Hi I would like to receive `List lt Stirng gt ` in a `GET` request what s the most efficient way to do so I m currently doing like this but was hoping if I can receive List lt String gt without any manual operation ```val keywords = call request queryParameters keywords split List lt String gt ``` `GET` url will be like ` keywords=a b c`

request what's the most efficient way to do so? I'm currently doing like this but was hoping if I can receive List<String> without any manual operation

val keywords = call.request.queryParameters["keywords"]?.split(',') // List<String>?

GET

url will be like

?keywords=a,b,c

You can try to use Location and set List<String> as a param

Sorry I'm quite new and didn't understand what you just said. Can you show some small example or redirect to some doc regrading the same?

Also call.request.queryParameters.getAll("key")

Then you make a request by passing in multiple key=one&key=two...

@Big Chungus thanks but wouldn't that make things hefty for the client?

Well it's a standard http way of defining areay-like query parameters

Plus remember that client will be building query in code, so it can just use loop or map function to prefix stuff with key

ok thanks, well then I think I'll go by

getAll

method because I don't I think I should add new plugin just for such a simple use case. right?

Ktor might even support comma separated params with getAll. Give it a go, I haven't tried it myself that way

NO comma separated didn't work, but the way you mentioned worked

@Danish Ansari the client, unless is someone using curl or similar, should be using an appropriate library that will abstract away the complexity of building a URL query string
