ASP.NET Core SignalR实时推送配置，业务层实时推送SignalR消息
web框架版本：.NET 6
不需要安装nuget有关signalr的包
微软参考文档：
https://docs.microsoft.com/zh-cn/aspnet/core/tutorials/signalr?view=aspnetcore-6.0&tabs=visual-studio
Startup.cs配置
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;
using System.Threading.Tasks;
namespace WebMvcNetCore.TuShi.FenGong
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
try
{
services.AddSignalR();
services.AddMvcCore();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
}
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.UseStaticFiles();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Main}/{id?}");
endpoints.MapHub<Models.ChatHub>("/chatHub");
});
}
}
}
web项目中配置集线器类
namespace WebMvcNetCore.TuShi.FenGong.Models
{
/// 添加SignalR的前端js文件
*.cshtml页面代码
<div class="table-fun" id="workHandMsg" style="color:#FF33FF;margin-right:300px;font-weight:bold;">
div>
<script src="~/lib/microsoft/signalr/dist/browser/signalr.min.js">script>
<script type="text/javascript">
//后台推送到页面消息
var connection = new signalR.HubConnectionBuilder().withUrl("/chatHub").build();
connection.start().then(function () {
console.log('signalR连接成功');
}).catch(function (err) {
return console.error(err.toString());
});
connection.on("ReceiveMessage", function (message) {
//console.log(message);
console.log('后台消息：'+message);
$("#workHandMsg").html(message);
});
script>
在业务层需要推送的地方代码参考，这里用了委托
WorkerController.cs
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using MvcSimplePager;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using WebMvcNetCore.TuShi.FenGong.IBusiness;
using WebMvcNetCore.TuShi.FenGong.Model;
using WebMvcNetCore.TuShi.FenGong.Models;
namespace WebMvcNetCore.TuShi.FenGong.Controllers
{
/// IWorkBusiness.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WebMvcNetCore.TuShi.FenGong.Model;
namespace WebMvcNetCore.TuShi.FenGong.IBusiness
{
/// IWorkBusiness.cs实现类：

using WebMvcNetCore.TuShi.FenGong.IBusiness;
using WebMvcNetCore.TuShi.FenGong.IDAL;
using WebMvcNetCore.TuShi.FenGong.Model;
