7.6. Transaction 操作¶

7.6.1. 1. KVP 格式请求¶

Transaction 操作使用 KVP 格式请求目前叧支持 Delete（Insert 和 Update 必须通过 XML 格式请求发送）。Transaction 操作需要以下的参数：

参数	是否必须	默认值
VERSION	是	1.1.0
SERVICE	是	WFS
REQUEST=Transaction	是
OPERATION=Delete	是
TYPENAME	是
RELEASEACTION
FILTER
BBOX
FEATUREID

以下是一个WFS使用KVP格式的Transaction操作示例：

http://www.someserver.com/wfs?

SERVICE=WFS&

VERSION=1.1.0&

REQUEST=Transaction&

OPERATION=Delete&

TYPENAME=InWaterA_1M,BuiltUpA_1M&

FILTER=(<Filter><Within><PropertyName>InWaterA_1M/wkbGeom<PropertyName>

<gml:Envelope>

<gml:lowerCorner>10 10</gml:lowerCorner>

<gml:upperCorner>20 20</gml:upperCorner></gml:Envelope></Within>

</Filter>)(< Filter><Within><PropertyName>BuiltUpA_1M/wkbGeom

<PropertyName><gml:Envelope><gml:lowerCorner>10 10</gml:lowerCorner>

<gml:upperCorner>20,20</gml:upperCorner>

</gml:Envelope></Within></Filter>)

7.6.2. 2.XML格式请求¶

以下是一个WFS使用XML格式的Transaction操作示例：

<?xml version="1.0" ?>

<wfs:Transaction version="1.1.0" service="WFS"

handle="Transaction 01" xmlns="http://www.someserver.com/myns"

</wfs:Insert>

<!--

being collapsed into a single segment. The The filter uses an XPath

expression to reference the designation property

-->

<wfs:Update typeName="RoadL_1M">

<wfs:Property>

<wfs:Name>RoadL_1M/segment/designation</wfs:Name>

</ogc:Filter>

</wfs:Update>

<!-- Delete the feature instance BuiltUpA_1M.1013. -->

<wfs:Delete typeName="BuiltUpA_1M">

<ogc:Filter>

<ogc:GmlObjectId gml:id="BuiltUpA_1M.1013" />

</ogc:Filter>

</wfs:Delete>

</wfs:Transaction>
