使用XMPP进行文件传输（Extension XEP-0065） [英] File transfer using XMPP (Extension XEP-0065)

问题描述

不确定我为什么转轮套接字失败（调用turnSocketDidFail）。任何人都可以帮我解决这个问题？请指出我在这里做错了什么。我知道有很多这样的问题，我已经检查了所有这些，并且从那里我已经采取了一点帮助。其中一个是Spark，另一个是模拟器。

Not sure why I am getting turn socket failed (turnSocketDidFail called). Anybody can help me in figure out this? Please point me what am I doing wrong here. I know there are lots of question like this and I have already checked all of these and from that I have taken little help already. One of client is Spark and other is simulator.

设置：

服务器：testXyz

Senderjid：user1 @ testXyz

Receiverjid：user2 @ testXyz

Settings:
Server: testXyz
Senderjid: user1@testXyz
Receiverjid: user2@testXyz

XMPPJID *jid = [XMPPJID jidWithString:Receiverjid];
[TURNSocket setProxyCandidates:[NSArray arrayWithObjects:Receiverjid, nil]];
TURNSocket *turnSocket = [[TURNSocket alloc] initWithStream:self.chatManager.xmppStream toJID:jid];
[turnSocket startWithDelegate:self delegateQueue:dispatch_get_main_queue()];

更新

如果我要改变：

[TURNSocket setProxyCandidates：[NSArray arrayWithObjects：Receiverjid，nil]];

to：

[TURNSocket setProxyCandidates：[NSArray arrayWithObjects：Server，nil]] ;

它给了我：

<错误代码=503type =cancel>< service-unavailable xmlns =urn：ietf：params：xml：ns：xmpp-stanzas/>< / error> 。

正如堆栈中的一个问题中所建议的那样，为了解决这个错误，我已经用'user2 @ testXyz / spark'取代了Receiverjid：'user2 @ testXyz'但是我还是得到了相同的错误。

As suggested in one of question on stack to resolve this error I have replaced Receiverjid: 'user2@testXyz' by 'user2@testXyz/spark' but am still getting same error.

推荐答案

不知道在setProxyCandidates中设置什么，但我正在设置我的服务器名称。

Don't know what to set in setProxyCandidates, but I am setting my Server name.

<错误代码=503type =cancel>< service-unavailable xmlns =urn：ietf：params：xml：ns： xmpp-stanzas/>< / error>

解决方案：传递完整的jabber id： username @ domain / resource。
在我的情况下我改变了'user2 @ testXyz / spark;到'user2 @ testXyz / Spark 2.6.3'

我不知道如何找到这些资源参数。我检查了XMPPJID类的资源参数，但它是nil。我通过查看一些控制台日志找到了这些参数。如果有人知道如何从任何xmpp类中找到它，请告诉我。

Solution: Pass full jabber id:username@domain/resource. In my case I have changed 'user2@testXyz/spark; to 'user2@testXyz/Spark 2.6.3'

I don't know how to find these resource parameters. I have checked XMPPJID class's resource parameter but it is nil. I found these parameters by seeing some console logs. If anybody know how to find this from any xmpp class then please let me know.
