最近我将 Apple Watch 升级到 WatchOS 6.0.1，iPhone 升级到 iOS 13.1.2，Xcode 升级到 11.1。MacOS 仍然是 10.14.6。
我创建了一个独立的 Apple Watch 项目，在其中我使用 Starscream 测试 Watch 和 WebSocket 服务器之间的通信：https ://github.com/daltoniam/Starscream
它在模拟器上完美运行，但在真正的 Apple Watch上，当我尝试连接到服务器时出现以下错误：
2019-10-08 18:57:53.064887+0200 BackgroundWebSocketOnlyWatch WatchKit Extension[251:31011] [] nw_connection_get_connected_socket [C1] Client called nw_connection_get_connected_socket on unconnected nw_connection
2019-10-08 18:57:53.068928+0200 BackgroundWebSocketOnlyWatch WatchKit Extension[251:31011] TCP Conn 0x16d8d5f0 Failed : error 0:50 [50]
websocket is disconnected: Optional("The operation couldn’t be completed. Network is down")
我将向您展示我的应用程序的代码：
接口控制器.swift
import WatchKit
import Foundation
import Starscream
class InterfaceController: WKInterfaceController, WebSocketDelegate {
let socket = WebSocket(url: URL(string: "ws://echo.websocket.org/")!)
@IBOutlet var label: WKInterfaceLabel!
/**************************************************************************************************/
override func awake(withContext context: Any?) {
super.awake(withContext: context)
socket.delegate = self
}
override func willActivate() {
// This method is called when watch view controller is about to be visible to user
super.willActivate()
}
override func didDeactivate() {
// This method is called when watch view controller is no longer visible
super.didDeactivate()
}
/************************************************************************************************/
@IBAction func connectButtonPressed() {
socket.connect()
}
@IBAction func sendButtonPressed() {
socket.write(string: "Hi!")
}
@IBAction func disconnectButtonPressed() {
socket.disconnect()
}
/******************************************************************************************/
func websocketDidConnect(socket: WebSocketClient) {
print("websocket is connected")
label.setText("Connected")
}
func websocketDidDisconnect(socket: WebSocketClient, error: Error?) {
print("websocket is disconnected: \(error?.localizedDescription)")
label.setText("Disconnected")
}
func websocketDidReceiveMessage(socket: WebSocketClient, text: String) {
print("got some text: \(text)")
label.setText("Received: \(text)")
createVibration()
}
func websocketDidReceiveData(socket: WebSocketClient, data: Data) {
print("got some data: \(data.count)")
}
/******************************************************************************************/
// Creates vibration
func createVibration() {
WKInterfaceDevice.current().play(.notification)
print("Vibration created")
}
}
我尝试在 iOS 13.1.2 中使用Starscream，它在Simulator和 real iPhone 上都能完美运行。
这是WatchOS 6 的错误还是红蜘蛛需要升级？
提前致谢！:)

我已将 Apple Watch 更新为 WatchOS 6.1，将 iPhone 更新为 iOS 13.2，但 WebSocket 仍然无法在手表上运行...
虽然有一些新错误：
