arcgis api点击查询支持不同的图层服务

import MapView from '@arcgis/core/views/MapView';
import IdentifyTask from '@arcgis/core/tasks/IdentifyTask';
import Point from '@arcgis/core/geometry/Point';
import IdentifyParameters from '@arcgis/core/rest/support/IdentifyParameters';
export const queryMap = (view: MapView, options: ClickQuerylistConfig[], mapPoint: Point) => {
    const queryLlist: Promise<any>[] = [];
    options.forEach(item => {
        const { url, sublayers } = item;
        const identTask = new IdentifyTask({
            url,
        });
        const params = new IdentifyParameters({
            geometry: mapPoint,
            tolerance: 6,
            width: view.width,
            height: view.height,
            layerIds: sublayers,
            mapExtent: view.extent,
            returnGeometry: true,
            layerOption: 'all',
            spatialReference: view.spatialReference,
            returnFieldName: true,
        });
        let res = identTask.execute(params);

        queryLlist.push(res);
    });

    return Promise.all(queryLlist);
};

mapPoint点击的位置。

ClickQuerylistConfig

interface ClickQuerylistConfig {
    name: string;
    url: string;
    sublayers: number[];
    subName?: string;
}

name图层名称，url图层地址，sublayers子图层id,subName可以不用写。

最新版的identify写法略有不同

import IdentifyParameters from '@arcgis/core/rest/support/IdentifyParameters';
import * as identify from '@arcgis/core/rest/identify';
export const queryMap = (view: MapView, options: ClickQuerylistConfig[], mapPoint: Point) => {
    const queryLlist: Promise<any>[] = [];
    options.forEach(item => {
        const { url, sublayers } = item;
        const params = new IdentifyParameters({
            geometry: mapPoint,
            tolerance: 6,
            width: view.width,
            height: view.height,
            layerIds: sublayers,
            mapExtent: view.extent,
            returnGeometry: true,
            layerOption: 'all',
            spatialReference: view.spatialReference,
            returnFieldName: true,
        });
        let res = identify.identify(url, params);

        queryLlist.push(res);
    });

    return Promise.all(queryLlist);
};
