Resource path parameters
Path segments can be treated as parameters in Ballerina.
import ballerina/http;
service /demo on new http:Listener(8080) {
// Here is how you can make path segments as parameters.
resource function get greeting/hello/[string name]() returns string {
return "Hello, " + name;
}
}
Run the service using the bal run command.
$ bal run resource_path_parameters.balRun this cURL command to invoke the resource.
$ curl "localhost:8080/demo/greeting/hello/Ballerina"Hello, BallerinaPreviousHierarchical resources
