我使用Autobahn JS to Crossbar.io实现登录（使用wampcra）时出现了这些错误：
2018-04-13T09:04:34-0300 [Router 6948] failing WebSocket opening handshake ('This server only speaks WebSocket subprotocols wamp.2.cbor.batched, wamp.2.cbor, wamp.2.msgpack.batched, wamp.2.msgpack, wamp.2.ubjson.batched, wamp.2.ubjson, wamp.2.json.batched, wamp.2.json')
和

我认为这是一个高速公路版本问题。
Version: Crossbar.io COMMUNITY 17.11.1
答案 0 :(得分：0)
我怀疑高速公路是如何更新的。
解决方案： 重新安装高速公路。
删除你的AutobahnJS：
npm un autobahn -S
安装最新的AutobahnJS：
npm i autobahn -S
$ npm i autobahn -S + autobahn@18.3.2 updated 1 package in 8.259s
并尝试再次连接到Crossbar。
