DD4T 2 with CIL: Page Not found on startup

Question

I am experimenting with DD4T 2. I'm getting the the latest alphas of everything from NuGet, and I've selected Autofac as my DI system.

When I start the application with a request for /, I get an exception, which appears to be thrown from the following code in TridionControllerBase.

[HandleError]
public virtual ActionResult Page(string url)
{
    url = AddWelcomePageToUrl(url);
    IPage page = GetPage(url);
    if (page == null) { throw new HttpException(404, "Page cannot be found"); }
    return View(GetViewName(page), page);
}

In the broker database, my root page is index.aspx. I have tried adding a DD4T.WelcomeFile appSetting, but this doesn't help. My debugging session is a bit iffy, but it's fairly clear that page is evaluating to null. (url is already null by the time my PageController gets invoked.) What might be the cause of this, and how can I further investigate?

Answer 1

It turned out that the problem was with connecting to the content service. I had configured the discovery service url in my web.config, but it turns out that you need various oauth-client- settings as well.

I also needed to specify DD4T.WelcomeFile and DD4T.PublicationId. Here is the relevant part of my web.config

<add key="DD4T.WelcomeFile" value="index.aspx" />
<add key="DD4T.PublicationId" value="15" />
<add key="discovery-service-uri" value="http://dd4t.local:8082/discovery.svc" />
<add key="cid-service-proxy-pattern" value="/cid*" />
<add key="service-caching" value="false" />
<add key="service-caching-expiration" value="60" />
<add key="oauth-enabled" value="true" />
<add key="oauth-client-id" value="cduser" />
<add key="oauth-client-secret" value="CDUserP@ssw0rd" /> 

(Note that as it's my own dev server I am running the microservices with the out-of-the-box security configuration, so you don't need to worry that I'm disclosing highly secure passwords!)
