Postman: Use the request name within the declaration of an environment variable

I would like to use Postman to set an Environment variable in a dynamic way and use the dataObject..attribute2's values based on the request name. This script is used within the Pre-req section.

Situation: I have a json data object:

var dataObject = {

    "request01": {
        "attribute1": 123456789,
        "attribute2": "asdfghjkl"
    },
    "request02": {
        "attribute1": 987654321,
        "attribute2": "lkjhgfdsa"
    }
}

And I have these 2 requests in the same folder with the names:

  • request01
  • request02

Now, I want to define the value of this allocation, so I assign the attribute2 value to the variable dynamicAttribute2. If I do this in a static way it is like this:

postman.setEnvironmentVariable("dynamicAttribute2", dataObject.request02.attribute2);

Now this question how to do it properly in a dynamic way, depending on the request name, each. I tried to do this:

postman.setEnvironmentVariable("dynamicAttribute2", dataObject.{request.info.name}.attribute2);

The issue is that Postman cannot resolve the object reference to the attribute.

Question

What's the correct way to use this?

You can dynamically access an object's key (to retrieve the property or set it) using square brackets, similar to arrays. This should work:

postman.setEnvironmentVariable(
  "dynamicAttribute2",
  dataObject[request.info.name].attribute2
);
