Switch proxy dynamically using Chromiumfx

[raj3690]

Hello Everyone,

Could anyone help me on how to change the proxy settings dynamically in cef using Chromiumfx wrapper?
I able to change the proxy settings using commandline arguments at the time of initialization which is not useful for my current case.

I tried to change the preferences in the RequestContext like below.

Code: Select all

var browser = new ChromiumWebBrowser();
            var cfxRequestContext = browser.BrowserHost.RequestContext;

            var cfxProxyValue = CfxValue.Create();
            var cfxMode = CfxValue.Create();
            var cfxServer = CfxValue.Create();
            var cfxDictionaryValue = CfxDictionaryValue.Create();

            cfxServer.SetString("URL:PORT");
            cfxDictionaryValue.SetValue("mode", cfxMode);
            cfxDictionaryValue.SetValue("server", cfxServer);
            cfxProxyValue.SetDictionary(cfxDictionaryValue);
         //Calling this on the UI thread
            browser.InvokeOnUiThread(() =>
            {
               cfxRequestContext.SetPreference("proxy", cfxProxyValue, out var errorOut);
            });

It is not setting the values and not throwing any error; errorOut value coming null.
Referring to the link,https://bitbucket.org/chromiumembedded/cef/issues/1709/allow-configuration-of-preferences-during, I understand that proxy settings can be changed during runtime in cef, but couldn't able to find how to a do it using chromiumfx.
I have tried it similar to viewtopic.php?f=6&t=15724 but no luck.

Any help would be greatly appreciated.

Thanks,
Raj.

SetPreference can only be called on the CEF UI thread, are you sure InvokeOnUiThread executes on the CEF UI thread?

What does errorOut say?

Try calling SetPreference in a handler method that's already called on the CEF UI thread like OnAfterCreated.

Is Chromiumfx still actively being developed? Last I checked the project site was deleted. I'd be switching to a different browser.
