grouping Collection

At the beginning of a project , For the convenience of organization and management , Multiple projects belonging to the same project API, Put it in a group

So we have to build a new one first Collection: New -> Collection

After a period of use , Built the effect of multiple groups ：

The effect of expanding a single group ：

Historical record History

Postman Support history Historical record , Show recently used API： 

Use environment variables to realize multi server version

Existing problems

In the test API period , There are often multiple environments , Corresponding IP Address （ Or domain names ）

such as ：

• Prod: http://116.62.25.57/ucows

• It is used to release the development to the production environment

• Dev: http://123.206.191.125/ucows

• For online during development Development Test environment for

• LocalTest: http://192.168.0.140:80/ucows

• It is used for the local environment in the local LAN to cooperate with background developers during development , For joint debugging API Interface

While testing API period , It often needs to be modified manually API The address of ：

Low efficiency , And after the address is changed, the address cannot be retained .

in addition , And according to different IP Address （ Or domain name ） It's not easy to identify which environment it is .

Postman Support with Environment Environment variable to implement multi server version

It turned out Postman in , Yes Environment and Global Variable, To solve this problem , Realize the management of different environments ：

Obviously , Can be used to achieve without manual modification url Server address in , So as to dynamically realize , Support different server environments :

• Production Production environment

• Development development environment

• Local Local LAN environment

How to use Enviroment Implement multi server version

perhaps ：

 

Environments are a group of variables & values, that allow you to quickly switch the context for your requests and collections.

Learn more about environments

You can declare a variable in an environment and give it a starting value, then use it in a request by putting the variable name within curly-braces. Create an environment to get started.

Input Key and value：

Click on Add after ：

[info] Where environment variables can be used

• URL

• URL params

• Header values

• form-data/url-encoded values

• Raw body content

• Helper fields

• Write test In the test script

• adopt postman The interface of , Gets or sets the value of the environment variable .

Here, put the previous in url Medium IP Address （ Or domain name ） Change to environment variable ：

Move the mouse over the environment variable , Can dynamically display specific values ：

Then add another development environment ：

You can add 2 Environment variables , Indicates two server addresses , Two versions ：

Then you can switch between different server environments ：

You can see , Same variable server_address, After switching, it corresponds to IP The address becomes the of the desired development environment IP 了 ：

Postman export API The effect of multiple environment variables in the document

Take a look by the way , Export to API After the documents , With this Environment Interface of variables , What does the document look like ：

The discovery was before the release , You need to select the corresponding environment ：

Published documents , You can see the of the selected environment and the corresponding server IP Of ：

Of course, after publishing the document , You can also switch the environment in real time ：

The benefits of environmental variables

When replacing the server , Directly modify the of variables IP Address ：

It can be updated in real time , When the mouse moves over the variable, you can see the effect ：
