java写http服务器只接受post方式请求和get方式

请求的示例代码：

import java.io.IOException;
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;

public class MyHttpServer {

    public static void main(String[] args) throws Exception {
        HttpServer server = HttpServer.create(new InetSocketAddress(8000), 0);
        server.createContext("/", new MyHandler());
        server.setExecutor(null);
        server.start();
        System.out.println("Server started on port 8000");
    }

    static class MyHandler implements HttpHandler {
        @Override
        public void handle(HttpExchange exchange) throws IOException {
            String requestMethod = exchange.getRequestMethod();
            if (requestMethod.equalsIgnoreCase("GET")) {
                handleGetRequest(exchange);
            } else if (requestMethod.equalsIgnoreCase("POST")) {
                handlePostRequest(exchange);
            }
        }

        private void handleGetRequest(HttpExchange exchange) throws IOException {
            String response = "This is a GET request";
            exchange.sendResponseHeaders(200, response.length());
            OutputStream os = exchange.getResponseBody();
            os.write(response.getBytes());
            os.close();
        }

        private void handlePostRequest(HttpExchange exchange) throws IOException {
            String response = "This is a POST request";
            exchange.sendResponseHeaders(200, response.length());
            OutputStream os = exchange.getResponseBody();
            os.write(response.getBytes());
            os.close();
        }
    }
}

该示例代码创建了一个监听在8000端口的HTTP服务器，并通过createContext方法指定了默认的处理程序为MyHandler。MyHandler实现了HttpHandler接口，可以处理来自客户端的HTTP请求。

在handle方法中，根据请求方法的不同，调用了handleGetRequest或handlePostRequest方法处理GET或POST请求。这两个方法分别向客户端发送了不同的响应。在响应中，我们使用sendResponseHeaders方法指定了HTTP状态码和响应体的长度，并使用getResponseBody方法获取输出流，向客户端发送响应体。

通过这种方式，我们可以创建一个简单的HTTP服务器，只接受GET和POST请求
