如何将基本身份验证添加到 Mapbox 中 WMS 源上的 header

How to add basic auth to a header on a WMS source in Mapbox

我正在使用 MapBox 并添加一个 WMS 源,与此 URL https://docs.mapbox.com/mapbox-gl-js/example/wms/

中的代码几乎相同

为了方便,代码如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Add a WMS source</title>
<meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no">
<link href="https://api.mapbox.com/mapbox-gl-js/v2.3.0/mapbox-gl.css" rel="stylesheet">
<script src="https://api.mapbox.com/mapbox-gl-js/v2.3.0/mapbox-gl.js"></script>
<style>
body { margin: 0; padding: 0; }
#map { position: absolute; top: 0; bottom: 0; width: 100%; }
</style>
</head>
<body>
<div id="map"></div>
<script>
    mapboxgl.accessToken = 'pk.eyJ1IjoibWFyaWRhdGEiLCJhIjoiY2oxZXU2dzUwMDAwaDJxdGdpOGtoNWc2MyJ9.hs8kOWZetlwyMg6COnKwCg';
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/light-v10',
zoom: 8,
center: [-74.5447, 40.6892]
});
 
map.on('load', function () {
map.addSource('wms-test-source', {
'type': 'raster',
// use the tiles option to specify a WMS tile source URL
// https://docs.mapbox.com/mapbox-gl-js/style-spec/sources/
'tiles': [
'https://img.nj.gov/imagerywms/Natural2015?bbox={bbox-epsg-3857}&format=image/png&service=WMS&version=1.1.1&request=GetMap&srs=EPSG:3857&transparent=true&width=256&height=256&layers=Natural2015'
],
'tileSize': 256
});
map.addLayer(
{
'id': 'wms-test-layer',
'type': 'raster',
'source': 'wms-test-source',
'paint': {}
},
'aeroway-line'
);
});
</script>
 
</body>
</html>

我面临的挑战是,我从中获取图块的 WMS 源需要在 header.

中作为 Basic Auth 发送用户名和密码

有谁知道如何使用 Mapbox GL JS 实现此目的?

谢谢!

你可以使用transformRequest 属性 来初始化地图。 Mapbox 文档中的示例几乎就是您的用例:

var map = new mapboxgl.Map({
    container: 'map',
    center: [-122.420679, 37.772537],
    zoom: 13,
    style: style_object,
    hash: true,
    transformRequest: (url, resourceType)=> {
        if(resourceType === 'Source' && url.startsWith('http://myHost')) {
        return {
            url: url.replace('http', 'https'),
            headers: { 'my-custom-header': true},
            credentials: 'include'  // Include cookies for cross-origin requests
        }
    }
}
});

您将需要针对您的 WMS 场景稍微修改它。
