objective-c - 成员(member)无法在 muc room 中获取成员(member)列表

标签 objective-c xmpp ejabberd xmppframework multiuserchat

我正在使用 IOS XMPPFramework 作为我们的聊天应用程序，我正在创建群组并使用以下代码添加所选成员，并且收件人成功加入该群组。 如果我查询该组管理员的成员列表，成功检索该组的成员，但成员无法获取相同的列表，而是收到以下错误:

<iq xmlns="jabber:client" from="<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="7446414444474047434446424734171b1a121106111a17115a171c15005a191111150404075a171b195a0006" rel="noreferrer noopener nofollow">[email protected]</a>" to="<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d1e0e7e4e1e2e2e0e3e7e1e191b2b9b0a5ffbcb4b4b0a1a1a2ffb2bebcffa5a3" rel="noreferrer noopener nofollow">[email protected]</a>/15323458207749806891286" id="FF691FF5-D12B-4BAA-AB19-84E7A2B945D4" type="error"><query xmlns="http://jabber.org/protocol/muc#admin"><item affiliation="member"/></query><error code="403" type="auth"><forbidden xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/><text xmlns="urn:ietf:params:xml:ns:xmpp-stanzas">Administrator privileges required</text></error></iq>

您可以在下面找到创建和邀请代码:

- (void)xmppRoom:(XMPPRoom*)sender didFetchMembersList:(NSArray *)items
{
    CLS_LOG(@"Received MemberList: %@",items);
    if (sender.inviteMemberList) {
        if ([sender.inviteMemberList count]) {

            for (NSString *user in sender.inviteMemberList) {
                [sender inviteUser:[XMPPJID jidWithString:user] withMessage:nil];
            }


            CLS_LOG(@"Adding Members To Group %@",sender.inviteMemberList);
            XMPPIQ *addMemberIQ = [XMPPIQ addMembersToGroup:sender.inviteMemberList withElementId:[self generateMessageID] andNick:sender.nickName andGroupJid:[sender.roomJID bare]];
            CLS_LOG(@"Sending IQ To Add Member: %@",addMemberIQ);
            [xmppStream sendElement:addMemberIQ];
            sender.inviteMemberList = nil;
        }
    }


}

+ (nonnull instancetype) addMembersToGroup:(NSArray *)memberList withElementId:(NSString*)elementId andNick:(NSString*)nick andGroupJid:(NSString*)groupJid
{
    NSXMLElement *queryElement = [self elementWithName:@"query" xmlns:XMPPMUCAdminNamespace];

    for (NSString *member in memberList) {
        NSXMLElement *itemElement = [self elementWithName:@"item"];
        [itemElement addAttributeWithName:@"affiliation" stringValue:@"member"];
        [itemElement addAttributeWithName:@"jid" stringValue:member];

        [queryElement addChild:itemElement];
    }


    return [self iqWithType:@"set" to:[XMPPJID jidWithString:groupJid] elementID:elementId child:queryElement];
}

你能帮我解决这个问题吗？

[编辑2:] 我已经更改了我的代码，如下面的代码所示。我也做了和你一样的配置，但结果还是一样。我在服务器端遗漏了一些东西吗？

- (void)xmppRoom:(XMPPRoom *)sender didFetchConfigurationForm:(NSXMLElement *)configForm{

        NSXMLElement *newConfig = [configForm copy];
        NSArray* fields = [newConfig elementsForName:@"field"];
        for (NSXMLElement *field in fields) {
            NSString *var = [field attributeStringValueForName:@"var"];

            if ([var isEqualToString:@"muc#roomconfig_persistentroom"]) {
                [field removeChildAtIndex:0];
                [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];

            }else if ([var isEqualToString:@"muc#roomconfig_roomname"]){
                [field removeChildAtIndex:0];
                [field addChild:[NSXMLElement elementWithName:@"value" stringValue:sender.groupName]];

            }
            else if ([var isEqualToString:@"muc#roomconfig_publicroom"]){
                [field removeChildAtIndex:0];
                [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"0"]];
            }
            else if ([var isEqualToString:@"muc#roomconfig_whois"]) {
                [field removeChildAtIndex:0];
                [field insertChild:[NSXMLElement elementWithName:@"value" stringValue:@"anyone"] atIndex:0];
            }
            else if ([var isEqualToString:@"muc#roomconfig_allow_subscription"]) {
                [field removeChildAtIndex:0];
                [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
            }
            else if ([var isEqualToString:@"muc#roomconfig_membersonly"]){
              [field removeChildAtIndex:0];
              [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
            }
            else if ([var isEqualToString:@"public_list"]){
                [field removeChildAtIndex:0];
                [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
            }
            else if ([var isEqualToString:@"muc#roomconfig_allowinvites"]){
                [field removeChildAtIndex:0];
                [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
            }
        }
        CLS_LOG(@"Sending Configuration: %@",newConfig);
        [sender configureRoomUsingOptions:newConfig];


        if (sender.inviteMemberList) {
            CLS_LOG(@"Adding Members To Group %@",sender.inviteMemberList);
            XMPPIQ *addMemberIQ = [XMPPIQ addMembersToGroup:sender.inviteMemberList withElementId:[self generateMessageID] andNick:sender.nickName andGroupJid:[sender.roomJID bare]];
            CLS_LOG(@"Sending IQ To Add Member: %@",addMemberIQ);
            [xmppStream sendElement:addMemberIQ];
            [sender fetchMembersList];

        }

}

- (void)xmppRoom:(XMPPRoom*)sender didFetchMembersList:(NSArray *)items{

    CLS_LOG(@"Fetched Members: %@",items);

    if (sender.inviteMemberList) {
        if ([sender.inviteMemberList count]) {

            for (NSString *user in sender.inviteMemberList) {
                [sender inviteUser:[XMPPJID jidWithString:user] withMessage:nil];
            }


            sender.inviteMemberList = nil;
        }
    }

}

最佳答案

确保在配置房间时将 muc#roomconfig_whois 设置为 anyone。

 <field
          label='Who May Discover Real JIDs?'
          type='list-single'
          var='muc#roomconfig_whois'>
        <option label='Moderators Only'>
          <value>moderators</value>
        </option>
        <option label='Anyone'>
          <value>anyone</value>
        </option>
  </field>

[编辑2]:

我想我应该弄清楚出了什么问题。在您的代码中，您首先邀请了用户，然后将他们添加为成员。

您可以尝试反转流程吗？先全部添加为成员(member)，然后再邀请。否则，当用户收到邀请时，可能尚未在 Xmpp Server 上设置成员。

这是我所做的:

  • 加入房间(如果房间不存在，服务器将创建它)。
  • 在xmppRoomDidCreate中，获取配置表单。
  • 发送配置表单，然后立即添加所有成员。
  • 在 didConfigure 中发送邀请。

流程有点慢，我建议您将设置添加为 mod_muc 中的默认设置。只需确保在发送邀请之前添加成员即可。

正如您所看到的，这些项目存在一些差异:

  • muc#roomconfig_publicroom
  • 公共(public)列表
  • muc#roomconfig_moderatedroom
  • muc#roomconfig_allowinvites

我尝试将“muc#roomconfig_moderatedroom”设置为1，但所有成员仍然可以获得成员列表。不确定你这边发生了什么。

关于objective-c - 成员(member)无法在 muc room 中获取成员(member)列表，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40574609/
