部署应用程序时SignalR出错 [英] SignalR Error when I deploy application

问题描述

嘿伙计们我有一个问题，我需要一些帮助。我有一个SignalR Web项目，我通过控制台应用程序进行通信。当我在本地运行我的SignalR Web应用程序时它工作正常没有任何问题，但是当我将它部署到IIS并尝试创建集线器代理时，我得到下面的错误，我一直在拉我的头发整天，我找不到解决方案。任何帮助都非常苛刻。





错误：

解析值时遇到意外的字符：<路径''，第3行，第1位。}





控制台应用程序：

< pre lang =c＃> var connection = new HubConnection（txtSignalRWebsite.Text）;
// 根据服务器上的集线器名称设置集线器代理
var myHub = connection.CreateHubProxy（ dbHub ）;

// 开始连接
connection.Start（）。 ContinueWith（task = >
{
if （task.IsFaulted）
{
Console.WriteLine（ 错误 + task.Exception.ToString（ ））;
}
else
{
myHub.Invoke（ DisplayHello）;
}
}）。Wait（）;

Hey guys I have a problem which I need a little help with. I have a SignalR web project which I communicate with through a console application. When I run my SignalR Web application locally it works fine without any issues but when I deploy it to IIS and try create the hub proxy I get the error below, I have been pulling my hair out all day and I can't find a solution. Any help is very much apreciated.


Error:
"Unexpected character encountered while parsing value: <. Path '', line 3, position 1."}


Console application:

var connection = new HubConnection(txtSignalRWebsite.Text);
//Make proxy to hub based on hub name on server
var myHub = connection.CreateHubProxy("dbHub");

//Start connection
connection.Start().ContinueWith(task =>
{
    if (task.IsFaulted)
    {
        Console.WriteLine("Error" + task.Exception.ToString());
    }
    else
    {
        myHub.Invoke("DisplayHello");
    }
}).Wait();
