Websocket 握手状态 200 异常

Question

这是我的客户：

from websocket import create_connection
ws = create_connection("wss://127.0.0.1:8080",
sslopt={"cert_reqs": ssl.CERT_NONE, "check_hostname": False, "ssl_version": ssl.PROTOCOL_TLSv1})
data = json.dumps({"api_command":"sensor_data","session_id":session_id})
ws.send(data)

这是我的服务器：

if __name__ == '__main__':
txaio.start_logging(level='debug')
# SSL server context: load server key and certificate
# We use this for both WS and Web!
contextFactory = ssl.DefaultOpenSSLContextFactory('keys/server.key',
'keys/server.crt')
factory = WebSocketServerFactory(u"wss://127.0.0.1:9000")
# by default, allowedOrigins is "*" and will work fine out of the
# box, but we can do better and be more-explicit about what we
# allow. We are serving the Web content on 8080, but our WebSocket
# listener is on 9000 so the Origin sent by the browser will be
# from port 8080...
factory.setProtocolOptions(
allowedOrigins=[
"https://127.0.0.1:8080",
"https://localhost:8080",
]
)
factory.protocol = MyServerProtocol
listenWS(factory, contextFactory)
webdir = File(".")
webdir.contentTypes['.crt'] = 'application/x-x509-ca-cert'
web = Site(webdir)
reactor.listenSSL(8080, web, contextFactory)
#reactor.listenTCP(8080, web)
reactor.run()

当我运行客户端时，客户端中会抛出以下错误

websocket._exceptions.WebSocketBadStatusException: Handshake status 200

在服务器上：

2017-08-23T16:08:58+0300 WebSocketServerFactory (TLS) starting on 9000
2017-08-23T16:08:58+0300 Starting factory <autobahn.twisted.websocket.WebSocketServerFactory object at 0x04AADAF0>
2017-08-23T16:08:58+0300 Site (TLS) starting on 8080
2017-08-23T16:08:58+0300 Starting factory <twisted.web.server.Site object at 0x04ACD770>
2017-08-23T16:09:32+0300 "127.0.0.1" - - [23/Aug/2017:13:09:32 +0000] "GET / HTTP/1.1" 200 2042 "-" "-"

我不明白问题是什么。我的服务器来自此示例 https://github.com/crossbario/autobahn-python/tree/master/examples/twisted/websocket/echo_tls。如果我使用类似于该示例中所示的客户端，它可以很好地连接。不过，我无法使用简单的网络套接字库进行连接。

异常在 websocket 客户端create_connection引发

Answer 1

而不是

ws = create_connection(
"wss://127.0.0.1:8080",
sslopt={"cert_reqs": ssl.CERT_NONE, 
"check_hostname": False, 
"ssl_version": ssl.PROTOCOL_TLSv1
}
)

用

ws = create_connection(
"ws://127.0.0.1:8080",
sslopt={"cert_reqs": ssl.CERT_NONE, 
"check_hostname": False, 
"ssl_version": ssl.PROTOCOL_TLSv1}
)

它应该是"ws"而不是"wss"。

您可以使用websocket-server，如果您需要更多帮助，请告诉我
