我正在關注this教程。在客戶端,在一個簡單的html頁面中,來自SignalR的客戶端集線器代理未定義;我錯過了什麼?SignalR客戶端集線器代理未定義
此鏈接正常工作(客戶端是在同一個解決方案的另一個asp.net mvc的項目):
http://localhost:28538/Scripts/jquery.signalR-2.0.0.min.js
http://localhost:28538/Scripts/jquery-1.8.2.min.js
http://127.0.0.1:9077/signalr/hubs
http://127.0.0.1:9077/signalr/js
我的HUB類:
class AlohaHub : Hub
{
public void Send(string name, string message)
{
Clients.All.addMessage(name, message);
}
}
啓動類(這將傳遞給WebApp.Start
):
class Startup
{
public void Configuration(IAppBuilder app)
{
app.MapSignalR();
}
}
該應用程序的主要部分(一個Windows服務,但這是不可能的levant):
class MyAppSvc : WinSvc.ISvc
{
IDisposable _app;
string _url = "http://127.0.0.1:9077";
public void OnShutdown()
{
_app.Dispose();
}
public void OnStart(string[] args)
{
_app = Microsoft.Owin.Hosting.WebApp.Start<MyApp.SigR.Startup>(_url);
}
public void OnStop()
{
_app.Dispose();
}
}
實際的html頁面;客戶端:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

var chat = $.connection.alohaHub;
alert(chat);
// Create a function that the hub can call to broadcast messages.
chat.client.addMessage = 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>

我猜這是由於跨域問題...你在同一個本地端口上託管SignalR嗎? –
否;端口是不同的。所以我添加了 customHeaders> httpProtocol>'to web.config;但沒有成功(或者我不瞭解這個話題)。 –
