Need to access KVM values in Javascript policy

[Vigneshwar2411]

I’m working on a Apigee x proxy setup. I need to construct a request body which will be used in a Service Call-out. 

I need to append a value from KVM to the request body that is being constructed on the JS policy. 

Can someone suggest me how to access KVM values in Javascript policy?

There's no direct access to KVM entries via JavaScript, so you'll need to use a KVM policy to access the entries and assign to a variable.

<KeyValueMapOperations name="KV-log-config" mapIdentifier="my-kvm-name">
    <Get assignTo="my_kvm_variable" index="1">
        <Key>
            <Parameter>my_kvm_variable</Parameter>
        </Key>
    </Get>
 <Scope>environment</Scope>
</KeyValueMapOperations>

Then in your JavaScript add that variable to your request body.

var myKVMVariable = context.getVariable('my_kvm_variable');
var reqObject = {
    "myKVMVariable" : myKVMVariable,
...
};
context.setVariable("message.content", JSON.stringify(reqObject));            

Hope that's clear.
