javascript - ejabberd MAM 不适用于 Strophe js

转载作者：行者123 更新时间：2023-11-30 16:44:44

即使在用户注销和登录后，我也试图显示两个用户之间的对话。我的意思是当 user1 注销并再次登录时，他应该看到与 user2 进行的对话。我正在使用 Ejabberd XMPP 服务器和 Strophe Js 来检索消息。

当我发现这个 strophe.mam.js插件来执行此操作但引发错误并且无法获取消息。

这是我的代码:

function onConnect(status)
    {
        // Functions runs while users trys to login to the XMPP server
        var iq = null;

        switch (status)
        {
            case Strophe.Status.CONNECTING:
                log('Connecting.');
                break;
            case Strophe.Status.CONNFAIL:
                log('Failed to connect.');
                $('#connect').get(0).value = 'connect';
                break;
            case Strophe.Status.DISCONNECTING:
                log('Disconnecting.');
                break;
            case Strophe.Status.DISCONNECTED:
                log('Disconnected.');
                $('#connect').get(0).value = 'connect';
                break;
            case Strophe.Status.CONNECTED:
                log('Connected.');
                connection.addHandler(onMessage, null, 'message', null, null,  null);
                connection.addHandler(onPresence, null, 'presence', null, null, null);

                iq = $iq({type: 'get'}).c('query', {xmlns: 'jabber:iq:roster'});
                connection.sendIQ(iq, onRoster);

                break;
            default:
                break;
        }
    }

function onMessage(msg) {
    debugger;
    var fromJid = msg.getAttribute("from"),
        bareFromJid = Strophe.getBareJidFromJid(fromJid),
        type = msg.getAttribute("type"),
        elems = msg.getElementsByTagName("body");

    if (type == "chat" && elems.length > 0) {
        var body = elems[0],
            message = Strophe.getText(body);

        showMessage(bareFromJid + ": " + message);
              connection.mam.query("yashwanth@localhost", {
  "with": bareFromJid,
  onMessage: function(message) {
            console.log("Message from " + bareFromJid,
                ": " + message);
            return true;
  },
  onComplete: function(response) {
            console.log("Got all the messages");
  }
    });
    }

    return true;
}

function send() {
    // Handles with sending the message
    var to = $('#to-jid').get(0).value,
        myBareJid = Strophe.getBareJidFromJid(connection.jid);
        message = $('#message').get(0).value,
        reply = $msg({to: to, type: 'chat'})
            .c("body")
            .t(message);

    connection.send(reply.tree());
    showMessage(myBareJid + ": " + message);
}

$(document).ready(function () {
    connection = new Strophe.Connection(BOSH_SERVICE);
    messagebox = $("#messages");
    messagebox.val("");
    logbox = $("#log-messages");
    logbox.val("");
    rosterbox = $("#roster");
    rosterbox.val("");
    connection.rawInput = function (data) { log('RECV: ' + data); };
    connection.rawOutput = function (data) { log('SEND: ' + data); };

    Strophe.log = function (level, msg) { log('LOG: ' + msg); };

    login();
    $('#send').bind('click', send);
});

所以每当用户收到消息时，控制台中都会有一些东西。但它在我的日志中返回了这个错误

RECV: <body xmlns='http://jabber.org/protocol/httpbind'><iq xmlns='jabber:client' 
from='yashwanth@localhost' to='yashwanth@localhost/22064184271436881211352579' 
id='yashwanth@localhost' type='error'><query xmlns='urn:xmpp:mam:0'><x xmlns='jabber:x:data'><field 
var='FORM_TYPE'><value>urn:xmpp:mam:0</value></field><field var='with'>
<value>shabda@localhost</value></field></x><set xmlns='http://jabber.org/protocol/rsm'/></query>
<error code='400' type='modify'><bad-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/></error>
</iq></body>

请帮我解决这个问题

最佳答案

您的 MAM 查询格式不正确。

您在具有 xmlns jabber:x:data 功能的 x 元素上缺少属性 type="submit"。 XEP-0004 Data Forms 中的类型是强制性的

你的智商应该是:

<iq type='set' id='juliet1'>
  <query xmlns='urn:xmpp:mam:0'>
    <x xmlns='jabber:x:data' type='submit'>
      <field var='FORM_TYPE' type='hidden'>
        <value>urn:xmpp:mam:0</value>
      </field>
      <field var='with'>
        <value>shabda@localhost</value>
      </field>
    </x>
    <set xmlns='http://jabber.org/protocol/rsm'/>
  </query>
</iq>
