我尝试使用uber team for mapbox gl编写的反应友好包装器。
我想知道是否有人使用他们的API成功渲染了geojson源的面要素。它声明<Layer/>
组件上有一个源选项属性:
sourceOptions :选项对象合并到调用GeoJSONSource方法时使用的对象
按照geoJsonSource的mapbox API,我正在尝试以下内容,并想知道还需要做些什么才能让它呈现:
import React, { Component } from 'react';
import ReactMapboxGl, { Layer, Feature } from "../node_modules/react-mapbox-gl/dist";
import logo from './logo.svg';
import './App.css';
let containerStyle = {
height: "100vh",
width: "100vw"
};
const accessToken = _removed for safety_
class App extends Component {
_polygonClicked = ({ feature }) => {
console.log("Polygon clicked", feature.geometry.coordinates);
};
render() {
return (
<div className="App">
<div className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<h2>Welcome to React</h2>
</div>
<ReactMapboxGl
style={"mapbox://styles/mapbox/streets-v8"}
center={[11.956511272000057,10.095463399000039]}
zoom={[11]}
accessToken={accessToken}
containerStyle={containerStyle}>
<Layer
type="fill"
paint={{ "fill-color": "#3bb2d0", "fill-opacity": .5 }}
id="testing"
sourceOptions={'religious',{
"type": 'geojson',
"data":'../small_poly/bridges.geojson'
}}
sourceId={'religious'}>
</Layer>
</ReactMapboxGl>
</div>
);
}
}
export default App;
&#13;
答案 0 :(得分:3)
因此,我最终在onStyleLoad
组件上使用了他们的<MapboxGl />
属性,以便访问返回原始mapbox gl API的函数。解决方案远非完美,但它确实回答了我的基本问题。我猜它有点类似逃生舱的功能。
我按照他们的文档这一行:
要使用原始Mapbox API使用onStyleLoad属性,回调函数将接收map对象作为第一个参数,然后您可以使用mapbox gl API添加自己的逻辑。
代码看起来像这样:
class App extends Component {
componentWillMount(){
this.setState({
center : [138.6000, -34.9286]
})
}
_polygonClicked = ({ feature }) => {
console.log("Polygon clicked", feature.geometry.coordinates);
};
_onStyleLoad = (map, event) => {
console.log("map", map, "event: ", event, this.refs.map)
map.addSource("16MAR13-FP-TOMNOD", {
type: 'vector',
tiles: ['https://s3.amazonaws.com/tomnod-vector-tiles/16MAR13-FP-TOMNOD/{z}/{x}/{y}']
})
map.addLayer({
"id": "16MAR13-FP-TOMNOD",
"type": "line",
"source": "16MAR13-FP-TOMNOD",
"source-layer": "16MAR13-FP-TOMNOD",
"layout": {
"visibility": "visible"
},
"paint": {},
"interactive": true
});
}
_onClick = () => {
this.setState({
center : [110,23]
})
}
render() {
return (
<div className="App">
<div className="App-header">
<img src={logo} className="App-logo" alt="logo" />
</div>
<ReactMapboxGl
style={"mapbox://styles/mapbox/streets-v8"}
center={this.state.center}
zoom={[13]}
accessToken={accessToken}
containerStyle={containerStyle}
onStyleLoad={this._onStyleLoad}
onClick={this._onClick}
ref='map'>
</ReactMapboxGl>
</div>
);
}
}
export default App
