Getting started with postman -- environment variables and global variables

One 、 Send a request

Two 、 Set and reference environment variables

such as ： The production environment I built

Four 、 Interface Association

As long as it involves the interface that can only be operated after login , It is inevitable to quote token/session/ etc. . This reference is the value returned when logging in . such as , We're going to create labels , Transfer parameters need to be carried access_token, We already know that access_token Is to obtain access_token Return value of interface , We need to take out the return value , Then make a call in another interface

There are two ways , One is Json Extractor , We need to get access_token Interface

Tests Write the following code in ：

The last sentence is automatically added , Just click... On the right

Set a global variable Then modify the variable name and value

The next interface reference is also in { { Global variable name }}
