如何快速将互联网连接类型发送到服务器：Alamofire [关闭]

Question

如何将互联网连接类型分配给字符串变量。请有人帮助我。这是我的代码

reachabilityManager?.listener = { checkConection in
            switch checkConection {
            case .reachable(.ethernetOrWiFi):
                print("The network is reachable over the WiFi connection")
                break
            case .notReachable:
                print("internet is not reachable")
                break
            case .reachable(.wwan):
                print("internet is not working with status \(checkConection)")
                break
            case .unknown:
                print("internet status is unknown")
                break
            }
            print("Data",checkConection)
        }
    }
    reachabilityManager?.startListening()

我必须将该字符串参数发送到服务器。

似乎checkConnection 有一个自定义的 enum 类型的 Alamofire，NetworkReachabilityStatus (Alamofire source code)，它没有原始值，也不符合 CustomStringConvertible。

要从enum 中获取String 值，可以使其符合CustomStringConvertible，然后使用它的description 属性。只需确保对 ConnectionType 也执行此操作，这是另一个 enum，它是 NetworkReachabilityStatus.Reachable 的关联值。

extension ConnectionType: CustomStringConvertible {
    public var description: String {
        switch self {
        case .EthernetOrWiFi:
            return "Ethernet of WiFi"
        case .WWAN:
            return "WWAN"
        }
    }
}

extension NetworkReachabilityStatus: CustomStringConvertible {
    public var description: String {
        switch self {
        case .NotReachable:
            return "Not Reachable"
        case .Unknown:
            return "Unknown"
        case let .Reachable(connectionType):
            return "Reachable through \(connectionType.description)"
        }
    }
}

然后在你的代码中使用它：

var reachabilityStatusString: NetworkReachabilityStatus?

reachabilityManager?.listener = { checkConection in
    reachabilityStatusString = checkConnection.description
    print("Reachability status: \(reachabilityStatusString ?? "Unknown")")
}
reachabilityManager?.startListening()
