如何打造网站克隆、仿站工具（C#版）
前两天朋友叫我模仿一个网站，刚刚开始，我一个页面一个页面查看源码并复制和保存，花了我很多时间，一个字“累”，为了减轻工作量，我写了个网站“克隆工具”，一键克隆，比起人工操作，
效率提高了200%以上，精确度也大大提高，虽然网上也很多网站克隆工具，但我觉得作为一个程序员，要有点研究精神，哈哈哈，可以根据自己的需要随意编写自己需要的功能。
下面我将我写的“网站克隆工具”实现方法分享给大家，源码在文末有下载链接，有需要的朋友可以下载来玩，也可以根据自己的需要做相应的修改或优化。
一睹为快，先看看界面：

下面一步步实现程序功能：
1.新建主界面窗体（MainForm.cs）：
文章图片
2.新建模型类（UrlModel.cs）
public class UrlModel
{
public string RelatedPath { get;
set;
}
public string AbsoluteUri { get;
set;
}
public string CurrPath { get;
set;
}
public string RootPath { get;
set;
}public string Host { get;
set;
}
public int Port { get;
set;
}
public string Scheme { get;
set;
}
}
3.新建服务类（Services）
UrlParser：
public class UrlParser
{
public static UrlModel Parse(string url)
{
UrlModel model = new UrlModel();
//默认
if (url.Length < 8)
throw new Exception("url参数不正确");
else if (!url.ToLower().StartsWith("http:") && !url.ToLower().StartsWith("https:"))
throw new Exception("url格式有误");
if (url.LastIndexOf('/') < 8)
url = url + "/";
Regex reg = new Regex("(?(http|https))://(?.+?)/", RegexOptions.Singleline);
if (reg.IsMatch(url))
{
string scheme = reg.Match(url).Groups["scheme"].Value;
string host = reg.Match(url).Groups["host"].Value;
if (host.Contains(":"))
{
var aa = host.Split(':');
if (aa.Length == 2)
{
model.Host = aa[0];
model.Port = int.Parse(aa[1]);
}
}
else
{
model.Host = host;
model.Port = 80;
}int index = url.IndexOf('/', 8);
model.RelatedPath = url.Substring(index);
model.AbsoluteUri = url;
model.Scheme = scheme;
model.CurrPath = url.Substring(0, url.LastIndexOf("/"));
if (80 == model.Port)
{
model.RootPath = string.Format("{0}://{1}", model.Scheme, model.Host);
}
else
{
model.RootPath = string.Format("{0}://{1}:{2", model.Scheme, model.Host, model.Port);
}
}
else
{
throw new Exception("url解析失败!");
}return model;
}
}
WebPageService：
///
/// 网页处理服务工具
///
public class WebPageService
{
private static string[] excludekeys = { "http:", "https:", "//", "#", "javascript:", "?", "tel:", "mailto:" };
///
/// 获取所有html元素的href属性值,只获取站点本地的链接，站外的不获取
///
/// 页面的html源码
/// GetLocalHrefs(string url,string html)
{
if (string.IsNullOrEmpty(html))
return new List();
Dictionary urls = GetHrefs(url,html);
List newUrls = new List();
if (null != urls)
{
foreach (string key in urls.Keys)
{
string newkey = key.ToLower();
bool iscontained = false;
foreach (var exkey in excludekeys)
{
if (newkey.IndexOf(exkey) == 0)
{
iscontained = true;
break;
}
}if (!iscontained) {
//只获取本地路径
newUrls.Add(urls[key]);
}
}
}return newUrls;
}///
/// 获取所有html元素的src属性值,只获取站点本地的链接，站外的不获取
///
/// 页面的html源码
/// GetLocalSrcs(string url,string html)
{
if (string.IsNullOrEmpty(html))
return new List();
Dictionary urls = GetSrc(url, html);
List newUrls = new List();
if (null != urls)
{
foreach (string key in urls.Keys)
{
string newkey = key.ToLower();
bool iscontained = false;
foreach (var exkey in excludekeys)
{
if (newkey.IndexOf(exkey) == 0)
{
iscontained = true;
break;
}
}if (!iscontained)
{
//只获取本地路径
newUrls.Add(urls[key]);
}
}
}return newUrls;
}private static Dictionary GetHrefs(string url,string html)
{
if (string.IsNullOrEmpty(html))
return null;
UrlModel currUrl = UrlParser.Parse(url);
Dictionary urls = new Dictionary();
Regex reg = new Regex("href=https://www.it610.com/"(?.+?)\"", RegexOptions.IgnoreCase);
if (currUrl != null)
{
AddUrlModel(html, currUrl, urls, reg);
}return urls;
}private static Dictionary GetSrc(string url,string html)
{
if (string.IsNullOrEmpty(html))
return null;
UrlModel currUrl = UrlParser.Parse(url);
Dictionary urls = new Dictionary();
Regex reg = new Regex("(src=https://www.it610.com/"(?.+?)\"|url\\((?.+?)\\))", RegexOptions.IgnoreCase);
if (currUrl != null)
{
AddUrlModel(html, currUrl, urls, reg);
}return urls;
}private static void AddUrlModel(string html, UrlModel currUrl, Dictionary urls, Regex reg)
{
if (reg.IsMatch(html))
{
MatchCollection matchs = reg.Matches(html);
foreach (Match item in matchs)
{
try
{
string strUrl = item.Groups["Url"].Value;
UrlModel model = new UrlModel();
model.RelatedPath = strUrl;
model.CurrPath = currUrl.CurrPath;
model.RootPath = currUrl.RootPath;
model.Scheme = currUrl.Scheme;
model.Port = currUrl.Port;
model.Host = currUrl.Host;
if (strUrl.StartsWith("/"))
{
//绝对目录情况下
model.AbsoluteUri = string.Format("{0}{1}", model.RootPath, model.RelatedPath);
}
else
{
//相对目录情况下
string currPath = model.CurrPath;
int depth = 0;
string path = model.RelatedPath;
if (path.StartsWith(".."))
{
try
{
while (path.StartsWith(".."))
{
depth++;
path = path.Substring(3);
currPath = currPath.Substring(0, currPath.LastIndexOf("/"));
}model.AbsoluteUri = string.Format("{0}/{1}", currPath, path);
}
catch
{}
}
else
{
model.AbsoluteUri = string.Format("{0}/{1}", currPath, path);
}}strUrl = strUrl.Trim().ToLower();
urls.Add(strUrl, model);
}
catch
{
}
}
}
}
}
4.网页源码扒取类
public class HttpTool
{
public static string HttpGet(string url, string referer, string encoding, out string msg)
{
msg = string.Empty;
string result = string.Empty;
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
//request.ContentType = "application/x-www-form-urlencoded";
request.Accept = "text/html,application/xhtml+xml,application/xml;
q=0.9,image/webp,*/*;
q=0.8";
request.Referer = referer;
request.Method = "GET";
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1;
WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.122 Safari/537.36";
//request.Headers.Add("Accept-Language", "zh-cn");
//request.Headers.Add("Accept-Encoding", "gzip,deflate");
request.Timeout = 60000;
//一分钟HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
if (responseStream != null)
{
StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding(encoding));
result = reader.ReadToEnd();
reader.Close();
responseStream.Close();
request.Abort();
response.Close();
return result.Trim();
}
}
catch (Exception ex)
{
msg = ex.Message + ex.StackTrace;
}return result;
}public static void DownFile(string uRLAddress, string localPath, string filename)
{
WebClient client = new WebClient();
Stream str = client.OpenRead(uRLAddress);
StreamReader reader = new StreamReader(str);
byte[] mbyte = new byte[1000000];
int allmybyte = (int)mbyte.Length;
int startmbyte = 0;
while (allmybyte > 0)
{
int m = str.Read(mbyte, startmbyte, allmybyte);
if (m == 0)
{
break;
}
startmbyte += m;
allmybyte -= m;
}reader.Dispose();
str.Dispose();
string path = Path.Combine(localPath, filename);
FileStream fstr = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);
fstr.Write(mbyte, 0, startmbyte);
fstr.Flush();
fstr.Close();
}
}
5.网站克隆主类
接口：
interface IWebCloneWorker { void Start(); void Cancel(); }
实现类：
