数据服务SQL查询无法使用

0 投票
我使用iclient of leaflet数据服务SQL查询 ,也看过举例的代码发现无法查询 F12报错如下

Uncaught (in promise) TypeError: Cannot read property 'features' of undefined
    at t.<anonymous> (古树SQL - 副本 - 副本.html:36)
    at e.value (iclient9-leaflet.min.js:8)
    at t.value [as _processFailed] (iclient9-leaflet.min.js:8)
    at t.value (iclient9-leaflet.min.js:8)
    at iclient9-leaflet.min.js:8
    at iclient9-leaflet.min.js:8

但是我用地图服务查询能出来结果,但是getfeature 一定要用到数据服务的地址,无法解决我的问题,想请问一下怎么解决

<body style=" margin: 0;overflow: hidden;background: #fff;width: 100%;height:100%;position: absolute;top: 0;">
<div id="map" style="margin:0 auto;width: 100%;height: 100%"></div>
<script type="text/javascript" src="dist/include-leaflet.js"></script>
<script type="text/javascript">
    var host = window.isLocal ? window.server : "http://localhost:8090";
    var map, resultLayer,
         baseUrl = host + "/iserver/services/map-TM11/rest/maps/zongTM";
  url = host + "/iserver/services/data-TM11/rest/data",
    map = L.map('map', {
        center: {lon: 119.51, lat: 30.35},
   crs: L.CRS.EPSG4326,
        zoom:11.2
    });
    L.supermap.tiledMapLayer(baseUrl).addTo(map);
    query();

    function query() {
        var sqlParam = new SuperMap.GetFeaturesBySQLParameters({
            queryParams: {
                name: "林场古树名木_2@tm9",
                attributeFilter: "SMID>0"
            },
            datasetNames: ["tm9:林场古树名木_2"]
        });
               L.supermap
            .featureService(url)
            .getFeaturesBySQL(sqlParam, function (serviceResult) {
              resultLayer = L.geoJSON(serviceResult.result.features).addTo(map).bindPopup('SMID = 247');
            });
    }
</script>
</body>

您好!这个问题您可以先对sqlParam和resultLayer进行console.log的操作,看看里面有没有被查询的数据。
