我正在一个项目中工作，该项目在wordpress后端（用于存储消息，帖子），用于用户交互的有角度前端（Angluar 6x）和用于从Web应用程序内部进行聊天通信的eJabber服务器之间进行复杂的交互。 >
为了实现这一点，我正在尝试将strophe.js集成到Angular框架中。
我使用的身份验证方法很复杂。当新用户通过适当的（角度）形式向wordpress后端注册时，我已经设置了钩子，这些钩子也自动将新用户订阅到本地eJabberd服务器。为了管理身份验证，为了避免最终用户输入两次其凭据，我在eJabberd中设置了一个自定义extauth脚本（基于this），该脚本与自定义的wordpress rest API端点（我正在使用JWT。）
extauth脚本运行正常，我可以使用各种聊天客户端（Adium，Apple的Messages等）成功连接到本地eJabberd服务器。
我也可以从我的Web应用程序中连接（如前所述，使用strophe）。
这是我用来管理连接的代码段（ChatPanel.Service.ts）：
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Strophe, $pres } from 'strophe.js';
import { EJABBERD } from 'app/api/api.module';
var chatPanelServiceInstance: any = null;
@Injectable()
export class ChatPanelService
{
contacts: any[];
chats: any[];
user: any;
client: any;
// Private
private _xmppConnectionsString: String = "ws://" + EJABBERD.host + ":5280/ws";
private _xmppConnection: any = null;
/**
* Constructor
*/
constructor(
)
{
chatPanelServiceInstance = this;
Strophe.log = (level: any, msg: string) => { console.log(level + ": " + msg); };
}
/**
* Log into eJabberd
*
* @param {string} jid user name
* @param {string} password password (actually, the user token)
*/
login(jid: string, password: string): void
{
if ( ! this._xmppConnection ) {
this._xmppConnection = new Strophe.Connection( this._xmppConnectionsString , {'keepalive': true});
}
this._xmppConnection.connect(jid+'@'+EJABBERD.host, password, this._onConnect);
}
/**
* Disconnect from eJabberd
*/
logOut(): void
{
if ( this._xmppConnection ) {
this._xmppConnection.options.sync = true;
this._xmppConnection.flush();
this._xmppConnection.disconnect("logout");
this._xmppConnection = null;
}
}
/**
* eJabberd XMPP message Handler
* @param {string} msg Message received
*/
private _onMessage(msg: string): boolean
{
console.log("eJabber Msg: " + msg);
return true;
}
/**
* eJabberd connection Handler
* @param {any} status connection result
*/
private _onConnect(status: any): void
{
switch (status) {
case Strophe.Status.CONNECTING:
console.log("Connecting to eJabberd...");
break;
case Strophe.Status.CONNFAIL:
console.log("eJabberd connection failed!");
break;
case Strophe.Status.DISCONNECTING:
console.log("Disconnecting from eJabberd...");
break;
case Strophe.Status.DISCONNECTED:
console.log("Disconnected from eJabberd");
break;
case Strophe.Status.CONNECTED:
//handler function [ onMessage() ] will be called when the user recieves a new message
chatPanelServiceInstance._xmppConnection.addHandler(chatPanelServiceInstance._onMessage, null, 'message');
//Setting our presence in the server. so that everyone can know that we are online
chatPanelServiceInstance._xmppConnection.send($pres().tree());
console.log("eJabberd connected!");
break;
case Strophe.Status.AUTHENTICATING:
console.log("eJabberd authenticating...");
break;
case Strophe.Status.AUTHFAIL:
console.log("eJabberd authentication failed!");
break;
case Strophe.Status.ERROR:
console.log("eJabberd generic connection error!");
break;
case Strophe.Status.ATTACHED:
console.log("eJabberd connection attached!");
break;
case Strophe.Status.REDIRECT:
console.log("eJabberd connection redirected!");
break;
case Strophe.Status.CONNTIMEOUT:
console.log("eJabberd connection timeout!");
break;
default:
console.log("eJabberd: Unknow connection status");
}
}
注销后尝试重新连接到服务器时会出现问题。
当我从Web应用程序注销（即从chatpanel.service调用logout（））时，如果尝试再次登录，则ejabber服务器未收到任何响应。显然，服务器停止侦听来自strophe的任何进一步请求。
我已经尝试过websockets和BOSH。最终结果是相同的。

如您所见，使用Bosh，调试器告诉我服务器没有提供任何合适的身份验证方法。
显然，服务器不再侦听传入的连接请求。但是，奇怪的是，如果我重新启动服务器，则重新连接成功。看起来strophe.js甚至在断开连接过程完成后仍保持打开状态，关闭它的唯一方法是停止服务器。
我不确定这是strophe.js问题还是ejabberd config问题，但是我更倾向于考虑客户端问题（或者我的代码中缺少的东西），因为外部客户端可以完美地连接到服务器。
任何提示将不胜感激。
答案 0 :(得分：1)
知道了。
我在这里发帖，作为针对这些问题的答案，面临类似的问题。
问题不是Strophe.js，而是jabber服务器的配置。问题是缓存。
从eJabber文档（here）
auth_use_cache：false | true：从ejabberd 17.06开始，缓存具有 进行了彻底的大修。一组新的而不是extauth_cache 变量描述缓存行为，默认值现在是 真正。请注意，缓存会影响维护能力 每个帐户有多个密码。所以如果您的身份验证机制 支持应用程序专用密码，必须禁用缓存。
eJabberd被配置为在适用的所有情况下默认使用缓存。
因为，当我从Web应用程序注销时，我使用于身份验证的旧JSON Web令牌无效，因此ejabber会根据缓存的值检查新的凭据，从而发现不匹配。
解决方案是禁用这样的缓存（在ejabberd.yml中）auth_use_cache: false
