CustomAuth

[flow2010]

Hi There,
Can you please let me know how to add custom auth as part proxy pipeline. As part of auth I need to read cookie and validate jwt token and also set cookie. Where should I add middleware class file call so that it can be applied to specific route.

Option 1) Add a transform to a specific route:

reverse-proxy/testassets/ReverseProxy.Code/Startup.cs

Lines 61 to 78 in bfb6406

	.AddTransforms(transformBuilderContext =>
	{
	// For each route+cluster pair decide if we want to add transforms, and if so, which?
	// This logic is re-run each time a route is rebuilt.
	transformBuilderContext.AddPathPrefix("/prefix");
	// Only do this for routes that require auth.
	if (string.Equals("token", transformBuilderContext.Route.AuthorizationPolicy))
	{
	transformBuilderContext.AddRequestTransform(async transformContext =>
	{
	// AuthN and AuthZ will have already been completed after request routing.
	var ticket = await transformContext.HttpContext.AuthenticateAsync("token");
	var tokenService = transformContext.HttpContext.RequestServices.GetRequiredService<TokenService>();
	var token = await tokenService.GetAuthTokenAsync(ticket.Principal);
	transformContext.ProxyRequest.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);
	});

Option 2) Add a middleware that applies to all proxy routes, then check for specific route information per request.
