supermap iServer---ajax调用vectorTileLayer的后台接口进行要素查询

http://iserverUrl/iserver/services/数据源地址/queryResults.json?returnPostAction=true&getMethodForm=true&returnContent=true

下面这一段是重点

/queryResults.json?returnPostAction=true&getMethodForm=true&returnContent=true

采用queryResults中的get方法去进行相关查询,参数采用json的格式进行传参；

{
    "queryMode": "SpatialQuery",//查询模型
    "geometry": {
        "type": "POINT",//我这里采用了点查询
        "points": [//查询点的坐标
            {
                "x": 83.34,
                "y": 42.37
            }
        ]
    },
    "queryParameters": {
        "queryParams": [
            {
                "attributeFilter": "SMID > 0",
                "name": "xxx@xxx"
            }
        ],
        "startRecord": 0,//开始索引
        "expectCount": 1,//期待返回的要素数量
        "queryOption": "GEOMETRY"//直接返回几何数据
    },
    "spatialQueryMode": "WITHIN"//与查询点相交的元素
}

回调结果如下

{
    "recordsets": [
        {
            "datasetName": "xx@xx数据源",
            "features": [
