error opening ui

Hi, I just added the rc1 version to an aurelia app, configured startup and tried to open the ui and I see this

I suppose that the error is: An unhandled exception occurred while processing the request.

<div class="titleerror">NotSupportedException: Unbounded HTTP verbs for path 'api/Attivita/GetLatest/{last}'. Are you missing an HttpMethodAttribute?</div

but this is the declaration of the action inside the controller

    [Route("[action]/{last:int}")]
    [HttpGet("{last}")]
    public IEnumerable<UltimaAttivitaVm> GetLatest(int last)
    {

am I missing something?

Just figured out how to do this… By setting DocInclusionPredicate in my setup I was able to ignore methods that don’t have a specified HttpMethod.

The source code that helped me come to this conclusion: https://github.com/domaindrivendev/Swashbuckle.AspNetCore/blob/master/src/Swashbuckle.AspNetCore.SwaggerGen/Generator/SwaggerGenerator.cs#L84

My fix:

services.AddSwaggerGen(c =>
{
    c.DocInclusionPredicate((docName, apiDesc) =>
    {
        if (apiDesc.HttpMethod == null) return false;
        return true;
    });
});

Also important to note that I am using dotnet core sdk: 1.0.0-rc4-004771, swagger aspnetcore v1.

By doing this it also removes the need to set methods to protected assuming those methods don’t have httpMethod attributes on them.

So I had the same problem today and the resolution was simple… I had the following two GET attributes on the Controller Action:

[HttpGet]
[HttpGet("id/{id?}")]

While the first one is understandable to WebApi. It is not understandable to Swagger for some reason. I fixed the issue after changing it to this:

[HttpGet("")]
[HttpGet("id/{id?}")]

Hope this helps someone.
