如何读取ASP.NET vNext从Config.json的AppSettings值 [英] How to read AppSettings values from Config.json in ASP.NET vNext

问题描述

我已经得到了我的AppSettings设置在Config.json是这样的：

I have got my AppSettings setup in Config.json like this:

{
  "AppSettings": {
        "token": "1234"
    }
}

我在网上搜索如何读取config.json的AppSettings值，但我无法得到任何有用的东西。

I have searched online on how to read AppSettings values from config.json but I could not get anything useful.

我试过：

var configuration = new Configuration();
var appSettings = configuration.Get("AppSettings"); // null
var token = configuration.Get("token"); // null

我知道与ASP.NET 4.0，你可以这样做：

I know with ASP.NET 4.0 you can do this:

System.Configuration.ConfigurationManager.AppSettings["token"];

但我怎么做到这一点的ASP.NET vNext？

But how do I do this in ASP.NET vNext?

推荐答案

您必须首先注册您的配置文件：

You first have to register your config file:

public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv)
{
     // Setup configuration sources.
     Configuration = new Configuration(appEnv.ApplicationBasePath)
     .AddJsonFile("config.json")
     .AddEnvironmentVariables();
}

然后查询数据：

var token = configuration.Get<string>("AppSettings:token");

您需要的依赖添加到您的 project.config 文件：

You'll need to add a dependency to your project.config file:

"dependencies": {
    "Microsoft.Framework.ConfigurationModel.Json": "1.0.0-beta7",
}

和获得的NuGet包。
