问题描述
您好，我们已经从 ..我是否必须更改某些内容?还是缺少什么?
解决方案
我遇到了类似的问题.我在Windows 10中安装了openfire serevr.我的代码是
DomainBareJid xmppServiceDomain = JidCreate.domainBareFrom("desktop-urvfr83");//DomainBareJid xmppServiceDomain = JidCreate.domainBareFrom("192.168.1.3");InetAddress addr = InetAddress.getByName("192.168.1.3");XMPPTCPConnectionConfiguration配置= XMPPTCPConnectionConfiguration.builder().setUsernameAndPassword("alir"，"111111").setHostAddress(addr).setResource("phonn").setXmppDomain(xmppServiceDomain).setSecurityMode(ConnectionConfiguration.SecurityMode.disabled).setPort(5222).建造(); ，但无法连接.当我禁用防火墙时，它可以正常工作并连接.
Hello we have downloaded the ejabberd from this. domain is localhost and we have set the xmppDomain as my computer's ip address. I have used the following code for connection
public static final String XMPP_DOMAIN = "localhost";
public static final String XMPP_HOST = "10.0.2.2";//kept for emaulator
//public static final String XMPP_HOST = "192.168.1.152"; //ip of my pc

public static final String XMPP_RESOURCE = "xmppdemo";
public static final boolean XMPP_DEBUG = true;

When I run this code I an receiving the following exception (when tried to run from emulator)
SMACKException: The following addresses failed: '10.0.2.2:5222' failed because: /10.0.2.2 exception: java.net.SocketTimeoutException: failed to connect to /10.0.2.2 (port 5222) from /192.168.232.2 (port 34922) after 30000ms
when tried to run from my device I kept HOST_NAME as my pc's ip address, but then I am receiving the following error
E/XMPPHandler: SMACKException: The following addresses failed: '192.168.1.152:5222' failed because: /192.168.1.152 exception: java.net.SocketTimeoutException: connect timed out
When I installed ejabberd on my pc then I received the following Access Control List page.. Should I have to change something?? Or missing something?
解决方案
I had similar problem. I have openfire serevr installed in windows 10.My code was
DomainBareJid xmppServiceDomain = JidCreate.domainBareFrom("desktop-urvfr83");
//DomainBareJid xmppServiceDomain = JidCreate.domainBareFrom("192.168.1.3");
InetAddress addr = InetAddress.getByName("192.168.1.3");
XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
.setUsernameAndPassword("alir", "111111")
.setHostAddress(addr)
.setResource("phonn")
.setXmppDomain(xmppServiceDomain)
.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
.setPort(5222)
.build();
but it could not connect. When I disabled the firewall it worked correctly and connected.
