默认情况下,我想实施XEP-0012,Stanza.io不支持。
我正在关注如何从其文档中创建插件,但它无法正常工作。
继承我的代码(last.js):
'use strict';
module.exports = function (client) {
client.disco.addFeature('jabber:iq:last');
client.on('jabber:iq:last', function (iq) {
client.sendIq(iq.resultReply({
last: new Date().getTime()
}));
});
client.getLastActivity = function (jid, cb) {
return this.sendIq({
to: jid,
type: 'get',
last: true
}, cb);
};
};
然后我用它:client.use(require('last'))
但是当我调用该函数时,它返回错误bad request
<bad-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/></error>
我错过了什么?
感谢

我们基本上需要创建一个自定义节并将其发送为 iq
this.client.use(this.setCustomMessage.bind(this));
setCustomMessage(client, stanzas) {
const lastActivity = stanzas.define({
name: 'lastActivity',
element: 'query',
namespace: 'jabber:iq:last',
fields: {
seconds: stanzas.utils.attribute('seconds')
}
});
stanzas.withIQ(iq => {
stanzas.extend(iq, lastActivity);
});
}
并获取具有 id
的jid的用户的lastActivitygetLastActivity(userId, cb) {
return this.client.sendIq({
to: 'userId',
type: 'get',
id: 'last',
query: true
}, cb);
}
}
您可以通过两种方式获取上次活动的结果: 要么得到承诺的答复
this.getLastActivity(userId).then(data => {
if (data && data.query && data.query.seconds) {
// Math.round(new Date())-(parseInt(data.query.seconds, 10)*1000)
will give last activity
}
});
或
client.on('iq', data => {
if (data.query && data.query.seconds) {
// Math.round(new Date())-(parseInt(data.query.seconds, 10)*1000)
will give last activity
}
});

module.exports = function (client, stanzas) {
// 1. Create and register our custom `mystanza` stanza type
const helpers = stanzas.utils;
const IqLastActivity = stanzas.define({
name: 'query',
element: 'query',
namespace: 'jabber:iq:last',
fields: {
seconds: helpers.attribute('seconds')
}
});
stanzas.withIq((Iq) => {
stanzas.extend(Iq, IqLastActivity);
});
// eslint-disable-next-line no-param-reassign
client.lastActivityByIq = (data) => {
client.sendIq(data);
};
client.on('iq', (iq) => {
if (iq.query) {
client.emit('iq:last', iq);
}
});
client.on('iq:last', (iq) => {
console.log('iq:last', iq);
});
};
将此代码添加到您的客户端文件
从'./PathToFile/iqLastActivity'导入IqLastActivity;
client.use(IqLastActivity);
