Question

我正在尝试设置一个iOS客户端，以便将SignalR-ObjC与我们的Web服务一起使用。当我们使用长轮询方法时，一切似乎都有效，但它在我们的生产环境中存在问题。所以我被指示切换到使用Web套接字方法。基于我在网上看过的代码示例，我认为应该使用我所拥有的代码，但服务通过webSocket:didFailWithError:方法返回错误。这是错误：

Error Domain=org.lolrus.SocketRocket Code=2132 "received bad response code from server 403" UserInfo={NSLocalizedDescription=received bad response code from server 403}

这是我在AppDelegate文件中找到的用于设置连接的代码：

<!-- language:objective c -->
-(void)initializePushNotificationsConnection
{
    // Connect to the hub on the service
    SRHubConnection* localHubConnection = [SRHubConnection connectionWithURL:kSignalRServiceUrl];
    SRHubProxy* notifications = (SRHubProxy*)[localHubConnection createHubProxy:@"notificationHub"];
    [notifications on:@"notificationSent" perform:self selector:@selector(addMessage:)];

    localHubConnection.started =  ^{

        NSString* userGuid = [OURAppSettings sharedSettings].loginModel.theUser.userGuid;
        if (!userGuid)
            userGuid = @"";

        NSString* connId = self.hubConnection.connectionId;
        if (!connId)
            connId = @"";

        NSDictionary* connectionDict = @{@"UserGuid": userGuid, @"Model": connId};
        NSData* jsonData = [NSJSONSerialization dataWithJSONObject:connectionDict options:0 error:nil];
        NSURL* connectionRegistrationServiceUrl = [NSURL URLWithString:kSignalRConnectionRegistrationUrl];
        NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:connectionRegistrationServiceUrl];
        [request setHTTPMethod:@"POST"];
        [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
        [request setHTTPBody:jsonData];

        [NSURLConnection sendAsynchronousRequest:request
                                           queue:[NSOperationQueue mainQueue]
                               completionHandler:^(NSURLResponse* response, NSData* data, NSError* connectionError)
         {
             if (connectionError)
             {
                 NSLog(@"Error: %@", connectionError);
                 return;
             }
         }];

        return;
    };

    //Set the object to the local property to break the strong connection so the block can reference the object
    self.hubConnection = localHubConnection;
    SRWebSocketTransport *webSocket = [[SRWebSocketTransport alloc] init];
    [self.hubConnection start:webSocket];
}

我已经尝试过Github和SO的多个建议，但他们都没有解决这个问题。我怀疑Web服务的设置方式存在问题，但我不是IIS专家，也不能轻松访问设置。我现在基本上只是猜测解决方案，所以如果有人有任何想法或建议，我愿意听取他们的意见。
