问题描述

我如何在 GeckoFx 中处理下载，我正在使用版本 29 我发现了一些类似添加
事件的方法 LauncherDialog_Download(对象发送者，LauncherDialogEvent e)但是，我无法为此事件添加处理程序

How can I handle downloading in GeckoFx I'm using version 29 I've found some ways like adding event of
LauncherDialog_Download(object sender, LauncherDialogEvent e) But, I'm not able to add handler for this event

我为处理程序尝试过

LauncherDialogFactory.Register();
LauncherDialog.Download += LauncherDialog_Download;

推荐答案

表单加载后

browser.navigate("http://www.domain.com");

使用此:

LauncherDialog.Download += LauncherDialog_Download;

创建LauncherDialog_Download

Create LauncherDialog_Download

void LauncherDialog_Download(object sender, LauncherDialogEvent e)
    {
        nsILocalFile objTarget = Xpcom.CreateInstance<nsILocalFile>("@mozilla.org/file/local;1");

        using (nsAString tmp = new nsAString(@Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\temp.tmp"))
        {
            objTarget.InitWithPath(tmp);
        }

        //Save file dialog
        Stream myStream;
        SaveFileDialog saveFileDialog1 = new SaveFileDialog();

        saveFileDialog1.Filter = "All files (*.*)|*.*";
        saveFileDialog1.FilterIndex = 2;
        saveFileDialog1.RestoreDirectory = true;
        saveFileDialog1.FileName = e.Filename;

        if (saveFileDialog1.ShowDialog() == DialogResult.OK)
        {
            if ((myStream = saveFileDialog1.OpenFile()) != null)
            {
                nsIURI source = IOService.CreateNsIUri(e.Url);
                nsIURI dest = IOService.CreateNsIUri(new Uri(@saveFileDialog1.FileName).AbsoluteUri);
                nsAStringBase t = (nsAStringBase)new nsAString(System.IO.Path.GetFileName(@saveFileDialog1.FileName));

                nsIWebBrowserPersist persist = Xpcom.CreateInstance<nsIWebBrowserPersist>("@mozilla.org/embedding/browser/nsWebBrowserPersist;1");
                nsIDownloadManager DownloadMan = null;
                DownloadMan = Xpcom.CreateInstance<nsIDownloadManager>("@mozilla.org/download-manager;1");
                nsIDownload download = DownloadMan.AddDownload(0, source, dest, t, e.Mime, 0, null, (nsICancelable)persist, false);

                if (download != null)
                {
                    persist.SetPersistFlagsAttribute(2 | 32 | 16384);
                    persist.SetProgressListenerAttribute((nsIWebProgressListener)download);
                    persist.SaveURI(source, null, null, null, null, (nsISupports)dest, null);
                }

                myStream.Close();
            }
        }
    }

上面的代码还会触发saveFileDialog，因此您的程序将询问您要将文件保存在何处.

The above code also triggers saveFileDialog so your program will ask where you want to save the file.

经过测试，可以在GeckoFX 31和33上使用，但也应该在29上使用.如果没有，请从此处下载最新的GeckoFX .

Tested and working with GeckoFX 31 and 33 but should work in 29 as well. If it doesn't, download the latest GeckoFX from here.
