Example 47 with Routing

use of io.helidon.webserver.Routing in project helidon by oracle.

the class UserFilterTest method filter.

@Test
public void filter() throws Exception {
    AtomicReference<User> userReference = new AtomicReference<>();
    Routing routing = Routing.builder().any(new UserFilter()).any((req, res) -> {
        userReference.set(req.context().get(User.class).orElse(null));

    response = TestClient.create(routing).path("/").header("Cookie", "Unauthenticated-User-Alias=Foo").get();
    assertEquals("Foo", userReference.get().getAlias());
}

Example 48 with Routing

use of io.helidon.webserver.Routing in project helidon by oracle.

the class Main method firstRouting.

// ---------------- EXAMPLES
/**
 * True heart of WebServer API is {@link Routing}. It provides fluent way how to assign custom {@link Handler} to the routing
 * rule. The rule consists from two main factors - <i>HTTP method</i> and <i>path pattern</i>.
 * <p>
 * The (route) {@link Handler} is a functional interface which process HTTP {@link io.helidon.webserver.ServerRequest request} and
 * writes to the {@link io.helidon.webserver.ServerResponse response}.
 */
public void firstRouting() {
    Routing routing = Routing.builder().post("/post-endpoint", (req, res) -> res.status(Http.Status.CREATED_201).send()).get("/get-endpoint", (req, res) -> res.status(Http.Status.NO_CONTENT_204).send("Hello World!")).build();
    startServer(routing);
}

Example 49 with Routing

use of io.helidon.webserver.Routing in project helidon by oracle.

the class Main method readContentEntity.

/**
 * Request payload (body/entity) is represented by {@link java.util.concurrent.Flow.Publisher Flow.Publisher}
 * of {@link DataChunk RequestChunks} to enable reactive processing of the content of any size.
 * But it is more convenient to process entity in some type specific form. WebServer supports few types which can be
 * used te read the whole entity:
 * <ul>
 *     <li>{@code byte[]}</li>
 *     <li>{@code String}</li>
 *     <li>{@code InputStream}</li>
 * </ul>
 * <p>
 * Similar approach is used for the response entity.
 */

    Routing routing = Routing.builder().post("/foo", (req, res) -> {
        req.content().as(String.class).whenComplete((data, thr) -> {

                System.out.println("/foo DATA: " + data);

Example 50 with Routing

use of io.helidon.webserver.Routing in project helidon by oracle.

the class Main method organiseCode.

/**
 * Larger applications with many routing rules can cause complicated readability (maintainability) if all rules are
 * defined in a single fluent code. It is possible to register {@link io.helidon.webserver.Service Service} and organise
 * the code into services and resources. {@code Service} is an interface which can register more routing rules (routes).
