无法在launchSettings.JSON中设置Net.Core应用程序的端口 [英] Can't set the port for Net.Core application in launchSettings.JSON

问题描述

我已经编辑了 launchSettings.JSON 文件，并更改了端口.

I've edited launchSettings.JSON file and changed the port like so.

"Gdb.Blopp": {
  "commandName": "Project",
  "launchBrowser": false,
  "launchUrl": "http://localhost:4000",
  "environmentVariables": {
    "ASPNETCORE_ENVIRONMENT": "Development"
  }

尽管如此，它仍然从端口5000开始.是完全忽略了该设置还是我错过了其他东西?

It still starts on port 5000, though. Is that setting disregarded all toghether or am I missing something else?

推荐答案

当您按下F5/Ctr + F5并提供下拉菜单中的选项时，IDE(即Visual Studio)应该使用的launchSettings.json开始按钮旁边的菜单.

The launchSettings.json supposed to be used by IDEs (i.e. Visual Studio), when you hit F5/Ctr+F5 and offers the options from the pull-down menu next to the start button.

此外，您不应该直接编辑launcherSettings.json文件，而应使用项目属性"来更改内容.

Also you shouldn't directly edit that the launcherSettings.json file and instead use the Project Properties to change stuff.

这样做的原因之一是，如果您通过项目属性对其进行更改，Visual Studio还将编辑IIS Express文件(位于解决方案的.vs/config/applicationhost.config文件夹中).

One reason for this is that if you change it via project properties, Visual Studio will also edit the IIS Express files (located in the .vs/config/applicationhost.config folder of your solution).

如果要更改红est使用的端口，请使用Program.cs中的.UseUrls("http://0.0.0.0:4000")(从appsettings.json或hosting.json获取).

If you want to change the port kestrel uses, use .UseUrls("http://0.0.0.0:4000") (get it either from appsettings.json or hosting.json) in Program.cs.

如果您不想使用硬编码，也可以执行类似的操作

If you don't want to use hardcoded, you can also do something like this

创建hosting.json:

{
  "server": "Microsoft.AspNetCore.Server.Kestrel",
  "server.urls": "http://localhost:4000"
}

Program.cs

Program.cs

public class Program
{
    public static void Main(string[] args)
    {
        var config = new ConfigurationBuilder()
            .AddJsonFile("hosting.json", optional: false)
            .AddEnvironmentVariables(prefix: "ASPNETCORE_")
            .Build();

        var host = new WebHostBuilder()
            .UseConfiguration(config)
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseStartup<Startup>()
            .Build();

        host.Run();
    }
}

您也可以通过命令行进行操作(在Microsoft.Extensions.Configuration.CommandLine"包中，AddCommandLine调用在这里很重要).

You can also do that via commandline (AddCommandLine call is important here, from Microsoft.Extensions.Configuration.CommandLine" package).

var config = new ConfigurationBuilder()
    .AddCommandLine(args)
    .Build();

var host = new WebHostBuilder()
    .UseConfiguration(config)
    .UseKestrel()
    .UseContentRoot(Directory.GetCurrentDirectory())
    .UseIISIntegration()
    .UseStartup<Startup>()
    .Build();

host.Run();

然后通过dotnet run server.urls=http://0.0.0.0:4000运行它.

当您运行IIS/IISExpress时，茶est端口将由UseIISIntegration()确定.

When you run IIS/IISExpress the kestrel port will be determined by UseIISIntegration().