public class WebCloneWorker : IWebCloneWorker { //网站页面克隆深度(如：0-首页,1-分类页,2-详细页面) public static int depth = 0; //要克隆的网站网址 public string Url { get; set; }//克隆后，保存的路径 public string SavePath { get; set; }private BackgroundWorker backgroundWorker1 = null; public event UrlChangedEventHandler UrlChanged; public event FileSavedSuccessEventHandler FileSavedSuccess; public event FileSavedFailEventHandler FileSavedFail; public event DownloadCompletedEventHandler DownloadCompleted; public event CollectingUrlEventHandler CollectingUrl; public event CollectedUrlEventHandler CollectedUrl; public event ProgressChangedEventHandler ProgressChanged; //所有页面、文件资源地址集合 private Dictionary _Hrefs = new Dictionary(); ////// 所有页面、文件资源地址集合 ///public Dictionary Hrefs { get { return _Hrefs; } set { _Hrefs = value; } } //网站页面请求编码,默认为UTF-8 private string _Encoding = "utf-8"; //网站页面请求编码,默认为UTF-8 public string Encoding { get { return _Encoding; } set { _Encoding = value; } } public WebCloneWorker() { } public WebCloneWorker(string url,string path) { //设置网站、保存路径 this.Url = url; this.SavePath = path; if (string.IsNullOrEmpty(this.Url)) throw new Exception("请输入网址"); if (string.IsNullOrEmpty(this.SavePath)) throw new Exception("请选择要保存的目录"); backgroundWorker1 = new BackgroundWorker(); //设置报告进度更新 backgroundWorker1.WorkerReportsProgress = true; backgroundWorker1.WorkerSupportsCancellation = true; //注册线程主体方法 backgroundWorker1.DoWork += backgroundWorker1_DoWork; //注册更新UI方法 backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged; //处理完毕 backgroundWorker1.RunWorkerCompleted += backgroundWorker1_RunWorkerCompleted; } void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Cancelled) { return; } if (this.DownloadCompleted != null) { DownloadCompletedEventArgs eventArgs = new DownloadCompletedEventArgs(e.Result, e.Error, e.Cancelled); this.DownloadCompleted(this, eventArgs); } } void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) { //进度回调 if (this.ProgressChanged != null) this.ProgressChanged(this, e); UrlModel model = (UrlModel)e.UserState; if (this.UrlChanged != null) { //Url改变后，回调 UrlChangedEventArgs eventArgs = new UrlChangedEventArgs(model); this.UrlChanged(this, eventArgs); } try { string dir = this.SavePath; string url = model.AbsoluteUri; string AbsolutePath = url.Substring(url.IndexOf('/', 8)); string fileName = ""; if (url.IndexOf('?') > 0) { string path = AbsolutePath.Substring(0, model.RelatedPath.IndexOf('?')); fileName = System.IO.Path.GetFileName(path); } else { fileName = System.IO.Path.GetFileName(AbsolutePath); } //默认首页 if (string.IsNullOrEmpty(fileName) || fileName.IndexOf(".") < 0) { fileName = "index.html"; if (!AbsolutePath.EndsWith("/")) AbsolutePath = AbsolutePath + "/"; } fileName = System.Web.HttpUtility.UrlDecode(fileName); string localPath = string.Format("{0}{1}", dir, System.IO.Path.GetDirectoryName(AbsolutePath)); if (!System.IO.Directory.Exists(localPath)) { System.IO.Directory.CreateDirectory(localPath); } //判断文件是否存在，存在不再下载 string path2 = Path.Combine(localPath, fileName); if (File.Exists(path2)) { return; } //下载网页、图片、资源文件HttpTool.DownFile(url, localPath, fileName); //保存成功后，回调 if (this.FileSavedSuccess != null) { FileSavedSuccessEventArgs eventArgs = new FileSavedSuccessEventArgs(model); this.FileSavedSuccess(this, eventArgs); } } catch (Exception ex) { //保存失败后，回调 if (this.FileSavedFail != null) { FileSavedFailEventArgs eventArgs = new FileSavedFailEventArgs(ex); this.FileSavedFail(this, eventArgs); } } } void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { //获取资源GetResource(); int index = 1; if (this.Hrefs.Keys.Count > 0) { foreach (var k in this.Hrefs.Keys) { //取消操作 if (backgroundWorker1.CancellationPending) { e.Cancel = true; return; } backgroundWorker1.ReportProgress(index, this.Hrefs[k]); index++; //挂起当前线程200毫秒 Thread.Sleep(200); } } } public void Start() { if (this.backgroundWorker1.IsBusy) return; this.backgroundWorker1.RunWorkerAsync(); } public void Cancel() { if (this.backgroundWorker1.CancellationPending) return; this.backgroundWorker1.CancelAsync(); } private