本演示例程是继Java Tomcat SSL 服务端/客户端双向认证(一),密钥库可证书的生成脚本不再重复黏贴,仅仅是用程序来代替浏览器访问服务端。

例程中使用到了Apache HttpClient库,版本为4.1.3

全部依赖库:

commons-logging-1.1.1.jar

httpclient-4.1.3.jar

httpcore-4.1.4.jar

httpmime-4.1.3.jar(上传文件使用)


在(一)中的程序包中创建一个客户端类:HttpsClient

HttpsClient.java

        try {

            KeyStore trustStore  = KeyStore.getInstance(KEY_STORE_TYPE_JKS);
            InputStream ksIn = new FileInputStream(KEY_STORE_CLIENT_PATH);
            InputStream tsIn = new FileInputStream(new File(KEY_STORE_TRUST_PATH));
            try {
                keyStore.load(ksIn, KEY_STORE_PASSWORD.toCharArray());
                trustStore.load(tsIn, KEY_STORE_TRUST_PASSWORD.toCharArray());
            }
 finally {
                try { ksIn.close(); } catch (Exception ignore) {}
                try { tsIn.close(); } catch (Exception ignore) {}
            }

            SSLSocketFactory socketFactory = new SSLSocketFactory(keyStore, KEY_STORE_PASSWORD, trustStore);
            Scheme sch = new Scheme(SCHEME_HTTPS, HTTPS_PORT, socketFactory);
            httpClient.getConnectionManager().getSchemeRegistry().register(sch);
            HttpGet httpget = new HttpGet(HTTPS_URL);
            System.out.println("executing request" + httpget.getRequestLine());
            HttpResponse response = httpClient.execute(httpget);
            HttpEntity entity = response.getEntity();
            System.out.println("—————————————-");
            System.out.println(response.getStatusLine());
            if (entity != null{
                System.out.println("Response content length: " + entity.getContentLength());
                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(entity.getContent()));
                String text;
                while ((text = bufferedReader.readLine()) != null{
                    System.out.println(text);
                }

                bufferedReader.close();
            }

            EntityUtils.consume(entity);
        }
 finally {
            httpClient.getConnectionManager().shutdown();
        }

    }


}



启动Tomcat,运行HttpsClient,控制台返回:



OK,和使用浏览器访问得到的结果一模一样!
