XMPPFramework-错误"405"； <不允许的>在文件传输中 [英] XMPPFramework- Error "405" <not-allowed> in File Transfer

问题描述

我正在尝试使用iOS中的XMPPFramework来实现文件传输.我正在向以下名单中的用户发送节.

I am trying to implement file transfer using XMPPFramework in iOS. I am sending stanzas to user who is in my roster as following.

-(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];

}

我的JID是dev1@54.186.107.171. 我要发送文件的用户的JI是tushar@54.186.107.171.

My JID is dev1@54.186.107.171. JI of user whom I want to send file is tushar@54.186.107.171.

为什么我会收到错误405? 进行文件传输需要任何过程吗?我错过了什么吗?

Why I am getting error 405? Is any process is required to do file transfer? Have I missed something?

推荐答案

更正以下行

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

使用

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

在这里您写的是从"而不是表格".有关更多详细信息，请访问以下链接: http://xmpp.org/extensions/xep-0096. html

Here you have written "from" instead of "form". For more details you can visit following link: http://xmpp.org/extensions/xep-0096.html
