示例

本示例中对 WFS 服务 data-world/wfs100进行了3次 GetFeature 操作，可以执行 GET 请求，也可对 http://localhost:8090/iserver/services/data-world/wfs100 执行 POST 请求。

  1. DWithin

执行 GET 请求，在 World:Capitals 获取在（0,0）点周围10°范围内的 Feature，请求体为：

http://localhost:8090/iserver/services/data-world/wfs100?SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=World:Capitals&PROPERTYNAME=(SMY,SMX,SMUSERID,SMLIBTILEID,SMID,SMGEOMETRYSIZE,COUNTRY,CAP_POP,CAPITAL,the_geom)&Filter= (<Filter xmlns="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml"><ogc:DWithin xmlns:ogc="http://www.opengis.net/ogc"> <ogc:PropertyName>the_geom</ogc:PropertyName>    <gml:Point> <gml:coordinates>0,0</gml:coordinates> </gml:Point>    <ogc:Distance>10</ogc:Distance></ogc:DWithin></Filter>)

或执行 POST 请求，请求体为：
