使用Kestrel时可配置的端口号？

Question

我已完成以下操作，但仍然无效。正在运行dotnet myapp.dll仍会显示正在监听http://localhost:5000。

1. 创建 hosting.json

代码：

{
  "server.url": "http://*:5001"
}

1. 更新了 Program.cs

代码：

public class Program
{
    public static void Main(string[] args)
    {
        var config = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("hosting.json", optional: true, reloadOnChange: true)
            .Build();

        var host = new WebHostBuilder()
            .UseConfiguration(config) // added
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            //.UseUrls("http://*:5001")
            .UseIISIntegration()
            .UseStartup<Startup>()
            .Build();

        host.Run();
    }
}

1. 更新了 project.json

代码：

  "publishOptions": {
    "include": [
      "wwwroot",
      "Views",
      "Areas/**/Views",
      "appsettings.json",
      "web.config",
      "NLog.config",
      "hosting.json"
    ]

Answer 1

1. 您需要更改顺序：在文件读取之前应调用.SetBasePath

   var config = new ConfigurationBuilder()
       .SetBasePath(Directory.GetCurrentDirectory())
       .AddJsonFile("hosting.json", optional: true, reloadOnChange: true)
       .Build();
   

2. 使用server.urls，而不是server.url
