Navigating the right URL using Aurelia in conjunction with .Net Core and an IIS web application

Running my Aurelia app under Asp MVC Core 1.0 presents a challenge when deploying to IIS. The app uses HttpClient to interact with controller actions that return JSON data. All the actions are in the Home controller, and the HttpClient is configured like this:

http.configure(config => {
        config
          .useStandardConfiguration()
          .withBaseUrl('Home/');
});

While everything works fine on localhost:55475 during development in Visual Studio, issues arise when deployed on IIS as a web application under the default website. Since the root URL becomes server.org/MyApp, calling this.http.fetch('GetData') incorrectly requests from server.org/Home/GetData instead of server.org/MyApp/Home/GetData, leading to a 404 error.

The problem lies in the fetch request ignoring the 'MyApp' portion of the URL. Although I expected the absence of a leading slash in .withBaseUrl to make the URL relative, it seems that's not the case?

Answer №1

After some troubleshooting, I discovered that the key to resolving the issue was modifying the URL in the browser address bar. Have you tried accessing server.org/MyApp/ instead of just server.org/MyApp? This simple change did the trick for me.

In order to fix the issue entirely, I had to include a base element at the beginning of the Aurelia page to specify the base URL with a trailing slash like so:

<base href="/MyApp/" />

To implement this in ASP.Net Core, I added the following line to my index.cshtml file:

<base href="@this.Url.Content("~")/" />

Alternatively, you could opt to redirect users to the full URL using a 302 response.
