获取Cookie
[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)] static extern bool InternetGetCookieEx(string pchUrl, string pchCookieName, StringBuilder pchCookieData, ref System.UInt32 pcchCookieData, int dwFlags, IntPtr lpReserved); private static string GetCookieString(string url) { uint datasize = 1024; StringBuilder cookieData = new StringBuilder((int)datasize); if (!InternetGetCookieEx(url, null, cookieData, ref datasize, 0x2000, IntPtr.Zero)) { if (datasize < 0) return null; cookieData = new StringBuilder((int)datasize); if (!InternetGetCookieEx(url, null, cookieData, ref datasize, 0x00002000, IntPtr.Zero)) return null; } return cookieData.ToString(); } private void webBrowser1_DocumentCompleted_1(object sender, WebBrowserDocumentCompletedEventArgs e) { richTextBox1.Text = string.Empty; if (cbcookie.Checked) { if (checkBox1.Checked) { richTextBox1.Text = GetCookieString(textBox1.Text.Trim()); } else { richTextBox1.Text = webBrowser1.Document.Cookie; } } }
//本事件是当每次加载完成当前页面后才会执行的 private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { //e.Url是当前加载的页面, if (e.Url.ToString().Contains("http://sufeinet.com")) { //执行操作1 } else if (e.Url.ToString().Contains("http://baidu.com")) { //执行操作2 } }
private void webBrowser1_NewWindow(object sender, CancelEventArgs e) { if (cbwindownew.Checked) { string url = ((System.Windows.Forms.WebBrowser)sender).StatusText; webBrowser1.Navigate(url); e.Cancel = true; } }
1、获取非input控件的值:
webBrowser1.Document.All["控件ID"].InnerText; 或webBrowser1.Document.GetElementById("控件ID").InnerText; 或webBrowser1.Document.GetElementById("控件ID").GetAttribute("value");
2.获取input控件的值:
webBrowser1.Document.All["控件ID"].GetAttribute("value");; 或webBrowser1.Document.GetElementById("控件ID").GetAttribute("value");
3、给输入框赋值:
//输入框 user.InnerText = "myname"; password.InnerText = "123456"; webBrowser1.Document.GetElementById("password").SetAttribute("value", "Welcome123");
4、下拉、复选、多选:
//下拉框: secret.SetAttribute("value", "question1"); //复选框 rememberme.SetAttribute("Checked", "True"); //多选框 cookietime.SetAttribute("checked", "checked");
5、根据已知有ID的元素操作没有ID的元素:
HtmlElement btnDelete = webBrowser1.Document.GetElementById(passengerId).Parent.Parent.Parent.Parent.FirstChild.FirstChild.Children[1].FirstChild.FirstChild;
根据Parent,FirstChild,Children[1]数组,多少层级的元素都能找到。
6、获取Div或其他元素的样式:
webBrowser1.Document.GetElementById("addDiv").Style;
7、直接执行页面中的脚本函数,带动态参数或不带参数都行:
Object[] objArray = new Object[1]; objArray[0] = (Object)this.labFlightNumber.Text; webBrowser1.Document.InvokeScript("ticketbook", objArray); webBrowser1.Document.InvokeScript("return false");
8、自动点击、自动提交:
HtmlElement btnAdd = doc.GetElementById("addDiv").FirstChild; btnAdd.InvokeMember("Click");
9、自动赋值,然后点击提交按钮的时候如果出现脚本错误或一直加载的问题,一般都是点击事件执行过快,这时需要借助Timer控件延迟执行提交按钮事件:
this.timer1.Enabled = true; this.timer1.Interval = 1000 * 2; private void timer1_Tick(object sender, EventArgs e) { this.timer1.Enabled = false; ClickBtn.InvokeMember("Click");//执行按扭操作 }
10、屏蔽脚本错误:
将WebBrowser控件ScriptErrorsSuppressed设置为True即可
11、自动点击弹出提示框:
private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e) { //自动点击弹出确认或弹出提示 IHTMLDocument2 vDocument = (IHTMLDocument2)webBrowser1.Document.DomDocument; vDocument.parentWindow.execScript("function confirm(str){return true;} ", "javascript"); //弹出确认 vDocument.parentWindow.execScript("function alert(str){return true;} ", "javaScript");//弹出提示 }
12.WebBrowser页面加载完毕之后,在页面中进行一些自动化操作的时候弹出框的自动点击(屏蔽)
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { //自动点击弹出确认或弹出提示 IHTMLDocument2 vDocument = (IHTMLDocument2)webBrowser1.Document.DomDocument; vDocument.parentWindow.execScript("function confirm(str){return true;} ", "javascript"); //弹出确认 vDocument.parentWindow.execScript("function alert(str){return true;} ", "javaScript");//弹出提示 //下面是你的执行操作代码 }
13、获取网页中的Iframe,并设置Iframe的src
HtmlDocument docFrame = webBrowser1.Document.Window.Frames["mainFrame"].Document; 或 HtmlDocument docFrame = webBrowser1.Document.All.Frames["mainFrame"].Document; docFrame.All["mainFrame"].SetAttribute("src", "http://www.sufeinet.com/");
14、让控件聚焦
this.webBrowser1.Select(); this.webBrowser1.Focus(); doc.All["TPL_password_1"].Focus();
