mapbox-gl-js - 只为圆形mapbox gl js的边缘着色

Question

我想在交互式 map 上显示一个圆圈的轮廓(无填充)但是，mapbox-gl-js 中的绘制选项似乎仅限于填充。
https://www.mapbox.com/mapbox-gl-style-spec/#layers-circle

var styles = [{
    "id": 'points',
    "interactive": true,
    "type": "circle",
    "source": "geojson",
    "paint": {
        "circle-radius": 5,
        "circle-color": "#000
    },
    "filter": ["in", "$type", "Point"]
}, {
    "type": "line",
    "source": "geojson",
    "layout": {
      "line-cap": "round",
      "line-join": "round"
    },
    "paint": {
      "line-color": "#000",
      "line-width": 2.5
    },
    "filter": ["in", "$type", "LineString"]
}];

我错过了什么还是这不可能？

现在可以使用 circle-opacity .

例如。:

"paint": {
    "circle-opacity": 0,
    "circle-stroke-width": 1,
    "circle-stroke-color": #000
}
