XMPPFramework – 在文件传输中出现错误“405”<not-allowed>

我试图在iOS中使用XMPPFramework实现文件传输。 我正在向名单上的用户发送段落如下。

---

-(void)sendFile { NSString *filePath = fileNameToBeUploaded; CFStringRef fileExtension = (__bridge CFStringRef)[filePath pathExtension]; CFStringRef UTI = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, fileExtension, NULL); CFStringRef MIMEType = UTTypeCopyPreferredTagWithClass(UTI, kUTTagClassMIMEType); CFRelease(UTI); NSString *MIMETypeString = (__bridge_transfer NSString *)MIMEType; NSString *URL = fileNameToBeUploaded; NSError *AttributesError = nil; NSDictionary *FileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:URL error:&AttributesError]; NSNumber *FileSizeNumber = [FileAttributes objectForKey:NSFileSize]; NSArray *splitter = [MIMETypeString componentsSeparatedByString:@"/"]; NSString *extension = [splitter objectAtIndex:1]; NSString *mediaType = @"image"; long FileSize = [FileSizeNumber longValue]; // XMPPUserCoreDataStorageObject *user = [[self appDelegate].xmppRosterStorage userForJID:[XMPPJID jidWithString:self.chatWithUser] xmppStream:[self appDelegate].xmppStream managedObjectContext:[self appDelegate].managedObjectContex_roster]; // Create message self.streamId = [self generateIDWithPrefix:@"ip_"]; self.requestId = [self generateIDWithPrefix:@"jsi_"]; NSXMLElement *si = [NSXMLElement elementWithName:@"si" xmlns:@"http://jabber.org/protocol/si"]; [si addAttributeWithName:@"id" stringValue:self.streamId]; [si addAttributeWithName:@"mime-type" stringValue:MIMETypeString]; [si addAttributeWithName:@"profile" stringValue:@"http://jabber.org/protocol/si/profile/file-transfer"]; NSXMLElement *fileElement = [NSXMLElement elementWithName:@"file" xmlns:@"http://jabber.org/protocol/si/profile/file-transfer"]; [fileElement addAttributeWithName:@"name" stringValue:[fileNameToBeUploaded lastPathComponent]]; [fileElement addAttributeWithName:@"size" stringValue:[NSString stringWithFormat:@"%ld",FileSize]]; [fileElement addAttributeWithName:@"desc" stringValue:@""]; [si addChild:fileElement]; NSXMLElement *feature = [NSXMLElement elementWithName:@"feature" xmlns:@"http://jabber.org/protocol/feature-neg"]; NSXMLElement *x = [NSXMLElement elementWithName:@"x" xmlns:@"jabber:x:data"]; [x addAttributeWithName:@"type" stringValue:@"from"]; NSXMLElement *field = [NSXMLElement elementWithName:@"field"]; [field addAttributeWithName:@"type" stringValue:@"list-single"]; [field addAttributeWithName:@"var" stringValue:@"stream-method"]; NSXMLElement *option = [NSXMLElement elementWithName:@"option"]; NSXMLElement *bs = [NSXMLElement elementWithName:@"value" xmlns:@"http://jabber.org/protocol/bytestreams"]; [option addChild:bs]; [field addChild:option]; [x addChild:field]; [feature addChild:x]; [si addChild:feature]; XMPPJID *toJid = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@/iPhone",self.chatWithUser]]; XMPPIQ *iqtoSend = [XMPPIQ iqWithType:@"set" to:toJid elementID:self.requestId child:si]; if (self.fileInfo) { self.fileInfo = nil; } self.fileInfo = [[FileInfo alloc] initWithFileName:fileNameToBeUploaded mediaType:mediaType mimeType:MIMETypeString size:FileSize localName:fileNameToBeUploaded IQ:[NSString stringWithFormat:@"%@",iqtoSend] fileNameAsSent:fileNameToBeUploaded sender:@""]; [self appDelegate].isSending = YES; [[self appDelegate].xmppStream sendElement:iqtoSend]; } 

控制台显示以下内容

发送节

 SEND: <iq type="set" to="tushar@54.186.107.171/iPhone" id="jsi_9579"> <si xmlns="http://jabber.org/protocol/si" id="ip_4387" mime-type="image/png" profile="http://jabber.org/protocol/si/profile/file-transfer"> <file xmlns="http://jabber.org/protocol/si/profile/file-transfer" name="11392014-143906437.png" size="166688" desc=""/> <feature xmlns="http://jabber.org/protocol/feature-neg"> <x xmlns="jabber:x:data" type="from"> <field type="list-single" var="stream-method"> <option> <value xmlns="http://jabber.org/protocol/bytestreams"/> </option> </field> </x> </feature> </si> </iq>

我的JID是dev1@54.186.107.171。 我想发送文件的用户的JI是tushar@54.186.107.171。

为什么我得到错误405？ 是否需要进行文件传输？ 我错过了什么吗？

纠正以下行

 [x addAttributeWithName:@"type" stringValue:@"from"]; 

同

 [x addAttributeWithName:@"type" stringValue:@"form"]; 

在这里你写了“from”而不是“form”。 有关更多详细信息，请访问以下链接： http : //xmpp.org/extensions/xep-0096.html
