我的架构类似于下图。我想知道在我的服务(也是单独的应用程序 - SignalR server
)上调用windows service
(这是单独的IIS应用程序)上的集线器操作的热点。换句话说,我想通过services
将通知从WebClients
推送到SignalR server
。在服务中使用.NET SignalR clients
是唯一的方法吗?如果我想在[Authorize]
方法上使用Hub
属性,该怎么办?之后,我将不得不为我的服务创建单独的用户?

是的,您可以在Windows服务中使用.NET客户端库。它们的行为方式与任何其他SignalR客户端相同。
在asp.net/signalr上有很多关于SignalR的综合例子。
Authentication options for .NET clients
进行身份验证的一种方法是让一个单独的页面只设置身份验证cookie,然后从Response
中选择cookie,然后在执行调用时在运行的Windows服务实例中使用它使用Hub
装饰的[Authorize]
上的方法。
文档中的代码段:
static void Main(string[] args)
{
var connection = new HubConnection("http://www.contoso.com/");
Cookie returnedCookie;
Console.Write("Enter user name: ");
string username = Console.ReadLine();
Console.Write("Enter password: ");
string password = Console.ReadLine();
var authResult = AuthenticateUser(username, password, out returnedCookie);
if (authResult)
{
connection.CookieContainer = new CookieContainer();
connection.CookieContainer.Add(returnedCookie);
Console.WriteLine("Welcome " + username);
}
else
{
Console.WriteLine("Login failed");
}
}
private static bool AuthenticateUser(string user, string password, out Cookie authCookie)
{
var request = WebRequest.Create("https://www.contoso.com/RemoteLogin") as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.CookieContainer = new CookieContainer();
var authCredentials = "UserName=" + user + "&Password=" + password;
byte[] bytes = System.Text.Encoding.UTF8.GetBytes(authCredentials);
request.ContentLength = bytes.Length;
using (var requestStream = request.GetRequestStream())
{
requestStream.Write(bytes, 0, bytes.Length);
}
using (var response = request.GetResponse() as HttpWebResponse)
{
authCookie = response.Cookies[FormsAuthentication.FormsCookieName];
}
if (authCookie != null)
{
return true;
}
else
{
return false;
}
}
https://www.contoso.com/RemoteLogin的代码段(在上例中使用):
namespace SignalRWithConsoleChat
{
public partial class RemoteLogin : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string username = Request["UserName"];
string password = Request["Password"];
bool result = Membership.ValidateUser(username, password);
if (result)
{
FormsAuthentication.SetAuthCookie(username, false);
}
}
}
}
