java调用bitcoin的JSON-PRC

1：通过SSLSocketFactory和HttpsURLConnection调用

参见azazar的bitcoin.jsonrpcclient

环境：JDK1.7 

依赖：openssl 生成的server.cert和server.pem

导入server.cert到java keystore

1A:JKS

keytool -import -alias aliasName -v -file C:\..\server.cert -keystore  C:\..\jks.keystore -storepass pwd     

keytool -list -v -keystore C:\..\jks.keystore -storepass pwd

1B: HostnameVerifier：不检查证书的CN和请求的hostname是否一致

      public   static  HostnameVerifier createHostnameVerifier() {

         return   new  HostnameVerifier() {

                    @Override

                    public   boolean  verify(String paramString, SSLSession paramSSLSession) {

                          return   true ;

                  }

            };

    }

1C: SSLSocketFactory  

      public   static  SSLSocketFactory createSslSocketFactory(String JKSPath,String JKSPwd)  throws  Exception {

      KeyStore keyStore = KeyStore. getInstance(  "JKS" );

        // TODO  need to be changed into real path in linux

            keyStore.load(  new  FileInputStream(JKSPath), JKSPwd.toCharArray());

      TrustManagerFactory tmf = TrustManagerFactory.getInstance(  "SunX509" );

            tmf.init(keyStore);

            SSLContext ctx = SSLContext. getInstance(  "TLS" );

            ctx.init(  null , tmf.getTrustManagers(),  null );

            SSLSocketFactory sslSocketFactory2 = ctx.getSocketFactory();

         return  sslSocketFactory2;

    }

1D:使用

              if  (conn  instanceof  HttpsURLConnection) {

                 if  (  hostnameVerifier  !=  null )

                    ((HttpsURLConnection)conn).setHostnameVerifier( hostnameVerifier  );

                 if  (  sslSocketFactory  !=  null ){

                        ((HttpsURLConnection)conn).setSSLSocketFactory(  sslSocketFactory );

                }

                  

            }

1E： 入参的 包装和解析bitcoin的响应JSON请查看源码 com.azazar.bitcoin.jsonrpcclient. BitcoinJSONRPCClient.query

2：通过HttpClient调用,simple JSON解析

环境：JDK1.7 httpclient-4.3.4.jar httpcore-4.3.2.jar

依赖：openssl 生成的server.cert和server.pem

2B:

        public   static  LayeredConnectionSocketFactory createSSLFactory(String JKSPath, String JKSPwd)

                    throws  Exception {

            KeyStore trustStore = KeyStore. getInstance(  "JKS" );

            FileInputStream instream =  new  FileInputStream(  new  File(JKSPath));

              try  {

                  trustStore.load(instream, JKSPwd.toCharArray());

            }  finally  {

                  instream.close();

            }

              // Trust own CA and all self-signed certs

            SSLContext sslcontext = SSLContexts. custom()

                        .loadTrustMaterial(trustStore,  new  TrustSelfSignedStrategy()).build();

              // Allow TLSv1 protocol only

            SSLConnectionSocketFactory sslsf =  new  SSLConnectionSocketFactory(sslcontext,

                          new  String[] {  "TLSv1"  },  null ,

                        SSLConnectionSocketFactory.  ALLOW_ALL_HOSTNAME_VERIFIER  );

              return  sslsf;

      }

2C: org.apache.http.impl.client.HttpClients

            CloseableHttpClient httpclient;

              try  {

                  httpclient = HttpClients.custom().setSSLSocketFactory( createSSLFactory( jksPath  ,  jksPwd )).build();

            }  catch  (Exception e1) {

                  httpclient = HttpClientBuilder. create().build();

                  e1.printStackTrace();

            }

            HttpHost targetHost =  new  HttpHost(  host ,  port ,  "https"  );

            JSONObject json =  new  JSONObject();

            json.put(  "id" , id);

            json.put(  "method" , method);

              if  (!CollectionUtils. isEmpty(params)) {

                  JSONArray array =  new  JSONArray();

                  array.addAll(params);

                  json.put(  "params" , params);

            }

            JSONObject responseJsonObj =  null ;

              try  {

                  CredentialsProvider credsProvider =  new  BasicCredentialsProvider();

                  credsProvider.setCredentials(  new  AuthScope(  host ,  port ),

                                new  UsernamePasswordCredentials(  rpcuser ,  rpcpwd ));

                    // Create AuthCache instance

                  AuthCache authCache =  new  BasicAuthCache();

                    // Generate BASIC scheme object and add it to the local auth cache

                  BasicScheme basicAuth =  new  BasicScheme();

                  authCache.put(targetHost, basicAuth);

                    // Add AuthCache to the execution context

                  HttpClientContext context = HttpClientContext.create();

                  context.setCredentialsProvider(credsProvider);

                  context.setAuthCache(authCache);

                  HttpPost httppost =  new  HttpPost(  url );

                  StringEntity myEntity =  new  StringEntity(json.toJSONString());

                  httppost.setEntity(myEntity);

                  CloseableHttpResponse response = httpclient.execute(targetHost, httppost, context);

                  HttpEntity entity = response.getEntity();
