参考的appsettings.json

{  "ConnectionString": "Server=tcp:127.0.0.1,5433;Database=Microsoft.eShopOnContainers.Services.IdentityDb;User Id=sa;Password=Pass@word;",  "IsClusterEnv": "False",  "MvcClient": "http://localhost:5100",  "SpaClient": "http://localhost:5104",  "XamarinCallback": "http://localhost:5105/xamarincallback",  "UseCustomizationData": false,  "Logging": {    "IncludeScopes": false,    "LogLevel": {      "Default": "Trace",      "System": "Information",      "Microsoft": "Information"    }  },  "ApplicationInsights": {    "InstrumentationKey": ""  },  "UseVault": false,  "Vault": {    "Name": "eshop",    "ClientId": "your-clien-id",    "ClientSecret": "your-client-secret"  }}

获取方式

1. Configuration["ConnectionString"]//直接获取是这个名称key的值

2. Configuration.GetValue<string>("IsClusterEnv")

3. Configuration["Vault:Name"] //获取嵌套的属性的,多级需要写多个,推荐第一种

4. Configuration.GetSection("Logging")

5. services.Configure<AppSettings>(Configuration);//实体类对象封装,json转换成对象

　　　　publicclassAppSettings

    {

        publicstring MvcClient { get; set; }

        publicbool UseCustomizationData { get; set; }

 

    }
