What is the best way to persist in asking until getting a specific response?

I am struggling to create code that iterates through a query until the desired result is achieved. Let's say I make this request:

{{API host}}/{{APP ID}}/{{REST API}}/hive/Management/set/keys?filterPattern=*&pageSize=5&cursor=0

The response from the server is:

{
    "keys": [],
    "cursor": "252"
}

Then, I take the value of cursor="252" and include it in the next query

{{API host}}/{{APP ID}}/{{REST API}}/hive/Management/set/keys?filterPattern=*&pageSize=5&cursor=252

This process should continue until the server responds with cursor="0"

I have been stuck on this problem for four days and I'm running out of ideas. Maybe implementing a while loop could help me solve it? Any assistance would be greatly appreciated.

Answer №1

My personal solution:

const data = pm.response.json();

if(data.pointer !== "0"){
    postman.setNextRequest("Your Request")
    pm.test('Pointer is not 0', () => {
        pm.expect(data.pointer, 'Error').to.not.eql("0")
    })
} else {
pm.test('Pointer is ' + data.pointer, () => {
    pm.expect(data.pointer).to.eql("0")
})
}

Hopefully this method can assist someone else
