前言
时光如白驹过隙,不知不觉间已经干了7年的GIS开发了,一路走来跌跌撞撞的,跟随着时代的洪流行尸走肉般的生存着(此处省略n个字,全是感慨)
一、官方API地址
geoserver官方的api地址还是比较全的,我整理了下放到了下面
二、请求示例
以wfs查询为例做一个查询的示例
TypeScript
/**
* 图层wfs查询
* @param {WfsQueryParams} obj 查询条件
* @returns 图层wfs结果
*/
export function wfsQuery(obj: WfsQueryParams) {
const { layername, cql, fid, startIndex, maxFeatures } = obj
const featureRequest: { [key: string]: string | number } = {
service: "WFS",
version: "1.0.0",
request: "GetFeature",
srsName: "EPSG:4326",
typename: layername,
outputFormat: "application/json"
}
if (fid) featureRequest.featureId = fid
if (cql) featureRequest.CQL_FILTER = cql
if (startIndex != null && startIndex !== undefined) featureRequest.startIndex = startIndex
if (maxFeatures != null && maxFeatures !== undefined) featureRequest.maxFeatures = maxFeatures
const params = new URLSearchParams()
for (const attr in featureRequest) {
params.append(attr, featureRequest[attr] as any)
}
return http.independentGet<WfsQueryResult>(`${MAPSERVER}/ows?${params.toString()}`)
}
在上述代码中封装了一个wfs查询的方法,最下面的请求的http用的是axios
三、geoserver-helper示例
geoserver-helper是专门封装的用于请求geoserver的wfs,mws、wps以及rest接口的帮助类
使用方法如下
1、安装依赖
TypeScript
# 安装依赖
npm i geoserver-helper
2、引用依赖
TypeScript
// 整体引入依赖
import geoserverHelper from 'geoserver-helper'
// 按需引入依赖
import utils from 'geoserver-helper/utils'
import wfsHelper from 'geoserver-helper/wfs'
import wpsHelper from 'geoserver-helper/wps'
import wmsHelper from 'geoserver-helper/wms'
import restHelper from 'geoserver-helper/rest'
3.使用
TypeScript
const restHelperInstance = new restHelper({
url: "http://localhost:8080/geoserver"
})
const wpsHelper = new geoserverRest.wpsHelper("/geoserver/ows",);
const wfsHelperInstance = new wfsHelper({
url: "/geoserver/wfs",
workspace: "test",
});
const wmsHelperInstance = new wmsHelper({
url: "/geoserver/wms",
workspace: "test",
});
//查询所有的图层列表
const res = await restHelperInstance.getLayerListApi()
console.log(res.layers)
//查询所有的工作空间列表
const res = await restHelperInstance.getWorkspaceListApi()
console.log(res.workspaces)
//查询所有的样式列表
restHelperInstance.getStylesListApi().then(res => {
debugger
console.log(res)
})
//查询单个图层详情
restHelperInstance.getLayerInfoApi("test:xzqh_shi").then(res => {
debugger
res.layer
console.log(res)
})
//查询单个工作空间详情
restHelperInstance.getWorkspaceInfoApi("qhd").then(res => {
debugger
console.log(res)
})
const currentLayerModifyInfo: ILayer.LayerModifyInfo = {
defaultStyle: {
name: "test:xzqh_shi",
// name: "polygon",
},
}
//修改图层信息
restHelperInstance.modifyLayerApi(
"xzqh_shi",
currentLayerModifyInfo,
"test",
).then(res => {
debugger
}).catch(e => {
debugger
})
//用post请求要素
wfsHelperInstance.GetFeatureByPost({
// "workspace": "test",
// "workspaceUri": "http://test",
"typename": "test:基本农田",
"startIndex": 0,
"maxFeatures": 10,
"cql": "type = '种植非粮食作' AND INTERSECTS (the_geom, MULTIPOLYGON(((119.149559 40.60191,119.1549 40.597565,119.176018 40.609817,119.220772 40.604893。。。))))"
}).then(res => {
debugger
console.log(res)
})
//要素查询
wfsHelperInstance.GetFeature({
propertyname: "name,gb",
typename: "qhd:xzqh_xian",
}).then(res => {
debugger
console.log(res)
})
//获取图层字段描述信息
wfsHelperInstance.DescribeFeatureType({
typeName: "topp:states",
}).then(res => {
debugger
console.log(res)
})
//获取wfs能力集合
wfsHelperInstance.GetCapabilities({
version: "1.0.0",
}).then(res => {
debugger
console.log(res)
})
//获取单属性属性表
wfsHelperInstance.GetPropertyValue({
typeNames: "topp:states",
valueReference: "STATE_NAME"
}).then(res => {
debugger
console.log(res)
})
//获取wms能量集合
wmsHelperInstance.GetCapabilities({
version: "1.0.0"
}).then(res => {
debugger
console.log(res)
})
//获取要素(多用于点选查询)
wmsHelperInstance.GetFeatureInfo({
layers: "ellip_visual:1000510942192095232",
version: "1.1.1",
bbox: "118.85559,39.47113,119.17419,39.776",
srs: "EPSG:4326"
}).then(res => {
debugger
console.log(res)
})
//获取图例
wmsHelperInstance.GetLegendGraphic({
layer: "ellip_visual:1000510942192095232",
}).then(res => {
debugger
console.log(res)
})
//获取wps能力集
wpsHelper.GetCapabilities().then(res => {
debugger
console.log(res)
})
//获取某个算子的详情信息
wpsHelper.DescribeProcess({
identifier: "JTS:buffer"
}).then(res => {
debugger
console.log(res)
})
