HttpServer和HttpsServer简单实现

博客分类：

java编程

javaSE本身自己就实现了web功能，分别有两种实现一种是HTTP、HTTPS，实现类分别为HttpServer和HttpsServer但是都要自己实现HttpHandler，而且HTTPS的实现要麻烦一些需要创建证书。创建证书的工具java的bin目录下有名字叫keytool创建方法入下：

Java代码

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
import com.sun.net.httpserver.HttpsConfigurator;
import com.sun.net.httpserver.HttpsServer;
public class HTTpServer {
public static void main(String[] args) throws IOException, KeyStoreException, NoSuchAlgorithmException, CertificateException, UnrecoverableKeyException, KeyManagementException {
//http实现
HttpServer http = HttpServer.create(new InetSocketAddress(InetAddress.getByName("127.0.0.1"), 8989),0);
http.createContext("/web", new HTTpServer().new MyHandler());
http.setExecutor(null);
http.start();
//https实现
HttpsServer https = HttpsServer.create(new InetSocketAddress(InetAddress.getByName("127.0.0.1"), 8787), 0);
https.createContext("/web", new HTTpServer().new MyHandler());
https.setExecutor(null);
KeyStore ks = KeyStore.getInstance("JKS"); //建立证书库
ks.load(new FileInputStream("F:/serverkeys"), "luoxun".toCharArray()); //载入证书
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509"); //建立一个密钥管理工厂
kmf.init(ks, "luoxun".toCharArray()); //初始工厂
SSLContext sslContext = SSLContext.getInstance("SSLv3"); //建立证书实体
sslContext.init(kmf.getKeyManagers(), null, null); //初始化证书
HttpsConfigurator httpsConfigurator = new HttpsConfigurator(sslContext);
https.setHttpsConfigurator(httpsConfigurator);
https.start();
}
class MyHandler implements HttpHandler{
public void handle(HttpExchange exchange) throws IOException {
String protocol = exchange.getProtocol();
String method = exchange.getRequestMethod();
String url = exchange.getRequestURI().toString();
String query = exchange.getRequestURI().getQuery();
InputStream request =exchange.getRequestBody();
OutputStream response = exchange.getResponseBody();
InetSocketAddress address = exchange.getRemoteAddress();
String host = address.getHostName();
String port = String.valueOf(address.getPort());
StringBuilder sb = new StringBuilder();
sb.append("<meta http-equiv=‘charset‘ content=‘text/html;charset=gb2312‘>");
sb.append("协议：%s");
sb.append("提交方式：%s");
sb.append("URL：%s");
sb.append("参数列表：%s");
sb.append("主机名：：%s");
sb.append("端口号：%s");
String content = String.format(sb.toString(), protocol,method,url,query,host,port);
byte[] contentBin = content.getBytes();
exchange.sendResponseHeaders(200, contentBin.length);
response.write(contentBin);
response.flush();
response.close();
}
}
}
