launchSettings.json launchUrl 不起作用“api/values”

Question

我正在尝试更改http://localhost:5001/api/values 路由，但程序卡在此网址。

我阅读了这个解决方案

How to change the default controller and action in ASP.NET Core API?

How to redirect root to swagger in Asp.Net Core 2.x?

https://medium.com/quick-code/routing-in-asp-net-core-c433bff3f1a4

每个人都写同样的东西，但不适合我。

我的launchSetting.json 文件是

{  "$schema": "http://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:54650",
      "sslPort": 44382
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "ShoppingBasketAPI": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "https://localhost:5001;http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

我试图改变app.UseMvc();

https://docs.microsoft.com/en-us/aspnet/core/fundamentals/routing?view=aspnetcore-2.2

这也不行。api/values 来自哪里？我想不通。

我的控制器属性路由是 [Route("api/[controller]/[action]")]

Answer 1

我正在使用 VSCode，并且在我身上发生了同样的情况，但在 Windows 上。 我只是在这里加强一点答案。

我已经尝试过 VS2019 并且它在那个 IDE 中工作，所以它应该与 VSCode 有关。 我已经搜索了其他答案，我找到了这个。

vscode launch.json debug and open specific url

解决我的问题的是转到 .vscode/launch.json 文件并附加：

         "launchBrowser": {
            "enabled": true,
            "args": "${auto-detect-url}",
            "windows": {
                "command": "cmd.exe",
                "args": "/C start ${auto-detect-url}/swagger"
            }

正如 Anton Dremin 所述，只需将上述内容添加到配置部分即可。

问题在于 Visual Studio for Mac。我能够获得正确的 URL 机会Run With>Custom Configuration > Run Action --> Debug .Net Core Debugger

当您创建新的 ASP.Net Core Web API 项目时，您会看到在项目属性中有 Launch browser 设置为 api/values 路径。因此，您可以将其更改为您想要的任何网址，也可以在您的 launchSetting.json 文件中进行更改

{
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false, 
    "anonymousAuthentication": true, 
    "iisExpress": {
      "applicationUrl": "http://localhost:54356",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "api/values",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "WebApplication4": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "api/values",
      "applicationUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

所以您会在配置文件部分看到将有 2 个配置。一种是用于 IIS express（使用 Visual Studio 运行代码时）和 WebApplication4（使用 dotnet run 运行项目时），因此您可以更改为

{
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false, 
    "anonymousAuthentication": true, 
    "iisExpress": {
      "applicationUrl": "http://localhost:54356",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "WebApplication4": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "swagger",
      "applicationUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

所以当你使用 VS 运行项目或dotnet run 命令时，总是会先提供 swagger url。
