Question

我正在尝试创建可以从浏览器控制的XMPP客户端。我正在使用SleekXMPP作为XMPP客户端和网站烧瓶，所以我可以将信息从XMPP服务器传递到我的XMPP客户端到我的网站前端。如果我使用纯烧瓶，我需要轮询我的服务器以获取更多更新，我宁愿将服务器推送到我的客户端。

我遇到线程问题。连接到服务器工作正常。但是当我断开连接时，我得到一个错误，表明3个线程无法被杀死。如何断开连接时杀死这些线程？或者他们为什么不被杀？或者我应该使用更好的设置？

谢谢！

错误：

DEBUG    Event triggered: session_end
DEBUG    Waiting for 3 threads to exit.
DEBUG    Finished exiting event runner thread after early termination from disconnect() call. 3 threads remain.

这是我的python脚本。

import eventlet
eventlet.monkey_patch()

from flask import Flask, render_template
from flask_socketio import SocketIO, emit, disconnect
import sleekxmpp
import logging

app = Flask(__name__)
app.debug = True
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app)

logging.basicConfig(level=logging.DEBUG, format='%(levelname)-8s %(message)s')


class XMPPClient(sleekxmpp.ClientXMPP):

    def __init__(self, full_jid, pwd):

        self.full_jid = full_jid
        self.pwd = pwd
        sleekxmpp.ClientXMPP.__init__(self, self.full_jid, self.pwd)
        self.HOST = "XXX"
        self.PORT = "XXX"

    def conn(self):
        self.connect(address=(self.HOST, self.PORT))
        self.process(threaded=True)

    def disconn(self):
        self.disconnect(wait=True, send_close=False)

@app.route('/')
def index():
    return render_template('index.html')

@socketio.on('socket_connect', namespace='/vibe')
def _socket_connect():
    xmpp_client.conn()
    return ""

@socketio.on('socket_disconnect', namespace='/vibe')
def _socket_disconnect():
    xmpp_client.disconn()
    return ""


if __name__ == '__main__':
    xmpp_client = XMPPClient(full_jid="XXX", pwd="XXX")
    socketio.run(app)

对于我的前端

        });

SleekXMPP和Flask Socketio悬挂线程
