主题： bbox problems using wfs on "line" or "polygon" layer
收件人： [email protected]
Hi,
I send a wfs request for a layer that the geometry is "multilinestring or
muttipolygon".But the response is wrong.
The request is :
Ext.Ajax.request({
url:'http://localhost:8080/geoserver/wfs',
params:{
REQUEST: "GetFeature",
service: 'wfs',
BBOX:
106.14509703466915,34.26036477499476,114.50996194293484,39.27246983665966 ,
sortBy:'gid',
varAsync:false,
typeName: '
'ShenBuZhongLiCeXianFenBu ',
propertyName: getColumn(dataLayer[0][1]),
version: '1.0.0', //if the version is
1.1.0,I get nothing
srsName:'EPSG:4326'
},
success:function(response){
setHTML(response);
},
failure:function(){
myMask.hide();
Ext.MessageBox.show({
title:'网络异常',
msg:'连接数据库失败',
width:300,
icon:Ext.MessageBox.INFO,
buttons:Ext.MessageBox.OK,
animEl:document.body
});
}
});//ajax
The response is
{"type":"FeatureCollection",
"features":[{
"type":"Feature",
"id":"ShenBuZhongLiCeXianFenBu.4",
"geometry":{
"type":"MultiLineString",
"coordinates":[[[88.13333999995956,47.850030000305296],[89.81667999996395,47.19167000030552],[90.28472999996683,43.820850000302165],

The request's bbox is "106.145,34.260,114.509,39.272".In the bbox's
area the layer doesn't exist,so I think that the reponse should not
include information about
the layer.
But the response's bbox is "88.133,24.919,118.587,47.850",the bbox is
much bigger than the request'bbox.And I can get some information about
the layer.
The layer's srsName is "EPSG:4326" and I can get the layer's picture
in geoserver->layer Preview ->openlayers .
I have confused with the problem for one week.Who can help me? I am a
chinese,my English is very poor.I don't know if you understand me.
Please advise.
Zhao
