'System.Web.Routing.SignalRRouteExtensions.MapHubs(System.Web.Routing.RouteCollection)' 已過時: 'Use IAppBuilder.MapSignalR in an Owin Startup class. See http://go.microsoft.com/fwlink/?LinkId=320578 for more details.'
1. 先把SignalR移除掉,然後陸續安裝以下幾個package
PM> Uninstall-Package Microsoft.AspNet.SignalR –RemoveDependencies
PM> Install-Package Microsoft.AspNet.SignalR
PM> Install-Package Microsoft.AspNet.SignalR -Version 2.0.1
PM> Install-Package Microsoft.Owin
但是我居然在Console底下一直建立失敗,只好用 介面來新增
接著可以看到已經加入了這些參考
Scripts中也有了2.0.3的版本
為了確認SignalR能正確載入,之前會在global.asax加入RouteTable.Routes.MapHubs();
現在改變寫法了,先新增一個SignalR的資料夾,然後在裡面新增一個ChatHub.cs的類別
using System; using System.Web; using Microsoft.AspNet.SignalR; namespace SignalRChat { public class ChatHub : Hub { public void Send(string name, string message) { // Call the broadcastMessage method to update clients. Clients.All.broadcastMessage(name, message); } } }
接著再新增一個Startup.cs的類別
using Microsoft.Owin; using Owin; [assembly: OwinStartup(typeof(SignalRChat.Startup))] namespace SignalRChat { public class Startup { public void Configuration(IAppBuilder app) { // Any connection or hub wire up and configuration should go here app.MapSignalR(); } } }
接著在HTML碼裡面Key入以下的程式碼
<!DOCTYPE html> <html> <head> <title>SignalR Simple Chat</title> <style type="text/css"> .container { background-color: #99CCFF; border: thick solid #808080; padding: 20px; margin: 20px; } </style> </head> <body> <div class="container"> <input type="text" id="message" /> <input type="button" id="sendmessage" value="Send" /> <input type="hidden" id="displayname" /> <ul id="discussion"> </ul> </div> <!--Script references. --> <!--Reference the jQuery library. --> <script src="Scripts/jquery-1.6.4.min.js" ></script> <!--Reference the SignalR library. --> <script src="Scripts/jquery.signalR-2.0.2.min.js"></script> <!--Reference the autogenerated SignalR hub script. --> <script src="/signalr/hubs"></script> <!--Add script to update the page and send messages.--> <script type="text/javascript"> $(function () { // Declare a proxy to reference the hub. var chat = $.connection.chatHub; // Create a function that the hub can call to broadcast messages. chat.client.broadcastMessage = function (name, message) { // Html encode display name and message. var encodedName = $('<div />').text(name).html(); var encodedMsg = $('<div />').text(message).html(); // Add the message to the page. $('#discussion').append('<li><strong>' + encodedName + '</strong>: ' + encodedMsg + '</li>'); }; // Get the user name and store it to prepend to messages. $('#displayname').val(prompt('Enter your name:', '')); // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.start().done(function () { $('#sendmessage').click(function () { // Call the Send method on the hub. chat.server.send($('#displayname').val(), $('#message').val()); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); }); }); </script> </body> </html>
bundles.Add(new ScriptBundle("~/bundles/signalr").Include( "~/Scripts/json2.js", "~/Scripts/jquery.signalR-{version}.js"));
@Scripts.Render("~/bundles/signalR")