void GetResource() { string url = this.Url; string referer = this.Url; string msg = ""; string html = HttpTool.HttpGet(url, referer, this.Encoding, out msg); //收集页面链接 GetHrefs(0, url, html); //收集完毕 if (null != CollectedUrl) { UrlModel urlModel = new UrlModel(); CollectedUrlEventArgs eventArgs = new CollectedUrlEventArgs(urlModel); this.CollectedUrl(this, eventArgs); } } private void GetHrefs(int level,string url,string html) { #region 添加当前页 UrlModel currUrl = UrlParser.Parse(url); try { //取消 if (backgroundWorker1.CancellationPending) return; this.Hrefs.Add(currUrl.RelatedPath, currUrl); //收集回调 if (null != CollectingUrl) { CollectingUrlEventArgs eventArgs = new CollectingUrlEventArgs(currUrl); this.CollectingUrl(this, eventArgs); } } catch { } #endregion //获取相关链接(含有href属性的) Listlist1 = WebPageService.GetLocalHrefs(url,html); //获取图片，文件等资源文件(含有src属性的) List listSrcs = WebPageService.GetLocalSrcs(url,html); #region 获取当级资源文件 if (listSrcs != null) { for (int i = 0; i < listSrcs.Count; i++) { UrlModel urlModel = listSrcs[i]; try { //取消 if (backgroundWorker1.CancellationPending) return; this.Hrefs.Add(urlModel.RelatedPath, urlModel); //收集回调 if (null != CollectingUrl) { CollectingUrlEventArgs eventArgs = new CollectingUrlEventArgs(urlModel); this.CollectingUrl(this, eventArgs); } } catch { } } } #endregion #region 获取子级页面资源 //获取第二级 if (list1 != null) { for (int i = 0; i < list1.Count; i++) { UrlModel urlModel = list1[i]; try { //取消 if (backgroundWorker1.CancellationPending) return; this.Hrefs.Add(urlModel.RelatedPath, urlModel); //收集回调 if (null != CollectingUrl) { CollectingUrlEventArgs eventArgs = new CollectingUrlEventArgs(urlModel); this.CollectingUrl(this, eventArgs); } } catch { } string msg = ""; html = HttpTool.HttpGet(urlModel.AbsoluteUri, urlModel.AbsoluteUri, this.Encoding, out msg); #region 获取子级资源文件 /* * 获取二级资源文件 * */ listSrcs = WebPageService.GetLocalSrcs(urlModel.AbsoluteUri, html); //资源文件 if (listSrcs != null) { for (int j = 0; j < listSrcs.Count; j++) { UrlModel urlModel2 = listSrcs[j]; try { //取消 if (backgroundWorker1.CancellationPending) return; this.Hrefs.Add(urlModel2.RelatedPath, urlModel2); //收集回调 if (null != CollectingUrl) { CollectingUrlEventArgs eventArgs = new CollectingUrlEventArgs(urlModel2); this.CollectingUrl(this, eventArgs); } } catch { } //挂起线程20毫秒 Thread.Sleep(20); } } #endregion //挂起线程20毫秒 Thread.Sleep(20); //到达指定深度后，退出 if (level >= depth) return; //递归 GetHrefs(level + 1, urlModel.AbsoluteUri, html); } } #endregion } }
6.一些事件、委托类：
public delegate void UrlChangedEventHandler(object sender, UrlChangedEventArgs e); public delegate void FileSavedSuccessEventHandler(object sender, FileSavedSuccessEventArgs e); public delegate void FileSavedFailEventHandler(object sender, FileSavedFailEventArgs e); public delegate void DownloadCompletedEventHandler(object sender, DownloadCompletedEventArgs e); public delegate void CollectingUrlEventHandler(object sender, CollectingUrlEventArgs e); public delegate void CollectedUrlEventHandler(object sender, CollectedUrlEventArgs e); public delegate void ProgressChangedEventHandler(object sender, ProgressChangedEventArgs e);
public class CollectedUrlEventArgs : EventArgs public class CollectingUrlEventArgs : EventArgs public class DownloadCompletedEventArgs : EventArgs public class FileSavedFailEventArgs : EventArgs public class FileSavedSuccessEventArgs : EventArgs public class UrlChangedEventArgs : EventArgs
代码有点多，各位有需要的还是下载源码查看并运行吧，由于赶时间，没时间仔细测试程序的各个功能，难免有不足的地方。
