Question

我是gcm的新手，我尝试使用Smack API连接到GCM的Cloud Connection Server（XMPP）。一开始没事，我的代码：

uid = "123456789";
apiKey = "A**************B";
XMPPTCPConnectionConfiguration.Builder config;
config.setSocketFactory(SSLSocketFactory.getDefault());
    config = XMPPTCPConnectionConfiguration.builder();
    config.setUsernameAndPassword(uid,apiKey);
    config.setServiceName("gcm.googleapis.com");
    config.setHost("gcm.googleapis.com");
    config.setPort(5235);
    config.setDebuggerEnabled(true);
    mConnection = new XMPPTCPConnection(config.build());
    mConnection.setPacketReplyTimeout(10000);
    try {
         mConnection.connect();
         mConnection.login();
        }
   catch (SmackException | IOException | XMPPException e) {
            System.out.println("Exception at SmackCcsClient.init()");
            e.printStackTrace();
        }

但我无法通过最初的握手过程。我首先使用了一些虚拟随机GCMID来测试下游消息，它显示在smack调试窗口中，但稍后，相同的代码在以下xml提示后显示为原始发送数据包：

<stream:stream xmlns='jabber:client' to='gcm.googleapis.com'  xmlns:stream='http://etherx.jabber.org/streams' version='1.0' xml:lang='en'>

我试过

mConnection.login(uid+"@gcm.googleapis.com",apiKey);//even though i assume its next step of the handshake.

控制台会输出以下错误：

请帮助我解决这个问题，因为我真的很困惑，无处可去。请告诉我一种方法来检查我的xml请求是否到达谷歌。

使用SMACK库版本4.1.1

使用config.setSecurityMode（ConnectionConfiguration.SecurityMode.ifpossible）;解决了我的问题。它定义了要使用的连接的配置。如果服务器支持相同的连接，则打开TLS。

参考：http://www.igniterealtime.org/builds/smack/docs/latest/javadoc/org/jivesoftware/smack/ConnectionConfiguration.html

config = XMPPTCPConnectionConfiguration.builder();
config.setSecurityMode(ConnectionConfiguration.SecurityMode.ifpossible);
        config.setSocketFactory(SSLSocketFactory.getDefault());
        config.setUsernameAndPassword(uid,apiKey);
        config.setServiceName("gcm.googleapis.com");
        config.setHost("gcm.googleapis.com");
        config.setPort(5235);
        config.setDebuggerEnabled(true);
            mConnection = new XMPPTCPConnection(config.build());
            mConnection.setPacketReplyTimeout(10000);

            try {
                mConnection.connect();

希望它有所帮助。

GCM使用smack库NoResponseException：在回复超时内没有收到响应
