When a slice of primitive type is used the primitive type is added to the model

Usually primitive types are not added to the model as they are not required but if you have a []string then the string is added to the model. For instance:

package main

import (
    "net/http"

    restful "github.com/emicklei/go-restful"
    restfulspec "github.com/emicklei/go-restful-openapi"
)

func main() {
    restful.DefaultContainer.Add(webService())
    restfulConfig := restfulspec.Config{
        WebServices: restful.RegisteredWebServices(),
        APIPath:     "/apidocs.json",
    }
    restful.DefaultContainer.Add(restfulspec.NewOpenAPIService(restfulConfig))

    http.ListenAndServe(":9080", nil)
}

func webService() *restful.WebService {
    ws := new(restful.WebService)
    ws.Filter(restful.NoBrowserCacheFilter)

    ws.Path("/example").
        Produces(restful.MIME_JSON)

    ws.Route(ws.GET("readsStringSlice").
        Reads([]string{}, "List of strings").
        To(handler))

    return ws
}

func handler(req *restful.Request, resp *restful.Response) {

}

Produces:

{
 "swagger": "2.0",
 "paths": {
  "/example/readsStringSlice": {
   "get": {
    "produces": [
     "application/json"
    ],
    "operationId": "handler",
    "parameters": [
     {
      "description": "List of strings",
      "name": "body",
      "in": "body",
      "required": true,
      "schema": {
       "type": "array",
       "items": {
        "type": "string"
       }
      }
     }
    ],
    "responses": {
     "200": {
      "description": "OK"
     }
    }
   }
  }
 },
 "definitions": {
  "string": {}
 }
}

Instead of:

{
 "swagger": "2.0",
 "paths": {
  "/example/readsStringSlice": {
   "get": {
    "produces": [
     "application/json"
    ],
    "operationId": "handler",
    "parameters": [
     {
      "description": "List of strings",
      "name": "body",
      "in": "body",
      "required": true,
      "schema": {
       "type": "array",
       "items": {
        "type": "string"
       }
      }
     }
    ],
    "responses": {
     "200": {
      "description": "OK"
     }
    }
   }
  }
 }
}
