OpenAPI Query Array

[zZHorizonZz]

I'm trying to have GET method which should have a list of numbers as query parameters. Problem is that quarkus is not resolving this "http://localhost:8080/list?ids[]=5&ids[]=2&ids[]=3" which should be valid openapi query based on my search.

The OpenAPI specs:

"/list" : {
      "get" : {
        "tags" : [ "List Resource" ],
        "summary" : "List all resources by ids",
        "operationId" : "list_by_ids",
        "parameters" : [ {
          "name" : "ids",
          "in" : "query",
          "schema" : {
            "type" : "array",
            "items" : {
              "format" : "int64",
              "type" : "integer"
            }
          }
        } ],
        "responses" : {
          "200" : {
            "description" : "List of resources",
            "content" : {
              "application/json" : {
                "schema" : {
                  "type" : "array",
                  "items" : {
                    "$ref" : "#/components/schemas/Resource"
                  }
                }
              }
            }
          },
          "403" : {
            "description" : "Not Allowed"
          },
          "401" : {
            "description" : "Not Authorized"
          }
        },
        "security" : [ {
          "SecurityScheme" : [ ]
        } ]
      }
    },
    

The code from which this is generated:

@GET
    @Operation(operationId = "list_by_ids", summary = "List all resources by ids")
    @APIResponse(responseCode = "200", description = "List of resources",
            content = @Content(mediaType = MediaType.APPLICATION_JSON,
                    schema = @Schema(implementation = Resource.class, type = SchemaType.ARRAY)))
    public Uni<Response> getResourcesByIds(@RestQuery("ids") List<Long> ids) {
    }

@zZHorizonZz have you tried without the braces in the parameter names of the request?

"http://localhost:8080/list?ids=5&ids=2&ids=3"

This should make the parameter name match what is specified in the Java method parameter @RestQuery("ids") annotation.

@zZHorizonZz have you tried without the braces in the parameter names of the request?

Yes, I have tried that and it works. The problem is that this request is from a client which is generated based on openapi specs so I can't really edit the request itself. Although this doesn't seem like a bug, is there any way to create some sort of serializer?

[MikeEdgar]

Maybe you could try and add an "overload" of the REST method that is hidden from the OpenAPI spec?

@GET
@Operation(hidden = true)
public Uni<Response> getResourcesByIdsWithBraces(@RestQuery("ids[]") List<Long> ids) {
    return getResourcesByIds(ids);
}
