Map as Query Param not working?

[pablomadoery]

Hello,

I am using Goa v3 and trying to have a MapOf(String, Float64) as a query param of a GET endpoint.

Swagger let me put a single string. I tried with different formats like {'1': 100}, but I had no sucess in the decoding stage.

Also, I tried sending a request with Python, with a similar format for that field, with no sucess.

Assuming the following design:

package design

import . "goa.design/goa/v3/dsl"

var _ = Service("svc", func() {
    Method("usemap", func() {
        Payload(func() {
            Attribute("map", MapOf(String, Float64))
        })
        HTTP(func() {
            GET("/usemap")
            Param("map")
        })
    })
})

The generated code will populate the map attribute of the payload with requests using the following query string:

http localhost/usemap?map[foo]=42&map[bar]=43

In this example the payload will be initialized with two keys foo and bar holding the value 42 and 43 respectively.

Alternatively the map itself can be used as the entire payload:

Payload(MapOf(String, Float64))

In which case all query string parameters must have float values.
