"Mastering Data Transmission in Angular 2: A Guide to Sending Data via HTTP Services

My challenge involves processing an array of URLs by sending them to an HTTP service as part of the URL path and then generating results based on the response type. The example array I have is:

this.urlArray = ["www.test.com","www.test2.com"];

Basically, I am iterating over the array, creating a div for each URL, and then sending the URL to the HTTP service as a parameter. Based on the response type (such as "time-out", success, or error), I need to dynamically change the color of the div. Could anyone provide guidance on how to approach this task?
