我试图在本地主机上运行websocket服务器并使用ngrok将其转发到web。但无法弄清楚如何。这些是来自AutobahnPython git repository https://github.com/tavendo/AutobahnPython的原始代码。
服务器代码:
from autobahn.twisted.websocket import WebSocketServerProtocol, \
WebSocketServerFactory
class MyServerProtocol(WebSocketServerProtocol):
def onConnect(self, request):
print("Client connecting: {0}".format(request.peer))
def onOpen(self):
print("WebSocket connection open.")
def onMessage(self, payload, isBinary):
if isBinary:
print("Binary message received: {0} bytes".format(len(payload)))
else:
print("Text message received: {0}".format(payload.decode('utf8')))
## echo back message verbatim
self.sendMessage(payload, isBinary)
def onClose(self, wasClean, code, reason):
print("WebSocket connection closed: {0}".format(reason))
if __name__ == '__main__':
import sys
from twisted.python import log
from twisted.internet import reactor
log.startLogging(sys.stdout)
factory = WebSocketServerFactory("ws://localhost:9000", debug = False)
factory.protocol = MyServerProtocol
reactor.listenTCP(9000, factory)
reactor.run()
客户代码:
from autobahn.twisted.websocket import WebSocketClientProtocol, \
WebSocketClientFactory
class MyClientProtocol(WebSocketClientProtocol):
def onConnect(self, response):
print("Server connected: {0}".format(response.peer))
def onOpen(self):
print("WebSocket connection open.")
def hello():
self.sendMessage(u"Hello, world!".encode('utf8'))
self.sendMessage(b"\x00\x01\x03\x04", isBinary = True)
self.factory.reactor.callLater(1, hello)
## start sending messages every second ..
hello()
def onMessage(self, payload, isBinary):
if isBinary:
print("Binary message received: {0} bytes".format(len(payload)))
else:
print("Text message received: {0}".format(payload.decode('utf8')))
def onClose(self, wasClean, code, reason):
print("WebSocket connection closed: {0}".format(reason))
if __name__ == '__main__':
import sys
from twisted.python import log
from twisted.internet import reactor
log.startLogging(sys.stdout)
factory = WebSocketClientFactory("ws://localhost:9000", debug = False)
factory.protocol = MyClientProtocol
reactor.connectTCP("127.0.0.1", 9000, factory)
reactor.run()
这是更改后的代码:
from autobahn.twisted.websocket import WebSocketClientProtocol, \
WebSocketClientFactory
class MyClientProtocol(WebSocketClientProtocol):
def onConnect(self, response):
print("Server connected: {0}".format(response.peer))
def onOpen(self):
print("WebSocket connection open.")
def hello():
self.sendMessage(u"Hello, world!".encode('utf8'))
self.sendMessage(b"\x00\x01\x03\x04", isBinary = True)
self.factory.reactor.callLater(1, hello)
## start sending messages every second ..
hello()
def onMessage(self, payload, isBinary):
if isBinary:
print("Binary message received: {0} bytes".format(len(payload)))
else:
print("Text message received: {0}".format(payload.decode('utf8')))
def onClose(self, wasClean, code, reason):
print("WebSocket connection closed: {0}".format(reason))
if __name__ == '__main__':
import sys
from twisted.python import log
from twisted.internet import reactor
log.startLogging(sys.stdout)
#~ factory = WebSocketClientFactory("ws://localhost:9000", debug = False)
factory = WebSocketClientFactory("ws://ngrok.com:xxxxx", debug = False)
factory.protocol = MyClientProtocol
reactor.connectTCP("ws://ngrok.com", xxxxx, factory)
reactor.run()
这是ngrok命令: ./ ngrok -proto = tcp 9000
我在这里做错了什么?
答案 0 :(得分:6)
我尝试使用
ngrok http 8091
(其中8091是使用Racthet IO运行我的WebsocketServer的端口)并且它可以工作。我仍然可以连接到Websocket,用连接上的http
替换ws
。
