1、在配置文件appsettings.json里新增AppSettings节点
{ "Logging": { "LogLevel": { "Default": "Warning" } }, "AppSettings": { "HttpUrl": "http://www.ehongcn.com", "Copyright": "山南远宏科技有限公司" }, "AllowedHosts": "*" }
2、新建实体类AppSettings,通常建在公共类库Common里
public class AppSettings { public string HttpUrl { get; set; } public string Copyright { get; set; } }
3、在Startup类里的ConfigureServices配置
services.Configure<AppSettings>(Configuration.GetSection("AppSettings"));
4、控制器或者业务类里使用
private readonly AppSettings _appSettings; public HomeController(IOptions<AppSettings> appSettings) { _appSettings = appSettings.Value; } public IActionResult Index() { ViewData["Url"] = _appSettings.HttpUrl; return View(); }
5、页面上使用
@using Microsoft.Extensions.Options; @using Demo.Common @inject IOptions<AppSettings> Settings @{ ViewData["Title"] = "Privacy Policy"; } <h1>@ViewData["Title"]</h1> <p>版权所属有 @Settings.Value.Copyright.</p>
