Question

我正在测试actioncable和nativescript并得到上面的错误。我已经在我的github上设置了测试应用程序。

nativescript应用程序来自nativescript-actioncable包。这只发生在iOS上，Android连接正常。

我找不到关于这个问题的任何信息，这让我发疯了。任何帮助都会很棒。

以下是控制台输出：

Rails控制台：

我遇到了同样的错误，并通过将actioncable插件替换为nativescript-websockets并编写代码与我自己与actioncable服务器进行通信来解决此问题。

以下是我使用的示例代码

this.socket = new WebSocket('ws://192.168.8.104:3000/cable', []);
this.socket.on('open', function(evt) {
    console.log("Hey I'm open");
     var identifier = JSON.stringify({"channel": "ConversationsChannel"});
     var data = {"command": "subscribe", "identifier": identifier};
     var payload = JSON.stringify(data);
    evt.target.send(payload);
});
this.socket.on('message', function(socket, message) {console.log("Got a message", message);});
this.socket.on('close', function(socket, code, reason) { console.log("Socket was closed because: ", reason, " code: ", code); });
this.socket.on('error', function(socket, error) { console.log("Socket had an error", error);});

并发送消息

public sendMessage() {
        // "{"command":"message","identifier":"{\"channel\":\"ConversationsChannel\",\"conversation_id\":\"12\"}","data":"{\"message\":\"ssss\",\"conversation_id\":\"12\",\"user_id\":39,\"action\":\"send_message\"}"}"
         var data = JSON.stringify({"message": "ssss","conversation_id":"12","user_id":39,"action":"send_message"});
         var identifier = JSON.stringify({"channel": "ConversationsChannel"});
         var payload = JSON.stringify({"command": "message", "identifier": identifier, "data": data});
         this.socket.send(payload);
    }

同样，您可以编写发送有效负载的取消订阅

"{"command":"unsubscribe","identifier":"{\"channel\":\"ConversationsChannel\",\"conversation_id\":\"12\"}"}"

或者您可以转到node_modules / nativescript-actioncable / lib / action_cable.js并从此处更改第240行

this.webSocket = new WS(this.consumer.url, {protocols: protocols, headers: headers});

到这个

this.webSocket = new WS(this.consumer.url, {protocols: ["actioncable-v1-json"], headers: headers});

我希望这会给你一个想法，如果你需要更多的帮助，请告诉我。

错误1006表示客户端部分由于某些错误而终止，因此可能是与插件相关的问题。也许您可以验证插件是否正常工作（例如，使用其他服务this进行测试）？

使用ios运行nativescript-actioncable时获取错误代码：1006
