我如何从Chrome和Firefox获得打开页面的url ?
本文关键字：url Chrome Firefox | 更新日期: 2023-09-27 18:11:33
我正在编写一个系统托盘应用程序，需要检查内部web应用程序是否打开。
我可以使用以下命令检查IE:
SHDocVw.ShellWindows shellWindows = new SHDocVw.ShellWindows();
string filename;
bool sdOpen = false;
foreach (SHDocVw.InternetExplorer ie in shellWindows)
{
filename = Path.GetFileNameWithoutExtension(ie.FullName).ToLower();
if (filename.Equals("iexplore"))
{
string[] urlParts = (ie.LocationURL.ToString()).Split('/');
string website = urlParts[2];
if (website == "myApp:8080") { sdOpen = true; };
}
}
if (sdOpen) { Console.WriteLine("App is open"); } else { Console.WriteLine("App is not open"); };
Console.ReadKey(true);
然而，一些使用该系统的用户更喜欢Chrome或Firefox。
我怎么能做同样的上面(即在浏览器中获得任何打开选项卡的url)的Chrome和Firefox?(我不打算麻烦使用其他浏览器，因为这些是我们组织中唯一使用的浏览器。)
这是针对每个浏览器的。这是主要的:
- Internet Explorer -你可以使用SHDocVw(像你一样)
- Firefox -您可以使用DDE(下面的源代码)获得URL
-
Chrome -你可以得到URL，同时枚举所有的子窗口，直到你得到控制类"Chrome_OmniboxView"，然后使用
GetWindowText文本 - Opera -你可以使用和Firefox一样的东西，但是使用"Opera"
- Safari -没有已知的方法，因为它使用自定义绘制控件
编辑:自2014年以来，Chrome发生了变化，您需要获得URL与可访问性。
使用DDE从Firefox/Opera获取URL的代码(它使用了NDDE——唯一一个好的。net DDE包装器):
//
// usage: GetBrowserURL("opera") or GetBrowserURL("firefox")
//
private string GetBrowserURL(string browser) {
try {
DdeClient dde = new DdeClient(browser, "WWW_GetWindowInfo");
dde.Connect();
string url = dde.Request("URL", int.MaxValue);
string[] text = url.Split(new string[] { "'",'"" }, StringSplitOptions.RemoveEmptyEntries);
dde.Disconnect();
return text[0].Substring(1);
} catch {
return null;
}
}
使用UIAutomation -获取FireFox和Chrome的url:
else if (browser == BrowserType.Chrome)
{
//"Chrome_WidgetWin_1"
Process[] procsChrome = Process.GetProcessesByName("chrome");
foreach (Process chrome in procsChrome)
{
// the chrome process must have a window
if (chrome.MainWindowHandle == IntPtr.Zero)
{
continue;
}
//AutomationElement elm = AutomationElement.RootElement.FindFirst(TreeScope.Children,
// new PropertyCondition(AutomationElement.ClassNameProperty, "Chrome_WidgetWin_1"));
// find the automation element
AutomationElement elm = AutomationElement.FromHandle(chrome.MainWindowHandle);
// manually walk through the tree, searching using TreeScope.Descendants is too slow (even if it's more reliable)
AutomationElement elmUrlBar = null;
try
{
// walking path found using inspect.exe (Windows SDK) for Chrome 29.0.1547.76 m (currently the latest stable)
var elm1 = elm.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Google Chrome"));
var elm2 = TreeWalker.ControlViewWalker.GetLastChild(elm1); // I don't know a Condition for this for finding :(
var elm3 = elm2.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, ""));
var elm4 = elm3.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ToolBar));
elmUrlBar = elm4.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));
}
catch
{
// Chrome has probably changed something, and above walking needs to be modified. :(
// put an assertion here or something to make sure you don't miss it
continue;
}
// make sure it's valid
if (elmUrlBar == null)
{
// it's not..
continue;
}
// elmUrlBar is now the URL bar element. we have to make sure that it's out of keyboard focus if we want to get a valid URL
if ((bool)elmUrlBar.GetCurrentPropertyValue(AutomationElement.HasKeyboardFocusProperty))
{
continue;
}
// there might not be a valid pattern to use, so we have to make sure we have one
AutomationPattern[] patterns = elmUrlBar.GetSupportedPatterns();
if (patterns.Length == 1)
{
string ret = "";
try
{
ret = ((ValuePattern)elmUrlBar.GetCurrentPattern(patterns[0])).Current.Value;
}
catch { }
if (ret != "")
{
// must match a domain name (and possibly "https://" in front)
if (Regex.IsMatch(ret, @"^(https:'/'/)?[a-zA-Z0-9'-'.]+('.[a-zA-Z]{2,4}).*$"))
{
// prepend http:// to the url, because Chrome hides it if it's not SSL
if (!ret.StartsWith("http"))
{
ret = "http://" + ret;
}
return ret;
}
}
continue;
}
}
}
else if (browser == BrowserType.Firefox)
{
AutomationElement root = AutomationElement.RootElement.FindFirst(TreeScope.Children,
new PropertyCondition(AutomationElement.ClassNameProperty, "MozillaWindowClass"));
Condition toolBar = new AndCondition(
new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ToolBar),
new PropertyCondition(AutomationElement.NameProperty, "Browser tabs"));
var tool = root.FindFirst(TreeScope.Children, toolBar);
var tool2 = TreeWalker.ControlViewWalker.GetNextSibling(tool);
var children = tool2.FindAll(TreeScope.Children, Condition.TrueCondition);
foreach (AutomationElement item in children)
{
foreach (AutomationElement i in item.FindAll(TreeScope.Children, Condition.TrueCondition))
{
foreach (AutomationElement ii in i.FindAll(TreeScope.Element, Condition.TrueCondition))
{
if (ii.Current.LocalizedControlType == "edit")
{
if (!ii.Current.BoundingRectangle.X.ToString().Contains("empty"))
{
ValuePattern activeTab = ii.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
var activeUrl = activeTab.Current.Value;
return activeUrl;
}
}
}
}
}
}
也许这段代码可以帮助一些东西;感谢BLEZ分享这个代码。我使用这段代码从firefox中捕获唯一的地址，并将它们添加到列表框中。但我认为这不是为Chrome，对吧?

下面的代码在Chrome版本58.0.3029.110下运行得很好:
请添加。net提供的Assembly中的UIAutomationClient和UIAutomationProvider的引用。
foreach (Process proc in procsChrome)
{
// the chrome process must have a window
if (proc.MainWindowHandle == IntPtr.Zero)
continue;
// to find the tabs we first need to locate something reliable - the 'New Tab' button
AutomationElement root = AutomationElement.FromHandle(proc.MainWindowHandle);
var SearchBar = root.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));
if (SearchBar != null)
return (string)SearchBar.GetCurrentPropertyValue(ValuePatternIdentifiers.ValueProperty);
}
