Geoserver跨域终极解决方案
技术标签：Geoserver跨域mbtiles太乐地图WebGIS
在其他程序调用使用Geoserver时，可能会遇到跨域
如
Access to XMLHttpRequest at 'http://localhost:8080/geoserver/gwc/service/tms/1.0.0/KylinWS:TestSC@EPSG:900913@pbf/8/203/150.pbf' from origin 'http://localhost:18189' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
以使用太乐地图WebGIS开发平台进行开发为例，
在使用太乐地图WebGIS开发平台 for Mapboxgl时，调用geoserver的MBtiles，遇到跨域的问题，导致地图看不到
Chrome中F12开发者模式中看到的错误
太乐地图mapboxgl示例页面也看不到地图
这是因为Geoserver或tomcat没有开启允许跨域访问。
两种方式发布GeoServer，分别是Jetty与Tomcat
两种方式跨域 cross origin 解决方法不同，看完继续看第三种解决方法
Jetty发布的解决方法

方法2：Tomcat发布的Geoserver跨域解决方法
To add CORS headers, I simply added to$CATALINA_HOME/conf/web.xmlthe following lines:
CorsFilter
org.apache.catalina.filters.CorsFilter
cors.allowed.origins
*
CorsFilter
/*
最后一种解决方法：
方法3：使用代理
自己写一个proxy.php,proxy.ashx,proxy.xxx
网上有许多代理的文章
跨域开启后，geoserver的矢量瓦片地图地图可以访问了

顺便分享一下太乐地图WebGIS开发平台访问geoserver的mbtiles的代码
