Dynamics 365 Business Central: How to quickly check if a Url is secure (Use https) via AL

Hi, Readers.
Today I would like to share another mini tip about Business Central, how to quickly check if a Url is secure (Use https) via AL

Hypertext transfer protocol secure (HTTPS) is the secure version of HTTP, which is the primary protocol used to send data between a web browser and a website. HTTPS is encrypted in order to increase security of data transfer. This is particularly important when users transmit sensitive data, such as by logging into a bank account, email service, or health insurance provider.

In Business Central customization, we can directly open external websites, or customize some functions through external services and APIs. For example, Using Hyperlink() Method to open a URL in a current session without opening a new tab in the browser

Generate barcode through external services/APIs (Telepen, Swiss QR Code, QR codes with colors, images or text……)

Before using it, it is important to confirm whether the URL is secure in advance. Here is a standard method that can be used.

In codeunit 1299 “Web Request Helper”: procedure IsSecureHttpUrl(Url: Text)

Let’s do a simple test: When entering the Home Page on the customer card, check if it is secure.

Great.

The URI is not secure.

Very simple, give it a try!!!😁

Test code:

tableextension 50112 CustomerExt extends Customer
{
    fields
    {
        modify("Home Page")
        {
            trigger OnBeforeValidate()
            var
                WebRequestHelper: Codeunit "Web Request Helper";
            begin
                if Rec."Home Page" <> '' then
                    WebRequestHelper.IsSecureHttpUrl(Rec."Home Page");
            end;
        }
    }
}

PS:
1. This method also checks if the URL is valid, so it is very helpful when calling external services or web pages in AL.

The URI is not valid.
