如何解决使用JavaScript连接到Crossbar服务器会导致“到另一端的连接以一种不整洁的方式丢失”错误
我一直在尝试使用Autobahn（JavaScript）和Crossbar创建一个基于WAMP RPC的简单应用程序。该脚本在安全连接和不安全连接中均不起作用。
横杠config.json：-

}

}
}
}
}

}

}
JavaScript：-
var connection=null;
AUTOBAHN_DEBUG = true;
require.config({
baseUrl: ".",paths: {
"autobahn":
"https://[domain]/path/to/autobahn.min.js","when": "https://cdnjs.cloudflare.com/ajax/libs/when/2.7.1/when"
},shim: {
"autobahn": {
deps: ["when"]
}
}
});
require(["autobahn"],function(autobahn) {
console.log("Ok,Autobahn loaded",autobahn.version);
var connection = new autobahn.Connection({
transports: [{
type: 'websocket',port: '8080',host: '[domain]',url: "wss://[domain]:8080",}],realm: "name_1",max_retries: "0"
});
connection.onopen = function (session,details) {
// Publish,Subscribe,Call and Register
// session.register('com.myapp.add2',add2);
// session.call('com.myapp.add2',[2,3]).then(function showSum(res) {
// console.log('sum is',res);
// },session.log);
console.log("Connection opened.");
};
connection.onclose = function (reason,details) {
console.log("Connection closed.");
}
connection.open();
});
用于安全连接的横线跟踪：-
[Router 32589 crossbar.router.protocol.WampWebSocketServerProtocol] connection accepted from peer tcp4:[ip_address]:6589
[Router 32589 crossbar.router.protocol.WampWebSocketServerProtocol] Connection made to tcp4:[ip_address]:6589
[Router 32589 crossbar.router.protocol.WampWebSocketServerProtocol] Connection to/from tcp4:[ip_address]:6589 was lost in a non-clean fashion: Connection to the other side was lost in a non-clean fashion: Connection lost.
[Router 32589 crossbar.router.protocol.WampWebSocketServerProtocol] _connectionLost: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionLost'>: Connection to the other side was lost in a non-clean fashion: Connection lost.
用于安全连接的JavaScript控制台日志：-
autobahn.min.js:90 trying to create WAMP transport of type: websocket
autobahn.min.js:90 using WAMP transport type: websocket
autobahn.min.js:181 WebSocket connection to 'wss://[domain]:8080/' Failed: WebSocket opening handshake was canceled
autobahn.min.js:87 connection closed unreachable {reason: null,message: null,retry_delay: null,retry_count: null,will_retry: false}
main.js:43 Connection closed.
用于非安全连接的交叉代码和Javascript代码相同，除了端口为8081并将wss更改为ws。
不安全连接的横线跟踪：-
[Router 32589 crossbar.router.protocol.WampWebSocketServerProtocol] connection accepted from peer tcp4:[ip_address]:7110
[Router 32589 crossbar.router.protocol.WampWebSocketServerProtocol] Connection made to tcp4:[ip_address]:7110

[Router 32589 crossbar.router.protocol.WampWebSocketServerProtocol] Connection to/from tcp4:[ip_address]:7110 was aborted locally
[Router 32589 crossbar.router.protocol.WampWebSocketServerProtocol] _connectionLost: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionAborted'>: Connection was aborted locally using ITCPTransport.abortConnection.
不安全连接的JavaScript控制台日志：-
autobahn.min.js:90 using WAMP transport type: websocket
autobahn.min.js:181 WebSocket connection to 'ws://[domain]:8081/' Failed: Error in connection establishment: net::ERR_CONNECTION_RESET
autobahn.min.js:87 connection closed unreachable {reason: null,will_retry: false}
main.js:43 Connection closed.
最初，我在Crossbar配置中没有CA证书（错误没有更改）。我认为应该添加它们，因为它可能与此有关，因此我从https://letsencrypt.org/2015/06/04/isrg-ca-certs.html获得了它们（不确定这是否正确）。也从https://letsencrypt.org/certificates/开始尝试过，但是这让我头疼（我什至需要？）。
我不确定现在是哪种情况还是我遗漏了什么，是什么导致了这些问题。 docs充其量是脚。
请帮助？
