Build go plugin with .env file

[louistwiice]

Hello guyz !

I need to send global parameter to my plugin when running it, so for that, the solution I found is to create en .env file (Maybe there is an other solution. If yes I will take it). So I would like to know if it is possible to build go plugin and link it to an .env file.

I have a simple plugin

My go file

package main

import (
	"encoding/json"
	"fmt"
	"net/http"
	"os"

	"github.com/TykTechnologies/tyk/log"
	_ "github.com/lib/pq"
	"github.com/joho/godotenv"
)

type AuthDBConfig struct {
	DBHost 		string `json:"db_host"`
	DBPort 		int     `json:"db_port"`
	DBUser		string  `json:"db_user"`
	DBPassword	string  `json:"db_password"`
	DBName		string  `json:"db_name"`
}

var logger = log.Get()

func SimpleMiddleware(w http.ResponseWriter, req *http.Request) {
    err := godotenv.Load("local.env")
    if err != nil {
	logger.Error("some error occured. Err: %s", err)
	return
    }
    logger.Info("*** Authorizarion checking! ***")


    logger.Info(fmt.Sprintf("User %s authenticated succesfully", user_id))
    req.Header.Add("Foo", "Bar")
    req.Header.Add("UserID", user_id)
    req.Header.Add("FirstName", os.Getenv("FIRST_NAME"))
    req.Header.Add("LastName", os.Getenv("LAST_NAME"))
}

func main() {}

func init() {
	logger.Info("--- Go custom plugin v4 init successful! ---- ")
}

My local.env file

FIRST_NAME=something
LAST_NAME=link

building plugin
docker run --rm -v `pwd`:/plugin-source tykio/tyk-plugin-compiler:v4.1.0 plugin.so

But when I run Tyk with the plugin installed, it crashes.

Do you know how to do this please

Thanks a lot for your help
