Configuring Mediation Rule for NF-Mediation

Extracting the group name and the trigger point from the URLs provided below:

Note:

In rules, the "agenda-group" is used to categories the rule group using the group name and the trigger point that is provided in the URL.

URL Type 1: [http://{apiRoot}/nmediation-http/v1]

• The above URL does not have any group name or trigger point. So the rules that are without agenda-group are applicable on this.
• From the below reference rules, the rule default will be applied.

URL Type 2: [http://{apiRoot}/nmediation-http/v1/scp]

• The above URL has only the group name. So the rules that are under the agenda-group scp is applicable.
• From the below reference rules, the rule scp-rule-header-1 will be applied.

URL Type 3: [http://{apiRoot}/nmediation-http/v1/scp/triggerpoint2]

• The above URL has both the group name scp and the trigger point triggerpoint2. So the rules that are under the agenda-group scp-triggerpoint2 are applicable.
• From the below reference rules, the rule scp-rule-header-2 and scp-rule-body-1 will be applied.

Add the below rules to the mediation rules:

rule "default"
when
    m : NFHttpRequest(m.header("source") == "pcf")
then
    m.header(m.DEL, "custom-header-bad")
     
end
 
rule "scp-rule-header-1"
    salience 20
    agenda-group "scp"
when
    m : NFHttpRequest(m.header("custom-key") == "123")
then
    m.header(m.ADD, "custom-value", "pcf-nrf")
        m.header(m.UPDATE, "name", "nf","pcfnf")
end
 
rule "scp-rule-header-2"
    salience 20
    agenda-group "scp-triggerpoint2"
when
    m : NFHttpRequest(m.header("custom-key") == "123")
then
    m.header(m.ADD, "custom-value", "pcf-nrf")
        m.header(m.UPDATE, "name", "nf","pcfnf")
end
 
rule "scp-rule-body-1"
    salience 21
    agenda-group "scp-triggerpoint2"
when
    m : NFHttpRequest( (m.body("nfType") == "PCF") &&
                       (m.body("fqdn") matches "^(cisco).*") )
then
    m.body(m.ADD, "pcfInfo:supiRangeList[1]:end", "2000000000")
    m.body(m.ADD, "pcfInfo:supiRangeList[1]:start", "1000000000")
 
    m.body(m.UPDATE, "nfServices[1]:ipEndPoints[1]:ipv4Address", "10.75.213.100")
 
    m.body(m.DEL, "nfServices[1]:apiPrefix")
end
