There are two problems here.
1) Your problem comes from the fact that `id` parameter name has
been special cased since early vibe.d versions to mean URL
parameter. If you enable `setLogLevel(LogLevel.debug_);` in the
very beginning of module constructor, you will see this trace:
REST route: GET /:id/something/ []
add route GET /:id/something/
It basically automatically rewrites route to prepend :id and
treats `string id` as if it was `string _id`.
2) Changing the name of string argument to `xxx` still doesn't
work and now prints this in debug trace:
REST route: GET /something/ ["xxx"]
add route GET /something/
Note the / in the end. Vibe.d does exact matching of slashes in
the version I have checked so you would have to request
http://127.0.0.1:8081/something/?xxx=a to get response.
So to make URL you want to work you'd need to do something like
this:
```
interface Api
{
@method(HTTPMethod.GET) @path("/something")
string getSomething(string xxx);
}
```
