 * function queryError(object){//todo};
 * @param {string} url - 服务地址。如访问World Map服务,只需将url设为:http://localhost:8090/iserver/services/map-world/rest/maps/World+Map 即可。
 * @param {Object} options - 参数。
 * @param {DataFormat} [options.format=DataFormat.GEOJSON] - 查询结果返回格式,目前支持 iServerJSON、GeoJSON、FGB 三种格式。参数格式为 "ISERVER","GEOJSON","FGB"。
 * @param {boolean} [options.crossOrigin] - 是否允许跨域请求。
 * @param {Object} [options.headers] - 请求头。
