如果從靜止狀態連接超時，我如何刷新SignalR連接

Question

我有一個使用SignalR的角度應用程序。當用戶通過身份驗證時，我初始化到服務器的連接。我相信，如果客戶在一段時間後不活動，它將斷開連接。使用下面的代碼，如果它與不活動斷開，我將如何重新連接？

var initializeSockets = function(){ 
    self.proxy = null; 
    var connection = $.hubConnection(ENV.socketEndpoint,{ 
     qs: {token:User.getToken()}, 
     logging: false, 
     useDefaultPath: false 
    }); 
    self.proxy = connection.createHubProxy('messageCreatedEmitter'); 
    self.proxy.on('onMessageCreated',function(data){ 
    //the following is wrapped in a try catch 
    //because it will break in a browser, and 
    //will not allow the message to be emitted 
    try { 
     Alert.messageReceived(); 
    } catch (e) { 
    } 
    $rootScope.$emit('Messages:messageReceived',data); 
    }) 

    if($.connection.hub && $.connection.hub.state === $.signalR.connectionState.disconnected 
    || $.connection.hub.state === undefined){ 
    connection.start().done(function(){ 
     $log.info('connected'); 
    }) 
    } 
} 

$rootScope.$on('User:userAuthenticated',function(event,user){ 
    initializeSockets(); 
})

您可以注意斷開連接並重新連接;

$.connection.yourHubName.client.disconnect(function() { 
    $.connection.hub.start(); 
});
