.net core 2.0 读取配置文件

1.引用Microsoft.Extensions.Configuration2.在Startup中注入服务

public static IConfiguration Configuration { get; private set; } public Startup(IConfiguration configuration) { Configuration = configuration; } public void ConfigureServices(IServiceCollection services) { //添加服务 services.AddUrlResolve(Configuration); }

扩展方法AddUrlResolve如下

/// <summary> /// 拓展方法 /// </summary> public static class Extensions { /// <summary> /// 为了保留IConfiguration /// </summary> /// <param name="services"></param> /// <param name="config"></param> public static void AddUrlResolve(this IServiceCollection services, IConfiguration config) { services.Add(new ServiceDescriptor(typeof(UrlResolveService), typeof(UrlResolveService), ServiceLifetime.Singleton)); //读取配置文件 UrlResolveService.ApiUrl = config["ApiUrl"]; UrlResolveService.AuthorityUrl = config["AuthorityUrl"]; } } /// <summary> /// 读取配置文件的服务 /// </summary> public class UrlResolveService { public static string AuthorityUrl { get; set; } public static string ApiUrl { get; set; } public string GetAuthorityUrl() { return AuthorityUrl; } public string GetApiUrl() { return ApiUrl; } }

3.使用UrlResolveService服务

public async Task<IActionResult> Call(UrlResolveService urlResolveService) { //API对应网址 var apiUrl = urlResolveService.GetApiUrl(); //...... }

4.配置文件

{ //授权网址 "AuthorityUrl": "http://localhost:5000/", //API网址 "ApiUrl": "http://localhost:5001/", }
