OpenLayers：如何向地图添加图层

Question

我正在尝试使用OpenLayers显示波兰地图，并添加了我之前上传到本地地理服务器的图层，但我不知道如何在代码中连接它？

波兰地图： https://jsfiddle.net/b2L6qppd/2/

geoserver的代码：

var untiled = new ol.layer.Image({
        source: new ol.source.ImageWMS({
          ratio: 1,
          url: 'http://localhost:8080/geoserver/Geoserver/wms',
          params: {'FORMAT': format,
                   'VERSION': '1.1.1',  
                STYLES: '',
                LAYERS: 'Geoserver:ino',
          }
        })
      });
      var tiled = new ol.layer.Tile({
        visible: false,
        source: new ol.source.TileWMS({
          url: 'http://localhost:8080/geoserver/Geoserver/wms',
          params: {'FORMAT': format, 
                   'VERSION': '1.1.1',
                   tiled: true,
                STYLES: '',
                LAYERS: 'Geoserver:ino',
             tilesOrigin: 430624.45999999996 + "," + 519226.4500999991
          }
        })
      });
      var projection = new ol.proj.Projection({
          code: 'EPSG:2180',
          units: 'm',
          axisOrientation: 'neu',
          global: false
      });

请帮助
