Question

我一直在尝试在系统中的openlayers3中实现wfs-t服务。我能够看到

<wfs:FeatureCollection xmlns="http://www.opengis.net/wfs" xmlns:wfs="http://www.opengis.net/wfs" xmlns:sf="http://www.openplans.org/spearfish" xmlns:gml="http://www.opengis.net/gml" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd http://www.openplans.org/spearfish http://localhost:9999/geoserver/sf/wfs?service=WFS&version=1.0.0&request=DescribeFeatureType&typeName=sf%3AAPRoad50MMI2015">

</gml:Box>

我的带有featureID的geoserver删除的XML是：

如何在地理服务器中启用全局设置，什么是ows？如果我传递现有路径也会抛出错误，如：

GEOSERVER中我的工作空间的路径： C：\ Program Files（x86）\ GeoServer 2.11.1 \ data_dir \ workspaces \ mywork \ jktourisam WFS-t.jpg

postgislayer.html：1 XMLHttpRequest无法加载http://localhost:9999/geoserver/mywork/wfs。对预检请求的响应没有通过访问控制检查：否＆＃39;访问控制 - 允许 - 来源＆＃39;标头出现在请求的资源上。起源＆＃39; http://localhost＆＃39;因此不允许访问。响应的HTTP状态代码为403。

我尝试了很多方法，但我找不到解决方案.......

我能够在地图上查看添加的WFS矢量图层。我的代码中是否有任何参数错误？虽然我用我的地理服务器测试了WFS-T和相同的图层网址，但在那里我也无法删除并插入geoserver和postgres的功能，但我可以在地图上使用地图上的多边形，线和点要素进行绘制并能够检索功能ID？我想在我的代码中实现CQL和ECQL过滤器，请提供任何参考链接来学习。谢谢

虽然从ajax调用（POST）提醒成功的同时也无法正常工作，我认为这是因为我传递了错误的网址？这是对的吗？请指导我在geoserver中设置环境以执行wfs-t ..

您需要在容器中启用CORS。如果您将Jetty用作容器，请查看此question，如果您使用tomcat，请查看此question。
