如何将数据从ASP.NET WebAPI ApiController传递到ASP.NET MVC控制器？

Question

Let's say I have the following method in my ASP.NET Web API controller:

public HttpResponseMessage Get(string code1, string code2)
{
    var response = new HttpResponseMessage(HttpStatusCode.Redirect);
    response.Headers.Location = new Uri("/", UriKind.Relative);

    return response;
}

I'd like to take the values passed in for code1 and code2 and make them available to an MVC Controller (based on the redirect above, let's just assume it's the HomeController). What is the best way to do this?

A few considerations:

• I'm not calling the WebAPI. A 3rd party site calls the endpoint and passes along code1 and code2 (it's part of an OAuth dance and is the reason I use the redirect).
• One of the values will be an access token used later for authentication. (Yes, this would eventually use HTTPS.)
• I'd like a method that's flexible enough to pass one or more values back to the MVC Controller.
• I do not necessarily need the data to live passed the session.

Thanks!

Update: Here's a look at the final code and approach.

public async Task<HttpResponseMessage> Get(string display, string code)
{
    var auth = new AuthenticationClient();
    await auth.WebServer(_consumerKey, _consumerSecret, _callbackUrl, code);

    var url = string.Format("/?token={0}&api={1}&instance_url={2}", auth.AccessToken, auth.ApiVersion,
        auth.InstanceUrl);

    var response = new HttpResponseMessage(HttpStatusCode.Redirect);
    response.Headers.Location = new Uri(url, UriKind.Relative);

    return response;
}

Not sure you have much choice other than to use a query string parameter. Path parameters don't really make much sense as there is no natural hierarchy with an auth token.
