如何检查网址是否包含Http：// [英] How Do I Check Whether An Url Consists Of Http://
问题描述
在处理基于搜索引擎优化的模块的要求时，我需要验证用户是否输入前缀 Http：// 的URL，如果他输入了全部好的...但如果他没有在 Http：// 前面加上他的网址，我的代码必须将其作为前缀添加到用户输入的网址.....我还需要检查网址是否包含< b> WWW （带前缀）...如果不是我的代码必须将此 WWW 添加到用户输入的URL中....我在这方面做了很多努力，但我可以解决它......我会更广泛地欢迎任何有关实现我的要求的建议或建议......使用java脚本...... :)
这里是我的控制器代码验证所提供网址的站点地图和机器人
In dealing a requirement of Search Engine Optimization based module i drag my self in a requirement of verifying whether user enters URL with prefix of Http:// or not...if he enters it's all ok...but if he not prefix his URL with Http:// my code must add that as prefix to entered URL by user.....and also i need to check whether URL contains WWW(with prefix)...if not my code must add this WWW to entered URL by user....I had done a really hard work on this but i can't fix it....it will be more broad welcome from my side for any advice's or suggestions towards achieving my requirement ...using java script...:)
here is my controller code to verify the sitemap and robots of the provided url
public string GetAllSemData(string givenurl)
{
var retval = string.Empty;
Seoproperties obj = new Seoproperties();
StringBuilder sb = new StringBuilder();
Dictionary<string, string> results = new Dictionary<string, string>();
#region Sitemap.xml and robots.txt
string[] names = new string[2] { "/sitemap.xml", "/robots.txt" };
sb.AppendLine("<table id='tblLists' class='gridtable' width='100%'>");
sb.AppendLine("<thead><tr>");
sb.AppendLine("<th>SEO </th>");
sb.AppendLine("<th>RESULTS</th>");
sb.AppendLine("</tr></thead>");
sb.AppendLine("<tbody>");
foreach (var item in names)
{
// string addHttp = "http://";
try
{
WebRequest request = HttpWebRequest.Create("" + givenurl + "" + item + "");
//HttpWebRequest.Create("http://" + givenurl + "" + item + "");
request.Method = "HEAD"; // Just get the document headers, not the data.
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
if (response.StatusCode == HttpStatusCode.OK)
{
retval = (item + " exists!");
if (retval == "/sitemap.xml exists!")
{
//results.Add("XML Sitemap", "Great,you site has an XML Sitemap");
sb.AppendLine("<tr>");
sb.AppendLine("<td><img src='images/1382554024_ok-green.png' alt='ok' />XML Sitemap</td>");
sb.AppendLine("<td>Great,you site has an XML Sitemap</td>");
sb.AppendLine("</tr>");
}
else
{
sb.AppendLine("<tr>");
sb.AppendLine("<td><img src='images/1382554024_ok-green.png' alt='ok' />robots.txt</td>");
sb.AppendLine("<td>Great,your site has an robots.txt file</td>");
sb.AppendLine("</tr>");
// results.Add("robots.txt", "Great,your site has an robots.txt file");
}
}
else
{
// Some other HTTP response - probably not good.min
// Check its StatusCode and handle it.
}
}
}
catch (WebException ex)
{
//HttpWebResponse webResponse = new HttpWebResponse();
HttpWebResponse webResponse = (HttpWebResponse)ex.Response;
// Determine the cause of the exception, was it 404?
if (webResponse.StatusCode == HttpStatusCode.NotFound)
{
MessageBox.Show(webResponse.StatusDescription);
retval = (item + " does'nt exists!");
if (retval == "/sitemap.xml does'nt exists!")
{
sb.AppendLine("<tr>");
sb.AppendLine("<td><img src='images/cross_circle.png' />XML Sitemap</td>");
sb.AppendLine("<td>Your Website does not have an XML Sitemap kindly create it.</td>");
sb.AppendLine("</tr>");
//results.Add("XML Sitemap", "Your Website does not have an XML Sitemap kindly create it.");
}
else

sb.AppendLine("<td><img src='images/cross_circle.png' />robots.txt</td>");
sb.AppendLine("<td>Your Website does not have Robots.txt file kindly create it.</td>");
sb.AppendLine("</tr>");
//results.Add("robots.txt", "Your Website does not have Robots.txt file kindly create it.");
}
}
else
{
// Handle differently...
retval = (ex.Message);
}
}

这里是我验证网址的JavaScript代码
here is my JavaScript code to verify the url
function SubmitUrl() {
var addHttp = 'http://';
//if (!givenurl.match(/^[]a-zA-z]+:\/\//)) {
// givenurl = 'http://' + givenurl;
//}
var givenurl = addHttp+$("#txtUrl").val();
$.ajax({
url: "Analysis/Checkfilesexitsornot?givenurl=" + givenurl,
type: 'POST',
cache: false,
data: '',
success: Checkingfilesexits,
failure: function myfunction(response) {
alert(response.d);
}
});
return false;
}
我的JavaScript代码中的
我已经获取了一个变量并将http：//添加到给定的URL变量中但我需要检查两者Http：//& WWW ..检查并添加到给定的URL ...此代码的o？p将显示有关给定URL网站的信息（标题，内容，机器人，XML站点地图，表格中给定URL的网页描述）他我已经在sb（字符串构建器）中添加了表格并添加了Seo，Results .... 2ND表是MetaData，给定URL的网站结果...
in my JavaScript code i had taken a variable and added http:// to the given URL variable but i need to check both Http:// & WWW.. to check and add to the given Url...the o?p of this code will be displaying information about given URL website (title,content,robots,XML Sitemap,description of the web page of given URL in a table)he i had taken table in sb(string builder)and adding the columns of Seo,Results....2ND table is MetaData,Results of the website of given Url...
推荐答案
（＃txtUrl）。val（）;
("#txtUrl").val();
.ajax（{
url：Analysis / Checkfilesexitsornot？givenurl =+ givenurl，
类型：'POST'，
缓存：false，
数据：''，
成功：Checkingfilesexits，
失败：函数myfunction（响应）{
alert（response.d）;
}
}）;
返回false;
}
.ajax({ url: "Analysis/Checkfilesexitsornot?givenurl=" + givenurl, type: 'POST', cache: false, data: '', success: Checkingfilesexits, failure: function myfunction(response) { alert(response.d); } }); return false; }

试试这个：
Try this :
string url=Request.URL;
if (!url.Contains("http://"))
{
}
