NetworkExtension connectOnDemand规则不工作

Question

我有一个新的NetworkExtension框架创建的VPN配置应用程序。它工作得很好，但是现在我需要添加一些规则来打开这个VPN，只有当我试图连接到一个特定的URL时。我计划使用NEVPNManager的connectOnDemand功能，但它似乎不适合我。当我在safari中打开http://some-site.com时，我的虚拟专用网连接应该建立起来，但出于某种原因它没有建立起来。我尝试了一种不同类型的配置，并使用生成的.mobileconfig文件使connectOnDemand工作，但没有成功。这有什么问题吗？我正在测试这样的代码：

let manager = NEVPNManager.sharedManager()

manager.enabled = true

manager.loadFromPreferencesWithCompletionHandler { (err) -> Void in
    manager.removeFromPreferencesWithCompletionHandler { (err0) -> Void in
                print("err0 \(err0)")
                print("err \(err)")
                let config = NEVPNProtocolIPSec()
                config.localIdentifier = "NEVPNProtocolIPSec"
                config.remoteIdentifier = "NEVPNProtocolIPSecRemote"
                config.disconnectOnSleep = true
                config.serverAddress = server
                config.authenticationMethod = .Certificate
                //configurating here
                manager.protocolConfiguration = config
                let onDemandRule1 = NEOnDemandRuleConnect()
                onDemandRule1.DNSSearchDomainMatch = ["some-site.com", "*.some-site.com"]

                manager.onDemandRules = [onDemandRule1]
                manager.onDemandEnabled = true
                manager.saveToPreferencesWithCompletionHandler({ (err2) -> Void in
                    print("err2 \(err2)")
                })
            }
        }

Answer 1

我把它和接下来的规则结合起来：

let onDemandRule = NEOnDemandRuleEvaluateConnection()
let evaluateRule = NEEvaluateConnectionRule(matchDomains: ["*.some-site.com"], andAction: .ConnectIfNeeded)
evaluateRule.probeURL = NSURL(string: "https://a.url.accecable.only.from.vpn")

onDemandRule.connectionRules = [evaluateRule]
manager.protocolConfiguration = config
manager.onDemandRules = [onDemandRule]

Answer 2

您需要添加行

manager.onDemandEnabled = true
