Akka http client - URI encoding

Question

I am trying to invoke a Rest API using akka http client using below code.

            val httpRequest = HttpRequest(
              method  = HttpMethods.GET,


          uri ="https://example.com/customers/~/profiles/dj2bQryHPCj4IVrc48xTPD%2Bhswk%2FqNWx%2BLuUA0G2T6GLnyBVD6wC231IjgDBYJnt/preferences",

              headers = List(Accept(MediaRange(MediaTypes.`application/json`.withParams(Map("v" → "3")))),
                RawHeader("Content-Type", "application/json;v=3"),
                RawHeader("Api-Key", "XYZ")
              )
            )

Http().singleRequest(httpRequest, GatewayHelper.connectionContext)

Before the call goes out, when i check the httprequest.uri (through debugger), there is a partial uri decoding that is happening (%2B changed to +) dj2bQryHPCj4IVrc48xTPD+hswk%2FqNWx+LuUA0G2T6GLnyBVD6wC231IjgDBYJnt

Because of this the API is returning an error. Is there option where we can make akka not tamper with the URI?

Answer 1

I have not tried this but Spray and akka-http have some configuration options to modify the strictness of the URIs.

Take a look to this: http://doc.akka.io/docs/akka/2.4.10/scala/http/configuration.html#akka-http

The following parameter

Sets the strictness mode for parsing request target URIs.

 # The following values are defined: # # `strict`: RFC3986-compliant URIs are required, # a 400 response is triggered on violations # # `relaxed`: all visible 7-Bit ASCII chars are allowed # uri-parsing-mode = strict 

You might want to change it to relaxed and test again.
