go-micro kubernetes greeter 示例 - 无法访问 greeter api 服务

Question

我正在尝试让这个 go-micro greeter 示例在 Kubernetes 上运行 https://github.com/micro/examples/tree/master/greeter

我可以在 docker 中本地运行它。但是，当我尝试通过 Kubernetes (http://{{external-ip}}/greeter/say/hello) 访问 greeter api 服务时，出现错误:{"id":"go.micro.api", "code":500,"detail":"not found","status":"内部服务器错误"

为了进行故障排除，我简化了场景，我只是希望能够通过 micro api 调用 go-micro api 服务。以下是我的设置:

API.go

package main

import (
    "github.com/micro/go-micro"
    api "github.com/micro/micro/api/proto"
    "log"
    k8s "github.com/micro/kubernetes/go/micro"

    "context"
)

type Say struct {
}

//I just want to access this via the micro api on k8s via services external ip
func (s *Say) Hello(ctx context.Context, req *api.Request, rsp *api.Response) error {
    rsp.StatusCode = 200
    rsp.Body = "Hello"
    return nil
}

func main() {
    service := k8s.NewService(
        micro.Name("default.greeter-api"),
    )

    service.Init()

    service.Server().Handle(
        service.Server().NewHandler(
            &Say{},
        ),
    )

    if err := service.Run(); err != nil {
        log.Fatal(err)
    }
}

您的配置一切正常。

http://{{external-ip}}/greeter/say/hello), I get the error: {"id":"go.micro.api","code":500,"detail":"not found","status":"Internal Server Error"}

您在请求中只错过了端口号 8080，并尝试调用 rpc 服务而不是 greeter-api。
