.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
