This time I will show you how Postman transfers token parameters. What are the precautions for Postman when transferring token parameters? The following is a practical case, let's take a look.

Problem description:

There is a login interface to obtain the token, and you must bring the token when accessing other interfaces again

Solution:

1. Set the Postman environment variable (Environment) after accessing the login interface, for example

Set the environment variable Name: token, The value is the token value in responseBody after successful access to the login interface. Please see the detailed description below for how to set it.

2. When accessing other interfaces, the token value can be directly read from the variable. The syntax for obtaining variables in Postman is: {{

Variable name}}

Specific steps:

1. Introduction to the login interface

As shown in the figure, the JSON format of the login interface return value is roughly:

{
  "status": 0,
  "message": "成功",
  "data": {
    "username": "cams_admin_dev",
    "token": "eyJhbGciOiJIUzUxMiJ9.eyJleHAiOjE1MTYzNDIxMjAsInN1YiI6ImNhbXNfYWRtaW5fZGV2IiwiY3JlYXRlZCI6MTUxNjI1NTcyMDU0NywiZnVsbCI6ImNhbXNfYWRtaW5fZGV2IiwidWF1dGgiOiIvKio7QUxMIiwiYXV0aCI6InNldHRpbmdzLGNhbXNfYWRtaW4saW5kdXN0cnksYm9uZCxjYW1zSG9tZSxjb21wYW55LGFyZWEsZGV0YWlscyxjYW1zT3BlcmF0aW9uIn0.pI09X8KNoIK0fb6xC1xbrSZyg-EnUnlZ_9shmOQCRDtdIIEA5iyq3HmzgSx0ReaChEAZxkrrSRTtSXE8ZlbCTw"
  }
}

Copy after login

The return value contains the token value , how can this value be automatically set as a Postman environment variable after accessing the login interface?

2. After accessing the login interface, it is automatically set to the Postman environment variable

Write the following code in the Tests of the Postman software to set the environment variable

pm.test("Status code is 200", function () { 
  pm.response.to.have.status(200); 
}); 
 
// 把responseBody转为json字符串 
var data = JSON.parse(responseBody); 
// 设置环境变量token，供后面的接口引用 
pm.environment.set("token", data.data.token);

Copy after login

As shown in the figure below:

After clicking the Send button to send the request, you can dynamically set the environment variable named token with the value of the token value.

After the setting is successful, click the eye icon and view the variables as shown in the figure:

3. Access other interfaces, environment variable token

As shown in the red mark

1. Another interface

2. Select the token type in TYPE. What I use here is Bearer Token

3. Set the token value in the red marked part on the right. The format is: {{token}} to get the previous login interface. If the token is dynamically set during access, then this interface can be used.

Click Send and the access will be successful.

I believe you have mastered the method after reading the case in this article. For more exciting information, please pay attention to other related articles on the php Chinese website!
