When doing interface testing, some request parameters are repetitive or can be random, so we need to carry out interface parameterization.
The first step of interface parameterization is to locate and obtain parameters to be parameterized
The ApiPost provides a method for locating parameters, response.json(json to get the response value), in json
Get values from global variables or environment variables
A reference is made when the location gets the required parameter value
The method referenced by the APIPost is {{parameter name}}
