Add an array as request parameter with Retrofit 2

Question

I'm looking for way to add an int array (e.g [0,1,3,5]) as parameter in a GET request with retrofit 2. Then, the generated url should be like this : http://server/service?array=[0,1,3,5]

How to do this ?

Answer 1

Just add it as a query param

@GET("http://server/service")
Observable<Void> getSomething(@Query("array") List<Integer> array);

You can also use int[], or Integer... as a last param;
