Can't pass "hi" into DynamicDictionary

[scott-xu]

This is really a very strange thing:

this.Get["/{name?}"] = _ => this.View["Index", _.name];

When I navigate to http://localhost/abc or http://localhost/blablabla, I can get the name property as expected. But when I navigate to http://localhost/hi, I can't get it. The dynamic dictionary is empty (count equals 0)

Maybe this is an issue with your view. Using Get["/{name?}"] = _ => _.name; works fine

Still no luck.
It's easy to reproduce:

1. Create an empty web application
2. Install packages: Nancy.Owin, OwinHost
3. Create Startup.cs

public class Startup
{
    public void Configuration(IAppBuilder builder)
    {
        builder.UseNancy();
    }
}

Create MainModule.cs

public MainModule()
{
    this.Get["/{name?}"] = _ => _.name;
}

Make sure use OwinHost as server.
Press F5 and run
http://localhost:12345/abc - works as expected
http://localhost:12345/hi - doesn't work

Have you followed this? https://github.com/NancyFx/Nancy/wiki/Hosting-nancy-with-owin

[scott-xu]

Yes, I do read this.
I'm just using OwinHost.exe as the server. It works for any other words but not "hi"

@scott-xu can you put together a repro project on github that we can download and run? Thx.

[damianh]

@scott-xu "on github" thx.

Thanks @scott-xu , looking at it now.

Ok, we've gotten to the bottom of it, it's down to localisation.

One of the default conventions NAncy uses to determine the current request locale is look at the start of the path, if it matches a locale string then it strips it, sets the locale and continues. Unfortunately, as a side effect of supporting partial locals (so en rather then en-GB) that means we're stripping quite a lot of innocent two letter parameters.

I think the best solution to this is to disable that convention by default - it's simple enough to put back in.
