ASP.NET CORE读取APPSETTINGS.JSON的配置

1、首先在appsettings文件中添加我们的其他常用配置信息

  "Setting": {
    "oa_ff": "https://www.oa.com/",
    "crm_ff":"123465"
  }

2、
再创建一个实体类Setting

public class Setting
    {
        public string oa_ff { get; set; }
        public string crm_ff{ get; set; }
    }

3、startup.cs启动类中public void ConfigureServices方法增加

services.AddOptions();
            services
                .Configure<Setting>(Configuration.GetSection("Setting"));  //此处的Setting类是自己新建的，内容要和appsetting.json中Setting节点里字段对应起来方便以后访问

4、在控制器中中定义上下文及setting

//定义上下文
        private readonly db_oa_depContext _context;
        private readonly IOptions<Setting> _appSettings;

        public WorkFlowController(db_oa_depContext context, IOptions<Setting> appSettings)
        {
            this._context = context;
            this._appSettings = appSettings;
        }

5、控制器中访问：_appSettings.value.属性  就可以出来了
