Question

我是golang的新手，我想构建我的第一个简单的Web应用程序。每次我想构建我的源代码时，都会收到错误locale import "./controllers" in non-local package"。

这是我的文件夹结构：

goTest
├── Dockerfile
├── controllers
│   └── IndexController.go
└── main.go

main.go文件：

package main

import (
    "github.com/julienschmidt/httprouter"
    "net/http"
    "log"
    "./controllers"
)

func main() {
    router := httprouter.New()
    router.GET("/", IndexController)

    log.Fatal(http.ListenAndServe(":8080", router))
}

IndexController.go文件：

package controllers

import (
  "fmt"
)

func IndexController(w http.ResponseWriter, r *http.Request, ps httprouter.Params) error {
    fmt.Fprintf(w, "Hi %s!", r.URL.Path[1:])
}

我的Dockerfile文件（从https://hub.docker.com/_/golang/复制）：

FROM golang:1.8

WORKDIR /go/src/app
COPY . .

RUN go-wrapper download   # "go get -d -v ./..."
RUN go-wrapper install    # "go install -v ./..."

EXPOSE 8080

CMD ["app"]

docker和go build命令：

docker build -t my-golang-app .

至少控制台输出：

我终于找到了这个问题。在eval文件中，我必须导入main.go而不是app/controllers，因为./controllers路径为Dockerfile。

GO - 本地导入无效
