How to set cookies to WebView2 control in c#?

Question

How to set the cookies in Webview2 control in c#?

Here is how i am navigating the url into WebView2 control.
WebView.CoreWebView2.Navigate("URL Name");

I tried using the 'WebResourceRequested' event but there is no way to add headers into the request.
WebView.CoreWebView2.WebResourceRequested += CoreWebView2_WebResourceRequested;
private void WebView_NavigationStarting(object sender, CoreWebView2NavigationStartingEventArgs e)
{
strNavigationURL = e.Uri;
e.RequestHeaders.????
}

Since I have read that in some other forum that this is a known bug of WebView2, and hopefully all waiting to see that is been resolved in WebView2 SDK 1.0.674-prerelease.

But i could not find any solution in WebView2 1.0.674 -Prerelease. Can someone help me in this regard?

Since i need to pass the authorization token to this URL, Can someone help me to add the header value to the request?

Answer 1

Thank you for the details.

I am able to pass the cookies this way.

on the form constructor initialised
WebView.CoreWebView2Ready += WebView_CoreWebView2Ready1;

Then at the CoreWebView2Ready event initialized WebResourceRequested event.
private void WebView_CoreWebView2Ready1(object sender, EventArgs e)
{
WebView.CoreWebView2.AddWebResourceRequestedFilter("*", CoreWebView2WebResourceContext.All);
WebView.CoreWebView2.WebResourceRequested += CoreWebView2_WebResourceRequested;
}
Then at the CoreWebView2_WebResourceRequested event i have set the cookies
private void CoreWebView2_WebResourceRequested(object sender, CoreWebView2WebResourceRequestedEventArgs e)
{
// Set and access the header
e.Request.Headers.SetHeader("Cookie", XXXXX);
var addedDate = e.Request.Headers.GetHeader("Cookie");
}

Hope this will be useful for someone

Hi @remya Paul ,

C# is currently not supported in the Q&A forums, the supported products are listed over here https://learn.microsoft.com/en-us/answers/products (more to be added later on).

You can ask the experts in the dedicated C# forum over here:

Hi @remya Paul ,

Thank you for your feedback.

From this API Notes, which indicates HttpRequestHeaders.Add => CoreWebView2HttpRequestHeaders.SetHeader, I think you may need to change to use e.Request.Headers.SetHeader(XXXX,XXXX) to set cookies to WebView2 control.

Sincerely,
Tianyu
