部署到Heroku错误无法执行二进制文件Exec格式错误

如何解决部署到Heroku错误无法执行二进制文件Exec格式错误

我是Golang的新手，正在尝试将简单的rest api部署到Heroku。

在我构建代码并在本地运行heroku之后，该代码在本地工作。但是，当我将其推送到Heroku时，该代码不起作用。在浏览器中，我看到heroku的应用程序错误

我使用heroku日志--tail跟踪以下错误日志

错误代码为“无法执行二进制文件：执行格式错误”。我做了一次Google搜索，从我的阅读中得知编译版本不兼容。如果是这样，我该怎么做才能使正确的二进制文件在heroku上运行？谢谢

下面是我的server.go代码，以供参考

package main

import (
    "io"
    "net/http"
    "os"

    "github.com/gin-gonic/gin"
    "github.com/myhendry/goapi/controller"
    "github.com/myhendry/goapi/service"
)

var (
    videoService    service.VideoService       = service.New()
    videoController controller.VideoController = controller.New(videoService)
)

func setupLogOutput() {
    f,_ := os.Create("gin.log")
    gin.DefaultWriter = io.MultiWriter(f,os.Stdout)
}

func main() {
    setupLogOutput()

    server := gin.New()
    server.Use(gin.Logger())

    apiRoutes := server.Group("/api")
    {
        apiRoutes.GET("/videos",func(ctx *gin.Context) {
            ctx.JSON(200,videoController.FindAll())
        })

        apiRoutes.POST("/videos",func(ctx *gin.Context) {
            err := videoController.Save(ctx)
            if err != nil {
                ctx.JSON(http.StatusBadRequest,gin.H{"error": err.Error()})
            } else {
                ctx.JSON(http.StatusOK,gin.H{"message": "Video Input is Valid!!"})
            }

        })
    }

    port := os.Getenv("PORT")

    if port == "" {
        port = "5000"
    }

    server.Run(":" + port)
}

解决方法

在终端上的本地开发计算机Mac OS上编译

env GOOS=linux GOARCH=amd64 go build -o bin/golang-gin-poc -v .

然后推送到Heroku

我仍在寻找在Heroku上进行后期构建的解决方案
