(Optional) Creating an Environment and Variable
An API can be called only after it is published in an environment. Publish it in different custom environments for development and testing. RELEASE is the system default environment for publishing APIs.
Environment variables are specific to environments. If environment variables are defined in backend information of an API, you need to add the variables to the corresponding environment. You can add variables in different environments to call different backend services using the same API.
Example: an API whose variable Path is defined in the backend request path. If variable Path is configured for environment 1 and is assigned value /Stage/test, use the backend request path /Stage/test to call this API in this environment. If variable Path is configured for environment 2 and is assigned value /Stage/AA, use the backend request path /Stage/AA to call this API in this environment.
Creating an Environment
- Log in to the ROMA Connect console. On the Instances page, click View Console of an instance.
- In the navigation pane on the left, choose API Connect > API Policies. On the Environments tab, click Create Environment.
- In the dialog box displayed, configure environment information and click OK.
When a user needs to call an open API, APIs in the RELEASE environment will be called by default. To access an API in another environment, add the X-Stage parameter to the header of the API request, where the parameter is the environment name. For example, to access an API in the Develop environment, add X-Stage: Develop to the header of the API request.
