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

本文介绍了如何设置环境名称 (IHostingEnvironment.EnvironmentName)?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

默认的 ASP.NET Core web 项目在 Startup.cs 中包含这样的行:

Default ASP.NET Core web project contain such lines in Startup.cs:

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

据我所知，EnvironmentName 是一种处理开发/生产环境的新方法.但它不会在发布构建配置上发生变化.那么如何设置不同的EnvironmentName?

As I understand, the EnvironmentName is a new way to handle Dev/Production environment. But it doesn't changes on Release build configuration. So what is the way to set a different EnvironmentName?

我可以想象它应该在命令"中设置为服务器的参数.

I can imagine that it should be set in "Commands" as a parameter for server.

推荐答案

launchsettings.json

在属性> launchsettings.json

At Properties > launchsettings.json

就像这样:

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