信号器无法在2012R2服务器上的IIS8中托管的WCF服务中工作 [英] Signalr not working in WCF service hosted in IIS8 on 2012R2 server
问题描述
我是asp.net的新手，并且在过去的3天里尝试在我的C＃WCF服务中配置一个简单版本的signalR。但我好像在四处走动。第一个问题是关于需要加载/创建不同元素或signalR的位置的混淆。也许最好让我理解所需的设置。
我的设置如下：
我的服务应用程序是一个在Windows 2012R2服务器上的IIS8中运行的C＃WCF服务。 （服务）
我的客户端应用程序是在同一个Windows 2012R2服务器上运行的C＃WebForm应用程序（客户端）
客户端应用程序有一个名为myJavaScript.js的JavaScript文件（ JavaScript文件）
用户通过运行CLIENT访问服务在网络浏览器上，通常是Chrome（浏览器）
以下是我对 The服务，客户&在我试图通过signalR从服务向浏览器发送简单消息时， JavaScript文件。
更改为服务（应用程序名称DCRules2）
•从nuget Microsoft.AspNet下载。 SignalR v2.2.2
•从nuget下载Microsoft.AspNet.SignalR，Core v2.2.2
•从nuget下载Microsoft.AspNet.SignalRJS v2.2.2
•从nuget下载Microsoft.AspNet.SignalR.SystemWeb v2.2.2
•从nuget下载Microsoft.Owin.SystemWeb v3.1.0
•从nuget下载Microsoft.Owin v3.1.0
•从nuget下载Microsoft.Owin.Security v3.1.0
•从nuget Owin v1.0.0下载
添加了一个Owin启动类Startup1.cs
I am relatively new to asp.net and have spent the past 3 days trying to get a simple version of signalR configured in my C# WCF service. But I seem to be going around in circles. The first problem is confusion about where the different elements or signalR need to be loaded/created. Maybe it is best for me to give my understanding of the required setup.
My setup is as follows:
My Service application is a C# WCF service which runs in IIS8 on a windows 2012R2 server. ("The Service")
My Client application is a C# WebForm application running on the same windows 2012R2 server ("The Client")
The Client application has a JavaScript file called myJavaScript.js ("The JavaScript File")
Users access the service via the "CLIENT" running on a web browser, usually Chrome ("The Browser")
Below are the changes that I have made to "The Service", "The Client" & "The JavaScript file" in my attempts to send a simple message from the Service to the Browser via signalR.
Changes to "The Service" (application name DCRules2)
• Downloaded from nuget Microsoft.AspNet.SignalR v2.2.2
• Downloaded from nuget Microsoft.AspNet.SignalR,Core v2.2.2
• Downloaded from nuget Microsoft.AspNet.SignalRJS v2.2.2
• Downloaded from nuget Microsoft.AspNet.SignalR.SystemWeb v2.2.2
• Downloaded from nuget Microsoft.Owin.SystemWeb v3.1.0
• Downloaded from nuget Microsoft.Owin v3.1.0
• Downloaded from nuget Microsoft.Owin.Security v3.1.0
• Downloaded from nuget Owin v1.0.0
Added an Owin Startup Class Startup1.cs
using System;
using System.Threading.Tasks;
using Microsoft.AspNet.SignalR;
using Microsoft.Owin;
using Owin;
using DCRules2;
[assembly: OwinStartup(typeof(DCRules2.Startup1))]
namespace DCRules2
{
public class Startup1
{
public void Configuration(IAppBuilder app)
{
// For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=316888
//app.MapSignalR();
//app.MapSignalR("/~/signalr", new HubConfiguration());
var hubConfiguration = new HubConfiguration();
app.MapSignalR("/signalr", hubConfiguration);
}
}
}
添加了Hub类TiosHub.cs
Added Hub class TiosHub.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.AspNet.SignalR;
using Microsoft.AspNet.SignalR.Hubs;
namespace DCRules2
{
//[HubName("tios")]
public class TiosHub : Hub
{
// Tell all of the clients that there is an announcement
