使用 react-leaflet 时缺少 Leaflet Map Tiles

[英]Missing Leaflet Map Tiles when using react-leaflet

我在准系统create-react-app应用程序中使用了Leaflet-react中的简单示例

问题:地图图块会渲染,但总是有 1-2 行地图图块没有渲染(变灰)。 当地图四处移动时,不同的行将开始消失。

但是,如果我要调整浏览器窗口的大小,地图会正确呈现!

问题是什么,我们如何解决?

使用react-leaflet v2.2.1, leaflet 1.4.0。 Chrome 浏览器和 Brave 浏览器也有同样的问题。

地图.js

import React, { Component } from 'react';
import { Map, TileLayer, Marker, Popup } from 'react-leaflet';

class Maps extends Component {
    constructor() {
        super();
        this.state = {
            lat: 51.505,
            lng: -0.09,
            zoom: 13
        }
    }

    render() {
        const position = [this.state.lat, this.state.lng];

        return (
            <div>
                <Map center={position} zoom={this.state.zoom}>
                    <TileLayer
                        attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
                        url='http://{s}.tile.osm.org/{z}/{x}/{y}.png'
                    />
                    <Marker position={position}>
                        <Popup>
                            <span>A pretty CSS3 popup. <br/> Easily customizable.</span>
                        </Popup>
                    </Marker>
                </Map>

            </div>

        )
    }
}

export default Maps;

索引.js

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

import './index.css';
import Maps from './containers/Maps/Maps.js';

ReactDOM.render(
    <Router>
        <div>
            <Switch>
                <Route path="/" exact component={Maps} />
            </Switch>
        </div>
    </Router>
    , document.getElementById('root'));

索引文件

.leaflet-container {
  height: 800px;
  width: 100%;
}

索引.html

您只需要将height道具传递给您的Map组件实例。 我相信您在此之后不需要这段代码:

.leaflet-container {
  height: 800px;
  width: 100%;
}

因此应该是

<Map 
    style={{ height: "100vh" }} 
    center={position} 
    zoom={this.state.zoom}>
      <TileLayer
          attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
          url='http://{s}.tile.osm.org/{z}/{x}/{y}.png' />
      <Marker position={position}>
            <Popup>
                 <span>A pretty CSS3 popup. <br/> Easily customizable.</span>
            </Popup>
      </Marker>
</Map>
