environment variable
Environment variables As the name suggests, we can set variables for both the test environment and the production environment .
For example, we set the value of a variable in the test environment to be A, but the value of the production environment is B. At this time, the environment variable can be used . Of course, we can also change it manually without using the environment variable, but imagine that if this variable is used 10 times, and the value remains the same each time, if we manually change it, do we need to change it 10 times? So using environment variables can simplify things.
Example:
Interface address: https://www.v2ex.com/api/nodes/show.json?name=python
For example , the name value used in our test environment is python , and the name value used in the production environment is php , so how should we edit it?
Set test environment and production environment variables
Step 1: Click on the little eye and click edit in the Environment column
Step 2: Set the values for the test environment and the production environment
Step 3: Use the variable values of the test environment and production environment to test. Note here that 2 curly braces are required to refer to variables.
Step 4: View the running results
global variable
The setting method is similar to the environment variable
Step 1: Click on the little eye and click edit in the Globals column
Step 2: Use global variables and see the results
