在邮递员中使用集合变量

问题描述

All the examples on learning.getpostman.com site show how to save variables at the global or environment level, in order to get a value from one request to another.

For example:

pm.environment.set(variableName:String, variableValue:String)
pm.environment.get(variableName:String)

pm.globals.set(variableName:String, variableValue:String)
pm.globals.get(variableName:String)

respectively.

Is it possible to use Collections instead?

Reading the documentation about the pm. API doesn't give me much hope.

I am looking for something like this:

pm.collection.set(variableName:String, variableValue:String)
pm.collection.get(variableName:String)

My goal is to be able to run two collections without cross-contamination.

解决方案

The latest Postman version available to update (7.9.0), ships with a new pm.collectionVariables function, this gives users more control over the way that they interact with Variables, at the Collection level.

Previously, you could only manually add these variables and then access them in the sandbox environment using the pm.variables.get("var_name") function.

The new pm.collectionVariables API method comes with the follows functions:

 .get("var_name")
 .set("var_name", "var_value")
 .has("var_name")
 .unset("var_name")
 .clear()
 .toObject()

An example of the syntax would be this:

pm.collectionVariables.set("collectionVariable", "My Awesome New Collection Level Variable");

This is a basic example of setting a Collection level Variable from the Tests tab:
