Ocelot 发布请求未通过

Question

我在我的项目中实现了 Ocelot API 网关，该网关对“GET”请求运行良好，但是当我尝试发送“POST”请求时出现错误：

previousRequestId：没有以前的请求 ID，消息：错误代码：UnableToFindDownstreamRouteError 消息：无法匹配上游路径的 ReRoute 配置：/api/patient/CreateAppointment，动词：POST。在 ResponderMiddleware 中发现错误。请求路径设置错误响应：/api/patient/CreateAppointment，请求方法：POST

以下是我的ocelot.json：

{
  "Routes": [
    {
      "DownstreamPathTemplate": "/api/patient/{everything}",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "patientservice",
          "Port": 81
        }
      ],
      "UpstreamPathTemplate": "/api/patient/{everything}",
      "UpstreamHttpMethod": [ "GET", "POST" ],
      "UpstreamHost": "*"
    },
    {
      "DownstreamPathTemplate": "/api/actor",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "postgresqldapper",
          "Port": 5001
        }
      ],
      "UpstreamPathTemplate": "/api/actor",
      "UpstreamHttpMethod": [ "GET" ]
    },
    {
      "DownstreamPathTemplate": "/api/product/{everything}",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "productservice",
          "Port": 80
        }
      ],
      "UpstreamPathTemplate": "/api/product/{everything}",
      "UpstreamHttpMethod": [ "GET" ]
    },
    {
      "DownstreamPathTemplate": "/api/weatherforecast",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "postgresqldapper",
          "Port": 5001
        }
      ],
      "UpstreamPathTemplate": "/api/weatherforecast",
      "UpstreamHttpMethod": [ "GET" ]
    },
    {
      "DownstreamPathTemplate": "/api/user",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "loginservicedapr",
          "Port": 80
        }
      ],
      "UpstreamPathTemplate": "/api/user",
      "UpstreamHttpMethod": [ "GET" ]
    },
    {
      "DownstreamPathTemplate": "/api/user/{everything}",
      "DownstreamScheme": "http",
      "DownstreamHostAndPorts": [
        {
          "Host": "loginservicedapr",
          "Port": 5001
        }
      ],
      "UpstreamPathTemplate": "/api/user/{id}",
      "UpstreamHttpMethod": [ "GET" ]
    }

  ],
  "GlobalConfiguration": {
    "RequestIdKey": "OcRequestId",
    "AdministrationPath": "/administration"
  }
}

当直接从 Swagger 或 Postman 调用时，我执行“POST”请求的 API 对于“POST”请求运行良好。

请让我知道我应该在 ocelot.json 文件中更改什么以便“POST”请求可以通过？

Answer 1

您的错误实际上是说 Ocelot 无法将请求路由到

POST /api/patient/CreateAppointment

在您的屏幕截图中，您的 curl 命令（正在运行）是一个请求：

POST /api/patient

您的/{everything} 路径后缀告诉 Ocelot，无论您调用网关使用的任何后缀都将出现在下游服务中。

我的理论是您没有在下游患者服务 API 上定义 CreateAppointment 端点操作。在您的服务上定义此路径后，您的 /api/patient/{everything} 路由映射应该可以正常工作。
