cloudinary.NewFromURL does not work for custom domains

Bug report for Cloudinary Go SDK

cloudinary.NewFromURL does not work for custom domains as it returns an instance of cloudinary where further operations return URLs that do not exist.

Issue Type (Can be multiple)

• Build - Cannot install or import the SDK
• Performance - Performance issues
• Behaviour - Functions are not working as expected (such as generate URL)
• Documentation - Inconsistency between the docs and behaviour
• Other (Specify)

Steps to reproduce

package main

import (
	"context"
	"fmt"
	"github.com/cloudinary/cloudinary-go"
	"log"
)

func main() {
       // fake domain and publicId to showcase the issue
	cld, err := cloudinary.NewFromURL("https://cms.cloudinary.my-domain.com/image/upload/v1623180876/folder-1/folder-2/my-image.png")
	if err != nil {
		log.Fatalf("Failed to intialize Cloudinary, %v", err)
	}

	i, err := cld.Image("folder-1/folder-2/my-image")
	i.Transformation = "w_500"
	myURL, err := i.String()
	fmt.Println(myURL)
}

The above code prints this URL:

https://res.cloudinary.com/cms.cloudinary.my-domain.com/image/upload/w_500/v1/folder-1/folder-2/my-image?_a=AQAK9cJ

which returns 404.

Hi,

You should pass CLOUDINARY_URL to cloudinary.NewFromURL("") which initialises your Go environment with the correct credentials to talk to our API. This URL can be found in your Dashboard.

If you are trying to set up a custom domain for your images, then you should add a secure_cname parameter to your CLOUDINARY_URL.

So e.g.

cld, err := cloudinary.NewFromURL("cloudinary://<api_key>:<api_secret>@<cloud_name>?secure_cname=my.cname.com")

Hope this helps.
Thanks

Oh, thanks for the response. It was not clear from the documentation what the format was. Could you update the documentation and give this example?
Thanks!

Happy to see that it was helpful.
I will ask to update the documentation with the following examples as well.
Thanks!
