JVM - api.route.post()

Register an API route and set a specific HTTP POST handler on that route.

import io.nitric.Nitric;

public class Application {
  public static void main(String[] args) {
	var api = Nitric.INSTANCE.api("public");

	api.route("/customers").post((ctx) -> {
	  // handle POST request
	  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 POST requests

import io.nitric.Nitric;

public class Application {
  public static void main(String[] args) {
	var api = Nitric.INSTANCE.api("public");

	api.route("/customers").post((ctx) -> {
	  // handle POST request
	  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) {
	// validateRequest
	return next.invoke(ctx);
  }

  static HttpContext handleRequest(HttpContext ctx, Handler<HttpContext> next) {
	// handle request
	return next.invoke(ctx);
  }

  public static void main(String[] args) {
	var api = Nitric.INSTANCE.api("public");

	api.route("/customer").post(List.of(Application::validateRequest, Application::handleRequest));

	Nitric.INSTANCE.run();
  }
}

Access the request body

The POST request body is accessible from the ctx.req object.

import io.nitric.Nitric;

public class Application {
  public static void main(String[] args) {
	var api = Nitric.INSTANCE.api("public");

	api.route("/customer").post((ctx) -> {
	  var customerData = ctx.getReq().getData();
	  // parse, validate, and store the request payload...
	});

	Nitric.INSTANCE.run();
  }
}
