通过.Net Core 3.1中的Web浏览器公开控制台应用程序信息 [英] Expose console app info through web browser in .Net core 3.1

问题描述

我有一个沉重的控制台应用程序，该应用程序执行多个线程，这些线程可以读取，执行计算并写入不同情况下的输出.现在，我试图为所有人创建一种方法，使每个人都可以使用localhost或http/https通过网络浏览器访问数据(实时或接近实时).

I have a heavy console app that executes several threads that read, perform calculations and write to outputs in different scenarios. Now I'm triying to simply create a way for everyone to be able to access to the data (real-time or near-real-time) through a web browser using either localhost or http/https.

我也尝试过遵循此资源作为其他.我实际上已经四处查看并发现了有关自我托管的信息，但是我真的不知道如何以简单的方式实现它.

I've tried following this resource as well as this other. I've actually looked around and found about self hosting, but I don't really know how to implement it in a simple manner.

为简便起见，我添加了一个非常简单的控制台应用程序示例:

for brevity's sake, I add a very simple example of a console app:

using System;
using System.Collections.Concurrent;
using System.Threading;

namespace ConsoleApp1
{
    class Program
    {
        public static int x = 0;
        public static int y = 0;
        public static int z = 0;
        public static ConcurrentDictionary<String, int> ValuesDictionary = new ConcurrentDictionary<string, int>();

        static void Main(string[] args)
        {
            //Function that updates the values in the dictionary
            Thread createInputFileThread = new Thread(() => UpdateDictionaryThreadFunction(10000));
            createInputFileThread.Start();

            //How to start a simple web host here!
        }

        public static void UpdateDictionaryThreadFunction(int refreshTime)
        {
            while (true)
            {
                Thread.Sleep(refreshTime);
                if (x < 100000 && y < 100000 && z < 100000)
                {
                    ValuesDictionary.AddOrUpdate("ValueX", x, (key, oldValue) => oldValue + 1);
                    ValuesDictionary.AddOrUpdate("ValueY", y, (key, oldValue) => oldValue + 2);
                    ValuesDictionary.AddOrUpdate("ValueZ", z, (key, oldValue) => oldValue + 3);
                }
                else
                {
                    ValuesDictionary.AddOrUpdate("ValueX", x, (key, oldValue) => 0);
                    ValuesDictionary.AddOrUpdate("ValueY", y, (key, oldValue) => 0);
                    ValuesDictionary.AddOrUpdate("ValueZ", z, (key, oldValue) => 0);
                }
            }
        }
    }
}

这里的目标是通过 localhost:someport 或 http://somename:someport 之类的方法来访问ValuesDictionary中的数据，并获得诸如以下内容:值将每x秒刷新一次)

The goal here would be to access the data in the ValuesDictionary through something like localhost:someport or http://somename:someport and obtain something like: (The values would be refreshed every x seconds)

<身体>

名称	值
ValueX	34
ValueY	42
ValueZ	42

推荐答案

您使用.net core ..您想要一个在某些端口上提供TCP-IP的控制台应用程序.要将Kestrel链接到您的控制台应用程序，分配请求-接收器事件并在端口上启动它..要重复刷新客户端，您可以使用客户端本地JS和计时器.您的服务器可以为客户端的浏览器生成包含该JS部分的常规HTML.

You use .net core.. you want a console app that serves TCP-IP on some port.. a minimal solution I would say is to link Kestrel to your console app, assign the request-receiver event and launch it on your port.. to repeatedly refresh the client you can use client side local JS with a timer. Your server can generate the usual HTML incorporating that JS part for the client's browser.

在控制台应用程序中使用Kestrel的示例:

Example of using Kestrel in a Console app:

注意:这是老式的快速解决方案".同样，使用Kestrel，最好先构建应用程序作为报告服务，而不受平台选择的影响.然后，您可以插入"您将来可能需要使用的任何平台(SignalR，Blazor，ASP，Azure等)中的代码

NOTE: this is an old fashioned "quick solution". Also with Kestrel, it is better to structure your app first, as a reporting Service, independent of the platform choices. You could then "plugin" that code in any platform you may need to use in the future (SignalR, Blazor, ASP, Azure etc)
