Question

in my use case i need to write a proxy in which i can dynamically build a jira issue catching the data from the request sent to the same proxy.
In the payload of the request there is a Json object like this:
{"objId":"073456","user":"sysadmin","message":"asdas"}
From this json i want to build this jira "CreateIssue" statement:
<jira.createIssue>
<projectKey>MY PROJECT</projectKey>
<summary>Issue sent form user: USER related to object: OBJID </summary>
<description>MESSAGE</description>
<issueType>Bug</issueType>
</jira.createIssue>
where USER, OBJID and MESSAGE are picked up from the json above.
How can i do it?

Answer 1

You can use property mediator to picked up from the json above.
<property name="objId" expression="json-eval($.objId)"/>
<property name="user" expression="json-eval($.user)"/>
<property name="OBJID" expression="get-property('OBJID')"/>
<jira.createIssue>
<projectKey>MY PROJECT</projectKey>
<summary>Issue sent form user: {$ctx:user} related to object: {$ctx:objId} </summary>
<description>MESSAGE</description>
<issueType>Bug</issueType>
</jira.createIssue>

Answer 2

You can use braces to specify dynamic values and xpath or JSON path (with "json-eval") to manipulate message payload, samples :
<summary>{concat('Issue sent form user: ', json-eval($.user), ' related to object: ', json-eval($.objId)}</summary>
<summary>{concat('Issue sent form user: ', //user/text(), ' related to object: ', //objId/text()}</summary>
