我已经编写了一些API使用websocketapp与网站进行通信。它只能在2 pc上正常工作。如果我将代码放到其他PC上，则websocket不会收到任何消息并关闭。我尝试了很多不同的机器和操作系统，许多版本的python（包括相同的版本），无线和有线连接，但没有任何变化。没有错误或异常。会是什么？
编辑：我不拥有网站或服务器。所有其他方法都发送消息并在on_socket_message中解析响应

这里是在Gevent Websockets下运行的示例。这使其成为ASYNC（我怀疑这是您的问题的一部分），并允许双向通信。
import gevent
from gevent import monkey, signal, Timeout, sleep, spawn as gspawn
monkey.patch_all()
from gevent.pywsgi import WSGIServer
from geventwebsocket.handler import WebSocketHandler
from geventwebsocket import WebSocketError
import bottle
from bottle import get, route, template, request, response, abort, static_file
import ujson as json
@route('/static/<filepath:path>')
def server_static(filepath):
return static_file(filepath, root='static')
@route('/ws/remote')
def handle_websocket():
wsock = request.environ.get('wsgi.websocket')
if not wsock:
abort(400, 'Expected WebSocket request.')
while 1:
try:
message = ''
with Timeout(2, False) as timeout:
message = wsock.receive()
if message:
message = json.loads(message)
if 'command' in message:
r.command(message['command'])
except WebSocketError:
break
except Exception as exc:
print(str(exc))
@get('/')
def remote():
return template('templates/remote.tpl', title='WebsocketTest', websocket=WEBSOCKET, command='command', status=status)
if __name__ == '__main__':
r=None
status="Connecting..."
gspawn(initialize)
print 'Started...'
HOST = socket.gethostbyname(socket.gethostname())
HOST = 'localhost'
WEBSOCKET = 'ws://{}/ws/remote'.format(HOST)
botapp = bottle.app()
server = WSGIServer(("0.0.0.0", 80), botapp, handler_class=WebSocketHandler)
def shutdown():
print('Shutting down ...')
server.stop(timeout=60)
exit(signal.SIGTERM)
gevent.signal(signal.SIGTERM, shutdown)
gevent.signal(signal.SIGINT, shutdown) #CTRL C
server.serve_forever()
然后在您的HTML中，您确实应该使用重新连接websocket库 https://github.com/joewalnes/reconnecting-websocket
<button id="TRIGGERED" type="button" class="btn btn-outline-primary">TRIGGER</button>
<script type="text/javascript" src="/static/reconnecting-websocket.min.js"></script>
<script>
var ws = new ReconnectingWebSocket('{{websocket}}');
ws.reconnectInterval = 3000;
ws.maxReconnectAttempts = 10;
ws.onmessage = function (evt) {
var wsmsg = JSON.parse(evt.data);
console.log(evt.data)
};
$("button").click(function() {
<!--console.log(this.id);-->
ws.send(JSON.stringify({'{{command}}': this.id}));
});
</script>
