我在我的解决方案中创建了一个新项目。该项目是 ASP.NET Core 应用程序。

问题是当我点击 IISExpress 开始调试我有这个错误:

这些是项目属性Debug

我不知道该怎么办...有人可以帮助我吗？

编辑这是我的 launchSettings.json

{
  "iisSettings": {
    "windowsAuthentication": true,
    "anonymousAuthentication": true,
    "iis": {
       "applicationUrl": "http://localhost:8083/backendCore",
       "sslPort": 0
     },
    "iisExpress": {
       "applicationUrl": "http://localhost:8083",
       "sslPort": 0
     }
 },
 "$schema": "http://json.schemastore.org/launchsettings.json",
 "profiles": {
     "IIS Express": {
       "commandName": "IISExpress",
       "launchBrowser": true,
       "launchUrl": "backend",
       "environmentVariables": {
          "ASPNETCORE_ENVIRONMENT": "Development"
       }
     },
     "backendCore": {
        "commandName": "Project",
        "launchBrowser": true,
        "launchUrl": "weatherforecast",
        "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
        },
        "applicationUrl": "https://localhost:5001;http://localhost:5000"
       },
       "prova": {
          "commandName": "IIS",
          "launchBrowser": true,
          "launchUrl": "backend"
        }
       }
     }

和startup.cs

namespace backendCore
{
  public class Startup
  {
     public Startup(IConfiguration configuration)
     {
       Configuration = configuration;
     }

     public IConfiguration Configuration { get; }

     // This method gets called by the runtime. Use this method to add services to the container.
     public void ConfigureServices(IServiceCollection services)
     {
        services.AddControllers();
     }

     // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
     public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
     {
        if (env.IsDevelopment())
        {
           app.UsePathBase("/backend"); //Add this line
           app.UseDeveloperExceptionPage();
        }
        app.UseHttpsRedirection();

        app.UseRouting();

        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
           endpoints.MapControllers();
        });
     }
  }
}

这是我的 Controller 的片段(但后端永远不会在这里停止)

namespace backendCore.Controllers
{
public class AuthController : ControllerBase
{
    [Route("api/Auth/{language}/guest")]
    [HttpPost]
    
    public ActionResult guestAuth(string language)
    {
       return Ok(true);
    }

}

Answer 1

在startup.cs 文件Configure 方法中更改以下代码

if (env.IsDevelopment())
{
    app.UsePathBase("/backend"); //Add this line
    app.UseDeveloperExceptionPage();
}

这添加了一个中间件，它从请求路径中提取指定的路径库并将其后置到请求路径库中。这只针对开发环境，如果你的生产环境也配置了backend子文件夹，把它放在if条件之外。
