Java实现仿淘宝滑动验证码研究代码详解

通过下面一张图看下要实现的功能，具体详情如下所示：

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。

直接上关键代码：

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("taobao.com"))

{

if (isIndex == true)

{

isIndex = false;

taskDetailData.DetailRemark = String.Format(@http://"输入关键字""{0}""搜索商品……", taskDetailData.TaskName);

Func 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");

Systhttp://em.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 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://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);

*/

///

/// 截取整个网页

///

///

///

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：

///

/// 截取网页的一部份

///

///

/// &ltIUathXmGpU;param name="savePath">

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。
