Layer7 API Management

Hi All,

I am using API gateway 9.2.I need to add the JSON tag in all arrays and value should be unique in each array and send it in response.Below is my policy ,used Run Assertion for each time to get the JSON array response.But in response need to append 3 more tags in each array with unique value.Tried by using add XML element assertion but i am unable to add the XML element in all elements(value should be unique in each element).

Note : In the below sample response ,EWB ,date and valid are the added JSON tags.In that EWB value should be unique number.

Request you to please help on the above query.

Payload in setcontext variable and hardcoded parameters which is not the actual requirement

${formattedResponse}
{
docno:${docno.results[0]},
doctype:${doctype.results[0]},
docDate: ${docdate.results[0]},
"EWB":"1234567",
"date":"11/05/2018"
"valid":"11/06/2018"
}

Sample request Payload 

{
"invoices": [{
"supplyType": "O",
"subSupplyType": "1",
"subSupplyDesc": "",
"docType": "INV",
"docNo": "123-8",
"docDate": "15/12/2017"

},
{
"supplyType": "O",
"subSupplyType": "1",
"subSupplyDesc": "",
"docType": "INV",
"docNo": "123-8",
"docDate": "15/12/2017"

},
{
"supplyType": "O",
"subSupplyType": "1",
"subSupplyDesc": "",
"docType": "INV",
"docNo": "123-8",
"docDate": "15/12/2017"

}
]
}

Getting Response:

{
docno:123-8,
doctype:INV,
docDate: 15/12/2017,
"EWB":"1234567",
"date":"11/05/2018"
"valid":"11/06/2018"
}
{
docno:123-8,
doctype:INV,
docDate: 15/12/2017,
"EWB":"1234567",

"EWB":"1234567",
"date":"11/05/2018"
"valid":"11/06/2018"
}

Expected Response :

doctype:INV,
docDate: 15/12/2017,
"EWB":"any unique number",
"date":"11/05/2018"

"EWB":"any unique number",
"date":"11/05/2018"
"valid":"11/06/2018"
}

It seems you are already using the correct logic -- add new element(s) inside the loop. As EWB is unique, you just need to generate EWB inside the loop. for example, you can use Generate UUID assertion for EWB before set the formattedResponse.

Hi,

As suggested, used the Generate UUID assertion before formatted response variable,stored in ${unique} and set the variable in final response.It is generating unique variable but the same variable in all the arrays.But my requirement is the EWB variable should be different in all arrays.

Set Context variable:

${formattedResponse}
{
docno:${docno.results[0]},
doctype:${doctype.results[0]},
docDate: ${docdate.results[0]},
"EWB":"${unique}",
"date":"11/05/2018"
"valid":"11/06/2018"
}

Response :

{
docno:123-8,
doctype:INV,
docDate: 15/12/2017,
"EWB":"7594fb1a-7473-4253-a513-f2fc369cbcdb",
"date":"11/05/2018"
"valid":"11/06/2018"
}
{
docno:123-8,
doctype:INV,
docDate: 15/12/2017,
"EWB":"7594fb1a-7473-4253-a513-f2fc369cbcdb",
"date":"11/05/2018"
"valid":"11/06/2018"
}
{
docno:123-8,
doctype:INV,
docDate: 15/12/2017,
"EWB":"7594fb1a-7473-4253-a513-f2fc369cbcdb",
"date":"11/05/2018"
"valid":"11/06/2018"
}

Did you put Generate UUID assertion inside the loop? ie. under the Run Assertion for each item folder.

each time the Generate UUID assertion is executed, it generates a new UUID.

Hi ,

Thanks You!

Now it is resolved.Initially i used Generate UUID outside the loop so it giving same value in all arrays.After using it inside the loop,it worked.

Thanks & regards,
