Вызовите вышеуказанный API следующим образом:
<payloadFactory media-type="xml">
<format>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header/>
<soapenv:Body>
<root>
<client_id>$1</client_id>
<client_secret>$2</client_secret>

</soapenv:Envelope>
</format>
<args>
<arg evaluator="xml" expression="get-property('client_id')"/>
<arg evaluator="xml" expression="get-property('client_secret')"/>
</args>
</payloadFactory>
<property name="ContentType" scope="default" type="STRING" value="application/xml"/>
<property action="remove" name="REST_URL_POSTFIX" scope="axis2"/>
<call>
<endpoint>
<http method="post" uri-template="http://localhost:8280/api/myService/getToken"/>
</endpoint>
</call>
<script language="js">
<![CDATA[ var tokenContainer = mc.getPayloadJSON();
var log = mc.getServiceLog();
mc.setProperty("Authorization_header", tokenContainer.access_token);]]>
</script>
Ответ будет
{"access_token":"LzSq94JoaUT2LwJlkEl35CXX0MdwqtUKIL8Wvi7dm4SqcSofR4xF5xBZre83MZXpHOr-Hg","expires_in":360,"token_type":"Bearer"}
В последнем посреднике сценария вы можете получить доступ к токену. выше
