Question

我正在尝试使用ios客户端连接到我的服务器中心。如果我使用javascript中提供的教程客户端，它可以工作。但是，为了连接到集线器，我必须使用的路径是什么。

这是客户端IOS本机代码

NSString *url = [NSString stringWithFormat:@"http://10.0.0.120:7363/ChatHub"];
SRHubConnection *hubConnection = [SRHubConnection connectionWithURL:url];

 Start the connection
[hubConnection start];

这是我的服务器代码。我在OnConnected（）中有一个永远不会被调用的断点。

public class ChatHub : Hub
{
 public override Task OnConnected() {
 return base.OnConnected();  
}
 }

服务器上的文件名为ChatHub，它不在任何文件夹中。我直接在项目文件下。当我尝试运行它时，这是我的输出

线程{name =（null），num = 1}： - [SRConnection negotiate：] [第145行] [CONNECTION]将协商

我认为这与我的urlpath有关。

我收到此错误

我能够通过更改客户端pod规范以使用DyKnow / SignalR-ObjC'feature-2.0.0.beta1'的分支来实现此功能，然后添加一些代码以将内容类型设置为application / json for all请求以路径中的“/ signalr”开头。

class Startup
{

    public void Configuration(IAppBuilder app)
    {       
        app.Use(async (env, next) => // owin middleware
            {
                //set headers
                env.Response.OnSendingHeaders( state =>
                {
                    PathString pathstring = new PathString("/signalr");
                    if (env.Request.Path.HasValue && env.Request.Path.StartsWithSegments(pathstring))
                    {
                        var resp = (OwinResponse)state;
                        resp.ContentType = "application/json";
                    }

                }, env.Response);

                await next();

            });

        app.RunSignalR();

    }
}
