how to create dinamic port in golang (echo framwork)

问题

我在这里为你翻译代码部分：

  1. package config
  3. import (
  4. 	"fmt"
  5. 	logger "github.com/sirupsen/logrus"
  6. 	"gorm.io/driver/postgres"
  7. 	"gorm.io/gorm"
  8. )
  10. func DatabaseConnect() *gorm.DB {
  11. 	DBURL := fmt.Sprintf("host=%s port=%s user=%s dbname=%s sslmode=disable password=%s", pkg.GodotEnv("DB_HOST"), pkg.GodotEnv("DB_PORT"), pkg.GodotEnv("DB_USER"), pkg.GodotEnv("DB_NAME"), pkg.GodotEnv("DB_PASSWORD"))
  13. 	db, err := gorm.Open(postgres.Open(DBURL), &gorm.Config{})
  15. 	if err != nil {
  16. 		defer logger.Info("Database connection failed")
  17. 		logger.Fatal(err)
  18. 		return nil
  19. 	}
  21. 	return db
  22. }

和 main.go：

  1. func main() {
  2. 	e := echo.New()
  3. 	db := config.DatabaseConnect()
  4. 	middleware.WebSecurityConfig(e)
  5. 	routes.NewRoute(db, e)
  6. 	e.Logger.Fatal(e.Start(":8080"))
  7. }

你想要创建一个像下面示例中的动态路由：

  1. server.Initialize(os.Getenv("DB_DRIVER"), os.Getenv("DB_USER"), os.Getenv("DB_PASSWORD"), os.Getenv("DB_PORT"), os.Getenv("DB_HOST"), os.Getenv("DB_NAME"))
  3. server.Run(":" + os.Getenv("PORT"))

如何创建动态端口服务器？谢谢。

英文:

i have package config.go in this my code

  2. package config
  3. import (
  4. 	"fmt"
  5. 	logger "github.com/sirupsen/logrus"
  6. 	"gorm.io/driver/postgres"
  7. 	"gorm.io/gorm"
  8. )
  9. func DatabaseConnect() *gorm.DB {
  10. DBURL := fmt.Sprintf("host=%s port=%s user=%s dbname=%s sslmode=disable password=%s", pkg.GodotEnv("DB_HOST"), pkg.GodotEnv("DB_PORT"), pkg.GodotEnv("DB_USER"), pkg.GodotEnv("DB_NAME"), pkg.GodotEnv("DB_PASSWORD"))
  12. 	db, err := gorm.Open(postgres.Open(DBURL), &gorm.Config{})
  14. 	if err != nil {
  15. 		defer logger.Info("Database connection failed")
  16. 		logger.Fatal(err)
  17. 		return nil
  18. 	}
  20. 	return db
  21. }

and main.go

  1. func main() {
  2. 	e := echo.New()
  3. 	db := config.DatabaseConnect()
  4. 	middleware.WebSecurityConfig(e)
  5. 	routes.NewRoute(db, e)
  6. 	e.Logger.Fatal(e.Start(":8080"))
  7. }

I want to create a dynamic routing like the example below :

  1. server.Initialize(os.Getenv("DB_DRIVER"), os.Getenv("DB_USER"), os.Getenv("DB_PASSWORD"), os.Getenv("DB_PORT"), os.Getenv("DB_HOST"), os.Getenv("DB_NAME")) 
  3. server.Run(":" + os.Getenv("PORT"))

how to create dinamic port server ? thanks

请看这个链接：https://github.com/joho/godotenv。

将应用程序的配置添加到项目根目录下的.env文件中：

  1. DB_DRIVER=mysql
  2. DB_USER=root
  3. ...

然后在你的Go应用程序中可以这样做：

  1. package main
  3. import (
  4.     "log"
  5.     "os"
  7.     "github.com/joho/godotenv"
  8. )
  10. func main() {
  11.   err := godotenv.Load()
  12.   if err != nil {
  13.     log.Fatal("加载.env文件时出错")
  14.   }
  16.   driver:= os.Getenv("DB_DRIVER")
  17.   user:= os.Getenv("DB_USER")
  18.   // todo
  20. }

Check this out: https://github.com/joho/godotenv.

Add your application configuration to your .env file in the root of your project:

  1. DB_DRIVER=mysql
  2. DB_USER=root
  3. ...

Then in your Go app you can do something like:

  1. package main
  3. import (
  4.     "log"
  5.     "os"
  7.     "github.com/joho/godotenv"
  8. )
  10. func main() {
  11.   err := godotenv.Load()
  12.   if err != nil {
  13.     log.Fatal("Error loading .env file")
  14.   }
  16.   driver:= os.Getenv("DB_DRIVER")
  17.   user:= os.Getenv("DB_USER")
  18.   // todo
  20. }
