To include dynamic or variable server URLs in a Swagger document, you can make use of server variables. Server variables allow you to define placeholders in the server URLs that can be replaced with actual values during runtime. Here's how you can do it:
Open your Swagger document (usually a YAML or JSON file) in an editor of your choice.
Locate the servers section in your Swagger document. If it doesn't exist, you can add it at the root level or within a specific API definition.
Inside the servers section, define a server object with the url property. This will serve as the base URL for your API.
Use curly braces {} to enclose the variable placeholders within the url. For example, {variable}.
Below the url property, define a variables object. This object will hold the mapping of the variable name to its values.
Inside the variables object, define each variable name as a property and specify its possible values using the enum property.
Save the Swagger document after making the necessary changes.
With this setup, you can provide different values for the server variables during runtime, allowing you to switch between different server URLs easily. The values for the server variables can be provided either through configuration files, environment variables, or programmatically, depending on the tool or framework you are using to serve your API.
Note that the implementation of server variables may vary depending on the specific Swagger tool or framework you are using. It's recommended to refer to the documentation or guides provided by the tool or framework you're working with for detailed instructions on how to define and use server variables in Swagger documents.
