<binding name="bdPO-HTTP" type="abs:ptPurchaseOrder">
  <httpbind:binding verb="POST"/>
  <operation name="opSubmitOrder">
  <httpbind:operation location="submit"/>
    <input>
      ...
    </input>
    <output>
      ...
    </output>
  </operation>
</binding>

Example 15.27 - The httpbind:binding and httpbind:operation extensibility elements used to bind the port type and operation, respectively.


<service name="svPurchaseOrder">
  <port name="purchaseOrder-http" binding="tns:bdPO-HTTP">
  <httpbind:address location=
    "http://actioncon.com/services/http/po/"/>
  </port>
</service>

Example 15.28 - The httpbind:address extensibility element with a location attribute indicating the point of contact for this service.


<httpbind:address location=
  "http://actioncon.com/services/http/po/"/>


<operation name="opSubmitOrder">
  <httpbind:operation location="submit"/>
  <input>
    <mimebind:content type="text/xml"/>
  </input>
  <output>
    <mimebind:content type="text/xml"/>
  </output>
</operation>

Example 15.29 - Both input and output messages are bound to the standard text/xml MIME content type.

Example 15.30 - A complete WSDL 1.1 definition of the Purchase Order service with an imported abstract description bound to HTTP only.


POST /services/http/po/status HTTP/1.1
Host: actioncon.com
Content-Type: text/xml; charset="utf-8"
  ...
<poNumber xmlns="http://actioncon.com/schema/purchasing">
  123456
</poNumber>

Example 15.31 - A simple HTTP request message sent to the Web service.


HTTP/1.1 200 OK
Content-type: application/xml
...
<status xmlns="http://actioncon.com/schema/purchasing">
  Pending
</status>

Example 15.32 - A simple HTTP response message sent by the Web service.


<binding name="bdPO-HTTP" interface="abs:ifPurchaseOrder"
  type="http://www.w3.org/ns/wsdl/http" whttp:methodDefault="POST">
  <operation ref="tns:opSubmitOrder"
    whttp:location="submit"/>
  <operation ref="opCheckOrderStatus"
    whttp:location="status" whttp:method="GET"/>
  <operation ref="opChangeOrder"
    whttp:location="change"/>
  <operation ref="opCancelOrder"
    whttp:location="cancel"/>
</binding>

Example 15.33 - A binding construct with child operation elements. Each element in this construct is extended with HTTPspecific attribute values.


<service name="svPurchaseOrder"
  interface="abs:ifPurchaseOrder">
  <endpoint name="purchaseOrder-http"
    binding="tns:bdPO-HTTP" address=
      "http://actioncon.com/services/http/po/"/>
</service>

Example 15.34 - The endpoint element sets the address to which HTTP messages can be sent.
