【问题描述】：

您知道任何不推荐使用的 javascript XMPP 客户端库吗？我尝试过的库是：

node-xmpp-client

2.@xmpp/client

我在使用@xmpp/client 时遇到了困难。请看下面的代码和错误。

结果：用户登录后打印“我在线”。

如果您知道任何学习资源，请提供任何学习资源

代码：

 var app = require('express')();
 //const xmpp = require('xmpp-ftw');
 //const BuddyCloud = require('xmpp-ftw-buddycloud');

 var server = require('http').createServer(app);

 var io = require('socket.io').listen(server);

 server.listen(process.env.PORT || 3000);

 app.get('/', function(req, res){
 res.sendFile(__dirname + '/index.html');
 });


 const {client, xml} = require('@xmpp/client')

const xmpp = client({
     service: 'ws://domain.com:5280/xmpp-websocket',
     domain:'domain.com',
     username: 'test',
     password:'pa$$word'
 });

 xmpp.on('online', ()=>{
 console.log('I am Online');
 });

 xmpp.on('stanza', async stanza => {
    if (stanza.is('message')) {
      await xmpp.send(xml('presence', {type: 'unavailable'}))
      await xmpp.stop()
    }
  });


 xmpp.start();

错误：

韵律上的位置块：

}

【问题讨论】：

404 错误表明服务器不期望该路径上的 websockets 请求。你用的是什么服务器？它的配置文件里有什么？
@legoscia 我正在使用韵律 v0.9.10。我刚刚更新了位置块（请参阅已编辑的问题），现在我从模块管理器中收到一个错误，即无法安装 websocket 模块

标签： javascript html node.js websocket xmpp

【解决方案1】：

node-xmpp-client 运行良好

我的 nginx 配置

stream {
map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

upstream websocket {
    server localhost:5280;
}

server {
    listen 80;
    location / {
        proxy_pass http://websocket;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }
}
}

我使用另一个子域来访问韵律。尝试不使用nginx代理直接连接，看看问题是来自js/nginx还是prosody。
