GCM连接错误
我正在尝试使用XMPP（CCS）实现gcm服务器应用程序，我无法连接到谷歌服务器。 我正在尝试http://developer.android.com/google/gcm/ccs.html中的示例代码
当我尝试连接
ccsClient.connect(userName, password); 我收到以下错误
gcm.googleapis.com:5235 Exception: XMPPError connecting to gcm.googleapis.com:5235.; : remote-server-error(502) -- caused by: XMPPError connecting to gcm.googleapis.com:5235.: remote-server-error(502) XMPPError connecting to gcm.googleapis.com:5235. -- caused by: java.net.ConnectException: Connection timed out: connect at org.jivesoftware.smack.XMPPConnection.connectUsingConfiguration(XMPPConnection.java:592) at org.jivesoftware.smack.XMPPConnection.connect(XMPPConnection.java:1010) at SmackCcsClient.connect(SmackCcsClient.java:249) at Sample.main(Sample.java:342) Nested Exception: XMPPError connecting to gcm.googleapis.com:5235.: remote-server-error(502) XMPPError connecting to gcm.googleapis.com:5235. -- caused by: java.net.ConnectException: Connection timed out: connect at org.jivesoftware.smack.XMPPConnection.connectUsingConfiguration(XMPPConnection.java:565) at org.jivesoftware.smack.XMPPConnection.connect(XMPPConnection.java:1010) at SmackCcsClient.connect(SmackCcsClient.java:249) at Sample.main(Sample.java:342) Nested Exception: java.net.ConnectException: Connection timed out: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.connect(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.(Unknown Source) at com.sun.net.ssl.internal.ssl.SSLSocketFactoryImpl.createSocket(Unknown Source) at org.jivesoftware.smack.XMPPConnection.connectUsingConfiguration(XMPPConnection.java:557) at org.jivesoftware.smack.XMPPConnection.connect(XMPPConnection.java:1010) at SmackCcsClient.connect(SmackCcsClient.java:249) at Sample.main(Sample.java:342) Exception in thread "main" java.lang.NoClassDefFoundError: SmackCcsClient$GcmPacketExtension at SmackCcsClient.send(SmackCcsClient.java:130) at Sample.main(Sample.java:357) Caused by: java.lang.ClassNotFoundException: SmackCcsClient$GcmPacketExtension at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 2 more
我使用服务器密钥作为API密钥（密码）和用户名=“项目编号”+“@ gcm.googleapis.com”
我的项目被列入上传消息列表被认为已关闭的端口在我的工作场所开放。 我的IP为5228,5229和5230。 我应该用哪个来打开端口？ 公共IP还是另一个？
可能是什么问题呢？ 请帮我解决这个问题！ 提前致谢
你可以尝试从命令行 – 例如“telnet gcm.googleapis.com 5235”
如果您看到“已连接到gcm.l.google.com” – 您的防火墙就可以了。
CCS（第三方服务器使用的XMPP端点）使用端口5235 – 连接到GCM的android / chrome设备需要5228,5229端口。
AFAIK 5230不是我们的端口之一，不知道你是如何得到它的。
