ios - 域=NSPOSIXError域代码=61

Question

我正在尝试使用 SocketRocket 连接客户端(iOS 应用程序)和服务器(Node.js)，如下所示。

iOS(套接字火箭):

NSURL *url = [NSURL urlWithString:@"ws://localhost:8080"];
SRWebSocket *_socket = [SRWebSocket alloc] initWithURLRequest:[NSURLRequest requestWithURL:url];
_socket.delegate = self;
[_socket open];

/* SRWebSocketDelegate */
-(void)webSocketDidOpen:(SRWebSocket*)webSocket{
    [webSocket send:@"something"];
}
-(void)webSocket:(SRWebSocket*)webSocket didReceiveMessage:(id)message{
    NSLog(@"didReceiveMessage: %@",[message description]);
}
-(void)webSocket:(SRWebSocket*)webSocket didFailWithError:(NSError*)error{
    NSLog(@"the Error: %@",error);
}

Node.js(ws):

var WebSocketServer = require('ws').Server
var wss = new WebSocketServer({
    host:'localhost',
    port:8080
});
wss.on('connection',function(ws){
    ws.on('message',function(message){
        console.log('received: %s', message);
        ws.send(message);
    });
});

然后，我收到以下消息:

the error: Error Domain=NSPOSIXErrorDomain Code=61 "The operation couldn’t be completed. Connection refused"

我已经搜索过这个问题的解决方案，但找不到确切的解决方案。我该如何解决这个问题？？

正在连接到 iPhone 上的 Wi-Fi 网络。也许解决了那个问题。
