Resolve Parameter Dependencies, Data Passing Between Interfaces

Usage Scenario​

B interface request parameters depend on the data returned by A interface. We hope that when B interface sends a request, it can get the data returned by A interface as request parameters.

Implementation Idea​

Assign the data returned by interface A to a global variable or environment variable through a post-execution script.

Specific Example​

We need the token parameter returned by the login interface for a news list. A common scenario is accessing an interface that requires login to view.

1. Prepare the interfaces​

For demonstration purposes, we first prepare two interfaces:

get_token interface:

Request URL: {{url}}/api/demo/login

It will return a token parameter. As shown in the figure:

News list interface:

Request URL: {{url}}/demo/news_list?mobile=****&theme_news=International News&page=1&pageSize=20

It requires the token parameter returned by the login interface as its request parameter.

2. Bind the response result to the variable​

At this point, click the [Post-execution Operation - Custom Script] of the login interface, and assign the login response result token to the environment variable token through a variable assignment.

We enter the news list interface and click send, and you will see that the token is the token we just obtained.

Appendix: Response Data Variables​

response.raw: Original response data​

Call example:​
response.raw.status // Response status code (200, 301, 404, etc.)
response.raw.responseTime // Response time (milliseconds)
response.raw.type // Response type (json, etc.)
response.raw.responseText // Response text

response.json: JSON format response data​

Call example as shown above:

response.json.data.token // or response.json.data["token"]

response.headers: Response headers​

Call example:

response.headers.server // or response.headers["server"]

response.cookies: Response cookies​

Call example:

response.cookies.PHPSESSION // or response.cookies["PHPSESSION"]
