Can't load html file with LoadHTMLGlob in production build. It's working in development-CodePudding

I'm using the Go Gin package in my rest-API service. To add some data I used HTML file to submit the form with data. In development, it's working, but in the production build server not working, if I commented 'LoadHTMLGlob' block server working again. I think 'LoadHTMLGlob' can't load HTML. Please help to solve this issue.

my main.go file:

package main

import (
    "ct-merchant-api/Config"
    "ct-merchant-api/Routes"
    "fmt"
    "github.com/jinzhu/gorm"
)
var err error

func main() {
    Config.DB, err = gorm.Open("mysql", Config.DbURL(Config.BuildDBConfig()))

    if err != nil {
        fmt.Println("Status:", err)
    }
    defer Config.DB.Close()

    r := Routes.SetupRouter()
    
    // Load HTML   
    r.LoadHTMLGlob("templates/*")
    
    //running
    runningPort := Config.GetServerInfo()
    _ = r.Run(":"   runningPort.ServerPort)
}

Route file:

package Routes

import (
    "ct-merchant-api/Controllers/Referral"
    "github.com/gin-contrib/cors"
    "github.com/gin-gonic/gin"
    "net/http"
)

func SetupRouter() *gin.Engine {
    api := gin.Default()
    config := cors.DefaultConfig()
    config.AllowAllOrigins = true
    config.AllowCredentials = true
    config.AddAllowHeaders("authorization")
    api.Use(cors.New(config))

    api.GET("/", func(c *gin.Context) {
        c.String(http.StatusOK, "Welcome to GO-rib Server")
    })

    api.GET("/referral/:merchantId", Referral.LeadForm)
    api.POST("/add-lead", Referral.LeadAdd)

    return api
}

For Deployment I Create a service go-web-api.service in /lib/systemd/system

In go-web-api.service file:

[Unit]
Description=goweb

[Service]
Type=simple
Restart=always
RestartSec=5s
ExecStart={my_project_build_file_path}

[Install]
WantedBy=multi-user.target

CodePudding user response：

You need to add WorkingDirectory to your system file

[Service]
Type=simple
Restart=always
RestartSec=5s
WorkingDirectory=/path/to/your/project //add this line
ExecStart={my_project_build_file_path}
