1.“No subject alternative names present” 異常解決

訪問(wèn)https,報(bào)javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names present

是對(duì)域名的不信任造成的

增加代碼

1 static { 2 javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier( 3 new javax.net.ssl.HostnameVerifier(){ 4 public boolean verify(String hostname,javax.net.ssl.SSLSession sslSession) { 5 if (hostname.equals("localhost")) { // for localhost testing 6 return true; 7 }else if (hostname.equals(host)) { //實(shí)際請(qǐng)求地址 host 8 return true; 9 } 10 return false; 11 } 12 }); 13 }

2.數(shù)據(jù)請(qǐng)求代碼

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());//信任域名證書jssecacertsTrustManagerFactory 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();// 從上述SSLContext對(duì)象中得到SSLSocketFactory對(duì)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(); // 當(dāng)有數(shù)據(jù)需要提交時(shí)if (null != params) {OutputStream outputStream = new DataOutputStream( httpUrlConn.getOutputStream());// 注意編碼格式，防止中文亂碼 outputStream.write(params.getBytes("UTF-8"));outputStream.flush();outputStream.close();}// 將返回的輸入流轉(zhuǎn)換成字符串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();// 釋放資源 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

編譯：javac InstallCert.java ? ?運(yùn)行：java InstallCert 172.0.0.1 //域名地址，如果有端口要帶端口

?

4.InstallCert.java 代碼
