如何使用Go解析URL中的重复参数

Question

I'm having a call from a frontend app which serializes arrays by using duplicate keys:

queryString.stringify({foo: [1, 2, 3]});
//=> 'foo=1&foo=2&foo=3'

and generates an url like:

https://endpoint?format=json&Status=Active&Status=Disabled&Status=Test

The backend is in Go and uses: https://github.com/emicklei/go-restful

How can I resolve the duplicated parameters in URL? Right now I can only get the last value.

The go code I've tried:

req.QueryParameter("CircuitStatus")
logger.Log.Debug().Msgf("CircuitStatus %v", CircuitStatus)

The logs:

{"level":"debug","time":"2019-05-13T11:43:47+03:00","message":"CircuitStatus Test"}

Answer 1

Use QueryParameters according to the code this should return []string

req.QueryParameters("CircuitStatus")
