It is believed that many inexperienced people have no idea about the method of correlation testing for postman interface. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Application scenario

Suppose the next interface login requires the return value of the previous interface. For example, a request needs to log in to obtain the token, and the next request must carry the corresponding token before the request can be made.

Method: by setting global variable / environment variable method 1: setting global variable

1. First request the login API. If the request is successful, return the corresponding token

two。 Set global variables through js under tests after the corresponding first step request is successful

# get the return value of the API var jsonData = JSON.parse (responseBody); # obtain the corresponding value according to your own API result level and set it to the global variable pm.globals.set ('access_token',jsonData.access_token)

After the request is set successfully, you can view the value of the global variable here

3. Send a second interface request, which can refer to the set global variable by {{access_token}}

Method 2: environmental variables

1. Add environment variabl

two。 Select the name of the environment variable and send a request to get token

Var jsonData = JSON.parse (responseBody); / / Environment variable assignment. Hh is my name. You can name it pm.environment.set ("hh", jsonData.access_token).

3. After sending the message successfully, you can see that the token value has been set successfully.

3. Select the same environment variable name, fill in the parameter name {{hh}} you just set, and send the request.
