Asp.net Net Core 2.0正在查找appsettings.Production.json

我已经创建了两个这样的.net core 2 web应用程序，在此之前没有任何问题

在IISExpress下运行local时运行正常，但当我将调试版本部署到服务器上的IIS文件夹时，我遇到了问题

当我读取配置条目时，找不到它：

_config["MySettings:MyName"];

文件内容：

appsettings.Development.json

如果我复制appsettings.Development.json并重命名为appsettings.Production.json，它就会工作

我更改了prod文件中“MyName”的值并将其记录下来。是的，从appsettings.Production.json读取

---

如何以及为什么？没有在任何地方定义生产。

默认的

ConfigurationBuilder

正在查找

appsettings..json

文件，因此根据您使用的环境，此文件的名称会发生更改。当您在IIS Express中时，您处于

开发中

，当您部署应用程序时，您的环境是

生产环境

。这就是为什么需要

appsettings.Production.json

---

调试时，有一个名为

ASPNETCORE\u Environment

的环境变量被设置为

Development

，在部署中未设置

ASPNETCORE\u Environment

，默认值为

Production
，将环境更改为Production。我看不到在任何地方设置了任何环境变量。如果未设置
ASPNETCORE\u ENVIRONMENT
，它将默认为
Production
。这有文档记录吗？@ginalster有，这是链接
