Getting the Raw Query?

[mexicantexan]

How do I get access to the raw query? Is it in the context? If so, what would the key be? Or is there a way to do this in the design file? The index/order of the parameters I'm trying to get from the raw query is important, and can happen in any order so I don't think parsing them in the design file is the correct approach since I believe they'll lose their original order.

Right now I have this:

httpRequest, _ := ctx.Value({{NOT_SURE_WHAT_TO_PUT_HERE}}).(*http.Request)
rawQuery := httpRequest.URL.RawQuery

which I gathered from the following two pieces of documentation:

• https://goa.design/reference/goa/#func-contextresponse-a-name-goa-responsedata-contextresponse-a
• https://goa.design/implement/context/

Is this the right way to do this?

Hello, the PopulateRequestContext middleware inserts HTTP request fields into the request context including the raw request URI which contains the query string. Here is an example:

// ...
calcEndpoints = calc.NewEndpoints(calcSvc)
mux = goahttp.NewMuxer()
calcServer = calcsvr.New(calcEndpoints, mux, goahttp.RequestDecoder, goahttp.ResponseEncoder, nil, nil, nil)
calcSever.Use(middleware.PopulateRequestContext())
// ...

The URI can then be retrieved in the method using:

uri := ctx.Value(middleware.RequestURIKey)

Alternatively you could write your own HTTP middleware that populates the parsed query string.

Hope this helps!
