websocket + wamp : 서버 PHP 및 클라이언트 python, tcp 연결이 끊어짐

Question

python3.3 클라이언트에서 작업 중입니다. 래칫 - wamp PHP 서버에 연결하고 주제에 가입해야합니다. asyncio와 autobahn을 설치했습니다.

이 예제는 https://github.com/tavendo/AutobahnPython/blob/master/examples/asyncio/wamp/beginner/client.py을 따르지만 TCP 연결이 끊어지면 핸드 셰이크가 작동하지 않습니다.

서버입니다 확인 (이 함께 연결되어있는 다른 응용 프로그램). 어떠한 제안? Thx!

Answer 1

fryederich,

래칫은 WAMP v1 not v2를 지원합니다. 사용하려는 Autobahn 클라이언트는 WAMP v2 용입니다. 호환되는 클라이언트의 경우 Autobahn Python 0.8.5을 사용해야합니다.

WAMPv2 호환 PHP 라이브러리가 필요하면 Thruway (이 프로젝트의 개발자 중 한 명)을 살펴보십시오. 최신 버전의 Autobahn Python과 JS에서 작동합니다.

Answer 2

Daviddan에 따르면 문제는 Wamp의 다른 버전 (asyncio는 V2, Ratchet V1을 사용함)이었습니다. 나는 서버 (Wamp V1) 나 클라이언트의 파이썬 버전 (파이썬 3.3에서는 wamp V1 구현을 찾지 못했습니다)을 변경할 수 없습니다 : 간단한 웹 소켓 파이썬 모듈 ("websocket")을 사용하여 wamp V1 프로토콜을 구현했습니다 매우 간단합니다 (here the V1 specifications).
