.net core 修改网站启动端口

一、写死在代码

第 1 种方式

修改 Program.cs

public static IWebHostBuilder CreateWebHostBuilder(string[] args)
{
    var host =
    WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .UseKestrel(o => {
            o.Listen(IPAddress.Loopback, 6000);
        })
        ;
    return host;
}

第 2 种方式

修改 Program.cs

public static IWebHostBuilder CreateWebHostBuilder(string[] args)
{
    var host =
    WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .UseUrls("http://localhost:5000;https://localhost:5001")
        ;
    return host;
}

配置json文件

1. 增加 host.json 文件，内容：

 {
 	"urls": "http://localhost:5004;https://localhost:5005"
 }

• 3

2. 修改 Programe.cs

public static IWebHostBuilder CreateWebHostBuilder(string[] args)
{
    var config = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("host.json", optional: true)
        .Build();

    var host = WebHost.CreateDefaultBuilder(args)
        .UseStartup<Startup>()
        .UseConfiguration(config)
        ;
            
    return host;
}

或

public static IWebHostBuilder CreateWebHostBuilder(string[] args)
{
	var configuration = new ConfigurationBuilder().SetBasePath(Environment.CurrentDirectory)
		.AddJsonFile("host.json")
		.Build();
	var url = configuration["url"];
	return WebHost.CreateDefaultBuilder(args)
		.UseUrls(configuration["url"])
		.UseStartup<Startup>();
 }
