C# 从Opera浏览器获取URL

我试图从Opera浏览器中获取URL，我假设它与Chrome浏览器相同，但我错了，因为它不能以这种方式工作

到目前为止，我所做的是：

    public static string GetURL(IntPtr intPtr, string programName, out string url)
    {
        string temp = null;
            if (programName.Equals("opera"))
        {
        //    // there are always multiple opera processes, so we have to loop through all of them to find the
        //    // process with a Window Handle and an automation element of name "Address and search bar"
          /*  string x = "";
            DdeClient dde = new DdeClient("opera", "WWW_GetWindowInfo");
            try
            {
                //temp := RequestData('0xFFFFFFFF');
                dde.Connect();
                string url1 = dde.Request("URL", int.MaxValue);
                string[] text = url1.Split(new string[] { "\",\"" }, StringSplitOptions.RemoveEmptyEntries);
                dde.Disconnect();
            }
            catch (Exception)
            {
                x = "failed";
             }
*/



            Process[] procsOpera = Process.GetProcessesByName("opera");
            foreach (Process opera in procsOpera)
            {
                // the chrome process must have a window
                if (opera.MainWindowHandle == IntPtr.Zero)
               {
                      continue;
                }

                // find the automation element
                AutomationElement elm = AutomationElement.FromHandle(opera.MainWindowHandle);
                AutomationElement elmUrlBar = elm.FindFirst(TreeScope.Descendants,
                  new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));

                // if it can be found, get the value from the URL bar
                if (elmUrlBar != null)
                {
                    AutomationPattern[] patterns = elmUrlBar.GetSupportedPatterns();
                    if (patterns.Length > 0)
                    {
                        ValuePattern val = (ValuePattern)elmUrlBar.GetCurrentPattern(patterns[0]);
                        temp = val.Current.Value.ToString();
                        url = val.Current.Value.ToString();
                    }
                    else
                    {
                        temp = "";
                        url = "";
                    }
                }
                else
                {
                    temp = "";
                    url = "";
                }
            }
        }
        url = temp;
        return temp;
    }

我在NDDE客户端和自动化元素上都尝试过，但都失败了：( 我认为在自动化方面，问题就出在这方面

AutomationElement elmUrlBar = elm.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));

也许对于opera来说，它不是“地址和搜索栏”，有人能帮我解决这个问题吗

注意：chrome和opera标记了两个问题，但里面没有opera工作答案。

您可以使用它提供与UISpy相同的功能从opera UI获取AutomationId。我认为它不工作的原因是因为它在opera中的命名不同。

您可以下载

NDde dll

。添加引用后，只需将此代码复制到您想要获取url的位置即可

NDde DLL下载：

如果您想获取firefox数据，只需将

opera

更改为

firefox

DdeClient dde = new DdeClient("firefox", "WWW_GetWindowInfo");
dde.Connect();
string url = dde.Request("URL", int.MaxValue);
string[] text = url.Split(new string[] { "\",\"" }, StringSplitOptions.RemoveEmptyEntries);
dde.Disconnect();

在函数中

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;
    }
}

更改了您的功能并使其尽可能简单。适用于当前的Opera版本47.0

public static string GetOperaURL()
    {
        string url = "";

        Process[] procsOpera = Process.GetProcessesByName("opera");
        foreach (Process opera in procsOpera)
        {
            // the chrome process must have a window
            if (opera.MainWindowHandle == IntPtr.Zero)
            {
                continue;

            AutomationElement elmUrlBar = elm.FindFirst(TreeScope.Descendants,
                new PropertyCondition(AutomationElement.NameProperty, "Address field"));

            // if it can be found, get the value from the URL bar
            if (elmUrlBar == null) continue;

            AutomationPattern pattern = elmUrlBar.GetSupportedPatterns().FirstOrDefault(wr=>wr.ProgrammaticName == "ValuePatternIdentifiers.Pattern");

            if (pattern == null) continue;

            ValuePattern val = (ValuePattern)elmUrlBar.GetCurrentPattern(pattern);
            url = val.Current.Value;
            break;

非常感谢！我正在寻找的元素名为“

地址字段”

，如果将来有人需要它。非常感谢！我正在寻找的元素名为“
