[tink_web] How to access the client IP in a route?

cedx · September 11, 2020, 1:29pm

The client’s IP address is available in the request object… but how do you access the request object in a route? It seems that the request object is only available in the Container.run() handler…

I think you can just inject the context into the route:

@:params(v in query)
@:get public function enumAbstractStringInQuery(v:EStr):EStr
  return v;

@:params(v in query)
@:get public function enumAbstractIntInQuery(v:EInt):EInt
  return v;

@:params(notfoo = query['foo'])
@:params(bar.baz = query['baz'])
@:get public function alias(notfoo:String, bar:{baz:String}, ctx:Context):{foo:String, baz:String, query:String}  {
  return {
    foo: notfoo,
    baz: bar.baz,
    query: @:privateAccess ctx.request.header.url.query,
  }
}

@:params(obj.foo = query['foo'])
@:params(obj.bar = header['x-bar'])
@:params(obj.baz = body['baz'])

Thanks @Michael : injecting the Context works. But note that it is necessary to specify the @:privateAccess metadata because the Context.request property is private

@:get
function someRoute(ctx: tink.web.routing.Context) {
  final ipAddress = @:privateAccess ctx.request.clientIp;
  // ... return the response
}

Maybe @back2dos or @kevinresol will be able to shed some light on this
