Simple HTTP API example

Popok use undertow as HTTP server, so creating a router is as simple as creating an undertow HttpHandler.

// Router
HttpHandler router = Handlers.path()
  .addPrefixPath("/api/v1", Handlers.routing()
    .get("/hello", (exchange) -> {
      exchange.setStatusCode(StatusCodes.OK);
      exchange.getResponseSender().send("Hello World!");
    })
  );
// Create and start the server
Server.builder(router)
  .build()
  .start();

Bootstrapping a Server

Server.java it's just an Undertow wrapper class to add some functionality such as: HTTPs/HTTP2 support and HTTP to HTTPs redirection. To instantiate a Server you have to provide an undertow HttpHandler as router and use the builder API that provides you the following methods:

/**
* Sets a different name for the properties configuration file.
* If you don't use this method popok will look inside 'resources'
* folder, looking for 'app.properties' default file.
*/
propertiesFilename(String name)

/**
* Enables HTTPs support. You have to specify the keystore path,
* popok will look inside 'resources' folder, looking for the 'keyStorePath'.
*/
enableHttps(String keyStorePath)

/**
* Enables HTTP to HTTPs redirection. You have to specify which
* HTTP `3XX` code you want to use.
*/
redirectToHttps(int statusCode)

/**
* Enables HTTP2 support.
*/
enableHttp2()

The mandatory fields, that popok needs for the properties configuration file, are:

• server.http.port to specify the HTTP port (an integer).
• server.address to specify the address of the server (an IP or localhost).

Additionally, you can specify optional configuration fields in order to activate HTTPs:

• server.https.port to specify the HTTPs port (an integer).
• security.key.store.password to specify the keystore password.

An example of app.properties file could be:

server.http.port=8080
server.address=localhost
server.https.port=8443
security.key.store.password=password
