【问题描述】：

我正在尝试在我的网关应用程序中使用 Yarp 来路由我的应用程序。但是，一旦启动，我就会收到“Route '0' requires Hosts or Path specified. Set the Path to '/{**catchall}' to match all requests.”

这是我的 AppSettings 文件：

 "ReverseProxy": {
    "Routes": [
      {
        "SampleService": {
          "ClusterId": "SampleService-cluster1",
          "Match": {
            "Host": "localhost",
            "Path": "sample/{**catchall}"
          }
        },
        "NotificationService": {
          "ClusterId": "NotificationService-cluster",
          "Match": {
            "Host": "localhost",
            "Path": "api/NotificationService/{**catchall}"
          }
        }
      }
    ],
    "Clusters": {
      "SampleService-cluster1": {
        "Destinations": { "SampleService-cluster1/destination1": { "Address": "http://127.0.0.1:6500" } }
      },
      "NotificationService-cluster": {
        "Destinations": { "NotificationService-cluster/destination1": { "Address": "http://*:6020" } }
      }
    }
  }

配置服务：

public void ConfigureServices(IServiceCollection services)
        {
            services.AddHttpClient();
            services.AddCors(options =>
            {
                options.AddPolicy("any", builder =>
                {
                    builder.AllowAnyOrigin()
                           .AllowAnyMethod()
                           .AllowAnyHeader();
                });
            });

            services.AddControllers();

            services.AddTelemetryConsumer<ForwarderTelemetry>();

            services.AddReverseProxy()
                .LoadFromConfig(Configuration.GetSection("ReverseProxy"));
        }

我明白了： System.InvalidOperationException

那么知道如何解决这个问题吗？

【解决方案1】：

v1.0.0-preview11 中对 Routes 的配置方式进行了重大更改。您需要更新您的设置。

"ReverseProxy": {
  "Routes": {
    "SampleService": {
      "ClusterId": "SampleService-cluster1",
      "Match": {
        "Host": "localhost",
        "Path": "sample/{**catchall}"
      }
    },
    "NotificationService": {
      "ClusterId": "NotificationService-cluster",
      "Match": {
        "Host": "localhost",
        "Path": "api/NotificationService/{**catchall}"
      }
    }
  },
  "Clusters": {
    "SampleService-cluster1": {
      "Destinations": { "SampleService-cluster1/destination1": { "Address": "http://127.0.0.1:6500" } }
    },
    "NotificationService-cluster": {
      "Destinations": { "NotificationService-cluster/destination1": { "Address": "http://*:6020" } }
    }
  }
}
