Why are no query parameters being passed to my NancyFX module?

Question

I am running a self-hosted NancyFX web server inside of my application. Right now I have one module hosted: ``` public class MetricsModule : NancyModule { private IStorageEngine _storageEngine; public MetricsModule(IStorageEngine storageEngine) : base("/metrics") { _storageEngine = storageEngine; Get["/list"] = parameters => { var metrics = _storageEngine.GetKnownMetrics(); return Response.AsJson(metrics.ToArray()); }; Get["/query"] = parameters => { var rawStart = parameters.start; var rawEnd = parameters.end; var metrics = parameters.metrics; return Response.AsJson(0); }; } } ``` My Bootstrapper class is: ``` public class OverlookBootStrapper : DefaultNancyBootstrapper { private readonly IStorageEngine _storageEngine; public OverlookBootStrapper(IStorageEngine storageEngine) { _storageEngine = storageEngine; } protected override void ConfigureApplicationContainer(TinyIoCContainer container) { container.Register(_storageEngine); } } ``` I am trying to test it with the following test:…

Accepted Answer

The `parameters` argument to your lambda contains the route parameters you captured in the in your `Get["/query"]`. In this case nothing. See @thecodejunkie's comment for an example where there is something.

To get to the query paramters use `Request.Query`. That's also a dynamic and will contain whatever query parameters was in the request. Like so:

```
 Get["/query"] = parameters =>
    {
        var rawStart = Request.Query.start;
        var rawEnd = Request.Query.end;
        var metrics = Request.Query.metrics;

return Response.AsJson(0);
    };
```

This should work with your tests too.