public void Announce(string message)
{
Clients.All.Announce(message);
}
}
}
重建服务并重新启动IIS
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++
更改为客户端（应用程序名称DCRulesWeb01）
•从nuget下载Microsoft.AspNet.SignalR.Client v2.2.2
•从nuget下载Microsoft.Owin.SystemWeb v3.1.0
•从nuget下载Microsoft.Owin v3.1.0
•从nuget Owin v1.0.0下载
我添加了对Webform1.aspx的javascript引用
Rebuilt the service and restarted IIS
++++++++++++++++++++++++++++++++++++++++++++++++
Changes to "The Client" (application name DCRulesWeb01)
• Downloaded from nuget Microsoft.AspNet.SignalR.Client v2.2.2
• Downloaded from nuget Microsoft.Owin.SystemWeb v3.1.0
• Downloaded from nuget Microsoft.Owin v3.1.0
• Downloaded from nuget Owin v1.0.0
I added the javascript references to Webform1.aspx
<script src="~/Scripts/jquery.signalR-2.2.2.js">
</script> <script src="~/signalr/hubs"></script>
我添加了一个announce（）方法Webform1.aspx.cs测试signalR
I added an announce() method to Webform1.aspx.cs to test signalR
// Test SignalR
public void Announce(string message)
{
string msg = message;
}
++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++名称DCRulesWeb01）
文件myJavaScript.js是一个客户端javascript文件，我将以下代码插入：
++++++++++++++++++++++++++++++++++++++++++++++++
Changes to "The JavaScript file" (application name DCRulesWeb01)
File myJavaScript.js is a clientside javascript file which I inserted the following code into:
// SignalR configuration
$(function () {
var tioshub = $.connection.tiosHub;
$.connection.hub.start().done(function () { });
tioshub.client.announce = function (message) {
console.info('Received message: ' +message);
}
});
最后我重新构建了客户端应用程序并发布了项目并重新启动了IIS
当我运行服务并按F12时，我收到以下错误
1.无法加载资源 - 服务器响应状态为404（未找到）jquery.signalR-2.2 .2.js
2.无法加载资源 - 服务器响应了状态404（未找到）集线器
3.未捕获TypeError：无法读取属性'tiosHub'未定义
有一件事我期望看到是没有发生的文件夹信号器/集线器的创建。我假设这与上面的404错误有关。
有谁可以解释我可能做错了什么？
什么我试过了：
我花了几天研究这个，掉了很多兔子洞，但仍然没有答案
finally I re-built the Client application and published the Project and re-started IIS
When I run the service and press F12 , I get the following errors
1. Failed to Load resource - the server responded with a status of 404 (not found) jquery.signalR-2.2.2.js
2. Failed to Load resource - the server responded with a status of 404 (not found) hubs
3. Uncaught TypeError: Cannot read property 'tiosHub' of undefined
One thing I expected to see was the creation of a folder signalr/hubs which has not happened. I am assuming that this is related to 404 error above.
Can anyone explain what I might be doing wrong ?
What I have tried:
I have spent days researching this, gone down many rabbit holes but still do not have an answer
推荐答案
（function（）{
var tioshub =
(function () { var tioshub =
.connection.tiosHub;
.connection.tiosHub;
。 connection.hub.start（）。done（function（）{}）;
tioshub.client.announce = function（message）{
console.info（'收到的消息：'+消息）;
}
}）;
.connection.hub.start().done(function () { }); tioshub.client.announce = function (message) { console.info('Received message: ' +message); } });
最后我重新构建了客户端应用程序并发布了项目并重新启动了IIS
当我运行该服务并按F12时，我收到以下错误
1.无法加载资源 - 服务器响应状态为404（未找到）jquery.signalR-2.2.2.js
2.无法加载资源ce - 服务器响应状态为404（未找到）集线器
3.未捕获TypeError：无法读取属性'tiosHub'未定义
我希望看到的一件事是创建一个尚未发生的文件夹信号器/集线器。我假设这与上面的404错误有关。
