Class HttpServer

java.lang.Object

ej.hoka.http.HttpServer

public class HttpServer
extends Object

HTTP Server.

Features + limitations:

• CLDC 1.1
• No fixed configuration files, logging, authorization, encryption.
• Supports parameter parsing of GET and POST methods
• Supports both dynamic content and file serving
• Never caches anything
• Doesn't limit bandwidth, request time or simultaneous connections
• Contains a built-in list of most common MIME types
• All header names are converted to lower case
• Keep-alive is not supported

Example:

 // get a new server which uses a ResourceRequestHandler
 HttpServer http = HttpServer.builder() //
                .port(8080) //
                .simultaneousConnections(3) //
                .workerCount(3) //
                .build();

 // register a route
 http.get("/", requestHandler);

 // start the server
 http.start();
 

To parse the request and write the response, a buffer size of 4096 by default is used. To change this value, set the property "hoka.buffer.size".
