Question content

I get the data from the database and they display the same in browser or software like postman

/ 20221125143847
// http://localhost:3000/api/v1/datesmain/read

{

"alldates": [
{
  "id": 1,
  "createdat": "2022-11-25t00:00:00z",
  "updatedat": "2022-11-25t00:00:00z",
  "deletedat": null,
  "volume": "20",
  "image_url": "/assets/images/img_3429.jpg\n",
  "average_weight": 7.5,
  "dates_type_id": 1,
  "wight_type_id": 1
},
{
  "id": 2,
  "createdat": "2022-11-25t00:00:00z",
  "updatedat": "2022-11-25t00:00:00z",
  "deletedat": null,
  "volume": "15",
  "image_url": "/assets/images/img_3436.jpg\n",
  "average_weight": 7.5,
  "dates_type_id": 1,
  "wight_type_id": 1
}
  ]
}

As you can see the image urls are correct and all the images are located in a folder under the root of the project with the name "assets" Because I don't understand it's possible to display my image through this url

http://localhost:3000/api/v1/datesmain/assets/images/img_3429.jpg

I want to display them all as a list view on the front end using java or...

But when copying and pasting a URL in the browser like this

// http://localhost:3000/api/v1/datesmain/static/images/img_3429.jpg
{
"message": "not found"
}

How can I solve this problem?

This is my little code

func ReadAllDatesMain(e echo.Context) error {
ad, err := logic.ReadAllDatesMain()
if err != nil {
    return nil
}
return e.JSON(http.StatusOK, map[string]interface{}{
    "alldates": ad,
})

}

Solution

You have defined a route for the API, but not for the file. You need to set static routing in echo. You can then access the folder structure via URL from a browser or a client such as Postman.
