How to get images path from golang project file

Question

I am a beginner in making a REST full API using golang, what I want to ask is to get an image file from the path in my golang project, before I have successfully uploaded the image and saved it in the path and the path I have saved it in mysql database, how do I do it to be able to display the image in the form of a link, so I can load it on android,

and how to make it like this "http: // localhost: 3004 / images / imagename.jpg" inside the json result ( ImgEvent )??

please help me... thanks

func (idb *InDB) GetEvents(c *gin.Context) {
    var (
        events    []structs.Event
        newEvents structs.Event
        result    gin.H
    )

    getimage := "img_event"
    data := idb.DB.Select(getimage).Find(&events)
    if data != nil {
        result = gin.H{
            "message": "Not found",
        }
    }
    newEvents.ImgEvent = getimage

    data = idb.DB.Find(&events)

    if len(events) <= 0 {
        result = gin.H{
            "result": nil,
            "count":  0,
        }
    } else {
        result = gin.H{
            "data": events,
        }
    }

    c.JSON(http.StatusOK, result)
}

You should a create a file server to be able create an http link for files. You can use net/http's Fileserver for the same. Fileserver is a good choice if you want it for a small time, like as long as you API server is running. Another choice would be to create an FTP server and use that to store images.
