GCM连接错误

Question

我正在尝试使用XMPP（CCS）实现gcm服务器应用程序，但我无法连接到谷歌服务器。我正在尝试中的示例代码http://developer.android.com/google/gcm/ccs.html

当我尝试连接时

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)

我使用服务器密钥作为API密钥（密码）用户名="项目编号"+"@gcm.googleapis.com"

我的项目已列入上游消息白名单被认为关闭的港口在我的工作场所开放。5228、5229和5230用于我的IP。我应该使用哪个Ip打开端口？公共Ip还是另一个？

可能是什么问题？请帮我解决这个问题！提前感谢

Answer 1

您可以从命令行尝试吗"telnet gcm.googleapis.com 5235"

如果你看到"Connected to gcm.l.google.com"-你的防火墙很好。

CCS（第三方服务器使用的XMPP端点）正在使用端口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，不确定您是如何获得的。
