从Cefsharp浏览器获取HTML [英] Getting HTML from Cefsharp Browser

问题描述

我在WinForm项目中使用CefSharp v55.0。页面加载后，我想从中获取HTML代码。为此，我正在使用它：

I am using CefSharp v55.0 in my WinForm project. After the page is loaded, I want to get HTML code from it. And for that I am using this:

private void WebBrowserFrameLoadEnded(object sender, FrameLoadEndEventArgs e)
{
    if (e.Frame.IsMain)
    {
        test.ViewSource();
        test.GetSourceAsync().ContinueWith(code =>
        {
            var html = code.Result;
        });
    }
}

对于交叉检查，我也称测试。 ViewSource（）方法，以查看GetSourceAsync方法是否获取整个代码。

And for the crosscheck, I am also calling test.ViewSource() method, to see that if GetSourceAsync method is getting the whole code or not.

不幸的是，代码不同。 ViewSource正在获取整个代码，但是GetSourceAsync并没有通过页面中生成的javascript获取代码。

Unfortunetely, codes are different. ViewSource is getting the whole code, but GetSourceAsync is not getting codes by javascript generated in the page.

请引导我一种获取页面源代码的方法，例如ViewSource，或告诉我如何捕获此ViewSource方法的临时文件。

Plase lead me a way to get source code of the page like ViewSource, or tell me how to capture this ViewSource method's temp file.

干杯。

推荐答案

尝试一下，它对我有用：

Try this, it works for me:

    public void showSource()  // <<<<<<<<<<<<<<<<<<<<<<<<<< Call this function
    {
        Task ts = getSource();
    }

    private async Task getSource()
    {
        try
        {
            //
            string source = await chromeBrowser.GetBrowser().MainFrame.GetSourceAsync();
            //
            string f = Application.StartupPath + "\\currentSource.txt";
            //
            StreamWriter wr = new StreamWriter(f, false, System.Text.Encoding.Default);
            wr.Write(source);
            wr.Close();
            //
            System.Diagnostics.Process.Start(f);
            //
        }
        catch (Exception)
        {
            //Error !
        }
    }
