GetCapabilities 操作需要以下的参数：
参数 |
是否必须 |
默认值 |
SERVICE |
是 |
WFS |
REQUEST=GetCapabilities |
是 |
以下是一个 WFS 使用 KVP 格式的 GetCapabilities 操作示例：
http://www.someserver.com/wfs?
SERVICE=WFS&
REQUEST=GetCapabilities
以下是一个 WFS 使用 XML 格式的 GetCapabilities 操作示例：
<?xml version="1.0" ?>
<GetCapabilities service="WFS" xmlns="http://www.opengis.net/wfs"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.opengis.net/wfs ../wfs/1.1.0/WFS.xsd" />
以下是一个 WFS 的 GetCapabilities 操作的响应示例：
