Asp.net 如何设置环境名称(IHostingEnvironment.EnvironmentName)

发布于09月12日

默认的ASP.NET Core Web项目在Startup.cs中包含以下行:

if (string.Equals(env.EnvironmentName, "Development", StringComparison.OrdinalIgnoreCase))
{
    app.UseBrowserLink();
    app.UseDeveloperExceptionPage(ErrorPageOptions.ShowAll);
}
else
{
    app.UseExceptionHandler("/Home/Error");
}

据我所知，EnvironmentName是处理开发/生产环境的一种新方法.但它不会在发布构建配置上改变.那么，如何设定一个不同的EnvironmentName？

我可以想象应该在"命令"中将其设置为服务器的参数.

推荐答案

launchsettings.json个

At Properties > launchsettings.json

就像这样:

    {
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:1032/",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production"
      }
    },
    "WebAppNetCore": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "web": {
      "commandName": "web",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}
