在ASP.NET Core中读取环境变量 [英] Read environment variables in ASP.NET Core

问题描述

使用 DNX 运行我的ASP.NET Core应用程序，我能够从命令行设置环境变量，然后像这样运行它:

Running my ASP.NET Core application using DNX, I was able to set environment variables from the command line and then run it like this:

set ASPNET_ENV = Production
dnx web

在1.0中使用相同的方法:

Using the same approach in 1.0:

set ASPNETCORE_ENVIRONMENT = Production
dotnet run

不起作用-应用程序似乎无法读取环境变量.

does not work - the application does not seem to be able to read environment variables.

Console.WriteLine(Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT"));

返回空值

我想念什么?

推荐答案

您的问题是=周围的空格.

Your problem is spaces around =.

这将起作用:

Console.WriteLine(Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT "));

或删除空格(最好，请参见下面的@Isantipov的评论):

Or remove spaces (better, see comment of @Isantipov below):

set ASPNETCORE_ENVIRONMENT=Production
