK,我们再来看看查询页面,此页面主要是向万网的域名查询接口网址提交查询内容,将返回结果组织成我们想要的格式来返回.代码主要如下:
DomainPost.aspx 的前台代码
|
嘿嘿,其实什么代码都没有写,主要功能全是后台CS代码中完成的,前台只是显示作用
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DomainPost.aspx.cs" Inherits="DomainPost" %>

再看看它的后台代码

以下代码主要是用来完成远程提交的,

string[] ExtArry = Request["DomainTyle"].Split('.');
for (int i = 1; i < ExtArry.Length; i++)
{
domainList.Add("."+ExtArry[i]);
}
}
//显示域名查询情况：
if (domainList.Count > 1)
{
string dm = domainList[0];
string dname;
Label lbl;
for (int i = 1; i < domainList.Count; i++)

原理基本上是这样子的,沿用了原作者的写法,不同的是,原作者从SESSION中取值,而这里用REQUEST来取值,这样有利于后期的调用.查询方法为
http://qhit.me/Domainpost.aspx?action=Check&domain=qhwins&DomainTyle=.com.cn.net 这样就可以查询了,方便后期在AJAX页面中提交.
文章没有多少水平,仅写出来供大家参考,其中原作者查询万网接口的方法有待改进.这里先直接用上了,要是我有时间再更新吧.
