在XMPP中使用iOS进行文件传输时出现服务不可用503错误 [英] service-unavailable 503 error for file transfer in XMPP with iOS

问题描述

我正在使用XMPP和iOS进行文件传输.

I am using XMPP with iOS for file transfer.

我正在使用以下代码行发送文件.但是我一直在遇到一个错误，并一直坚持下去.

I am using following lines of code to send file. But I am continuously getting single error and stuck on issue.

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

我已经在应用程序中使用以下代码在两个设备之间发送文件.

I have used following code in app to send file between two devices.

XMPPJID *jid = self.chatUserJID;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                     NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* path = [documentsDirectory stringByAppendingPathComponent:
                  @"aqua.png" ];
UIImage* image = [UIImage imageWithContentsOfFile:path];

XMPPSIFileTransfer *sifiletransfer=[[XMPPSIFileTransfer alloc]init];

[sifiletransfer initiateFileTransferTo:jid withData:UIImagePNGRepresentation(image)];
sifiletransfer.sid = [[self xmppStream] generateUUID];

if ([jid.domain isEqualToString:[self.xmppStream myJID].domain]) {
    [TURNSocket setProxyCandidates:[NSArray arrayWithObjects:jid.domain, nil]];
} else {
    [TURNSocket setProxyCandidates:[NSArray arrayWithObjects:jid.domain,[self.xmppStream myJID].domain, nil]];
}
TURNSocket *socket = [[TURNSocket alloc] initWithStream:[[self appDelegate] xmppStream] toJID:jid];;
[socket startWithDelegate:self delegateQueue:dispatch_get_main_queue()];

文件传输日志如下所示.

Log for file transfer is shown as below.

任何人都可以建议我这个问题可能是什么错误吗?

Can any body please suggest me what can be the mistake because of which this issue is taking place?

我已经完成以下配置以启用文件传输.

I have done following configuration to enable file transfer.

已启用从Openfire进行文件传输. Server -> Server Settings -> File Transfer Settings -> Enable on port number 7777

Enabled file transfer from Openfire. Server -> Server Settings -> File Transfer Settings -> Enable on port number 7777

在Openfire中设置以下服务器属性.

Set following server properties in Openfire.

xmpp.domain             192.168.2.120
xmpp.proxy.enabled      true
xmpp.proxy.externalip   192.168.2.120 / proxy.192.168.2.120 // Tried both
xmpp.proxy.port         7777

如果您有任何想法，我要求您提供帮助.

I request you to help if you have any idea.

提前谢谢！

推荐答案

似乎没有传递带有资源的正确JID. 具有资源的完整JID类似于jsojitra@192.168.2.120/4a0ce4e9. 最后一个特殊的"4a0ce4e9"是应该在JID往返之间的资源.

looks like you haven't passing correct JID with resource. A complete JID with resource looks like jsojitra@192.168.2.120/4a0ce4e9. Last special "4a0ce4e9" are resource which should be in both JID to and from.

您应该拥有

from ="spatil@192.168.2.120/someResourceId"

from="spatil@192.168.2.120/someResourceId"

to ="jsojitra@192.168.2.120/4a0ce4e9

to="jsojitra@192.168.2.120/4a0ce4e9
