.Net Core实战教程（二）：设置Kestrel的IP与端口的几种方法

1.直接写在代码方式

Program.cs代码如下：

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Threading.Tasks;

using Microsoft.AspNetCore;

using Microsoft.AspNetCore.Hosting;

using Microsoft.Extensions.Configuration;

using Microsoft.Extensions.Logging;

namespace myapi

{

    public class Program

    {

        public static void Main(string[] args)

        {

            CreateWebHostBuilder(args).Build().Run();

        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>

            WebHost.CreateDefaultBuilder(args)

                .UseUrls("http://192.168.3.162:6600")

                .UseStartup<Startup>();

    }

}

命令行cmd进入发布目录输入命令：

dotnet myapi.dll

2.命令行运行时动态输入IP与端口方式

Program.cs代码如下：

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Threading.Tasks;

using Microsoft.AspNetCore;

using Microsoft.AspNetCore.Hosting;

using Microsoft.Extensions.Configuration;

using Microsoft.Extensions.Logging;

namespace myapi

{

    public class Program

    {

        public static void Main(string[] args)

        {

            CreateWebHostBuilder(args).Build().Run();

        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>

            WebHost.CreateDefaultBuilder(args)

                .UseConfiguration(new ConfigurationBuilder().AddCommandLine(args).Build())

                .UseStartup<Startup>();

    }

}

命令行cmd进入发布目录输入命令：

dotnet myapi.dll --server.urls "http://192.168.3.185:7100"

3.通过配置文件方式

Program.cs代码如下：

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Threading.Tasks;

using Microsoft.AspNetCore;

using Microsoft.AspNetCore.Hosting;

using Microsoft.Extensions.Configuration;

using Microsoft.Extensions.Logging;

namespace myapi

{

    public class Program

    {

        public static void Main(string[] args)

        {

            CreateWebHostBuilder(args).Build().Run();

        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>

            WebHost.CreateDefaultBuilder(args)

                .UseConfiguration(new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("hosting.json", optional: true).Build())

                .UseStartup<Startup>();

    }

}

项目添加"hosting.json "文件，代码如下：

{

  "server.urls": "http://192.168.3.185:8800"

}

命令行cmd进入发布目录输入命令：

dotnet myapi.dll
