使用ocelot作为api网关

• 新建网站项目然后添加ocelot 的nuget包
• 新建ocelot.json的网关的配置文件

  {
    "GlobalConfiguration": {
      "BaseUrl": "https://api.mybusiness.com"
    },
    "ReRoutes": [
      {
        "DownstreamPathTemplate": "/api/values",
        "DownstreamScheme": "http",
        "DownstreamHostAndPorts": [
          {
            "Host": "localhost",
            "Port":
          }
        ],
        "UpstreamPathTemplate": "/users",
        "UpstreamHttpMethod": [ "Get" ],
        "AuthenticationOptions": {
          "AuthenticationProviderKey": "finbook",
          "AllowedScopes": []
        }
      },
      {
        "DownstreamPathTemplate": "/connect/token",
        "DownstreamScheme": "http",
        "DownstreamHostAndPorts": [
          {
            "Host": "localhost",
            "Port":
          }
        ],
        "UpstreamPathTemplate": "/connect/token",
        "UpstreamHttpMethod": [ "Post" ]
      }
    ]
  }

• 添加配置文件进入netcore管道

      public class Program
      {
          public static void Main(string[] args)
          {
              BuildWebHost(args).Run();
          }
  
          public static IWebHost BuildWebHost(string[] args) =>
              WebHost.CreateDefaultBuilder(args)
                   .ConfigureAppConfiguration((hostingContext, builder) =>
                   {
                       builder
                       .SetBasePath(hostingContext.HostingEnvironment.ContentRootPath)
                       .AddJsonFile("Ocelot.json");
                   })
                  .UseStartup<Startup>()
                  .Build();
      }

         public void ConfigureServices(IServiceCollection services)
          {
              services.AddOcelot();
          }

• 集成identityserver

    services.AddAuthentication()
     .AddIdentityServerAuthentication(authenticationProviderKey, options=> {
                      options.Authority = "http://localhost:52619/";
                      options.ApiName = "geteway_api";
                      options.SupportedTokens = SupportedTokens.Both;
                      options.ApiSecret = "secret";
                      options.RequireHttpsMetadata = false;//是否是https请求
                  });
