Add parameter to JSON Body PUT Request while retaining parameters from GET request

I am trying to automate a task that adds a field to the request body in my PUT request.

Basically the first thing i do is a GET request to see what the request body looks like:
{
“jobName-0”: “/uscm-claims-training/job/boley-dynamic-secrets”,
“isTag-0”: “false”,
“triggers-0”: “add;prmerged;push;manual;delete;”,
“token-0”: “”,
“buildParameters-0”: “”,
“branchRegex-0”: “”,
“pathRegex-0”: “”
}

Now that i have that information I want to add a field (see below) while retaining all other values from the GET request so I want to add basically: this field:
"jenkinsServer-0": “USCM-CLAIMS-TRAINING”,

Is there a way to add a field to this? Each GET request has different values so I can’t just use the same body for each project.

Hi @MDrozdz17, welcome to the community! :wave:

You can make use of variables in Postman!

All you need to do is write the following in the test script:

// Get the response as JSON
let response = pm.response.json();

// Add the key to the object
response["jenkinsServer-0"] = “USCM-CLAIMS-TRAINING”;

// Set the whole response to a variable after stringifying it
pm.globals.set('jobResponse', JSON.stringify(response));

Now, in the request body of your PUT request, just write the following:

{{jobResponse}}

This should help you out.
Let me know if you have any doubts.

Thanks for the response sivcan that is very helpful.

On the line below if i wanted to replace “USCM-CLAIMS-TRAINING” with a variable i am using in my GET URL: called {{projectKey}} is there a way to do so? It does not seem to accept {{projectKey}}

response[“jenkinsServer-0”] = “USCM-CLAIMS-TRAINING”;

I was looking at the variables link you sent and it seems that you have to do something like this
let project = pm.iterationData.get(“projectKey”);

however when i do a console.log on “project” i am getting a null so I am doing something wrong.

@MDrozdz17 - pm.iterationData API is used with the collection runner, to access the data from the data file per iteration.

To access the globals / environments you can use pm.environment.get('keyName') / pm.globals.get('keyName') API.

@sivcan perfect thank you so much.

@sivcan,

One more question if you don’t mind. I’m not very proficient at Javascript, but i’ve got some data being returned with multiple jobNames as seen below:
Is there an easy way I can add the jenkinsServer property after each jobName? This one has 3, but some projectKeys have more than 20.

{
    "jobName-0": "DevOps/job/CFTs/job/secrets-test-mysql/",
    "isTag-0": "false",
    "triggers-0": "push;manual;",
    "token-0": "",
    "buildParameters-0": "VALIDATE_CFT=true\r\nCREATE_CHANGESET=true\r\nEXECUTE_CHANGESET=true\r\nBB_NEW_BRANCH=true\r\nGIT_TREEISH=$BRANCH\r\nBB_SHA=$COMMIT\r\nDEBUG=true\r\nprod_protection=yes;of course",
    "branchRegex-0": "^(bugfix|hotfix|feature|release)/.*",
    "pathRegex-0": "",
    "jobName-1": "DevOps/job/CFTs/job/secrets-test-mysql/",
    "isTag-1": "false",
    "triggers-1": "pullrequest;",
    "token-1": "",
    "buildParameters-1": "VALIDATE_CFT=true\r\nCREATE_CHANGESET=true\r\nEXECUTE_CHANGESET=false\r\nBB_PROPEN=true\r\nBB_PRDEST=$PRDESTINATION\r\nBB_PRID=$PRID\r\nGIT_TREEISH=$BRANCH\r\nBB_SHA=$COMMIT\r\nDEBUG=true\r\nprod_protection=yes;of course",
    "branchRegex-1": "",
    "pathRegex-1": "",
    "jobName-2": "DevOps/job/CFTs/job/secrets-test-mysql/",
    "isTag-2": "false",
    "triggers-2": "prmerged;",
    "token-2": "",
    "buildParameters-2": "VALIDATE_CFT=false\r\nCREATE_CHANGESET=false\r\nEXECUTE_CHANGESET=true\r\nBB_PROPEN=false\r\nBB_PRMERGE=true\r\nBB_PRDEST=$PRDESTINATION\r\nBB_PRID=$PRID\r\nGIT_TREEISH=$PRDESTINATION\r\nDEBUG=true\r\nprod_protection=yes;of course",
    "branchRegex-2": "",
    "pathRegex-2": ""
} 

Thanks,
Matt

I am assuming you want something like this:

{
    "jobName-0": "DevOps/job/CFTs/job/secrets-test-mysql/",
    "jenkinsServer-0": "USCM-CLAIMS-TRAINING",
    ...
    "jobName-1": "DevOps/job/CFTs/job/secrets-test-mysql/",
    "jenkinsServer-1": "USCM-CLAIMS-TRAINING",
    ...
    "jobName-2": "DevOps/job/CFTs/job/secrets-test-mysql/",
    "jenkinsServer-2": "USCM-CLAIMS-TRAINING",
} 

You can build an array and achieve that.
The script around that would be:

// We need the latest lodash, so importing it.
_ = require('lodash');

// Get the response as JSON
let response = pm.response.json();

// Based on the index of the array, we'll assign the value
// Right now, all three values are same but I am assuming
// you might want to change that too, you can either hard code that
// or build a logic around that.

// Number of jobNames
let jobNameCount = _.countBy(_.keys(response), (k) => k.includes('jobName')).true,

  // Fill an array with length of jobNameCount and all the values as 'USCM-CLAIMS-TRAINING' 
  uscms = _.fill(Array(jobNameCount), 'USCM-CLAIMS-TRAINING'),
  // This will be like this -> uscms = ['USCM-CLAIMS-TRAINING', 'USCM-CLAIMS-TRAINING', 'USCM-CLAIMS-TRAINING']

  // We'll populate this object, so declaring it here
  jenkinsServers = {};

_.forEach(uscms, (uscm, index) => {
  jenkinsServers[`jenkinsServer-${index}`] = uscm;
});

// Add all the new jenkins servers to the response object
response = _.assign(response, jenkinsServers);

// Set the whole response to a variable after stringifying it
pm.globals.set('jobResponse', JSON.stringify(response));

I haven’t tested the script, but I think it should work.
