https p12证书请求解决问题过程

1.“No subject alternative names present” 异常解决

访问https,报javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names present

是对域名的不信任造成的

增加代码

static {  
     javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(  
     new javax.net.ssl.HostnameVerifier(){  
          public boolean verify(String hostname,javax.net.ssl.SSLSession sslSession) {  
                if (hostname.equals("localhost")) {  // for localhost testing
                     return true;  
                }else  if (hostname.equals(host)) {  //实际请求地址 host
                     return true;  
                }  
                return false;  
          }  
     });  
}  

2.数据请求代码

public static JSONObject httpsRequest(String requestUrl, String requestMethod, String params) {
        JSONObject jsonObject = null;
        StringBuffer buffer = new StringBuffer();
        try {
            KeyStore clientStore = KeyStore.getInstance("PKCS12");
            String keyStorePassword = "cert password";
            clientStore.load(WoJiaHttpsRequest.class.getResourceAsStream("/cert.p12"), keyStorePassword.toCharArray());
            KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
            kmf.init(clientStore,keyStorePassword.toCharArray());
            KeyManager[] kms = kmf.getKeyManagers();
            KeyStore trustStore = KeyStore.getInstance("JKS");
            trustStore.load(WoJiaHttpsRequest.class.getResourceAsStream("/jssecacerts"),"changeit".toCharArray());//信任域名证书jssecacerts
            TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
            tmf.init(trustStore);
            TrustManager[] tms = tmf.getTrustManagers();
            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(kms,tms, new SecureRandom());
            SSLSocketFactory ssf = sslContext.getSocketFactory();
        // 从上述SSLContext对象中得到SSLSocketFactory对象
            URL url = new URL(requestUrl);
            HttpsURLConnection httpUrlConn = (javax.net.ssl.HttpsURLConnection) url.openConnection();
            try{
                httpUrlConn.setSSLSocketFactory(ssf);
                httpUrlConn.setDoOutput(true);  
                httpUrlConn.setDoInput(true);  
                httpUrlConn.setRequestMethod(requestMethod);  
                httpUrlConn.setUseCaches(false);  
                httpUrlConn.setInstanceFollowRedirects(true);  
                httpUrlConn.setRequestProperty("Content-Type", "application/json");  
                httpUrlConn.setRequestProperty("Accept", "application/json");  
                httpUrlConn.setConnectTimeout(2000);
                httpUrlConn.setReadTimeout(3000);
                httpUrlConn.connect();  
                // 当有数据需要提交时
                if (null != params) {
                    OutputStream outputStream = new DataOutputStream(  
                            httpUrlConn.getOutputStream());
                    // 注意编码格式，防止中文乱码   
                    outputStream.write(params.getBytes("UTF-8"));
                    outputStream.flush();
                    outputStream.close();
                }
                // 将返回的输入流转换成字符串
                InputStream inputStream = httpUrlConn.getInputStream();
                InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
                BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
                String str = null;  
                while ((str = bufferedReader.readLine()) != null) {
                    buffer.append(str);
                }
                bufferedReader.close();
                inputStreamReader.close();
                // 释放资源   
                inputStream.close();
                inputStream = null;
                jsonObject = JSONObject.fromObject(buffer.toString());
            }catch(Exception e){
                    logger.error("http request error:{}", e);
            }finally{
                    if(httpUrlConn != null) httpUrlConn.disconnect();
            }
        } catch (ConnectException ce) {
            logger.error("server connection timed out.");
        } catch (Exception e) {
            logger.error("https request error:{}", e);
        }
        return jsonObject;
    }

3.jssecacerts的生成方法

编译：javac InstallCert.java    运行：java InstallCert 172.0.0.1 //域名地址，如果有端口要带端口
