使用其HTTP API打開與APNS的連接時發生無效的Http響應

Question

我正在編寫一個模塊，用於使用其新的HTTP提供程序API將推送通知發送到使用APN的IOS設備。但是我在閱讀過程中遇到了一些問題從response.Its拋出以下一個無效的HTTP響應和error.The輸出是一段代碼，我已經寫了：

static SSLSocketFactory getSSLSocketFactory() { 
     try { 
      String keystoreFilename = "D:/Oracle/IDCS/MFA/APNS/OMA_prereqs/iOS_prod.p12"; 
      char[] storepass = "welcome1".toCharArray(); 
      FileInputStream fis = new FileInputStream(
        new File(keystoreFilename)); 

      final KeyStore ks = KeyStore.getInstance("PKCS12"); 
      ks.load(fis, storepass); 

      KeyManagerFactory keyManagerFactory = KeyManagerFactory 
        .getInstance("SunX509"); 
      keyManagerFactory.init(ks, storepass); 

      TrustManagerFactory trustManagerFactory = TrustManagerFactory 
        .getInstance("SunX509"); 
      trustManagerFactory.init((KeyStore) null); 
      // trustManagerFactory.init(ks); 

      // create ssl context 
      SSLContext sslContext = SSLContext.getInstance("TLSv1.2"); 


      // setup the HTTPS context and parameters 
      sslContext.init(keyManagerFactory.getKeyManagers(), 
        trustManagerFactory.getTrustManagers(), null); 

      if (keyManagerFactory != null || trustManagerFactory != null) { 
       return SSLTunnelSocketFactory.wrap(proxy, 
         sslContext.getSocketFactory()); 
      } 
     } catch (Exception e) { 
      System.out.println("Unable to create ssl socket factory"); 
      e.printStackTrace(); 
     } 
     return HttpsURLConnection.getDefaultSSLSocketFactory(); 
    } 

    private static void sendSamplePushNotification() { 
       System.setProperty("javax.net.debug", "all"); 
       URL url = null; 
       try { 
        HostnameVerifier hv = new HostnameVerifier() { 
         public boolean verify(String urlHostName, SSLSession session) { 
          return true; 
         } 
        }; 
        JSONObject payload = new JSONObject(); 
        JSONObject msg = new JSONObject(); 
        try { 
         msg.put("alert", "Hello APNS"); 
         payload.put("aps", msg); 
        } catch (JSONException e) { 
         e.printStackTrace(); 
        } 
        url = new URL(
          "https://api.development.push.apple.com:443/3/device/00fc13adff785122b4ad28809a3420982341241421348097878e577c991de8f0"); 
        HttpsURLConnection conn = (HttpsURLConnection) url 
          .openConnection(proxy); 
        conn.setRequestMethod("POST"); 
        conn.setDoOutput(true); 
        conn.setHostnameVerifier(hv); 
        conn.setSSLSocketFactory(getSSLSocketFactory()); 
        /*conn.setRequestProperty("content-length", new String(payload 
          .toString().getBytes()));*/ 
        conn.setConnectTimeout(3000); 
        conn.connect(); 
        OutputStream os = conn.getOutputStream(); 
        OutputStreamWriter writer = new OutputStreamWriter(os); 
        BufferedWriter bw = new BufferedWriter(writer); 
        bw.write(payload.toString()); 
        bw.flush(); 
        //System.out.println("Response code : " + conn.getResponseCode()); 
        System.out.println(conn.getResponseMessage()); 
        InputStream is = conn.getInputStream(); 
        ................ 
      } 

我得到上執行此下列情況除外：

燦有人請幫助我？ SSL握手似乎很好。它在線'conn.getInputStream（）'失敗'

Answer 1

首先，我在我的角色中添加了評論，作爲新問題的評論者。堆棧跟蹤增加了人們想出來的機會。

其次，它會幫助你找到導致崩潰的行，因爲堆棧跟蹤沒有列出你的代碼（可能還有1個？）。請注意，與空指針不同，無效的HTTP響應不一定是您的代碼的問題。這導致我...

第三，和我寫這個作爲答案的原因，用Java它可能是餅乾。嘗試：

CookieManager cookieManager = new CookieManager(); 
CookieHandler.setDefault(cookieManager); 

第四，如果一切都失敗了，你需要弄清楚郵遞員，無論是未來走出的Java代碼之間的差異。 wireshark或類似的工具可能會伎倆。

更新： This崗位上的超級用戶似乎表明Java 7的默認禁用TLS1.2。

我看到你正在發送TLS1.2。如果你使用Java 7，看起來有bug affecting updates 25 and above。

從「APNs Provider API」文檔：「此API基於HTTP/2網絡協議」。 Java目前不支持HTTP/2。預計Java 9會支持HTTP/2。 您需要使用第三方HTTP客戶端，這裏是sugestions：Does Apache or some other CLIENT JAVA implementation support HTTP/2?
