"将传单地图层中的 json 数据加载到烧瓶模式中"

Question

我创建了获取 json 数据的 Leaflet 地图和事件：

   map.on('pm:create', (e) => {
      var layer = e.layer;
      var shape = layer.toGeoJSON()
      var shape_for_db = JSON.stringify(shape);
      $('#dmodal').modal('show');
      $.ajax({
          type: "POST",
          url: "{{ url_for('maps.addohl') }}",
          contentType: "application/json",
          data: JSON.stringify({shape}),
          dataType: "json"
      });
    });
