Interface Association of postman

In the project , Multiple interfaces are related to each other before .

Such as ： After registration, you can log in , It is impossible for a business to add, delete, modify, and query one interface at a time , If a parameter can be added, modified, and then deleted D It's all related , You need to get the first interface , Then when the following interface is used, you can call

Here is an example ： The request needs to log in to get token, The next request needs to carry the corresponding token To make a request

One 、json The extractor implements Interface Association

1、 Request login interface , The corresponding... Is returned after success token

Cold start ： When starting the app , There is no process for this application in the background , At this time, the system will re create a new process to assign to the application , The starting mode is cold starting .

Hot start ： When starting the app , The application process already exists in the background （ example ： Press back key 、home key , The app will exit , However, the process of the application will still remain in the background , You can enter the task list to view ）, So in the case of existing processes , This startup will start the application from the existing process , This startup mode is called hot startup .

2、 After the first step is successful Tests Pass through js To set global variables

//json The extractor gets the return value

var jsonData = pm.response.json();
// You can print and view the returned token value
console.log(jsonData.detail.token)
// Obtain the corresponding value according to the interface result level , Set to global variable
pm.globals.set("token", jsonData.detail.token);

After sending, you can view the details in the control view ：

See global variable value ：

3、 Send the second interface request , It can be done by { {token}} Reference the set global variable

 

4、 Send a request

Two 、 The regular expression extractor implements interface correlation

It is still after the first step of the request Tests Pass through js To set up

//match matching , obtain token value
var result = responseBody.match(new RegExp('"token":"(.*?)"'))
// Take the subscript 1 Value
console.log(result[1]);
// Set to global variable
pm.globals.set("token",result[1]);

Other operations are the same as above .
