Question

所有代码在我的本地计算机上都可以正常运行，而不是在Heroku上。已经阅读了github上的许多问题/ Flask-socketio上的其他错误，似乎没有任何作用。

使用eventlet设置时，我使浏览器运行了大约20分钟，我看到.on（'connect'）正常运行，但代码的其他部分均未运行。

这是我当前的procfile：

web: gunicorn -k geventwebsocket.gunicorn.workers.GeventWebSocketWorker -w 1 --chdir nickdima wsgi:app
heroku features:enable http-session-affinity

我也曾用gevent尝试过这个：

web: gunicorn -k geventwebsocket.gunicorn.workers.GeventWebSocketWorker -w 1 --chdir nickdima wsgi:app

我也尝试通过eventlet来访问此个人资料：

web: gunicorn -k eventlet wsgi:app

以及此带有eventlet的配置文件：

web: gunicorn --worker-class eventlet -w 1 --chdir nickdima wsgi:app

这是我当前的requirements.txt文件：

我也尝试过使用gevent：

gevent-socketio==0.3.6
gevent-websocket==0.10.1

python-socketio==2.0.0
six==1.11.0
Werkzeug==0.14.1

我也尝试使用gunicorn 18.0.0而不是19.x来尝试eventlet / gevent。

这是代码的javascript部分：

player_id = Math.round(Math.random() * 5000);
your_sock = io.connect('http://' + document.domain + ':' + location.port);
your_sock.on('connect', function(){
    your_sock.emit('player_connect', {'id': player_id});
    console.log('I have connected with ID ' + player_id);
});

your_sock.on('what_player', function(data){
    console.log('recieved player number ' + data['player_number']);
    if(data['id'] == player_id){
        players[player_id] = {};
        if(data['player_number'] == 1){
            players[player_id]['num'] = data['player_number'];
            players[player_id]['x'] = 10;
            players[player_id]['y'] = 50;
        } else {
            players[player_id]['num'] = data['player_number'];
            players[player_id]['x'] = 375;
            players[player_id]['y'] = 50;
        }
    }
});

这是代码的python Flask部分

@socketio.on('connect')
def handle_connect():
    print('Player connected')

@socketio.on('player_connect')
def handle_player_connect(data):
    print('received player_connect event')
    data_base = get_db()
    if data_base['count'] == 0:
        data_base[data['id']] = {'player_number': 1}
        data_base[data['id']]['x'] = 10
        data_base[data['id']]['y'] = 50
        data_base['count'] += 1
        socketio.emit('what_player', {'id': data['id'], 'player_number': data_base['count']})
    elif data_base['count'] == 1:
        data_base[data['id']] = {'player_number': 2}
        data_base[data['id']]['x'] = 375
        data_base[data['id']]['y'] = 50
        data_base['count'] += 1
        socketio.emit('what_player', {'id': data['id'], 'player_number': data_base['count']})

        #all players connected
        print('SENDING ALL PLAYERS CONNECTED SIGNAL')
        socketio.emit('all_players', data_base)

截至2018-09-05的新会议--------------------- 与9/4更新相同的requirements.txt

新procfile：

web: gunicorn --worker-class eventlet -w 1 --no-sendfile --log-level=DEBUG --log-file=- --preload --chdir nickdima wsgi:app

不再看到内容不匹配错误，并且我的控制台正在记录一条消息，该消息仅在套接字通过以下代码连接时才能运行：

player_id = Math.round(Math.random() * 5000);
your_sock = io.connect('http://' + document.domain + ':' + location.port + '/');  //io.connect('');  //io.connect('http://' + document.domain + ':' + location.port);
your_sock.on('connect', function(){
    your_sock.emit('player_connect', {'id': player_id});
    console.log('I have connected with ID ' + player_id);
});

但是服务器没有收到'player_connect'发射信号：

@socker.on('player_connect')
def handle_player_connect(data):
    print('received player_connect event')
    data_base = get_db()
    if data_base['count'] == 0:
        data_base[data['id']] = {'player_number': 1}
        data_base[data['id']]['x'] = 10
        data_base[data['id']]['y'] = 50
        data_base['count'] += 1
        socker.emit('what_player', {'id': data['id'], 'player_number': data_base['count']})
    elif data_base['count'] == 1:
        data_base[data['id']] = {'player_number': 2}
        data_base[data['id']]['x'] = 375
        data_base[data['id']]['y'] = 50
        data_base['count'] += 1
        socker.emit('what_player', {'id': data['id'], 'player_number': data_base['count']})

        #all players connected
        print('SENDING ALL PLAYERS CONNECTED SIGNAL')
        socker.emit('all_players', data_base)

Heroku日志从我所看到的内容中未显示任何帮助：

我已将此代码添加到服务器：

@socker.on('connect')
def handle_connect():
    print('THE HANDLE CONNECT FUNCTION WAS WRITTEN')
    try:
        socker.emit('testing', {'hello': 'hi'})
    except Exception as e:
        print(e)

，它不会被记录到heroku日志中，而其他日志则可以。 javascript socket.on（'connect'）函数以某种方式运行，但服务器端函数未运行

Flask-Socketio需要很长时间才能在Heroku上进行连接
