NGSI10:subscribeContextRequest does not work. #10

Closed onlyindreams closed 8 years ago

onlyindreams commented 8 years ago

Hi,

I issued subscribeContextRequest to my IoT Broker but a BAD REQUEST response was returned.

(curl localhost:8060/ngsi10/subscribeContext -s -S \
    --header  'Content-Type: application/xml' --header 'Accept: application/xml' \

As far as I can see an IoT Broker's xmlSchema(Ngsi10_Operations_v08.xsd), I think ”restriction" does not have to be included in "SubscribeContextRequest".

  <xs:complexType name="SubscribeContextRequest">
    <xs:sequence>
      <xs:element name="entityIdList" type="EntityIdList" minOccurs="1" maxOccurs="1"/>
      <xs:element name="attributeList" type="AttributeList" minOccurs="0" maxOccurs="1"/>
      <xs:element name="reference" type="xs:anyType" minOccurs="1" maxOccurs="1"/>
      <xs:element name="duration" type="xs:duration" minOccurs="0" maxOccurs="1"/>
      <xs:element name="restriction" type="Restriction" minOccurs="0" maxOccurs="1"/>
      <xs:element name="notifyConditions" type="NotifyConditionList" minOccurs="0" maxOccurs="1"/>
      <xs:element name="throttling" type="xs:duration" minOccurs="0" maxOccurs="1"/>
    </xs:sequence>
  </xs:complexType>

Is this a bug??

Sorry, I had a mistake.

When I removed "restriction" in my subscription request then it worked.

(curl localhost:8060/ngsi10/subscribeContext -s -S \
    --header  'Content-Type: application/xml' --header 'Accept: application/xml' \
    -d @-) <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<subscribeContextRequest>
    <entityIdList>
        <entityId type="order_camera" isPattern="false">
            <id>order_camera1</id>            
        </entityId>
    </entityIdList>
    <attributeList>
        <attribute>resolution</attribute>
        <attribute>interval</attribute>
    </attributeList>
    <reference>http://localhost:1028/accumulate</reference>
    <duration>P1M</duration>
    <notifyConditions>
        <notifyCondition>
            <type>ONCHANGE</type>
            <condValueList>
                <condValue>resolution</condValue>
            </condValueList>
        </notifyCondition>
    </notifyConditions>
    <throttling>PT1S</throttling>
</subscribeContextRequest>
EOF

But I have another problems about subscription feature yet. I'm going to post the problem to you later as an another issue.
