在 Swift 上使用 Socket.io“从服务器收到未知错误...”

Question

我正在尝试连接到 Xcode 服务器的内部 socket.io。我使用以下方法初始化客户端：

self.socket = SocketIOClient(socketURL: NSURL(string: "https://37.203.216.82")!, options: [.Path("/xcode/internal/socket.io"), .Log(true), .Reconnects(true), .ForceNew(true), .SessionDelegate(self), .SelfSigned(true)])

但是当我使用时self.socket.connect()我得到这样的响应：

2016-07-15 16:13:49.179 MyApp[84260:1941316] LOG SocketIOClient: Adding handler for event: connect
2016-07-15 16:13:49.180 MyApp[84260:1941316] LOG SocketIOClient: Adding handler for event: integrationStatus

2016-07-15 16:13:49.324 MyApp[84260:1941786] ERROR SocketIOClient: Got unknown error from server Welcome to socket.io.

"Got unknown error from server Welcome to socket.io."
)

socket.io.js我尝试更改文件的路径，xcode/internal/socket.io/1/但它都给出相同的响应，而是Welcome to socket.io被那里的文件内容替换。

Socket.IO-Client-Swift (16.0.1)：版本，需要添加：.forceWebsockets(true)。

例子：

let manager = SocketManager(socketURL: URL(string: "http://localhost:8080")!, config: [.compress, .forceWebsockets(true)])
let socket = manager.defaultSocket

尝试将其ws作为协议，如下所示：

... NSURL(string: "ws://37.203.216.82") ...
