啥也不说了,直接上代码,简单的示例。
服务端代码:
package dyan.server; import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.InetSocketAddress; import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
import com.sun.net.httpserver.spi.HttpServerProvider; public class DealMain
{ public static void main(String[] args) throws Exception
{
HttpServerProvider provider = HttpServerProvider.provider(); HttpServer server = provider.createHttpServer(new InetSocketAddress(6688), 10); server.createContext("/dyan", new DealMain().new DyanHttpHandler()); server.setExecutor(null);
server.start(); } class DyanHttpHandler implements HttpHandler
{ @Override
public void handle(HttpExchange arg0) throws IOException
{
System.out.println("accept an exchange from internet....."); String resp = "your request message i get it!"; BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(arg0.getRequestBody())); System.out.println(bufferedReader.readLine()); arg0.sendResponseHeaders(200, resp.getBytes().length); OutputStream out = arg0.getResponseBody();
out.write(resp.getBytes()); out.flush();
arg0.close();
} } }
请求代码:
public static void main(String[] args) throws Exception
{
URL url = null;
HttpURLConnection urlConnection = null; url = new URL("http://localhost:6688/dyan");
urlConnection = (HttpURLConnection)url.openConnection(); urlConnection.setRequestMethod("POST");
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setUseCaches(false); System.out.println("begin send parameters...."); urlConnection.getOutputStream().write("i am dyan".getBytes());
urlConnection.getOutputStream().flush();
urlConnection.getOutputStream().close(); InputStream in = urlConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(in)); System.out.println(bufferedReader.readLine()); bufferedReader.close(); urlConnection.disconnect();
}
先执行服务端代码,将服务端启动起来,来接收请求。
再执行请求代码,发起请求。
控制台打印信息如下:
1、请求端
begin send parameters....
your request message i get it!
2、服务端
accept an exchange from internet.....
i am dyan
