此 curl 请求返回空的方括号 []：

它是从这个网站获得的：

（在 Firefox 中）按 F12 -> 网络选项卡。按 F5 刷新并查找唯一的 POST 方法。右键单击它->复制值->复制 POST 数据。
如果双击该 POST 方法，它会在新选项卡中返回预期数据。
我不确定是否需要标题，因为这会返回相同的空括号：
curl "https://www.bathnes.gov.uk/NodeAPI/geoDataLookup/getGeoJSON/-2.8530120849609375/51.263633525637/-2.126541137695313/51.456574106519724/11" -X POST --data-raw "^[""MLYR-54335""^]"
