How to extract value from json response in postman, whose key has '.' in it

Question

It is pretty straight forward to to get a value of a key from json response in postman say :

pm.test("AddCluster", function () {
    var jsonData = pm.response.json();
    pm.globals.set("taskIdCluster", jsonData.value);    
});

For JSON Response

{
    "value": "task-1405"
}

I am not able to extract json value in the below case where key has a '.' as part of its string.Can any one help me with this.

"result": {
        "cluster.moid": "domain-c433242"
    }

I tried the following below code:

pm.test("abc", function () {
    var jsonData = pm.response.json();
    var result = jsonData.result;
    var moid = result.'cluster.moid' ;
    pm.environment.set("clusterMoid", moid);
});

wonderful ! I suggest you edit and upgrade your answer so all the community can benefit from it, thanks ! — A.Joly

Could figure out to extract value for the above case, The below code works

pm.test("StatusForAddClusterApplyCheck", function () {
    var jsonData = pm.response.json();
    var result = jsonData.result;
    var jsonString = JSON.stringify(result).substring(17,31);
    pm.environment.set("clusterMoid", jsonString);
});

But only if the string length are constants.

Any other answer in case string length are dynamic?

In javascript (And also in postman), object properties can be accessed with '.' operator or with associative array indexing using []. The same goes for JSON objects.

ie. object.key is equivalent to object["key"].

this should do the trick for you:

pm.test("AddCluster", function () {
    var jsonData = pm.response.json();
    pm.globals.set("taskIdCluster", jsonData["cluster.moid"]);
});
