XMPPFramework - 檢索Openfire郵件歸檔文件

Question

花了幾小時試圖解決這個問題，我很難過！

試圖抓住我的OpenFire服務器上的2個用戶之間的聊天記錄，我看到我需要插件來做到這一點。

所以，我安裝我的Openfire服務器上的「開放檔案」插件，併發送下面的XML（按照XMPP-0136協議文檔）：

<iq type="get" id="page1"> 
    <retrieve xmlns="urn:xmpp:archive" with="username@server.com" start="1469-07-21T02:56:15Z"> 
     <set xmlns="http://jabber.org/protocol/rsm"> 
     <max>100</max> 
     </set> 
    </retrieve> 
</iq> 

在代碼中，這是通過以下實現：

NSXMLElement *iQ = [NSXMLElement elementWithName:@"iq"]; 
[iQ addAttributeWithName:@"type" stringValue:@"get"]; 
[iQ addAttributeWithName:@"id" stringValue:@"page1"]; 

NSXMLElement *retrieve = [NSXMLElement elementWithName:@"retrieve"]; 
[retrieve addAttributeWithName:@"xmlns" stringValue:@"urn:xmpp:archive"]; 
[retrieve addAttributeWithName:@"with" stringValue:@"username@server.com"]; 
[retrieve addAttributeWithName:@"start" stringValue:@"1469-07-21T02:56:15Z"]; 

NSXMLElement *set = [NSXMLElement elementWithName:@"set"]; 
[set addAttributeWithName:@"xmlns" stringValue:@"http://jabber.org/protocol/rsm"]; 
NSXMLElement *max = [NSXMLElement elementWithName:@"max"]; 
max.stringValue = @"100"; 
[set addChild:max]; 

[retrieve addChild:set]; 
[iQ addChild:retrieve]; 

[[[self appDelegate] xmppStream] sendElement:iQ]; 

它返回以下錯誤：

<iq xmlns="jabber:client" type="error" id="page1" to="username@server.com"> 
    <error code="404" type="cancel"> 
     <item-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/> 
    </error> 
</iq> 

我的Xcode項目可以成功地向用戶發送/接收消息我試圖接收聊天記錄，所以我真的不知道我在做什麼錯誤。此外，插件使我能夠通過聊天消息（通過OpenFire管理員）搜索成功的結果，因此它似乎在工作並存儲消息。

任何幫助，將不勝感激。謝謝！

XMPPFramework實現XEP-0136。您是否嘗試過使用​​來設置首選項或將服務器的存檔同步到客戶端？

如果您正在查找聊天記錄，我認爲您必須將郵件保存到核心數據並從那裏檢索。對於使用XMPPFramework內置功能保存數據，你必須使用此代碼：

XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance]; 
NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext]; 

xmppMessageArchivingStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance]; 
xmppMessageArchivingModule = [[XMPPMessageArchiving alloc] initWithMessageArchivingStorage:xmppMessageArchivingStorage]; 
[xmppMessageArchivingModule activate:xmppStream]; 
[xmppMessageArchivingModule addDelegate:self delegateQueue:dispatch_get_main_queue()]; 

現在您已經檢索該從核心數據消息：

-(void)loadarchivemsg 
{ 
    XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance]; 
    NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext]; 
    NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPMessageArchiving_Message_CoreDataObject" 
                 inManagedObjectContext:moc]; 
    NSFetchRequest *request = [[NSFetchRequest alloc]init]; 

    NSString *predicateFrmt = @"bareJidStr like %@ "; 
    NSPredicate *predicate = [NSPredicate predicateWithFormat:predicateFrmt, chatWithUser]; 
    request.predicate = predicate; 
    NSLog(@"%@",[[NSUserDefaults standardUserDefaults] stringForKey:@"kXMPPmyJID"]); 
    [request setEntity:entityDescription]; 
    NSError *error; 
    NSArray *messages_arc = [moc executeFetchRequest:request error:&error]; 

    [self print:[[NSMutableArray alloc]initWithArray:messages_arc]]; 
} 

-(void)print:(NSMutableArray*)messages_arc{ 
    @autoreleasepool { 
     for (XMPPMessageArchiving_Message_CoreDataObject *message in messages_arc) { 
      NSXMLElement *element = [[NSXMLElement alloc] initWithXMLString:message.messageStr error:nil]; 
      NSLog(@"to param is %@",[element attributeStringValueForName:@"to"]); 

      NSMutableDictionary *m = [[NSMutableDictionary alloc] init]; 
      [m setObject:message.body forKey:@"msg"]; 

      if ([[element attributeStringValueForName:@"to"] isEqualToString:chatWithUser]) {    
       [m setObject:@"you" forKey:@"sender"]; 
      } 
      else { 
       [m setObject:chatWithUser forKey:@"sender"]; 
      } 

      [messages addObject:m]; 

      NSLog(@"bareJid param is %@",message.bareJid); 
      NSLog(@"bareJidStr param is %@",message.bareJidStr); 
      NSLog(@"body param is %@",message.body); 
      NSLog(@"timestamp param is %@",message.timestamp); 
      NSLog(@"outgoing param is %d",[message.outgoing intValue]); 
      NSLog(@"***************************************************"); 
     } 
    } 
}

請有在細節詩節詳細：https://stackoverflow.com/a/29097289/2225439

它是平臺獨立的，只需要瞭解Stanza的結構，並且可以根據您正在使用的庫創建。

這是您需要發送以獲取存檔郵件的Stanza系列。欲瞭解更多的細節，你可以檢出XEP 0136（http://xmpp.org/extensions/xep-0136.html#manual）

當你在要求提起始標記則具有這就是爲什麼它返回錯誤代碼「404」或「500」的確切時間戳記聊天匹配的列表。我從我的請求中刪除了開始標記並編寫了以下代碼，它將返回與用戶的整個聊天記錄。

NSXMLElement *iq1 = [NSXMLElement elementWithName:@"iq"]; 
[iq1 addAttributeWithName:@"type" stringValue:@"get"]; 
[iq1 addAttributeWithName:@"id" stringValue:@"pk1"]; 

NSXMLElement *retrieve = [NSXMLElement elementWithName:@"retrieve" xmlns:@"urn:xmpp:archive"]; 

[retrieve addAttributeWithName:@"with" stringValue:@"rahul@vishals-mac-pro.local"]; 
NSXMLElement *set = [NSXMLElement elementWithName:@"set" xmlns:@"http://jabber.org/protocol/rsm"]; 
NSXMLElement *max = [NSXMLElement elementWithName:@"max" stringValue:@"100"]; 

[iq1 addChild:retrieve]; 
[retrieve addChild:set]; 
[set addChild:max]; 
[[[self appDelegate] xmppStream] sendElement:iq1]; 

這裏，這將在當前登錄的用戶拉胡爾和用戶之間的XML響應返回整個聊天記錄。
