我可以使用paho {mqttv3:1.1.0}服务在没有TLS/SSL证书的情况下执行与Broker的MQTT连接.但是,当我尝试在Android中固定SSL证书时,它无法正常工作.请帮我解决这个问题.附加代码以获得更多洞察力.

第1步:证书转换

将certificate.pem文件转换为弹力城堡格式并存储在Android项目的原始文件夹中.

D:\>"C:\Program Files\Java\jdk1.8.0_121\bin\keytool" -import -alias mqtt-broker -file C:\Users\abcd\Downloads\certificate.pem  -keypass ***** -keystore raw_key_file  -storetype BKS -storepass ***** -providerClass org.bouncycastle.jce.provider.BouncyCastleProvider  -providerpath C:\Users\abcd\Downloads\bcprov-jdk16-1.45.jar

第2步:MQTT客户端设置

mclientPublisher = new MqttAndroidClient(context, mqttBrokerURL,PublisherClientID, new MemoryPersistence());
    if (null != mclientPublisher) 
       {
        MqttConnectOptions options = null;
        options = new MqttConnectOptions();
        options.setMqttVersion(MqttConnectOptions.MQTT_VERSION_3_1_1);
        options.setConnectionTimeout(60);
        options.setKeepAliveInterval(120);
        options.setAutomaticReconnect(true);
        SslUtility.newInstance(context);         
        options.setSocketFactory(SslUtility.getInstance().getSocketFactory
        (R.raw.raw_key_file,"****"));
        options.setCleanSession(true);
       }

第3步:SSL实用程序类

 public class SslUtility {

   private static SslUtility     mInstance = null;
   private Context                mContext = null;
   private HashMap<Integer, SSLSocketFactory> mSocketFactoryMap = new 
   HashMap<Integer, SSLSocketFactory>();




   public SslUtility(Context context) …
