Get all registered routes in ASP.NET Core 3.0

Question

I'm trying to debug an issue with routes where I'm not sure what url an external app has to hit to trigger my controllers correctly. I just want to print them all out.

I found Get all registered routes in ASP.NET Core but none of the answers seem to work in Asp.net Core 3.0

I also found https://www.nuget.org/packages/AspNetCore.RouteAnalyzer, but it's for Core 2.0

Answer 1

I just want to print them all out.

So, I guess this is for debugging purposes?

In that case, this will get you started:

public HomeController(IActionDescriptorCollectionProvider provider)
{
    this.provider = provider;
}

public IActionResult Index()
{
    var urls = this.provider.ActionDescriptors.Items
        .Select(descriptor => '/' + string.Join('/', descriptor.RouteValues.Values
                                                                        .Where(v => v != null)
                                                                        .Select(c => c.ToLower())
                                                                        .Reverse()))
        .Distinct()
        .ToList();

    return Ok(urls);
}

This will return response in the following format:

[
    "/post/delete",
    "/users/index/administration",
    "/users/details/administration",
]

If you need more information, the IActionDescriptorCollectionProvider has plenty of it.
