Get query string from a request

[bohdankoshyrets]

I'm trying to get the query string arguments from an URL similar to: /v2/users?direction=past&limit=20. Is there a way to get those parameters and their values inside a router to form response based on those parameters? I did try to use URLParametersReader, but it returns an empty object every time.

@bohdankoshyrets yep, there's a way you can use it, here's the example

let query = environ["QUERY_STRING"] as! String
let params = URLParametersReader.parseURLParameters(query)
let paramsDict = MultiDictionary<String, String, NoOpKeyTransform<String>>(items: params)
print(paramsDict["direction"])
print(paramsDict["limit"])

Yep, this works perfectly. Once again, thank you, @fangpenlin!
