JVM - api.route.get()
Register an API route and set a specific HTTP GET handler on that route.
import io.nitric.Nitric;class User {String name;int age;public User(String name, int age) {this.name = name;this.age = age;}}public class Application {public static void main(String[] args) {var api = Nitric.INSTANCE.api("public");api.route("/customers").get((ctx) -> {// construct response for the GET: /customers request...ctx.getResp().json(User("John Smith", 31));return ctx;});Nitric.INSTANCE.run();}}
Parameters
- Name
middleware
- Required
- Required
- Type
- HttpMiddleware or List<HttpMiddleware>
- Description
One or more middleware functions to use as the handler for HTTP requests. Handlers can be sync or async
Examples
Register a handler for GET requests
import io.nitric.Nitric;class User {String name;int age;public User(String name, int age) {this.name = name;this.age = age;}}public class Application {public static void main(String[] args) {var api = Nitric.INSTANCE.api("public");api.route("/customers").get((ctx) -> {// construct response for the GET: /customers request...ctx.getResp().json(User("John Smith", 31));return ctx;});Nitric.INSTANCE.run();}}
Chain functions as a single method handler
When multiple functions are provided they will be called as a chain. If one succeeds, it will move on to the next. This allows middleware to be composed into more complex handlers.
import io.nitric.Nitric;import io.nitric.faas.v0.HttpContext;import io.nitric.faas.v0.Handler;import java.util.List;public class Application {static HttpContext validateRequest(HttpContext ctx, Handler<HttpContext> next) {// validateRequestreturn next.invoke(ctx);}static HttpContext handleRequest(HttpContext ctx, Handler<HttpContext> next) {// handle requestreturn next.invoke(ctx);}public static void main(String[] args) {var api = Nitric.INSTANCE.api("public");api.route("/customer").get(List.of(Application::validateRequest, Application::handleRequest));Nitric.INSTANCE.run();}}
