滑动验证码研究-后续
前言（100天做了一件事）：
记得在几个月前写过一篇博客，淘宝滑动验证码研究 ，不少的园友对代码比较感兴趣。我也把源码发放给了2位比较聊的来的朋友。不过现在已经又升级了。^_^
这篇博客写了一个后记，估计当时也没什么人留意。我把这博客的后记截个图（这篇博客是3月7号写的，今天是6月27号，刚好100天）
现在我就来介绍些软件的其它功能。希望大家有所受益。
模拟人为搜索商品
在刷单的时候，不能直接拿到一个商品网址就进入购买页面吧，得模拟人为搜索。
在这一个过程中有两个难点：
1）商品列表的异步加载 ; 2）翻页并且截图;
在园子里，我就不在关公面前耍大刀了。直接上代码
i:搜索商品，并且翻页
public bool? SearchProduct(TaskDetailModel taskDetailData) { bool? result = null; bool isIndex = true; bool isList = true; WebBrowserTask.Instance.SetProperties(); WebBrowserTask.Instance.ClearDocumentCompleted(); WebBrowserTask.Instance.DocumentCompleted += (wbSenderSearch, wbESearch) => { System.Windows.Forms.WebBrowser currentWB = wbSenderSearch as System.Windows.Forms.WebBrowser; System.Windows.Forms.HtmlDocument currentDoc = currentWB.Document; mshtml.HTMLDocument currentDom = currentDoc.DomDocument as mshtml.HTMLDocument; String wbUrl = wbESearch.Url.ToString(); if (currentWB.ReadyState == System.Windows.Forms.WebBrowserReadyState.Complete) { #region 首页搜索 if (wbUrl.Contains("www.taobao.com")) { if (isIndex == true) { isIndex = false; taskDetailData.DetailRemark = String.Format(@"输入关键字""{0}""搜索商品……", taskDetailData.TaskName); Func<bool> func = () => { bool asynctag = false; System.Threading.Thread.Sleep(5000); asynctag = true; return asynctag; }; func.BeginInvoke((ar) => { bool asyncresult = func.EndInvoke(ar); if (asyncresult) { System.Windows.Forms.HtmlElement heee = currentDoc.GetElementById("J_SearchTab"); String classname = heee.GetAttribute("classname"); System.Windows.Forms.HtmlElement hitem = heee.Children[0]; System.Windows.Forms.HtmlElementCollection heclis = hitem.Children; System.Windows.Forms.HtmlElement li1 = heclis[0]; System.Windows.Forms.HtmlElement li2 = heclis[1]; System.Windows.Forms.HtmlElement li3 = heclis[2]; foreach (System.Windows.Forms.HtmlElement li in heclis) { String liclass = li.GetAttribute("classname"); if (liclass.Contains("selected")) { System.Windows.Forms.HtmlElement q = currentDoc.GetElementById("q"); System.Windows.Forms.HtmlElement btnsearch = currentDoc.GetElementById("J_TSearchForm").Children[0].Children[0]; if (q != null && btnsearch != null) { q.Focus(); q.SetAttribute("value", taskDetailData.TaskName); btnsearch.Focus(); string savePath = Path.Combine(UserData.WorkBenchDirectory, taskDetailData.TaskDetailCode, String.Format("搜索提交.jpg", "")); CaptureImage.CaptureWebPageArea(currentDom, savePath); btnsearch.InvokeMember("click"); } } } } }, null); } } #endregion 首页搜索 #region 商品列表 if (wbUrl.Contains("s.taobao.com")) { if (isList == true) { isList = false; Func<bool> func = () => { bool asynctag = false; asynctag = true; return asynctag; }; func.BeginInvoke((ar) => { bool asyncresult = func.EndInvoke(ar); if (asyncresult) { //解析每页商品 String clickProductURL = TurningAndParsePage(currentDoc, taskDetailData); result = true; } }, null); } } #endregion 商品列表 } }; //DocumentCompleted结束 System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => { WebBrowserTask.Instance.Navigate("https://www.taobao.com/"); })); for (int i = 0; i < 120; i++) { System.Threading.Thread.Sleep(1000); if (result != null) { break; } } return result; }
ii:因为每个页面都是异常加载的，选择适当的时机对网页进行截图
截取整个网页：
/* 因为包含了控件，如果在了线程里调用，必须用Invoke方法 System.Windows.Application.Current.Dispatcher.Invoke(new System.Action(() => { //htmlDoc.Window.ScrollTo(new System.Drawing.Point(5000, htmlDoc.Body.ScrollRectangle.Height)); string savePath = string.Format(@"D:\{0}.jpg", Guid.NewGuid().ToString()); CaptureImage.CaptureWebPage(webBrowserTask, savePath); }), System.Windows.Threading.DispatcherPriority.Background); */ /// <summary> /// 截取整个网页 /// </summary> /// <param name="web"></param> /// <param name="savePath"></param> public static void CaptureWebPage(System.Windows.Forms.WebBrowser web, String savePath) { Rectangle body = web.Document.Body.ScrollRectangle; Rectangle docRectangle = new Rectangle() { Location = new Point(0, 0), Size = new Size(body.Width, body.Height) }; web.Dock = DockStyle.None; web.Width = docRectangle.Width; web.Height = docRectangle.Height; Rectangle imgRectangle = docRectangle; using (Bitmap bitmap = new Bitmap(imgRectangle.Width, imgRectangle.Height)) { IViewObject ivo = web.Document.DomDocument as IViewObject; using (Graphics g = Graphics.FromImage(bitmap)) { IntPtr hdc = g.GetHdc(); ivo.Draw(1, -1, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, hdc, ref imgRectangle, ref docRectangle, IntPtr.Zero, 0); g.ReleaseHdc(hdc); } bitmap.Save(savePath, System.Drawing.Imaging.ImageFormat.Jpeg); bitmap.Dispose(); } }
截取网页的某个区域：
/// <summary> /// 截取网页的一部份 /// </summary> /// <param name="htmlDom"></param> /// <param name="savePath"></param> public static void CaptureWebPageArea(mshtml.HTMLDocument htmlDom, String savePath) { String saveDir = System.IO.Path.GetDirectoryName(savePath); if (!System.IO.Directory.Exists(saveDir)) { System.IO.Directory.CreateDirectory(saveDir); } Rectangle docRectangle = new Rectangle() { Location = new Point(0, 0), //Size = new Size(htmlDom.body.offsetWidth, htmlDom.body.offsetHeight) Size = new Size((int)System.Windows.SystemParameters.PrimaryScreenWidth, (int)System.Windows.SystemParameters.PrimaryScreenHeight) }; Rectangle imgRectangle = docRectangle; using (Bitmap bitmap = new Bitmap(imgRectangle.Width, imgRectangle.Height)) { IViewObject ivo = htmlDom as IViewObject; using (Graphics g = Graphics.FromImage(bitmap)) { IntPtr hdc = g.GetHdc(); ivo.Draw(1, -1, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, hdc, ref imgRectangle, ref docRectangle, IntPtr.Zero, 0); g.ReleaseHdc(hdc); } bitmap.Save(savePath, System.Drawing.Imaging.ImageFormat.Jpeg); bitmap.Dispose(); } }
在这代码里有很多有趣的片段。有心的朋友会发现。
总结
我整个软件已经开发完成。但是我就是不贴上网址。免得有人说我打广告。
哈哈
