經由過程上面一張圖看下要完成的功效，詳細概況以下所示：
如今我就來引見些軟件的其它功效。願望年夜家有所受害。
模仿工資搜刮商品
在刷單的時刻，不克不及直接拿到一個商品網址就進入購置頁面吧，得模仿工資搜刮。
在這一個進程中有兩個難點：
1）商品列表的異步加載 ; 2）翻頁而且截圖;
在園子裡，我就不在關公眼前耍年夜刀了。
直接上症結代碼：
i:搜刮商品，而且翻頁
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 首頁搜刮
if (wbUrl.Contains("www.taobao.com"))
{
if (isIndex == true)
{
isIndex = false;
taskDetailData.DetailRemark = String.Format(@"輸出症結字""{0}""搜刮商品……", 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("搜刮提交.jpg", ""));
CaptureImage.CaptureWebPageArea(currentDom, savePath);
btnsearch.InvokeMember("click");
}
}
}
}
},
null);
}
}
#endregion 首頁搜刮
#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)
{
//解析每頁商品
String clickProductURL = TurningAndParsePage(currentDoc, taskDetailData);
result = true;
}
},
null);
}
}
#endregion 商品列表
}
}; //DocumentCompleted停止
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:由於每一個頁面都是異常加載的，選擇恰當的機會對網頁停止截圖
截取全部網頁：
/*
由於包括了控件，假如在了線程裡挪用，必需用Invoke辦法
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>
/// 截取全部網頁
/// </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();
}
}
截取網頁的某個區域：
/// <summary>
/// 截取網頁的一部分
/// </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();
}
}
在這代碼裡有許多風趣的片斷。有心的同伙會發明。
