I am trying to register a route using HTTP.jl which takes a query parameter and extract that query parameter using HTTP.URIs.queryparams but cant’ get it to work. Any help appreciated. Sample code below.  
Want to invoke a GET request of the form:  
[http://localhost:8080/api/image?search=1](http://localhost:8080/api/image?search=1)

module Resource

using Dates, HTTP, JSON3

using …Model, …Service

const ROUTER = HTTP.Router()

createImage(req) = Service.createImage(JSON3.read(req.body))::Image

HTTP.@register(ROUTER, “POST”, “/api/image”, createImage)

getImage(req) = Service.getImage(get(HTTP.URIs.queryparams(req.target), “search”, nothing))::Image

HTTP.@register(ROUTER, “GET”, “/api/image”, getImage)

function requestHandler(req)

```
obj = HTTP.handle(ROUTER, req)

return HTTP.Response(200, JSON3.write(obj))

```

end

function run()

```
HTTP.serve(requestHandler, "0.0.0.0", 8080)

```

end

end # module
