.NET Core项目指定运行端口

2021-08-19

Program.cs 中 

public static IHostBuilder CreateHostBuilder(string[] args) =>

            Host.CreateDefaultBuilder(args)

                .ConfigureWebHostDefaults(webBuilder =>

                {

                    webBuilder.UseKestrel()

                    .UseUrls(WebHelper.launch_url)

                    .UseStartup<Startup>();

                });

红色的部分指定运行网址，我这里 WebHelper.launch_url 在配置文件里定义的是 

"launch_url":"http://*:5200"，即端口是5200.

for  asp.net 7

var builder = WebApplication.CreateBuilder(args);

string url = WebHelper.get_item("launch_url");

builder.WebHost.UseUrls(url);

// Add services to the container.

builder.Services.AddControllersWithViews();

var app = builder.Build();
